Powermonitor 3000 Operations 3-7 Power Factor Results The Powermonitor 3000 calculates true, displacement and distortion power factor, each on a per-phase and total 3-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.
3-8 Powermonitor 3000 Operations Table 3.4 Power and Power Factor Results Parameter Description Range Units Phase 1 Distortion Power Factor 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. 0 to 100 Percent The cosine of the phase angle between the fundamental voltage and current for an individual phase or all three phases; signed to show lead (+) or lag (-).
Powermonitor 3000 Operations 3-9 Configurable Energy Counter Rollover You may configure the number of digits at which energy values roll over to zero. The parameter range is 4 to 15 digits. Configure this setting in Advanced Device Configuration using the Display Module or by writing to Table A.6. This setting allows you to optimize the energy counter rollover for use with applications that support a limited number of significant digits.
3-10 Powermonitor 3000 Operations This method is known as thermal demand. You may set up a Powermonitor 3000 to determine its demand interval from the utility pulse. To accomplish this, connect the utility pulse to status input #2 and make the appropriate settings in the Advanced Device Configuration. If the utility does not provide a demand interval pulse, you won’t be able to synchronize with the utility to control your demand. In this case, you may use the sliding window method.

Chapter 4 Communications The communications features of the Powermonitor 3000 make it uniquely suited to integrate electric power usage information into your industrial control and information systems. Every Powermonitor 3000 is equipped with a native RS-485 communications port, and you can select optional communications that facilitate seamless integration with a variety of industrial networks.
4-2 Communications Native RS-485 Communications Your Powermonitor 3000 is set up to communicate via its native RS-485 port when you first power it up, except for units with an optional RS-232 communication port. The communications configuration includes the following parameters: • Protocol: Allen-Bradley DF1 half-duplex slave, Modbus RTU slave, or auto-sense. Default auto-sense • Data rate: Range 1200, 2400, 4800, 9600, 19,200 baud.
Communications 4-3 Table 4.
4-4 Communications • Flow Control: Enables or disables hardware handshaking. Default disabled • Inter-character timeout: Range 0 to 6553 msec. Default 0 (= 3.5 character times) To change your RS-232 port configuration, use the Display Module under the PROGRAM > OPTIONAL COMMUNICATIONS menu. The RS-232 communications standard supports point-to-point communications between 2 stations or nodes, with a maximum cable length of 15.24 meters (50.0 ft.).
Communications 4-5 Optional Remote I/O Communications Powermonitor 3000 units with a catalog number ending in “-RIO” are equipped with an optional Remote I/O port in addition to the native port. This dual-port option allows the use of both ports simultaneously. The port emulates a logical quarter-rack of I/O. You must configure the rack address, group number, baud rate and last rack status.
4-6 Communications Table 4.
Communications 4-7 enables remote baud rate selection. With this option selected, you may use RSNetworx for DeviceNet to set the Powermonitor 3000 baud rate.

4-16 Communications The Powermonitor 3000 is a read/write data server. It does not initiate data messages, but responds to messages from client devices. Its data is organized in data tables similar to those found in a SLC 5/03 programmable controller. Four primary methods to communicate with a Powermonitor 3000 are: • Table Writes - A client may write a table of data to the Powermonitor 3000. Only full data tables may be written.
Communications IMPORTANT 4-17 CSP file numbers are based on SLC 5/0x data table addressing. Because SLC 500 data tables 1 through 8 are assigned specific data types, file numbers lower than 9 are not used in the Powermonitor 3000. • For Remote I/O communications, a unique Block Transfer Size identifies the data table to read or write using a Block Transfer instruction.
4-18 Communications Expressing Data in Data Tables The Powermonitor 3000 may express metering data in several formats in the communications data tables. Floating-point data type is used to express most metering results. The trend log, min/max log and the user-defined data table also return values in floating-point format. The Powermonitor 3000 uses the IEEE 754, 32-bit floating-point format that is compatible with Allen-Bradley PLC-5 and SLC 500 controllers.
Communications 4-19 • Record identifier: The Powermonitor 3000 assigns event log records, oscillography and transient captures and other items unique identification numbers. These numbers typically begin at 0, increment by 1 each time a new record is created, and roll over to 0 once they reach their maximum value, typically 32,767. The data client may use the record identifier to associate records in different data tables or to ensure that subsequent reads contain fresh data.
4-20 Communications You may write data to the Powermonitor 3000 for basic and advanced device configuration, to set the time and date, to set up setpoints, logs, oscillography and transient analysis, and to select records to be read back from indexed data reads such as harmonics, oscillography and logs. Figure 4.1 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 ...
Communications 4-21 Simple Reads of Data Tables The following considerations apply to simple Powermonitor 3000 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 communications 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 content
4-22 Communications 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 Powermonitor 3000 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.
Communications 4-23 Figure 4.3 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.
4-24 Communications I/O Type Communications Powermonitor 3000 units with optional Remote I/O, EtherNet/IP (Series B) and DeviceNet communications provide I/O type 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.
Communications 4-25 The RS-485 communications standard supports multi-drop communications between a master station and up to 31 slaves on a single network up to 1219 meters (4000 feet) long. For satisfactory communications performance, however, we recommend connecting no more than 8 to 12 Powermonitor 3000 units to an RS-485 multi-drop network.
4-26 Communications IMPORTANT Because the floating-point word order in the ControlLogix controller is reversed from that in the Powermonitor 3000, your ladder logic will need 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.

