Powermonitor 3000 Unit Operations Chapter 3 Power Factor Results The power monitor calculates true, displacement and distortion power factor, each on a per-phase and total three-phase basis. True power factor is the ratio between the total true power and total apparent power (in percent), and takes into account the effect of phase shift between the voltage and current as well as any harmonics present.
Chapter 3 Powermonitor 3000 Unit Operations Power and Power Factor Results Parameter Description Range Units Phase 1 True Power Factor The ratio between the power and apparent power for an individual phase or all three phases; signed to show lead (+) or lag (-). -100…100 Percent The ratio between the magnitude of the fundamental and the sum of the magnitudes for all of the current harmonics for an individual phase or all three phases.
Powermonitor 3000 Unit Operations Chapter 3 Configurable Energy Counter Rollover You may configure the number of digits at which energy values roll over to zero. The parameter range is 4…15 digits. Configure this setting in Advanced Device Configuration by using the display module or by writing to the Advanced Device Configuration table on page 196. This setting lets you optimize the energy counter rollover for use with applications that support a limited number of significant digits.
Chapter 3 Powermonitor 3000 Unit Operations The utility may provide a pulse that indicates the end of each demand interval. The utility updates the demand value at the end of each interval and maintains the highest value obtained during any interval. This method is known as thermal demand. You may set up a power monitor to determine its demand interval from the utility pulse.
Powermonitor 3000 Unit Operations Chapter 3 Instantaneous The power monitor computes instantaneous demand by substituting the elapsed interval duration for the total interval duration (T) in the demand equation. It is therefore identical to the standard computation except it integrates the power only over the elapsed interval duration and calculates the average value over the elapsed duration. The modified equation thus becomes.

Chapter 3 Powermonitor 3000 Unit Operations Refer to the Device Configurations Summary table on page 50 for a summary of basic and advanced device configuration settings. You may use a copy of this table to record your configuration settings. Basic Device Configuration The basic unit configuration sets the wiring mode, PT ratios and CT ratios to match your power system. Every power monitor requires basic configuration.
Powermonitor 3000 Unit Operations Chapter 3 PT and CT Ratios You may directly connect the voltage inputs of the power monitor to power systems rated at 600V line-to-line or less. Above 600V, you need potential transformers (PTs) to step down the power system voltage to one that is measurable. Most commercially available PTs have a secondary rated voltage of 120V (150V full-scale). Nearly every power monitor installation requires CTs to step down the power system current to a value of 5 A full-scale.
Chapter 3 Powermonitor 3000 Unit Operations Advanced Device Configuration A number of parameters are grouped into Advanced Configuration, including the Password, demand and projected demand setup, relay and KYZ pulse operation setup, metering accuracy options, date/time and display module scrolling rate.

Projected Demand Type specifies the type of calculation used for projected demand.
Chapter 3 Powermonitor 3000 Unit Operations Metering Options Configuration parameters RMS Result Averaging, RMS Resolution and Frequency Averaging allow you to make choices to fit the power monitor more closely to your application needs. The default settings are to average 8 RMS and frequency calculations, providing a smoother result, and to sample at a high rate, providing greater accuracy where significant harmonics are present.
Powermonitor 3000 Unit Operations Chapter 3 Date and Time You may use these parameters to set the power monitor’s internal clock and calendar and configure the display format as MM/DD/YYYY (default) or DD/MM/YYYY. The power monitor uses its internal clock time-stamp entries in logs, oscillograms and transient captures. Display Mode Scroll Speed This parameter controls how fast text that doesn’t fit in the window is scrolled on the display module. Default is fast scrolling.
Chapter 3 Powermonitor 3000 Unit Operations Ethernet units also support synchronization of their internal clocks from up to three SNTP servers, at a configurable synchronization interval. Since SNTP servers operate in UTC (Universal Coordinated Time), a time zone for the power monitor must also be configured for the correct time to be set. The time zone is configured as an offset in hours from UTC (formerly known as GMT).
Powermonitor 3000 Unit Operations Chapter 3 SNTP Address 2 The IP address of the primary SNTP server, accessed as the 1st…4th octet. SNTP Address 3 The IP address of a third SNTP server, accessed as the 1st…4th octet.
Chapter 3 Powermonitor 3000 Unit Operations DST (Daylight Saving Time) Configuration The power monitor may be configured to automatically adjust its internal clock for daylight saving time. You may configure the daylight saving time function by using the display module or via communication by writing to the Daylight Saving Time Configuration table. DST Enable Enables the daylight saving time function.
Powermonitor 3000 Unit Operations Chapter 3 DST is disabled by default. When enabled, the default start time is 2:00 a.m. on the second Sunday in March, and the default end time is 2:00 a.m. on the first Sunday in November. This corresponds to US Daylight Saving Time beginning in 2007.
Chapter 3 Powermonitor 3000 Unit Operations Metering Update Rate The metering update rate is a measure of how often the power monitor calculates new metering results. The metering update rate is not significant in most applications, but can be important in some control applications. The metering update rate affects how quickly a setpoint can respond to an electrical event and affects how often new metering results are available for communication.
Powermonitor 3000 Unit Operations Chapter 3 Out-of-the-box metering update rates are based on factory-default configuration data and are listed in the Meter Update Rate with Factory Default Configuration table for all power monitor models and communication options. Factory default settings for configuration parameters can be found in Appendix A.

You must configure the communication parameters before you connect your power monitor to an Ethernet network. See your network administrator for assistance in setting the communication options.
Communication Chapter 4 In this example, the NetID is 192.1.1.0 and the HostID is 0.0.0.207. The relationship between NetID and HostID depends on the IP address class, the discussion of which is beyond the scope of this document (the example uses a Class C IP address). Devices on the same subnet can communicate directly; devices on different subnets may communication with each other only through a gateway or router.
Chapter 4 Communication Data Messaging Overview Through communication, the power monitor becomes an effective source of power and energy data to enterprise information and automation systems. This section of the manual provides an overview of data messaging with the power monitor. Following the overview, discussions will focus on the details of messaging using specific communication types (for example, serial, remote I/O, DeviceNet, and Ethernet). The power monitor is a read/write data server.
Communication Chapter 4 Powermonitor 3000 Unit Data Table Attributes Powermonitor 3000 unit data table attributes include their addressing, data access, number of elements, data type, and user-configurability. Address - Data tables are addressed in a number of ways, depending on the type of communication and the protocol being used.
Chapter 4 Communication Let’s look at the Date and Time table as an example. • • • • • • • • CSP file number: N11 Remote I/O BT length: 12 CIP assembly instance: 6 (Write) or 7 (Read) Data table name: Date and Time Data access: Read/write Number of elements: 8 Data type: Integer User-configurable: No The power monitor data tables are listed in Appendix A. The table on page 188 shows a summary of all the data tables.
