Chapter 1 What Are ControlLogix Analog I/O Modules? Introduction This chapter provides an overview of the ControlLogix analog I/O modules to explain to you how they operate.
Chapter 1 What Are ControlLogix Analog I/O Modules? ControlLogix Analog I/O Module Features Feature Description Calibration ControlLogix analog I/O module ships from the factory with factory calibration. You can recalibrate the module calibration on a channel-by-channel or module-wide basis to increase accuracy in customer-specific applications, if necessary.
What Are ControlLogix Analog I/O Modules? I/O Module in the ControlLogix System Chapter 1 ControlLogix modules mount in a ControlLogix chassis and use a removable terminal block (RTB) or a Bulletin 1492 interface module(1) cable to connect to all field-side wiring. Before you install and use your module, you should do the following: • Install and ground a 1756 chassis and power supply(2). To install these products, refer to the publications listed in Additional Resources on page 13.
Chapter 1 What Are ControlLogix Analog I/O Modules? Parts Illustration of the ControlLogix Analog I/O Module 5 3 Removable Terminal Block 2 4 6 1 40200-M 18 Item Description 1 Backplane connector - Interface for the ControlLogix system that connects the module to the backplane. 2 Top and bottom guides - Guides provide assistance in seating the RTB or IFM cable onto the module. 3 Status indicators - Indicators display the status of communication, module health, and input/output devices.
What Are ControlLogix Analog I/O Modules? Module Identification and Status Information Chapter 1 Each ControlLogix I/O module maintains specific identification information that separates it from all other modules. This information assists you in tracking all the components of your system. For example, you can track module identification information to be aware of exactly what modules are located in any ControlLogix rack at any time.
Chapter 1 What Are ControlLogix Analog I/O Modules? Preventing Electrostatic Discharge This module is sensitive to electrostatic discharge. ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards.
Chapter 2 Analog I/O Operation in the ControlLogix System Introduction I/O modules are interfaces between the controller and the field devices that comprise the ControlLogix system. Analog signals, which are continuous, are converted by the module and used by the controller to mandate field-device results. This chapter describes how analog I/O modules operate within the ControlLogix system.
Chapter 2 Analog I/O Operation in the ControlLogix System Typically, each module in the system will have one owner only. Input modules can have more than one owner. Output modules, however, are limited to a single owner. For more information on the increased flexibility provided by multiple owners and the ramifications of using multiple owners, see Configuration Changes in an Input Module with Multiple Owners on page 34.
Analog I/O Operation in the ControlLogix System Chapter 2 3. After running RSNetWorx software, perform an online save of the RSLogix 5000 project so the configuration information that RSNetWorx software sends to the controller is saved.. IMPORTANT Direct Connections You must run RSNetWorx for ControlNet software whenever a new I/O module is added to a scheduled ControlNet chassis.
Chapter 2 Analog I/O Operation in the ControlLogix System Input Module Operation In traditional I/O systems, controllers poll input modules to obtain their input status. In the ControlLogix system, a controller does not poll analog input modules after a connection is established. Instead, the modules multicast their data periodically. The frequency depends on the options chosen during configuration and where in the control system that input module physically resides.
Analog I/O Operation in the ControlLogix System Chapter 2 Requested Packet Interval (RPI) This configurable parameter also instructs the module to multicast its channel and status data to the local chassis backplane. The RPI, however, instructs the module to produce the current contents of its on-board memory when the RPI expires, (that is, the module does not update its channels prior to the multicast).
Chapter 2 Analog I/O Operation in the ControlLogix System If the RTS value is greater than the RPI, the module produces at both the RTS rate and the RPI rate. Their respective values will dictate how often the owner-controller will receive data and how many multicasts from the module contain updated channel data. In the example below, the RTS value is 100 ms and the RPI value is 25 ms. Only every fourth multicast from the module will contain updated channel data.
Analog I/O Operation in the ControlLogix System Input Modules in a Remote Chassis Chapter 2 If an input module physically resides in a remote chassis, the role of the RPI and the module’s RTS behavior change slightly with respect to getting data to the owner-controller, depending on what network type you are using to connect to the modules.