Communications 4-29 For function code 03, 04 and 16, if any undefined starting address is sent to the Powermonitor 3000, exception code 2 will be returned and error code 6 will occur. If the starting addresses other than the first Modbus address of the data tables are sent to the slave with function code 16, this error code will also occur. For function codes 03 and 04, the starting address may be any address within the data table.
4-30 Communications DeviceNet Communications Option The Powermonitor 3000 with optional DeviceNet communications operates as a slave device on a DeviceNet network. It will serve data to a DeviceNet master station such as a PLC-5 or SLC 500 DeviceNet scanner, a ControlLogix DeviceNet bridge module, a PanelView operator terminal and RSLinx direct and pass-thru DeviceNet drivers.
Communications 4-31 Total Scan Time = ( 1 + R ) • D Where: R = Foreground to Background Poll Ratio D = Interscan Delay Change of State I/O messaging (COS) reports data only when the content of the I/O table changes. COS messaging can be more efficient for discrete applications because it tends to reduce the network traffic. If you have configured the input message table to include metering data, however, COS may reduce the network efficiency because the data constantly changes.
4-32 Communications In the SLC 500 and PLC-5, you assemble the explicit message header in an integer file and transfer it to the scanner module. When the response is received, you transfer the response from the scanner to another integer file. The message header consists of 6 words organized as follows: Table 4.6 Message Word High byte Low byte Header 0 Transmit ID Command 1 Port Size 2 Service MAC ID 3 Class 4 Instance 5 Attribute 6 Data to write if applicable Body 7 ...
Communications 4-33 • 0E hex (14 decimal) = Get_Attribute_Single. Requests a read of the entire assembly instance defined in the transaction body. • 10 hex (16 decimal) = Set_Attribute_Single. Writes the data contained in the message to the assembly instance defined in the transaction body. TIP A convenient way to build Words 0, 1 and 2 is to multiply the high byte value by 256 and add the low byte value, using decimal values for each parameter. Example: TXID = 121; Command = 1.
4-34 Communications The example above is a ControlLogix message instruction to read the user-configured table, assembly instance 37. TIP Because the floating-point word order in the ControlLogix controller is reversed from that in the Powermonitor 3000, your ladder logic will need to reverse the word order so the data may be interpreted correctly. The SWPB instruction performs this function. Up to four concurrent explicit messaging connections are supported by the DeviceNet communications port.

Chapter 5 Setpoint Programming and Operation Setpoint operation provides a method other than communications for the Powermonitor 3000 to be used in and interact with power and energy applications.
5-2 Setpoint Programming and Operation TIP You should assign each setpoint a unique action type. If more than one setpoint are assigned an action type, unpredictable output action may result. You may read setpoint output flags in Table A.3 Discrete Data and Table A.2 Remote I/O, DeviceNet, EtherNet/IP and ControlNet I/O Messaging. You may read only the first 8 setpoint output flags in the discrete input table with optional Remote I/O communications.
Setpoint Programming and Operation 5-3 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.
5-4 Setpoint Programming and Operation Figure 5.3 Under Forward Setpoint Operation Parameter Value
Setpoint Programming and Operation 5-5 Equal Setpoint An equal setpoint activates when the monitored parameter equals the Setpoint High Limit for a time greater than the Setpoint Action Delay. An equal setpoint releases when the monitored parameter does not equal the Setpoint High Limit for a period of time greater than the Setpoint Release Delay. The Setpoint Low Limit is not used for equal and not equal setpoints.