Communication Chapter 4 Timestamp format. The power monitor expresses timestamps in an array of four data table elements: Year, Month/Day, Hour/Minute, Second/ Hundredth of a second Each timestamp parameter (except the Year) is a combination of its first and second element. For instance, the Month is the parameter value divided by 100 and the remainder is the Day. Example: 1230 = December 30th. The timestamp data type may be integer or floating-point and depends on the data table.
Chapter 4 Communication A valid write to a data table must meet the following general criteria: • The length of the source data array must equal the data table length. Note that the same data table may have a different length in various power monitor models. • The entire data table must be written in one pass. • The first element in the source data array must generally contain the correct password (or a value of -1 for read-back data selection).
Communication Chapter 4 Data Table Write Flow Diagram Programmable Controller (Data Client) Powermonitor 3000 (Data Server) Allen-Bradley Element 0 1 2 3 4 5 ... n Element 0 1 2 3 4 5 ...
Chapter 4 Communication Single Element Data Writes A single element write to a data table must meet the following general criteria: • A valid password is written to Table 60, element 0 to enable single element writes. • The source and destination data type and length must match, for example, floating point or integer, 4 bytes or 2 bytes. • The source data element must be within the legal range listed in the data table specification. • Reserved elements may not be written.
Communication Chapter 4 Simple Reads of Data Tables The following considerations apply to simple power monitor data table reads: • An entire data table or a contiguous portion (down to a single element) may be read, except for remote I/O and DeviceNet optional communication which require that an entire table be read • The target data location should match the size and data type of the data requested You may use simple reads to obtain basic metering data, configuration data, date and time, and the contents
Chapter 4 Communication Indexed Reads of Large Data Structures Large data structures that require indexed reads are most often read into a computer-based application that performs further processing of the data. The power monitor parses logs, oscillograms, harmonic analysis results, setpoint status results, and other large data structures into individual records to be read by the client and reassembled into the original data structure. You may select one of two modes for indexed table reads.
Communication Chapter 4 Indexed Data Read, Manual Mode Flow Diagram Refer to Chapter 5, Setpoint Programming and Operation; Chapter 7, Data Logging; and Chapter 8, Advanced Features for details of indexed mode data reads for each of these functions.
Chapter 4 Communication I/O Type Communication Powermonitor 3000 units with optional remote I/O, EtherNet/IP, ControlNet, and DeviceNet communication provide I/O type (implicit) messaging. Remote I/O units emulate a logical quarter rack on the I/O channel. The corresponding, two-word output and input image table elements are automatically scanned by the I/O scanner, and the data points they contain are available for use in the logic program of the controller associated with the I/O scanner.
Communication Chapter 4 Serial Communication Options The native RS-485 and optional RS-232 communication ports provide basic serial asynchronous communication capabilities. The RS-485 communication standard supports multi-drop communication between a master station and up to 31 slaves on a single network up to 1219 m (4000 ft) long. For satisfactory communication performance, however, we recommend connecting no more than 8…12 power monitors to an RS-485 multi-drop network.
Chapter 4 Communication IMPORTANT Because the floating-point word order in the ControlLogix controller is reversed from that in the power monitor, your ladder logic needs to reverse the word order so the data may be interpreted correctly. The swap byte (SWPB) instruction performs this function. Because of the DF1 protocol’s inherent handshaking, the completion of each message may be used to activate the next message, without any additional programmed delay.
Communication Chapter 4 The power monitor does not initiate Modbus commands but responds to commands sent by the Modbus master. The following Modbus function codes are supported: • 03 Read Holding Registers • 04 Read Input Registers • 16 Write Multiple Holding Registers • 08 Diagnostics – 00 Echo Command Data – 02 Return Diagnostic Counters – 10 Clear Diagnostic Counters • 06 Write Single Holding Register Function 06, 16 and the sub function 10 of function 08 support Broadcast packets.
Chapter 4 Communication The data table number of error request and element offset of error request in the Write Error Status table is updated with the first Modbus address of the table and element offset that the incoming request packet attempts to write to. Modbus Error Codes Error Code Description Meaning Response Exception Code 0 No error. None 1 Function Code The function does not support Broadcast. cannot Broadcast.
Communication Chapter 4 For function code 16, if the data length is larger or less than the element number of the data table accessed, error code 4 occurs. It means the data length for function code 16 should be strictly the same as the size of the accessed data table. If the data written to the power monitor by using function code 16 is outside of the legal range as shown in Appendix A, error code 5 occurs.
Chapter 4 Communication DeviceNet Communication Option The Powermonitor 3000 units with optional DeviceNet communication operate as a slave device on a DeviceNet network. It serves data to a DeviceNet master station such as a PLC-5 or SLC 500 DeviceNet scanner module, a ControlLogix DeviceNet bridge module, a PanelView operator terminal and RSLinx direct and pass-thru DeviceNet drivers.
Communication Chapter 4 Polled I/O messaging can automatically provide fresh data at update rates as fast as 100 ms. The power monitor supports both Every Scan and Background polled messaging. You select the poll type and polling rate by using RSNetworx for DeviceNet software. • Every Scan: Polls the power monitor once per scan. Set the Interscan Delay to at least 100 ms. An Interscan Delay of less than 100 ms slows the power monitor’s delivery of metering information.
Chapter 4 Communication Please contact Rockwell Automation technical support if you find that the default settings do not result in adequate network performance. Explicit Messaging Use explicit messaging to read and write all data tables other than the I/O messaging table. The specific details of explicit messaging depend upon the master device that initiates the message. The example in this section uses an Allen-Bradley SLC 500 controller and DeviceNet Scanner (1747-SDN) as the master.
Communication Chapter 4 Word 0 contains a transmit identifier (TXID) and command byte. Assign each explicit message a unique TXID in the range of 0…255 decimal (0 to FF hex). The TXID is used to identify the response to this message request. These are valid command codes: • 1 hex = Execute transaction block. Use this command first to start the explicit message. • 4 hex = Delete transaction from response queue.
Chapter 4 Communication Once the message is assembled, your ladder program transfers the integer file to the scanner module M0 file starting at word 224 (SLC 500 controller) or block transfers the 64-word integer file to the scanner module (PLC-5 controller). The ControlLogix controller includes in its instruction set a CIP Generic message instruction that builds the transaction header and path from information you enter into the message setup dialog in RSLogix 5000 software.
Communication Chapter 4 DeviceNet Message Types The power monitor supports the following DeviceNet message types.