Chapter 2 Analog I/O Operation in the ControlLogix System Best Case RTS Scenario In the best case scenario, the module performs an RTS multicast with updated channel data just before the ‘reserved’ network slot is made available. In this case, the remotely-located owner-controller receives the data almost immediately. Worst Case RTS Scenario In the worst case scenario, the module performs an RTS multicast just after the ‘reserved’ network slot has passed.
Analog I/O Operation in the ControlLogix System Output Module Operation Chapter 2 The RPI parameter governs exactly when an analog output module receives data from the owner-controller and when the output module echoes data. An owner-controller sends data to an analog output module only at the period specified in the RPI. Data is not sent to the module at the end of the controller’s program scan.
Chapter 2 Analog I/O Operation in the ControlLogix System Output Modules in a Remote Chassis If an output module resides in a remote chassis, the role of the RPI changes slightly with respect to getting data from the owner-controller, depending on what network type you are using to connect to the modules.
Analog I/O Operation in the ControlLogix System Chapter 2 Worst Case RPI Scenario In the worst case scenario, the controller sends the data just after the ‘reserved’ network slot has passed. In this case, the module does not receive the data until the next scheduled network slot. IMPORTANT These best and worst case scenarios indicate the time required for output data to transfer from the controller to the module once the controller has produced it.
Chapter 2 Analog I/O Operation in the ControlLogix System Listen-only Mode Any controller in the system can listen to the data from any I/O module (that is, input data or ‘echoed’ output data) even if the controller does not own the module. In other words, the controller does not have to own a module’s configuration data to listen to it. During the I/O configuration process, you can specify one of several ‘Listen-Only’ modes in the Comm Format box on the New Module dialog box.
Analog I/O Operation in the ControlLogix System Multiple Owners of Input Modules Chapter 2 Because ‘Listening controllers’ lose their connections to modules when communication with the owner stops, the ControlLogix system lets you define more than one owner for input modules. IMPORTANT Only input modules can have multiple owners. If multiple owners are connected to the same input module, they must maintain identical configuration for that module.
Chapter 2 Analog I/O Operation in the ControlLogix System Configuration Changes in an Input Module with Multiple Owners You must be careful when changing an input module’s configuration data in a multiple owner scenario. When the configuration data is changed in one of the owners, for example, Controller A, and sent to the module, that configuration data is accepted as the new configuration for the module. Controller B continues to listen, unaware that any changes have been made in the module’s behavior.
Chapter 3 ControlLogix Analog I/O Module Features Introduction This chapter describes features that are common to all ControlLogix analog I/O modules. ControlLogix analog input modules convert an analog signal of either volts, millivolts, milliamps, or ohms that is connected to the module's screw terminals into a digital value. The digital value that represents the magnitude of the analog signal is then transmitted on the backplane to either a controller or other control entities.
Chapter 3 ControlLogix Analog I/O Module Features Removal and Insertion Under Power (RIUP) All ControlLogix I/O modules can be inserted and removed from the chassis while power is applied. This feature allows greater availability of the overall control system because, while the module is being removed or inserted, there is no additional disruption to the rest of the controlled process.
ControlLogix Analog I/O Module Features Chapter 3 Electronic Keying The electronic keying feature automatically compares the expected module, as shown in the RSLogix 5000 I/O Configuration tree, to the physical module before I/O communication begins. You can use electronic keying to help prevent communication to a module that does not match the type and revision expected.
Chapter 3 ControlLogix Analog I/O Module Features General Tab IMPORTANT Changing electronic keying selections online may cause the I/O communication connection to the module to be disrupted and may result in a loss of data. Exact Match Exact Match Keying requires all keying attributes, that is, Vendor, Product Type, Product Code (catalog number), Major Revision, and Minor Revision, of the physical module and the module created in the software to match precisely to establish communication.
ControlLogix Analog I/O Module Features EXAMPLE Chapter 3 In the following scenario, Exact Match keying prevents I/O communication: • The module configuration is for a 1756-IB16D module with module revision 3.1. The physical module is a 1756-IB16D module with module revision 3.2. In this case, communication is prevented because the Minor Revision of the module does not match precisely.
Chapter 3 ControlLogix Analog I/O Module Features With Compatible keying, you can replace a module of a certain Major Revision with one of the same catalog number and the same or later, that is higher, Major Revision. In some cases, the selection makes it possible to use a replacement that is a different catalog number than the original. For example, you can replace a 1756-CNBR module with a 1756-CN2R module. Release notes for individual modules indicate the specific compatibility details.