5-10 Setpoint Programming and Operation ATTENTION These examples are intended to demonstrate setpoint configuration only. They should not be used as sample application programming references. Carefully consider all control, operational and safety issues when designing and implementing setpoint operations.
Setpoint Programming and Operation 5-11 Example 3 – Oscillogram capture on demand: To use setpoint 3 to capture an oscillogram when you push a button connected to status input number 2, you could use these settings. Setpoint number 3 Setpoint type 32 - Status input No.
5-12 Setpoint Programming and Operation • Password: A valid password is required to enable, disable or clear the min/max log. Write a value of –1 when simply selecting a setpoint • Setpoint number: Selects a setpoint for configuration or read-back; or indicates the currently selected setpoint on a read. • Read-back mode: 0 selects auto-increment; 1 selects manual-increment (only mode supported by DeviceNet and Ethernet units) • Setpoint type: Refer to Table 5.
Chapter 6 I/O Operations The Powermonitor 3000 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 240 VAC or 250 VDC. This set of contacts is also rated to meet IEEE C37.90 requirements for power circuit breaker tripping duty.
6-2 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 Powermonitor 3000 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 6-3 Setpoint Control Set the Control source to a value of 7 to enable setpoints to control the selected output. Discrete I/O Control Set the Control Source to a value of 8 to enable Ethernet Series B, ControlNet, DeviceNet, or Remote I/O to have exclusive control over the Powermonitor 3000 output via I/O messaging.
6-4 I/O Operations Communications Loss Behavior IMPORTANT The relay output contacts and solid-state KYZ output contacts on the Powermonitor 3000 may be used to control other devices through setpoint control or communications, The response of these outputs to a communications failure is configurable by the user. Be sure to evaluate the safety impact of the output configuration on your plant or process.
I/O Operations Status Input Operations 6-5 The Powermonitor 3000’s two self-powered status inputs provide a number of flexible configuration options that help customize the Powermonitor 3000 operation to meet the requirements of your specific application. Counters You may use the Powermonitor 3000 to monitor discrete events such as circuit breaker status or kWh pulses from a legacy electrical energy, steam, gas or other type of meter.
6-6 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 7-2.
Chapter 7 Data Logging Its inherent data logging capability makes the Powermonitor 3000 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.
7-2 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 make this configuration setting using the Display Module by navigating through these menus: PROG > PASS? > CONFIGURATION > EVENT LOG and setting the Log Status Inputs parameter from No to Yes. You may also make this selection using communications.
Data Logging 7-3 Table 7.
7-4 Data Logging Table 7.
Data Logging 7-5 Reading Data from the Event Log Using Communications The Event Log uses the indexed read method. Table A.26 is the Read-back Select table and Table A.27 is the Results table.
7-6 Data Logging For the M8 model, you may use the Event record internal identifier and the Event text available flag for reading and writing user comments. Please refer to the section immediately below. TIP The Powermonitor 3000 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.
Data Logging 7-7 This read/write table contains 22 integer elements including the following: • Password: A valid password is required to write a user comment; write a value of -1 to select a record for read-back • Write type: 0 selects a record for readback; 1 selects a record for writing a new user comment (prevents inadvertent creation of a user comment) • DeviceNet unique write identifier • Text block number: 1 for the first 26, or 2 for the last 24 characters in the user comment string • Event record
7-8 Data Logging • • • • • Password: -1 Write type: 0 DeviceNet unique write identifier: as applicable Text block #: 1 Event record internal identifier: from Table A.27, element 1; selects record to read The remaining records may remain 0. The next read of Table A.50 returns the first 26 characters in the user comment. The next write is identical except the Text block # must be 2. The next read returns the last 24 characters in the user comment.
Data Logging TIP 7-9 If you use the Powermonitor 3000 with an energy logging software such as RSEnergyMetrix, 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 less frequent polling and automatic data repopulation of the energy database.
7-10 Data Logging Examples Example 1: A user wants to log kW every 15 minutes and wants to know how many records the log will contain and how long a time that will cover. The first formula applies: ( 7 – 0 ) • 65524 D = -------------------------------------(1 • 4) + 6 Fill and hold mode allows logging the most records. Logging only 1 parameter per record, the formula results in a total of 45,866 records after rounding down. Logging every 15 minutes, this log configuration will log 15.8 months of kW data.
Data Logging 7-11 Setting up the Trend Log You configure the Trend Log by performing a table write to Table A.21 with the desired configuration settings. This read/write data table contains 26 integer elements including: • Password: Required to configure logging, you may use -1 for read-back selection • DeviceNet unique write identifier • Read-back mode: See below; must be a valid entry even if read-back is not being selected at this time • Logging interval: Interval in seconds (1 to 3,600).
7-12 Data Logging Reading Data from the Trend Log To read the Trend Log, use the indexed read method. A write to Table A.21 selects which trend log record is read next. There are a number of auto-increment and manual-increment options that may be selected by writing to the Read-back Mode element in Table A.21: 0. Auto-increment / start at beginning: Start at the oldest log record and index to the next record after each read of the results table 1.
Data Logging 7-13 Table A.22 Trend Log Results is a read-only table of 14 (DeviceNet) or 22 (all other communications options) floating-point elements as follows: • Reserved element: returns 0 • Internal identifier: increments by 1 to 15 for each trend log record then rolls over to 0 • Time stamp: in 4-element timestamp format. See page 3-28. • User-selected parameters: parameters you selected when you configured the Trend Log.
7-14 Data Logging Interfacing with the Min/Max Log Using Communications Write Min/max Log configuration settings and command using a table write to Table A.23 Min/Max Log Configuration/Read-Back Select. Access data in the Min/max Log using the indexed read method. Write to Table A.23 to select the read-back mode and/or which of 74 min/max records to return on the next read of Table A.25 Min/Max Log Results. Table A.
Data Logging 7-15 Table 7.3 Min/Max Log Parameter Listing Param.
7-16 Data Logging Table A.25 Min/Max Log Results is a read-only data table consisting of 11 floating-point elements containing the following information: • Parameter #: See Table 7.3 above • Min and max values • Timestamps: for Min and Max values in four-element timestamp format Time-of-use The Powermonitor 3000 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.