Chapter 4 Communication DeviceNet Class Services As a group 2 slave device, the power monitor supports the following class and instance services. DeviceNet Class Services Service Name Service Code (hex) Service Code (decimal) Reset 05 05 Get_Attribute_Single 0E 14 Set_Attribute_Single 10 16 Allocate_Group_2_Identifier_Set 4B 75 Release_Group_2_Identifier_Set 4C 76 DeviceNet Object Classes The power monitor supports the following DeviceNet object classes.
Communication Chapter 4 DeviceNet Unique Write Identifier The communication interface used in the DeviceNet communication option is programmed to reject duplicate write messages. Because of this, all writeable data tables in the power monitor include an element called DeviceNet unique write identifier. In many cases, your client application may ignore this element because the message data is unique.
Chapter 4 Communication Protocol Selection Table Protocol RSLinx Connection Type Pure CSP Client Compatibility(1) RSEnergyMetrix and RSPower Compatibility Logix and MicroLogix Compatibility Implicit Messaging Compatibility CIP (default) EtherNet/IP No Yes Yes Yes CSP DF1 (CSP) Yes No No No CIP/CSP DF1 (CSP) Yes No Yes Yes In addition to the selectable protocols listed above, the Ethernet port supports Modbus TCP beginning with Master Module firmware version 4 and Ethernet firmware
Communication Chapter 4 Ethernet PCCC/CSP protocol You may set up messaging from legacy controllers such as PLC-5 and SLC 500 controllers, to a power monitor with optional Ethernet communication, by using peer-to-peer message instructions. In the message setup, specify the controller data table address, size of the data in elements and the channel the message instruction is to use. For the target device (power monitor), specify its IP address and data table address.
Chapter 4 Communication EtherNet/IP (CIP) Protocol Allen-Bradley controllers since the release of the ControlLogix platform have used the EtherNet/IP or CIP protocol. In particular, PLC-5 and SLC 5/05 controllers at or later than the following series and revision levels support CIP communication: • • • • • PLC-5/xxE Series C/ Rev. N PLC-5/xxE Series D/ Rev. E PLC-5/xxE Series E/ Rev.
Communication Chapter 4 When you select Yes in the MultiHop field, the MultiHop tab appears in the dialog. Enter the IP address of the power monitor in the 1756-ENET I. P. field (192.168.4.49 is used here as an example) and any integer in the 1756 backplane Slot field. PLC-5/xxE Controller MultiHop Configuration The example below shows the MultiHop configuration for messaging from a PLC-5/xxC ControlNet processor through a ControlLogix Gateway to an Ethernet power monitor.
Chapter 4 Communication Set up the Communication tab in the ControlLogix message instruction the same for each messaging type. ControlLogix Controller to Powermonitor 3000 Unit Communication Tab Example The first example below reads the Voltage and Current table from a power monitor into the ControlLogix controller tag dataPM3K_VI(0) by using a PLC-5 Typed Read, configured as an array of 14 elements of type Real. You would configure a CIP Data Table Read the same way except for the message type.
Communication Chapter 4 The next example shows the message configuration for a CIP Generic message type. A CIP Generic message can read or write data, depending on the Service Type you specify. Refer to DeviceNet Class Services on page 102. In this example, the ControlLogix reads the User-configured Data Table into tag dataPM3K_User(0), configured as an array of 23 elements of Real type.
Chapter 4 Communication Set EtherNet/IP I/O Connection Ethernet Powermonitor 3000 units support a Class 1 connection to Instance 1 and 2. 1. To utilize this scheduled connection to a ControlLogix controller, open the controller program offline in RSLogix 5000 software. 2. Select the 1756-ENET/B or 1756-ENBT/A module in the I/O configuration. 3. Add the power monitor as a Generic Ethernet Module. I/O Connection Setup shows a typical configuration.

Chapter 4 Communication Controller Tags 9. Download the revised program to the controller. 10. Run RSNetworx for ControlNet software to schedule the connection between the controller and the power monitor. Refer to the RSNetWorx for ControlNet documentation for assistance. The ControlNet power monitor supports up to 64 concurrent Class 1 connections to instance 1 and one concurrent connection to instance 2.
Communication Chapter 4 Communicating to a Powermonitor 3000 Unit from an SLC Controller through 1747-KFC15 ControlNet Module Connect the 1747-KFC15 module according to your instruction manual documentation. There should be a connection from the KFC15 RS232 port to Channel 0 of the SLC controller.
Chapter 4 Communication 2. Fill out the Setup dialog as shown. Notice that under target device that power monitor data table N11 (Date and Time) was selected. The Local Node Address is the address of the power monitor Controlnet Node Address 4. Writing Files to the Power Monitor Writing data to the power monitor is done with the same method. It is recommended that 1 integer file and 1 float file be set aside in the SLC controller for use when writing to the power monitor.
Communication Chapter 4 2. Fill out the Setup dialog as shown. Notice that under target device that power monitor data table F10 (Basic Configuration) was selected. The Local Node Address is the address of the power monitor Controlnet Node Address 4. The information to write was loaded into file F12:0 of the SLC controller and is 9 elements long.
Chapter 4 Communication Create a PLC-5 Typed Read You can message integer and float files to and from the power monitor using PLC-5 typed message instructions by using the following steps. Insert a MSG Instruction to the ladder rung and assign a control. This example reads the Voltage, Current and Frequency table, File F15 from the power monitor. Notice that when using an unscheduled message directly to the power monitor, in this case node 4, that the message format is local, multi-hop selection is no.
Communication Chapter 4 Create a PLC-5 Typed Writes The following selection performs a write operation to the basic configuration table F10 of the power monitor. Insert a MSG Instruction to the ladder rung and assign a control. This example writes configuration to the Basic Configuration table, File F10 in the power monitor. This message transfers 9 floats from table F8:0 to the power monitor table F10. The power monitor address is at node 4, local message.
Chapter 4 Communication How to Clear or Preset Energy Counters by Using Communication You may clear or preset the energy counters by performing a table write to the Metering Real and Apparent Energy Results table or the Metering Reactive Energy and Amp-hour Results table. These read/write tables each contain 23 integer elements. • Password: required to clear or preset an energy counter, returns -1 • Parameter select: bitfield used to select parameter for clearing or presetting See below.
Communication Chapter 4 User-configured Data Table If your application requires monitoring a small number of parameters normally found in different data tables, and you need to conserve communication bandwidth, then the power monitor user-configured data table may be an ideal solution. To use this table, your data client application performs a write to the User-configured Table Setup table, containing the desired parameters that you select from the Parameters for Trend Log and Configurable Table.