ControlLogix Analog I/O Module Features EXAMPLE Chapter 3 In the following scenario, Compatible keying allows I/O communication: • The module configuration is for a 1756-IB16D module with module revision 2.1. The physical module is a 1756-IB16D module with module revision 3.2. In this case, communication is allowed because the major revision of the physical module is higher than expected and the module determines that it is compatible with the prior major revision.
Chapter 3 ControlLogix Analog I/O Module Features Disabled Keying Disabled Keying indicates the keying attributes are not considered when attempting to communicate with a module. Other attributes, such as data size and format, are considered and must be acceptable before I/O communication is established. With Disabled keying, I/O communication may occur with a module other than the type specified in the I/O Configuration tree with unpredictable results. We generally do not recommend using Disabled keying.
ControlLogix Analog I/O Module Features EXAMPLE Chapter 3 In the following scenario, Disable keying allows I/O communication: • The module configuration is for a 1756-IA16 digital input module. The physical module is a 1756-IB16 digital input module. In this case, communication is allowed because the two digital modules share common data formats.
Chapter 3 ControlLogix Analog I/O Module Features Access to System Clock for Timestamp Functions Controllers within the ControlLogix chassis maintain a system clock. This clock is also known as the coordinated system time (CST). You can configure your analog I/O modules to access this clock and timestamp input data or output echo data when the module multicasts to the system. You decide how to timestamp data when you choose a Communication Format on the New Module dialog box.
ControlLogix Analog I/O Module Features Chapter 3 Status Indicator Information Each ControlLogix analog I/O module has status indicators on the front of the module that lets you check the module health and operational status of a module. Status Description Calibration Display indicates when your module is in the calibration mode. Module Display indicates the module’s communication status. For a list of status indicators and descriptions, see Troubleshoot Your Module on page 273.
Chapter 3 ControlLogix Analog I/O Module Features Sensor Offset You can add this offset directly to the input or output during calibration calculation. The purpose of this feature is to let you compensate for any sensor offset errors which may exist, such offset errors are common in thermocouple sensors. To set a sensor offset, see page 210 in Chapter 10.
ControlLogix Analog I/O Module Features Chapter 3 Module Inhibiting Module inhibiting lets you indefinitely suspend a connection between an owner-controller and an analog I/O module. This process can occur in either of the following ways: • You write configuration for an I/O module but inhibit the module to prevent it from communicating with the owner-controller. In this case, the owner does not establish a connection and configuration is not sent to the module until the connection is uninhibited.
Chapter 3 ControlLogix Analog I/O Module Features Relationship Between Module Resolution, Scaling, and Data Format The following three concepts listed below are closely related and must be explained in conjunction with each other. • Module Resolution • Scaling • Data Format as Related to Resolution and Scaling Module Resolution Resolution is the smallest amount of change that the module can detect. Analog input modules are capable of 16-bit resolution.
ControlLogix Analog I/O Module Features Chapter 3 The table lists the resolution for each module’s range. Current Values Represented in Engineering Units Module Range Number of significant bits Resolution 1756-IF16 and 1756-IF8 +/- 10.25V 16 bits 320 µV/count 0…10.25V 160 µV/count 0…5.125V 80 µV/count 0…20.5 mA 0.32 µA/count 1756-IF6CIS 0 mA…21 mA 16 bits 0.34 µA/count 1756-IF6I +/- 10.5V 16 bits 343 µV/count 1756-IR6I 1756-IT6I and 1756-IT6I2 0…10.5V 171 µV/count 0…5.
Chapter 3 ControlLogix Analog I/O Module Features Scaling With scaling, you change a quantity from one notation to another. For ControlLogix analog I/O modules, scaling is only available with the floating point data format. When you scale a channel, you must choose two points along the module’s operating range and apply low and high values to those points. For example, if you are using the 1756-IF6I module in current mode, the module maintains a 0…21 mA range capability.
ControlLogix Analog I/O Module Features Chapter 3 The module may operate with values beyond the 4…20 mA range. If an input signal beyond the low and high signals is present at the module (that is, 3 mA), that data will be represented in terms of the engineering units set during scaling. The table shows example values that may appear based on the example mentioned above. Current Values Represented in Engineering Units Current Engineering Units Value 3 mA -6.