Default 7 (7 Hex, 12:00 noon to 2:59 p.m.) Reading Time-of-Use Log Data The Powermonitor 3000 stores the TOU log in three sets of 13 records each, one set for real energy and demand, a second for reactive energy and demand, and the last for apparent energy and demand.
Chapter 8 Advanced Features In this chapter we will 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 Powermonitor 3000 input terminals. A client application reads oscillography records using the indexed read method.
8-2 Advanced Features • Capture number: selects a capture for read-back or returns the last capture selected. Range 1 to 8 (M6) or 1 to 2 (M8). Default 1. • Channel number: selects a channel number or returns the last channel number selected. Range: 1 = V1, 2 = I1, 3 = V2, 4 = I2, 5 = V3, 6 = I3, 7 = I4. Default 1. • Block number: selects a data block for the next read or returns the last block selected. Range depends on communications type. See below. Default 1.
Advanced Features 8-3 Block Number The block number and the total number of data reads required to read an entire capture depend on the communications option and the capture type. See Table 8.1. The block number range is 1 to the number of Data reads required listed in the table. Capture Type The properties associated with the capture type options are listed in Table 8.1. You may select a capture type that best suits your application requirements.
8-4 Advanced Features • Manual increment: each write of Table A.39 specifies the channel and block to be read in the next read of Table A.40. Successive reads of the results table will return the same block of data each time if no read-back select write is done. Reading Oscillograph Data Read oscillograph data from Table A.40 Oscillograph Results using the indexed read method. Oscillograph data is not available via Modbus communications.
Advanced Features 8-5 N datapoint_oscillogram = ( N block – 1 ) + N datapoint_this_read Ndatapoint_oscillogram = the sequence number of the data point in the oscillogram channel Nblock = the block number Ndatapoint_this_read = the data point number (1 to 20 or 1 to 50) in the current read The total number of data points is 4600 for capture type 0, 1 and 2 and 9200 for capture types 3, 4 and 5.
8-6 Advanced Features Factor = ( 691.1 • 1.414 ) ⁄ 8192 • ( 13800 ⁄ 120 ) = 13.72 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 1,000 gives the trigger source: 0 = none; 1 to 20 = setpoint number; 21 = native communications; 22 = optional communications.