Chapter 4 Communication User-configured I/O Table You may configure Input Messaging Instance 1 in Powermonitor 3000 units with optional DeviceNet, EtherNet/IP, or ControlNet communication in the same way as the user-configured data table above. You have one additional option for Instance 1: you may select the data type of Instance 1 as integer (0) or floating-point (1). If you change the configuration of Instance 1, an existing Class 1 connection will fault.
Chapter 5 Setpoint Programming and Operation Setpoint operation provides a method other than communication for the power monitor to be used in and interact with power and energy applications.
Chapter 5 Setpoint Programming and Operation TIP If more than one setpoint is used to control the relay and/or KYZ output, the individual setpoints are evaluated in a logical and to determine the output state. You may read setpoint output flags in the Discrete Data table on page 193 and the Remote I/O, DeviceNet, EtherNet/IP and ControlNet I/O Messaging Parameters on page 191. You may read only the first 8 setpoint output flags in the discrete input table with optional remote I/O communication.
Setpoint Programming and Operation Chapter 5 Over Reverse Setpoint An over reverse setpoint is the mirror image of an over forward setpoint. For reverse setpoints, all the magnitudes and limits are negative. An over reverse setpoint activates when the magnitude of the parameter being monitored (defined by the Setpoint Type) increases beyond the Setpoint High Limit in the negative direction and remains over the limit for a time greater than the Setpoint Action Delay.
Chapter 5 Setpoint Programming and Operation Under Forward Setpoint An under forward setpoint is similar to an over forward setpoint, except the Setpoint High Limit and the Setpoint Low Limit are reversed. An under forward setpoint activates when the magnitude of the parameter being monitored (defined by the Setpoint Type) decreases below the Setpoint Low Limit and remains below the limit for a time greater than the Setpoint Action Delay.
Setpoint Programming and Operation Chapter 5 Under Reverse Setpoint An under reverse setpoint is the mirror image of an under forward setpoint. The magnitude and all limits are negative numbers. An under reverse setpoint activates when the magnitude of the parameter being monitored (defined by the Setpoint Type) decreases below the Setpoint Low Limit in the negative direction and remains below the limit for a time greater than the Setpoint Action Delay.
Chapter 5 Setpoint Programming and Operation Not Equal Setpoint A not equal setpoint is the opposite of an equal setpoint, activating when monitored parameter does not equal the Setpoint High Limit for a time greater than the Setpoint Action Delay. It releases when the monitored parameter equals the Setpoint High Limit for a period of time greater than the Setpoint Release Delay.
Setpoint Programming and Operation Chapter 5 Setpoint Configuration Parameter Name Parameter Description Range Units Default Setpoint Low Limit The value being used as a reference to deactivate the setpoint for over comparisons, or to activate the setpoint for under comparisons. 0…10,000,000 Depends on type 0 Setpoint Action Delay The minimum time in seconds that the setpoint limit must be exceeded continuously before the setpoint will trigger. 0…3600 Sec (M4, M5) 0 0…30,000 0.

Setpoint Programming and Operation Chapter 5 Reading Setpoint Status Data by Using Communication To read the setpoint status by using communication, the client uses the indexed read method. The power monitor uses the Setpoint Setup/Read-back Select and Status table both to select the setpoint to be read on the next read, and to return the status of the selected setpoint. In auto-increment mode (0), the first read returns the status of setpoint 1, the second read setpoint 2, and so on.
Chapter 5 136 Setpoint Programming and Operation Publication 1404-UM001F-EN-P - November 2009
Chapter 6 I/O Operations The power monitor is equipped with two relay outputs and two status inputs designed to provide a discrete interface with your application. Relay and KYZ Output Operations The Relay output is an electromechanical Form C relay with contacts rated at 10 amperes at 240V ac or 250V dc. This set of contacts is also rated to meet IEEE C37.90 requirements for power circuit breaker tripping duty.
Chapter 6 I/O Operations Pulsed Control Many electric energy meters provide a dry contact output that changes state at intervals determined by a metered parameter. Pulsed control lets the power monitor emulate this function. You may select the following options for the Control source parameter: 1 2 3 4 5 6 = = = = = = Watt-hours forward Watt-hours reverse VAR-hours forward VAR-hours reverse VA-hours Ampere-hours Set the Output width to the desired pulse duration in milliseconds.
I/O Operations Chapter 6 3. Select a maximum pulse rate. This should be between 2 and 5 pulses per second for a two-wire KYZ connection and between 2 and 10 pulses per second for a three-wire connection. Let’s use a three-wire KYZ connection and a pulse rate of 4 pps. 4. Compute the output scale by dividing the result of step 2 by the result of step 3 and rounding to the nearest integer. For our example, we’ll set the output scale to 70.
Chapter 6 I/O Operations No Control Operation You may also select no output control by selecting a value of zero (0) for the Control source parameter. This mode enables only output forcing. Communication Loss Behavior IMPORTANT The relay output contacts and solid-state KYZ output contacts on the power monitor may be used to control other devices through setpoint control or communication. You configure the response of these outputs to a communication failure.
I/O Operations Status Input Operations Chapter 6 The power monitor’s two self-powered status inputs provide a number of flexible configuration options that help customize the power monitor operation to meet the requirements of your specific application. Counters You may use the power monitor to monitor discrete events such as circuit breaker status or kWh pulses from a legacy electrical energy, steam, gas or other type of meter.
Chapter 6 I/O Operations Event Logging of Status Inputs You may choose whether or not to record status input transitions in the Event Log. If you were using a status input to read a KYZ meter pulse, for example, recording transitions into the Event Log would quickly fill the log and overwrite potentially important event information. On the other hand, you may use the status input to detect a discrete condition that you want logged. Refer to Event Log Configuration Options on page 144.
Chapter 7 Data Logging Its inherent data logging capability makes the power monitor a versatile component in a number of power and energy applications. Cost allocation applications can read billing variables like energy usage and demand from the configurable Trend Log, making the accuracy of reports less dependent on a continuous network connection.
Chapter 7 Data Logging Event Log Configuration Options There are two options in the Event Log setup. • You may choose to log or ignore (ignore is default) status input change-of-state. • You may choose to log or ignore (log is default) changes to the date and time setting. These choices provide you with the flexibility to ignore routine occurrences, thereby increasing the time that important events are stored. For example, a status input may count pulses from a water or gas meter.

Data Logging Chapter 7 Reading Data from the Event Log by Using Communication The Event Log uses the indexed read method. The Event Log Configuration/Read-back Record Select table is the Read-back Select table and the Event Log Results table is the Results table. You may select among a number of read-back options for the Event Log.
Chapter 7 Data Logging TIP The power monitor expresses timestamps in an array of four data table elements: Year Month/day Hour/minute Second/hundredth of a second Each timestamp parameter (except the Year) is a combination of its first and second element. For instance, the Month = the parameter value divided by 100 with the remainder = the Day. Example: 1230 = December 30th.