Chapter 3 ControlLogix Analog I/O Module Features In integer mode, input modules generate digital signal values that correspond to a range from -32,768…32,767 counts. The table lists the conversions of a generated digital signal to the number of counts. Input Signal to User Count Conversion Input Module Available Range Low Signal and High Signal and User Counts User Counts 1756-IF16/IF8 +/- 10V -10.25V 10.25V -32768 counts 32767 counts 0V 10.25V -32768 counts 32767 counts 0V 5.
ControlLogix Analog I/O Module Features Chapter 3 The table lists the conversions a generated digital signal to the number of counts. Output Signal to User Count Conversion Output Module Available Range Low Signal and High Signal and User Counts User Counts 1756-OF4/OF8 0…20 mA 0 mA 21.2916 mA -32768 counts 32767 counts -10.4336V 10.4336V -32768 counts 32767 counts 0 mA 21.074 mA -32768 counts 32767 counts -10.517V 10.
Chapter 3 ControlLogix Analog I/O Module Features Difference Between Integer and Floating Point The key difference between choosing integer mode or floating point mode is that the integer is fixed between -32,768…32,767 counts and floating point mode provides scaling to represent I/O data in specific engineering units for your application. Module resolution remains constant between the formats at 0.34 µA/count.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Introduction This chapter describes features specific to ControlLogix non-isolated, analog voltage/current input modules.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Choose a Wiring Method The 1756-IF16 and 1756-IF8 modules support these wiring methods: • Single-ended Wiring Method • Differential Wiring Method • High-speed Mode Differential Wiring Method After determining the wiring method you will use on your module, you must inform the system of that choice when you choose a Communication Format.
Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Chapter 4 Differential Wiring Method The differential wiring method is recommended for applications that may have separate signal pairs or a common ground is not available. Differential wiring is recommended for environments where improved noise immunity is needed. IMPORTANT This wiring method lets you use only half a module’s channels.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Choose a Data Format Data format determines the format of the data returned from the module to the owner-controller and the features that are available to your application. You choose a data format when you choose a Communication Format. When you choose a Communication Format, you can select one of two data formats: • Integer mode • Floating point mode The table shows features that are available in each format.
Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Features Specific to Non-Isolated Analog Input Modules Chapter 4 The table lists features that are specific to the 1756-IF16 and 1756-IF8 modules.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Module Filter The module filter is a built-in feature of the analog-to-digital convertor that attenuates the input signal beginning at the specified frequency. This feature is applied on a module-wide basis. The module attenuates the selected frequency by approximately -3dB or 0.707 of the applied amplitude. This selected frequency is also called the bandwidth of the module.
Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Chapter 4 Real Time Sampling This parameter instructs the module how often to scan its input channels and obtain all available data. After the channels are scanned, the module multicasts that data. This feature is applied on a module-wide basis. During module configuration, you specify a real time sampling (RTS) period and a requested packet interval (RPI) period.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Digital Filter The digital filter smooths input data noise transients for all channels on the module. This feature is applied on a per channel basis. The digital filter value specifies the time constant for a digital first order lag filter on the input. It is specified in units of milliseconds. A value of 0 disables the filter. The digital filter equation is a classic first order lag equation.
Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Chapter 4 Process Alarms Process alarms alert you when the module has exceeded configured high or low limits for each channel. You can latch process alarms. These are set at four user configurable alarm trigger points. • • • • High high High Low Low low IMPORTANT Process alarms are not available in integer mode or in applications using 1756-IF16 module in the single-ended, floating point mode.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Rate Alarm The rate alarm triggers if the rate of change between input samples for each channel exceeds the specified trigger point for that channel. IMPORTANT Rate alarms are not available in integer mode or in applications using 1756-IF16 module in the single-ended, floating point mode. The values for each limit are entered in scaled engineering units.
Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Chapter 4 Because the 1756-IF16 and 1756-IF8 modules can be applied in voltage or current applications, differences exist as to how a wire-off condition is detected in each application. IMPORTANT Be careful when ‘disabling all alarms’ on the channel because it also disables the underrange/overrange detection feature.
Chapter 4 Non-isolated Analog Voltage/Current Input Modules (1756-IF16, 1756-IF8) Wire-Off Conditions When the Wire-Off condition occurs Differential Current Applications These events occur • Input data for that channel changes to the scaled value associated with the overrange signal value of the selected operational range in floating point mode (minimum possible scaled value) or -32,768 counts in integer mode. • The ChxUnderrange (x=channel number) tag is set to 1.

Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Introduction This chapter describes features specific to the ControlLogix isolated analog voltage/current input module and the ControlLogix sourcing current loop input module..
Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Use the Isolated Power Source on the 1756-IF6CIS The 1756-IF6CIS module offers an internal power source on each channel. The source is current limited to 28 mA and allows the module to power a two-wire transmitter directly without the need for an external power supply. The transmitter can then vary the current to the analog input in proportion to the process variable being measured.
Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Chapter 5 The 1756-IF6CIS and 1756-IF6I modules also support features described in Chapter 3. See the table for some of these features.
Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Features Specific to the 1756-IF6I and 1756-IF6CIS Modules The table lists features that are specific to the 1756-IF6CIS and 1756-IF6I modules. Each feature is described later in this section.
Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Chapter 5 Notch Filter An analog-to-digital convertor (ADC) filter removes line noise in your application for each channel. Choose a notch filter that most closely matches the anticipated noise frequency in your application. Remember that each filter time affects the response time of your module. Also, the highest frequency notch filter settings also limit the effective resolution of the channel.
Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Real Time Sampling This parameter instructs the module to scan its input channels and obtain all available data. After the channels are scanned, the module multicasts that data. During module configuration, you specify a real time sampling (RTS) period and a requested packet interval (RPI) period.
Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Chapter 5 Digital Filter The digital filter smooths input data noise transients on each input channel. This value specifies the time constant for a digital, first-order lag filter on the input. It is specified in units of milliseconds. A value of 0 (zero) disables the filter. The digital filter is available only in applications that use floating point mode.
Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Process Alarms Process alarms alert you when the module has exceeded configured high or low limits for each channel.

Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Chapter 5 Rate Alarm The rate alarm triggers if the rate of change between input samples for each channel exceeds the specified trigger point for that channel. IMPORTANT EXAMPLE The rate alarm is available only for applications that use floating point mode. 1756-IF6CIS If you set an 1756-IF6I (with normal scaling in mA) to a rate alarm of 1.
Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I) Wire Off Detection IMPORTANT Be careful when ‘disabling all alarms’ on the channel because it also disables the underrange/overrange detection feature. If alarms are disabled, overrange/underrange is zero and the only way you can discover a wire-off detection is from the input value itself. If you need to detect a wire-off status, do not ‘disable all alarms’.

You can latch process alarms. These are set at four user configurable alarm trigger points. • • • • High high High Low Low low IMPORTANT Process alarms are available only in applications using floating point mode. The values for each limit are entered in scaled engineering units.
Chapter 6 Temperature-measuring Analog Modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2) Rate Alarm IMPORTANT You must use RSLogix 5000 software, version 12 or later, and module firmware revision 1.10 or later, to use the rate alarm for a non-ohm input on the 1756-IR6I module and a non-millivolt input on the 1756-IT6I and 1756-IT6I2 modules. The rate alarm triggers if the rate of change between input samples for each channel exceeds the specified trigger point for that channel.
Temperature-measuring Analog Modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2) Chapter 6 Wire Off Detection The ControlLogix temperature-measuring modules alert you when a wire has been disconnected from one of their channels. When a wire off condition occurs, two events occur: • Input data for that channel changes to a specific scaled value. • A fault bit is set in the owner-controller that may indicate the presence of a wire off condition.
Chapter 6 Temperature-measuring Analog Modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2) Wire Off Conditions In this application The following causes a wire off condition • Input data for the channel changes to the highest scaled temperature value associated with the selected thermocouple type.

Chapter 6 Temperature-measuring Analog Modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2) IMPORTANT The table lists temperature limits for sensors using the -12…78 mV range only. When the -12…30 mV range is used, temperature limits are truncated to the temperature value that corresponds to 30 mV. To see how to choose a thermocouple sensor type, see page 216. Temperature Units The 1756-IR6I, 1756-IT6I and 1756-IT6I2 modules provide the choice of working in Celsius or Fahrenheit.
Temperature-measuring Analog Modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2) Chapter 6 Wire Length Calculations The rule for determining the maximum thermocouple lead length without error is that the lead length’s error should be less than half of the module resolution.