8-8 Advanced Features 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. Crest Factor is the ratio of the peak to the RMS. Crest Factor = Peak Value ⁄ RMS Value A pure sinusoid Crest Factor equals 2. TIF Another method of measuring signal distortion is the Telephone Influence Factor, sometimes called the Telephone Interference Factor.
Advanced Features 8-9 increase the heat rise in a power transformer. The additional harmonic heating may cause a transformer to exceed designed temperature limits even though the RMS current is less than the transformer rating. The K-Factor is used as justification to oversize a power transformer to allow extra margin for harmonic losses or to select an appropriate K-Factor rated transformer. A K-Factor rated transformer is the preferred choice since it has known performance in the presence of harmonics.
8-10 Advanced Features proper limits for each of the individual harmonics and the TDD specified in the table columns. IEEE-519 also recommends maximum voltage distortion levels that the utility should remain below. Table 11.1 specifies these limits based on the magnitude of the line to line voltage at the PCC. Once configured, the 1404-M6 will automatically monitor the system voltage and current for IEEE-519 compliance.
Advanced Features TIP 8-11 The remaining elements listed below are reserved in the M4 and M5 models, return 0 on a read and must be 0 on a write. • Individual harmonic data type: selects% distortion (0) or magnitude (1) on subsequent reads of the individual results tables.

8-14 Advanced Features Figure 8.1 Sag and Swell The pre-defined setpoint configuration for the detection of sag and swell is based on the IEEE-1159 standard. Although the default setpoint configuration is applicable as-is for many sag and swell applications, it may be necessary to alter the setpoint configuration to adjust the unit’s sensitivity to sags and swells for your particular application.
Advanced Features TIP 8-15 Refer to Chapter 5, Setpoint Programming and Operation for more information on setpoints. If the nominal system voltage setting is changed, the high and low limits for setpoint #19 and #20 are automatically adjusted to 90% and 110% of the nominal system voltage. To effectively use sag and/or swell detection: 1. Set ‘RMS result averaging’ to 0 (no averaging) for the quickest setpoint response to changes in input voltage. 2.
8-16 Advanced Features Load Factor 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 communications 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.
Advanced Features 8-17 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 Table A.41. Load factor log data is not available via Modbus communications. This read/write table contains 6 integer elements as follow: • Password: required for changing the auto clear/reset day or manual clear/reset command. Use -1 if only selecting read-back mode or record. Range 0000 to 9999, default 0000.
8-18 Advanced Features • Peak demand current: expressed in VARs. Range 0.0 to 999.9*1021 • Average demand current: expressed in VARs. Range 0.0 to 999.9*1021 • Load factor current: expressed in per cent. Range 0.0 to 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 to 123199 (mmddyy).

You select either voltage channels or current channels with the Detection mode parameter.
Advanced Features 8-21 • 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 to 999.0 * 1021 • Current: four RMS current results (L1, L2, L3, L4) for the current Cycle number. Range 0.0 to 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.
8-22 Advanced Features • 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.
Advanced Features 8-23 • Channel number: in the range 1 to 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. See above. • Transient capture identifier: range 0 to 30,000, rolls over to 0 • Transient capture data points: see below Transient Capture Data Points The results table contains 20 data points for optional DeviceNet communications or 50 data points for all other communications options.
8-24 Advanced Features • 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. A data client may use the Capture identifier to associate the transient capture with corresponding metering data and event log data.