Data Logging TIP Chapter 7 If you use the power monitor with RSEnergyMetrix energy logging software, you should coordinate the parameters selected for the Trend Log with those logged by the software. This allows for the energy logging software to poll the Trend Log data, allowing for automatic data repopulation of the energy database. Calculating Trend Log Depth How long the Trend Log takes to fill may be as little as 90 minutes or as long as 2 years depending on how you configure the log.
Chapter 7 Data Logging Parameters per Record Formula If your application requires a certain number of records or time to preserve logged information, this formula returns the number of parameters per record allowed. ⎛ ⎞ ⎜ ⎟ 16384 P = INT ⎜ -------------------------------- – 5.5⎟ ⎜ ⎟ ⎛ D -⎞ ⎝ CEIL ⎝ ----------⎠ 7 – F⎠ Where: CEIL (x) = the smallest integer greater than x. EXAMPLE For example, CEIL (1914.28) = 1915.
Data Logging Chapter 7 Example 2: Another user wants to log several parameters every 5 minutes indefinitely, retrieving the records within one week after the end of each month. He saves the retrieved data and creates trend graphs on his PC. The question is how many parameters may be monitored. The Parameters per Record Formula applies to this example.
Chapter 7 Data Logging TIP Although you may configure up to 16 Trend Log parameters on units with optional DeviceNet communication, the results table will return only the first 8. The power monitor clears the trend log when you change any parameter or the logging interval. You may perform a simple table read of the Trend Log Configuration/Read-back Record Select table to view the existing Trend Log configuration.
Data Logging Chapter 7 Only mode 0, 1, and 2 are supported by DF1 and remote I/O communication. In modes 0, 1, and 2 the client need only read the results table repeatedly until the entire Trend Log is read. In modes 3…6 the client must alternate writes to select the next read-back record with reads of the results table. You may obtain the number of records in the Trend Log by reading the Trend Log Configuration/Read-back Record Select table, elements 7 and 8.
Chapter 7 Data Logging Accessing the Min/Max Log by Using the Display Module You may view, enable, disable, or clear the min/max log by using the display module. Interfacing with the Min/Max Log by Using Communication Write Min/max Log configuration settings and command by using a table write to the Min/Max Log Configuration/Read-back Select table. Access data in the Min/max Log by using the indexed read method.
Data Logging Chapter 7 Min/Max Log Parameter Listing Param.
Chapter 7 Data Logging The Min/Max Log Results table is a read-only data table consisting of 11 floating-point elements containing the following information: • Parameter #: See the Min/Max Log Parameter Listing table above • Min and max values • Timestamps: for Min and Max values in four-element timestamp format Time-of-use The power monitor provides a Time-of-Use Log. Also called the TOU log, it provides a one-year time-of-use history of energy usage and demand.

Chapter 8 Advanced Features In this chapter we discuss major features that, for the most part, are found only in the Powermonitor 3000 M6 and M8 models. The exception is that basic harmonic analysis is supported in the M4 and M5 models. Oscillography Oscillography captures waveforms of the voltage and current present at the power monitor input terminals. A client application reads oscillography records by using the indexed read method.
Chapter 8 Advanced Features Configuring Oscillography You may configure oscillography only via communication. The display module does not support an interface to oscillography. Configure oscillography by performing a table write to the Oscillograph Configuration/Read-back Data Select. This read/write table of 11 integer elements comprises the following configuration and command parameters. • Password: needed to configure the capture type or pre-trigger, or execute a command to trigger or clear a capture.
Advanced Features Chapter 8 • Capture clear status: Read-only bitfield that indicates which capture numbers are clear. Bit 0 (LSB) corresponds to capture 1, bit 1 to capture 2 and so on. For each bit, 1 indicates clear, 0 indicates not clear. • Capture ready status: read-only bitfield that indicates which capture numbers contain captures that are ready to read. Same bit correspondence as above. For each bit, 1 indicates the capture is ready, 0 indicates no capture or not yet ready.
Chapter 8 Advanced Features Read-back Mode The data client uses the indexed read method to read oscillogram capture data. The readback mode options include the following: • Auto-increment all channels: successive reads of the Oscillograph Results table increment through all remaining blocks of the current channel, increment through all remaining channels and wrap back to the original channel.
Advanced Features Chapter 8 The data client sets up the read-back configuration with a table write to the Oscillograph Configuration/Read-back Data Select table, the content of which is described above. As with other indexed reads, DeviceNet and Ethernet optional communication support only manual increment read-back mode so that the client must write a read-back select message before each read of the results table.
Chapter 8 Advanced Features Each data point is expressed in calibrated analog-to-digital (A/D) converter counts with a resolution of 8192 (13-bit w/sign) or 128 (7-bit w/sign). A client may calculate the primary-side instantaneous voltage or current magnitude of each data point by using the following formula: M ( max rms ) • 2 M i = -------------------------------------- • N t • M data R max Where: • Mi = instantaneous value of the voltage or current data point • M(max rms) = max rms magnitude = 399.
Advanced Features Chapter 8 Trigger Statistics The trigger source and capture identifier are combined in one element, and indicate what triggered the capture and a unique capture identifier or serial number. The value divided by 1000 gives the trigger source: 0 = none; 1…20 = setpoint number; 21 = native communication; 22 = optional communication. The remainder of this calculation is the unique capture identifier which increments by 1 from 0…999 and rolls back to 0.
Chapter 8 Advanced Features Harmonic Analysis The power monitor provides harmonic data to help you understand this important element of power quality in your facility. Each model provides a different level of harmonic information. The Harmonic Analysis Functionality table provides an overview of the harmonic analysis available in each model. You may access all harmonic data by using communication. The display module can access average values of the parameters as indicated in the DM column.
Advanced Features Chapter 8 The standard IEC definition of harmonic distortion is the Distortion Index (DIN) and is computed for each channel as follows: ∞ DIN = Σ ( H )2 n Σ ( H )2 n n = 2 -------------------∞ n = 1 Where: • Hn = magnitude of the nth harmonic (n ≤41 or 63) • DIN is equivalent to IEC THD Crest Factor This is another quantity that is sometimes used to describe the amount of distortion present in a waveform. It can also be used to express the dynamic range of a measurement device.
Chapter 8 Advanced Features TIF Another method of measuring signal distortion is the Telephone Influence Factor, sometimes called the Telephone Interference Factor. This measurement is used to estimate the effect that the power line harmonics have on nearby analog telephone conductors. This method weighs each of the harmonics based on the physiological and audiological characteristics of the human ear.