Chapter 7 Non-isolated Analog Output Modules (1756-OF4 and 1756-OF8) Choose a Data Format Data format defines the format of channel data sent from the controller to the module, defines the format of the ‘data echo’ that the module produces, and determines the features that are available to your application. You choose a data format when you choose a Communication Format.
Non-isolated Analog Output Modules (1756-OF4 and 1756-OF8) Chapter 7 Ramping/Rate Limiting Ramping limits the speed that an analog output signal can change. This prevents fast transitions in the output from damaging the devices that an output module controls. Ramping is also known as rate limiting.
Chapter 7 Non-isolated Analog Output Modules (1756-OF4 and 1756-OF8) Open Wire Detection This feature detects when current flow is not present at any channel. The 1756-OF4 and 1756-OF8 modules must be configured for 0…20 mA operation to use this feature. At least 0.1 mA of current must be flowing from the output for detection to occur. When an open wire condition occurs at any channel, a status bit is set for that channel. For more information on the use of status bits, see page 159.
Non-isolated Analog Output Modules (1756-OF4 and 1756-OF8) Chapter 7 Clamp/Limit Alarms This function works directly with clamping. When a module receives a data value from the controller that exceeds clamping limits, it applies signal values to the clamping limit but also sends a status bit to the controller notifying it that the value sent exceeds the clamping limits.

Chapter 10 Configure ControlLogix Analog I/O Modules Introduction You must configure your module upon installation. The module will not work until it has been configured. In most cases, you will use RSLogix 5000 programming software to configure your analog I/O module. The programming software uses default configurations, such as RTS, RPI, and so forth, to get your I/O module to communicate with the owner-controller. However, there are situations in which you might want to modify the default settings.
Chapter 10 Configure ControlLogix Analog I/O Modules IMPORTANT This section focuses on configuring I/O modules in a local chassis. To configure I/O modules in a remote chassis, you must follow all the detailed procedures with two additional steps. See page 230 for details. RSLogix 5000 programming software must be installed on your computer to complete the procedures for both default and custom configurations.

Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration You can use ladder logic to perform run time services on your module. For example, page 212 explains how to unlatch alarms on the 1756-IF6I module by using RSLogix 5000 software. This appendix provides an example of how to unlatch those same alarms without using RSLogix 5000 software. In addition to performing run time services, you can use ladder logic to change configuration.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration This prioritization allows input channels to be sampled at the same frequency and the process alarms to be unlatched in the time between sampling and producing the real-time input data. One Service Performed Per Instruction Message instructions will only cause a module service to be performed once per execution.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C A graphic that looks like a ladder, with rungs, appears in the right side of the RSLogix 5000 software program. You attach run-time service, such as a message instruction, to the rungs and then download the information to a controller. You can tell that the rung is in Edit mode because of the ‘e’ at the left side of the rung. 3. Find, then click MSG (message) instruction on the instruction toolbar.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The New Tag dialog box appears with the cursor in the Name field. IMPORTANT We suggest you name the tag to indicate what module service the message instruction is sending. For example, if a message instruction is to unlatch a high alarm, then name the tag ‘High alarm unlatch’ to reflect this. 6. Choose from the options in the New Tag dialog box.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Field Name Description Style Leave blank. Constant Leave blank. Open MESSAGE Configuration Leave the box blank if you do NOT want to automatically access the Message Configuration screen when OK is clicked. You still can access the Message Configuration screen later by following the procedures on page 344. 7. Click OK.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Enter Message Configuration After creating a tag, you must enter certain parameters for the message configuration. This information is entered on the Configuration and Communication tabs of the Message Configuration dialog box. The Message Configuration dialog box is accessed by clicking the box with the ellipses (in the Message Control field).