Appendix C Sample Applications Introduction This Appendix contains sample applications including ladder diagrams to help you get started in setting up communications between your application and a Powermonitor 3000. The application samples depict basic methods for reading and writing data between a Powermonitor 3000 and your programmable controller or other application. Expand on these basic steps to customize your application to meet your business needs. The sample applications included are: 1.
C-2 Sample Applications System Clock Sample Applications The Powermonitor 3000 system clock (date and time) is an ideal sample application for several reasons: • It is important to set the system clock so that data log records, oscillograms, etc.
Sample Applications C-3 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 Powermonitor 3000 with a password of 0 to January 1, 2003 at 12:00 midnight: The Read Clock from PM3K and Set Clock from SLC bits are used to initiate the messages, and are reset when the message instruction either completes successfully or an error occurs.
C-4 Sample Applications code, if the message rungs are controlled programmatically, ensure that only one message is enabled at a time.
Sample Applications C-5 The Write message setup is similar: MicroLogix 1500 using Modbus NEW FROM RICH MORGAN Publication 1404-UM001D-EN-E - October 2004
C-6 Sample Applications PLC-5 Controller Using Remote I/O The second example also reads and writes the Powermonitor 3000 date and time but using a PLC-5 controller and Remote I/O. In this example, a Powermonitor 3000 has a logical address of Rack 1, Group 0. The PLC-5 data table files used are the same as in the previous example. The main difference is that this example uses block transfer instructions rather than message instructions, and the block transfer length determines which data table is selected.
Sample Applications C-7 Ladder Diagram EtherNet/IP and ControlLogix The third example reads and writes the Powermonitor 3000 date and time data table using a ControlLogix controller and EtherNet/IP communications.
C-8 Sample Applications protocol must be CIP or CSP/CIP dual stack to enable communications with the ControlLogix controller. 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. The following figure shows the Set_date_time to set the Powermonitor 3000 clock to January 1, 2003 at midnight. The tag PM3K_Date_Time shows the results of a read 7.13 seconds after the write.
Sample Applications C-9 Ladder Diagram Read_clock_from_PM3K MSG Type - PLC5 Typed Read Message Control 0 Read_Time Read_Time.DN ... EN DN ER Read_clock_from_PM3K U Read_Time.ER Set_time_from_CLX MSG Type - PLC5 Typed Write Message Control 1 Set_time.DN Set_time ... EN DN ER Set_time_from_CLX U Set_time.ER (End) Message Setup Dialogs The example uses PLC-5 Typed read and write message types. The setup dialogs are similar to those found on page 4-41 and page 4-42.
C-10 Sample Applications Publication 1404-UM001D-EN-E - October 2004

EN DN ER Read_clock_from_PM3K U Read_Time.ER Set_clock_from_PM3K 1 MSG Type - CIP Generic Message Control Set_Time.DN Set_Time ... EN DN ER Set_clock_from_PM3K U Set_Time.
C-12 Sample Applications The communications tab of the message setup simply shows the module name in the I/O configuration for this example. The Write message dialog is similar to the Read: 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 You may create a simple data transfer application using RSLinx direct data exchange (DDE) capabilities and a DDE client such as Microsoft ExcelTM.
Sample Applications C-13 real-time clock in a Powermonitor 3000. You may utilize similar techniques to transfer data to and from any Powermonitor 3000 data tables. Setting up a DDE topic in RSLinx Follow these steps to create a DDE topic in RSLinx. You will need RSLinx OEM, Professional, Gateway or SDK to support DDE communications. 1. Establish communications between RSLinx and your Powermonitor using the communications method of your choice. The example uses the native DF1 communications port 2.
C-14 Sample Applications 5. Click on the Data Collection tab. Select SLC 5/03+ as the Processor Type. Leave the rest of the settings as default.
Sample Applications C-15 6. Click Apply and confirm when prompted. Click the Advanced Communications tab to verify the driver and path settings in the topic. Click the Done button. 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 Powermonitor 3000.
C-16 Sample Applications 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.
Sample Applications C-17 To read the date and time from the Powermonitor 3000, click the Read graphic element. To write the data and time to the Powermonitor 3000, enter the desired data and time into the worksheet along with the Powermonitor 3000 password (default = 0) and click the Write graphic element. Date and Time Summary You may use the examples above as building blocks to create applications to meet your business needs.
C-18 Sample Applications Refer to Devicenet Scanner Module Installation Instructions, publication 1747-5.8, for a detailed description of all coding. Table C.1 TXID cmd/status Port Size Service MAC ID Class Instance Attributes Word M0:1.224 A unique TXID (Transmit Identifier) and Command byte is needed for this word. The valid command codes are: • 1 = Execute transaction block • 4 = Delete transaction from response queue A command byte of 1 is used first to start the explicit message.
Sample Applications C-19 Word M0:1.225 A port number and transaction body size is needed for this word. The port number is the DeviceNet scanner port that handles this transaction; an SLC-500 uses port 0 and the PLC-5 uses port 0 or 1. The size is the number of bytes (2 bytes = 1 word) in the transaction body which is 6 (6 bytes = 3 words). Table 3.C Port Size Port x 256 + Size 0 x 256 + 6 6 Word M0:1.226 A service code and MAC ID is needed for this word.
C-20 Sample Applications Word M0:1.2278 The instance number is the second word of the transaction body; instance 14 is used to retrieve the real-time voltage, current, and frequency metering information. Table 3.F Instance 14 Word M0:1.229 The attribute number is the third word of the transaction body; attribute 3 is used to get the metering information. Table 3.G Attribute 3 SLC 500 Sequencer Operation This example uses a sequencer instruction and indirect addressing to optimize program operation.