Advanced Features Chapter 8 K-Factor K-Factor measures additional heating in a power transformer due to the harmonics in the power signal. These harmonics cause additional heating due to increased core losses that occur at higher frequencies. The increased losses are related to the square of the harmonic frequency. Therefore, a slight harmonic content can significantly increase the heat rise in a power transformer.
Chapter 8 Advanced Features IEEE-519 TDD and IEEE-519 Pass/Fail IEEE-519 is the IEEE standard for Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems. The 1404-M6 refers to the 1992 version of this standard. IEEE-519 provides recommended limits for the level of harmonic current injection at the Point of Common Coupling (PCC) between the utility and your setup.
Advanced Features Chapter 8 Harmonic Distortion The power monitor calculates the magnitude of each individual harmonic with respect to the fundamental. Results are calculated for harmonics 1…41 (M6) or 1…63 (M8) for all 7 voltage and current channels. Each result is expressed as a percentage of the fundamental. Configuring Harmonic Analysis You may configure harmonic analysis only via communication. The display module does not support harmonic analysis configuration.
Chapter 8 Advanced Features Readback Mode The data client uses the indexed read method to read harmonic analysis and individual harmonic data. The options include the following: • Auto-increment (0): increments the channel after each read of the Harmonic Results; THD, Crest Factor, and More table. This also controls the read-back channel for individual harmonics results tables.
Advanced Features Chapter 8 • TIF: Telephone influence factor. Range 0.0…999.9*1022 • K-factor: Range 0.0…999.9*1022 • IEEE-519 TDD: Total demand distortion. Range 0.0…999.
Chapter 8 Advanced Features In the Harmonic Results; Odd Harmonics 23…41, Harmonic Results; Even Harmonics 2…20 and Harmonic Results; Even Harmonics 22…40 tables the first nth harmonic element is reserved and returns a value of 0. Sag and Swell The Powermonitor 3000 M6 and M8 models are capable of detecting voltage sags and swells. There are many definitions for sag and swell. IEEE 11591 defines sag as: a decrease to between 0.1…0.9 pu in rms voltage or current at the power frequency for durations of 0.
Advanced Features Chapter 8 Setpoint #19 is setup to detect voltage sag and has the following configuration data: • • • • • • • Type = Voltage Sag Evaluation condition = Under forward High Limit = 90% Nominal System Voltage Low Limit = 90% Nominal System Voltage Action delay = 0 Release delay = 0 Output action = Capture oscillograph Setpoint #20 is setup to detect voltage swell and has the following configuration data: • • • • • • • Type = Voltage Swell Evaluation condition = Over forward High Limit =
Chapter 8 Advanced Features 3. Periodically check the event log or capture ready status for an indication that a sag or swell has occurred. 4. Read the event log to get the timestamp, duration of the disturbance, the worst case magnitude, and the identifier of the capture. 5. Find the capture that has the same identifier as the one found in the event log record by reading the first block from each capture location. Read the entire capture from the power monitor.
Advanced Features Load Factor Chapter 8 The Powermonitor 3000 M6 and M8 models provide a Load Factor Log which calculates and stores a group of plant demand metrics that indicates how stable (or, conversely, how dynamic) a load is over a period of time, usually one month. Use communication to configure load factor operation and read the results. The display module does not support an interface to the load factor log. Load factor is the average demand divided by the peak demand for the month.
Chapter 8 Advanced Features Reading the Load Factor Log To select the Read-back mode or record, an auto reset/store day of the month, or issuing a manual reset/store command, perform a table write to the Load Factor Log Configuration/Read-back Select table. Load factor log data is not available via Modbus communication. This read/write table contains six integer elements as follow: • Password: required for changing the auto clear/reset day or manual clear/reset command.
Advanced Features Chapter 8 • Average demand current: expressed in VARs. Range 0.0…999.9*1021 • Load factor current: expressed in per cent. Range 0.0…100.0 • Elapsed time: hours that have elapsed since the last automatic or manual clear/reset operation • Ending date: for this load factor record. Range 0…123199 (mmddyy).
Chapter 8 Advanced Features Transient Capture Transient Analysis Configuration Perform a table write to the Transient Analysis Configuration/Read-back Select to configure transient analysis. This read/write table of 13 floating-point elements contains the following configuration, command and read-back select parameters: • Password: required for configuration and command. Use a valid password or -1 for read-back select.
Advanced Features Chapter 8 • Auto-threshold set margin: range 1.0…100.0 per cent, default 20.0 • Voltage trigger threshold: range 0.1…1000.0, default 10.0 • Current trigger threshold: range 0.1…1000.0, default 10.0 Threshold Configuration The power monitor compares voltage or current transients against a threshold that you may set manually or command to be set automatically. You select either voltage channels or current channels with the Detection mode parameter.
Chapter 8 Advanced Features • Voltage: three RMS voltage results that express line-to-line (delta wiring modes) or line-to-neutral (all other wiring modes) for the current Cycle number. Range 0.0…999.0 * 1021 • Current: four RMS current results (L1, L2, L3, L4) for the current Cycle number. Range 0.0…999.0 * 1021 • Trigger channel: indicates which channel caused the transient capture. 1=V1, 2=I1, 3=V2, 4=I2, 5=V3, 6=I3, 7=I4 • Index at trigger: the value of the transient index at the time of the capture.
Advanced Features Chapter 8 • Capture clear status: Read-only bitfield that indicates which capture numbers are clear. Bit 0 (LSB) corresponds to capture 1, bit 1 to capture 2 and so on. For each bit, 1 indicates clear, 0 indicates not clear. • Capture ready status: read-only bitfield that indicates which capture numbers contain captures that are ready to read. Same bit correspondence as above. For each bit, 1 indicates the capture is ready, 0 indicates no capture or not yet ready.
Chapter 8 Advanced Features The Transient Capture Results table comprises the transient capture results. This read-only table comprises these 29 (DeviceNet network) or 59 (all other communication options) integer elements: • Capture timestamp: in three elements using the standard timestamp format except the year is omitted • Capture number: in the range 1…6 • Channel number: in the range 1…7 (1=V1, 2=I1, 3=V2, 4=I2, 5=V3, 6=I3, 7=I4) • Block number: block number of the data contained in the table.
Advanced Features Chapter 8 For example, consider the following capture: • • • • • PT primary = 13.8 kV PT secondary = 120V CT primary = 100 A CT secondary = 5 A Delta voltage mode (line-to-line) You would multiply each data point by the following factor to correctly display the waveform: Factor = ( 691.1 • 1.414 ) ⁄ 8192 • ( 13800 ⁄ 120 ) = 13.72 Capture Statistics The Capture timestamp and Capture identifier are important statistics that identify the capture.