Sample Applications C-31 Publication 1404-UM001D-EN-E - October 2004
C-32 Sample Applications Timer2 delays evaluating the write status until the Powermonitor 3000 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.
Sample Applications Communicating with a SLC5/05 (1747-L552) Controller and ControlNet Scanner (1747-SCNR), Unscheduled Messaging C-33 The Power Energy and Management Systems development team tested the following example ladder. The scan times for execution of the ladder are as follows. Table C.
C-34 Sample Applications Table C.11 Bit # Importance N7:0 Read/Write N7:0/15 EN - Written to by the ladder to enable communication transaction. R/W N7:0/14 Unused N/A N7:0/13 DN bit - Response received R N7:0/12 ER bit - Error bit returned form SCNR scanner R N7:0/11 CO - Continuous mode Not used N/A N7:0/10 EW - Message taken into account by 1747 - SCNR scanner R N7:0/9 SUCCESS - Used by ladder for notification R of successful communication transfer.
Sample Applications C-35 Table C.12 Word # Description of Function 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. Writing a 1 starts the process for writing an assembly instance of the power monitor. Writing a 2 starts the read process of assembly instance from the power monitor.
C-36 Sample Applications 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. 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. N9:9 is the size of the table in words for a 1404-M805A-CNT A.
Sample Applications C-37 Powermonitor 3000 Ladder Example for SLC through SCNR 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. Copies the request from the CIP_SETUP file to N7 first 9 words. Moves a 0 to M0 scanner locat ion M0:3.
C-38 Sample Applications When a write of a float file is being performed it is necessary to swap the words in the float file before sending the write re quest. 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.
Sample Applications C-39 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 t o the F8:0 file after swapping words from the incomming message.
C-40 Sample Applications 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.
Sample Applications C-41 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. A size of 32 was selected to handle all power monitor files.
C-42 Sample Applications When the word swapping is complete transfer the results into F8 FLT_DATA file.
Sample Applications C-43 Initialize N12:0 word counter. Copy F13 configuration float data to N11 temporary file. 0000 MOV Move Source SBR Subroutine Dest COP Copy File Source Dest Length 0 0< N12:0 30< #F13:0 #N11:0 32 Continue to swap words until 32 floats have been converted. This is enough to handle all power monitor files.
C-44 Sample Applications When the swap operation is complete copy the temp file to the designated WR_TRANSFR file.

Glossary Glossary Term ampere A unit of electrical current or rate of flow of electrons. One volt across ‘one ohm of resistance causes a current flow of one ampere. A flow of one coulomb per second equals one amp. apparent power The product of voltage magnitude and current magnitude in a circuit. Units are VA or some multiple thereof.
Glossary 18 coil This is a Modbus mapped location used for reading and writing bit length data. These bits typically reflect the value of the discrete outputs. Powermonitor 3000 does 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 19 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 does 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 20 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 Powermonitor 3000 slave device, the locations are defined by the Modbus Memory Map.
Glossary 21 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 22 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 percent is typical) of the highest historical peak demand, depending on which is largest.
Glossary 23 slave address This is the numerical label for slave devices. Valid slave device addresses are in the range of 0 to 247 decimal. The individual slave devices are assigned addresses in the range of 1 to 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 24 watt demand Power during a predetermined interval. The highest average, i.e. 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.