Appendix C Sample Applications Introduction This appendix contains sample applications including ladder diagrams to help you get started in setting up communication between your application and a power monitor. The application samples depict basic methods for reading and writing data between a power monitor and your programmable controller or other application. Expand on these basic steps to customize your application to meet your business needs.
Appendix C Sample Applications System Clock Sample Applications The power monitor system clock (date and time) is an ideal sample application for these reasons: • It is important to set the system clock so that data log records or oscillograms are recorded with accurate time stamps. • It is easy to see if your application has successfully written and read the system clock.
Sample Applications Appendix C Data Tables In the SLC 500 data tables, table N111 is the destination table for the Read message and N211 is the source for the Write message. Table N211 contains the following values for setting the date and time in a power monitor with a password of 0 to January 1, 2003 at 12:00 midnight.
Appendix C Sample Applications Ladder Diagram 284 Publication 1404-UM001F-EN-P - November 2009
Sample Applications Appendix C Message Setup Dialogs Read Message Dialog Write Message Setup PLC-5 Controller by Using Remote I/O The second example also reads and writes the power monitor date and time but uses a PLC-5 controller and remote I/O. In this example, a power monitor has a logical address of Rack 1, Group 0. The PLC-5 data table files used are the same as in the previous example.
Appendix C Sample Applications The source and destination data tables in the PLC-5 must contain at least as many words as the block transfer length. The Read Clock from PM3K and Set Clock from PLC bits are used to initiate the messages, and are reset when the message instruction either completes successfully or an error occurs.
Sample Applications Appendix C EtherNet/IP and ControlLogix Networks The third example reads and writes the power monitor date and time data table by using a ControlLogix controller and an EtherNet/IP communication network. Tags The example uses two ControlLogix tags, PM3K_Date_Time and Set_date_time. Both are arrays of 8 INT elements. The program also uses two standard MESSAGE tags, Read_time and Set_time.

Appendix C Sample Applications Message Setup Dialogs Read Message Dialog The communication tab of the message setup simply shows the module name in the I/O configuration for this example. Communication Tab The write message dialog is similar to the Read.
Sample Applications Appendix C Write Message Dialog Note that the source length is in Bytes, not elements. Since this message write 8 INT elements, the message length is 16 bytes. RSLinx DDE/OPC and Microsoft Excel Software You may create a simple data transfer application by using RSLinx direct data exchange (DDE) capabilities and a DDE client such as Microsoft Excel software. This example uses DDE to read and write the value of the real-time clock in a power monitor.
Appendix C Sample Applications 3. Click New and enter a name for the DDE/OPC topic. The example uses DF1_1404_123.
Sample Applications Appendix C 4. Browse through the tree in the Data Source dialog to locate your power monitor and click its icon to select it. 5. Click the Data Collection tab, select SLC 5/03+ as the Processor Type, leaving the rest of the settings as default.
Appendix C Sample Applications 6. Click Apply and confirm when prompted. 7. Click the Advanced Communication tab to verify the driver and path settings in the topic and click Done. The Microsoft Excel Sample Worksheet The sample worksheet uses Visual Basic for Applications (VBA) macros to read and set the date and time in the power monitor.
Sample Applications Appendix C The range Sheet1!D7:D14 is the write source range and the read target range. The Read graphic element is associated with the following VBA script or macro. Sub ReadDateAndTime() 'Open DDE link; the first argument is the application we 'want to DDE with.
Appendix C Sample Applications IMPORTANT If you are using RSLinx Classic software as your OPC software, a licensed RSLinx OEM or higher version is required. MicroLogix Controller and EtherNet/IP Communication Networks This example reads and writes the power monitor date and time table by using a MicroLogix 1400 controller and EtherNet/IP communication. IMPORTANT The power monitor master module firmware must be 4.
Sample Applications Appendix C Data Tables The MicroLogix 1400 data table N111 is the destination table for the Read message and N211 is the source for the Write message. Table N211 contains the following values for setting the date and time in a power monitor with a password of 0 to January 1, 2003 at 12:00 midnight.
Appendix C Sample Applications The Read Clock from the Powermonitor 3000 unit and Set Clock from the MicroLogix 1400 controller bits are used to initiate the messages, and are reset when the message instruction either completes successfully or an error occurs. In your application code, if the message rungs are controlled programmatically, be sure that only one message is enabled at a time.

Sample Applications Appendix C Message Configuration: Read Modbus Date and Time table registers: 40101-40108, length 8 elements.
Appendix C Sample Applications Message Configuration: Write Date and Time Summary You may use the examples above as building blocks to create applications to meet your business needs. Refer to Appendix A for detailed information on the power monitor data tables as well as the sections of this manual that describe the functionality you wish to include in your application.
Sample Applications Multiple Data Table Reads by Using DeviceNet Appendix C The following is a ladder program designed to return a number of real-time data tables from a power monitor to an SLC 500 processor via DeviceNet by using a DeviceNet scanner module.
Appendix C Sample Applications A command byte of 1 is used first to start the explicit message. After a response has been received from the scanner, a command byte of 4 is used to remove this transaction from the scanner. If the command byte of 4 is not written to the SLC 500 DeviceNet Scanner, then it does not process further transactions. Word M0:1.224 TXID Cmd TXID x 256 + Cmd 20 x 256 + 1 5121 Word M0:1.225 A port number and transaction body size is needed for this word.
Sample Applications Appendix C The MAC ID is the node number of the device that the DeviceNet scanner is communicating to; this example uses node 5. Word M0:1.226 Service MAC ID Service x 256 + 14 x 256 + MAC ID 5 3589 Word M0:1.227 The class number is the first word of the transaction body; class 4 is used to retrieve the real-time data assemblies. Word M0:1.227 Class 4 Word M0:1.
Appendix C Sample Applications SLC 500 Sequencer Operation This example uses a sequencer instruction and indirect addressing to optimize program operation. During initialization of Run mode, the sequencer input file is loaded with the numbers corresponding to the two explicit message transfers to be performed. Once Run mode has begun, the ladder program remains in this mode.
Sample Applications Appendix C The reset word for the sequencer is N10:0. The first word in the rotation of the sequencer is N10:1. The value in N10:0 must be the same as that in N10:1. The size of file N10 is equal to the size of the largest sequencer input file. This size depends on the number of explicit message transfers to be performed. The sequencer length may be expanded or reduced for Run mode.

Appendix C Sample Applications Ladder Diagram Sample logic program that shows a way to configure a Powermonitor 3000 User Configurable Data Table from a ControlLogix controller via the 1404-NENET communications option card using EtherNet/IP. See the accompanying text for a list of tags to be created in the ControlLogix controller. The first rung allows a selection of tables to write to the PM3000.
Sample Applications Appendix C The message configuration for the ReadOld message is shown below. This rung inserts a brief time delay before enabling the WriteNew message instruction. Start msgReadOld.DN TON 1 EN Timer On Delay Timer Preset Accum DN Timer1 100 0 After clearing the flags from the previous write, this rung performs a data table write to transfer the selected user configured data table setup to the Powermonitor 3000 unit.
Appendix C Sample Applications The message configuration for writing the new configuration table to the power monitor is shown below.
Sample Applications Appendix C Timer2 delays evaluating the write status until the Powermonitor 3000 unit has reset. This rung evaluates the results of writing the new configuration. The "Failed" flag asserts if the WriteNew message instruction errors-out, or if the GetStatus instruction errors out twice, or if the write status indicates bad data in the download table.
Appendix C Sample Applications The message configuration for the GetStatus message is shown below. Communicating with a SLC 5/05 (1747-L552) Controller and ControlNet Scanner (1747-SCNR), Unscheduled Messaging The Power Energy and Management Systems development team tested the following example ladder. The scan times for execution of the ladder are as follows.
Sample Applications Appendix C N7 SCNR_FILE The following items are of importance in file N7:0. File N7:0 Bit # Importance N7:0 Read/Write N7:0/15 EN - Written to by the ladder to enable communication transaction.
Appendix C Sample Applications N9 CIP Word # Description of Function N9:6 Targets Instance number to read or write. N9:7 Target Attribute. Power monitor Attribute of assembly instance is 3. (3) N9:8 Target member number. (Not used) N9:9 Size of the data in words. Used for writes only. When performing a read operation this parameter is forced to 0. Size of Power monitor tables is type N = elements x 1, type F = elements x 2. N9:10 Not used by CIP_SETUP. N9:11 Enables a read/write operation.
Sample Applications Appendix C Writing Information through the SCNR Scanner Observe the sample of the CIP_SETUP file for the writing the configuration of the basic configuration table Instance 4 of the power monitor. CIP Setup File TIP The write procedure differs slightly from the read process. N9:4 service has been changed to 0x10 or 16 decimal (Set Single Attribute). N9:6 is the write instance assembly number of the power monitor basic configuration table.
Appendix C Sample Applications Power Monitor Ladder Example for SLC Scanner Module through SCNR Power Monitor with SLC Scanner Module While message is pending bring back the CIP message control status. Message Pending B3:0 COP Copy File Source #M0:3.1000 Dest #N7:0 Length 10 0000 0 After setting up N9 CIP_SETUP file, turn on bit N9:11/1 to start the read transfer from the power monitor. This process clears out the first 9 words of N7:0 CIP message file.
Sample Applications Appendix C When a write of a float file is being performed it is necessary to swap the words in teh float file before sending the write request. This is only necessary for Instance 4 or Instance 52. Allow Write N9:11 EQU Equal Source A 0002 0 Source B EQU Equal Source A Source B N9:6 8< 4 4< JSR Jump To Subroutine SBR File Number U:4 N9:6 8< 52 52< Allow the scanner to write to the power monitor. Put the new integer configuration data in N14 starting at location 0.
Appendix C Sample Applications This rung looks for the done bit with no errors. When the done bit is received the return information is tranfered and mainten ance is performed. Integer information can be read from file N10:0. Float information can be read from F8:0. The enable and done bit s are turned off and the bit N7:9 is latched to notify the user that the transfer was successful. Bit B3:0/1 is set to transfer any floats to the F8:0 file after swapping words from the incomming message.
Sample Applications Appendix C When an error or timeout occurs bit maintenance is performed to ready the ladder for the next message leaving the timeout or error bit set. Time Out Bit N7:0 0005 8 Message Pending B3:0 U 0 Perform Read N9:11 U 1 Error bit N7:0 12 Allow Write N9:11 U 0 Enable Transfer Bit N7:0 U 15 This calls the word swap routine and returns after the swapping has been completed.
Appendix C Sample Applications Perpare to swap words by copying source to N11 temp file. Initialize the word counter N12:0. 0000 COP Copy File Source Dest Length SBR Subroutine MOV Move Source Dest #N10:0 #N11:0 64 0 0< N12:0 30< Perform this task until all the words have been swapped.

Powermonitor 3000 units do not support this data type. connected load The total load which a customer can impose on the electrical system if everything was connected at one time. Connected loads can be measured in horsepower, watts or volt-amperes. Some rate schedules establish a minimum demand charge by imposing a fee per unit of connected load.
Glossary discrete input This is a Modbus mapped location used for reading bit length data. These bits typically reflect the value of the discrete inputs. Powermonitor 3000 units do not support this data type. exception reply This is the Reply Packet for a Modbus Command that was unsuccessful in operation. frequency The number of recurrences of a periodic phenomenon in a unit of time. In electrical terms, frequency is specified as so many Hertz (Hz) where one Hz equals one cycle per second.
Glossary initiator pulses Electrical impulses generated by pulse-initiator mechanisms installed in utility revenue meters. Each pulse indicates the consumption of a specific number of watts. These pulses can be used to measure energy consumption and demand. input register This is a Modbus mapped location used for reading word length data. For a power monitor slave device, the locations are defined by the Modbus Memory Map. lagging current The current flowing in an ac circuit which is mostly inductive.
Glossary ohm The unit of electrical resistance. One ohm is the value of resistance through which a potential difference of one volt will maintain a current flow of one ampere. peak demand The highest average load over a utility specified time interval during a billing period. If there is no ratchet clause in the rate schedule, then the peak demand is also the billing demand. polyphase Having or utilizing several phases.
Glossary ratchet clause A rate schedule clause which states that billing demand may be based on current month peak demand or on historical peak demand, depending on relative magnitude. Usually the historical period is the past eleven months, although it can be for the life of the contract. Billing demand is either the current month peak demand or some percentage (75% is typical) of the highest historical peak demand, depending on which is largest.
Glossary slave address This is the numerical label for slave devices. Valid slave device addresses are in the range of 0…247 decimal. The individual slave devices are assigned addresses in the range of 1…247. The value of 0 is reserved for broadcast. sliding demand interval A method of calculating average demand by averaging the average demand over several successive short time intervals, advancing one short time interval each time.
Glossary watt demand Power during a predetermined interval. The highest average, for example, Peak demand is commonly used for billing. watt hour (Whr) The number of watts used in one hour. Since the power usage varies, it is necessary to integrate this parameter over time. Power flow can be either forward or reverse. wattmeter An instrument for measuring the real power in an electric circuit. Its scale is usually graduated in watts, kilowatts, or megawatts.