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Configuration Tab The Configuration tab provides information on what module service to perform and where to perform it. RSLogix 5000 Software, Version 9 and Earlier RSLogix 5000 Software, Version 10 and Later The following table explains the relationship of the fields in the above dialog boxes.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Relationship of Message Configuration Parameters RSLogix 5000 Versions 9 and earlier RSLogix 5000 Versions 10 and later Description Object Type Class Object that you are sending a message to, such as the device object or a discrete output point. Object ID Instance Each object can have multiple instances. For example, a discrete output can have 16 points or instances of where a message can be sent.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C The table contains required output configuration information to perform output module services.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Unlatch Alarms in the 1756-IF6I Module Example rungs 0…4 show how to unlatch the following alarms in a 1756-IF6I module, named Slot_1_IF6I.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Configuration Dialog Boxes The example below shows the message configuration setting for rung 0 if using RSLogix 5000 software version 9 and earlier RSLogix 5000 Software, Version 9 and Earlier This window contains the same information for each rung, except for the Object Attribute field.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Communication Dialog Boxes The examples show the Communication dialog boxes for different versions of RSLogix 5000 software. The top example is for rung 0 if using RSLogix 5000, version 9 and earlier. The window is the same for each rung of this example.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Unlatch Alarms in the 1756-OF6VI Module Example rungs 5…7 show how to unlatch the following alarms in a 1756-OF6VI module: • High limit alarm - Rung 5 • Low limit alarm - Rung 6 • Ramp alarm - Rung 7 Click on the box in each rung to see the configuration and communication information. Rung 5 unlatches the high limit alarm. Rung 6 unlatches the low limit alarm. Rung 7 unlatches the ramp alarm.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Communication Dialog Boxes The examples show the Communication dialog boxes for different versions of RSLogix 5000 software. The top example is for rung 5 if using RSLogix 5000 software, version 9 and earlier. The window is the same for each rung of this example.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Reconfiguring a 1756-IR6I Module It is sometimes advantageous to change the functional operation of a module in the ControlLogix system automatically via the user program rather than using RSLogix5000 software to reconfigure it. This way, changes in the process can dictate when the reconfiguration should take place rather than you performing that function manually.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The table list module parameters that may be changed via ladder logic.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Considerations With This Ladder Logic Example IMPORTANT The considerations listed in this section apply only if you are using RSLogix 5000 software, version 9 or earlier. If you are using RSLogix 5000 software, version 10 or later, none of these considerations apply. Remember the following when using this method of module reconfiguration using the reset service.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The following ladder-logic example shows how to change the High and Low engineering values (scaling parameters) for an analog output module in Slot 3 of the local chassis. Rung Description 0 This rung moves new Channel 0 scaling parameters to the configuration portion of the structure associated with an analog output module in Slot 3 of the local chassis.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Perform Module Reset Service The following Message Configuration and Communication dialog boxes show the message instruction to perform the Reset service and its path.

Appendix E Additional Specification Information This appendix offers additional calibration information that may assist you in using the ControlLogix analog I/O module.
Appendix E Additional Specification Information Calibrated Accuracy The Calibrated Accuracy specification represents the module’s accuracy when its ambient (that is, operating) temperature is the same as the temperature at which the module was calibrated. Immediately following a calibration, a ControlLogix analog I/O module is most accurate. Because the module was calibrated at its zero and span, the inaccuracy is largely non-linearity between zero and span.
Additional Specification Information Error Calculated Over Hardware Range Appendix E A ControlLogix analog I/O module’s calibration accuracy at 25 °C (77 °F) is calculated over the full hardware range of the module and is not dependent on the application’s use of the range. The error is the same if you are measuring it across a 10% or 100% portion of a given range. However, a module’s accuracy at 25 °C (77 °F) is dependent on the hardware range in which the module operates.
Appendix E Additional Specification Information Because the specifications listed in Appendix A include a typical and worst case PPM/ °C for each module, you can determine multiple Gain Drift with Temperature values for each module. EXAMPLE For example, the 1756-IT6I module has a maximum Gain Drift with Temperature specification of 80 ppm/ °C. The 80 ppm represents 0.008% of the module’s full operating temperature.
Additional Specification Information RTD and Thermocouple Error Calculations Appendix E When you use the temperature-measuring modules (1756-IR6I, 1756-IT6I, and 1756-IT6I2), error calculations are achieved in a two-step process. 1. Calculate the module’s error in ohms or volts. 2. Convert the ohm/volt error to temperature for the specific sensor and at the correct application temperature.
Appendix E Additional Specification Information Thermocouple Error Thermocouple error at 25 °C (77 °F) indicates the module’s accuracy in measuring temperature.

Additional Specification Information Appendix E How to Deal with Incorrect Thermocouple Temperature Readings The first thought when an incorrect temperature reading is reported back in a thermocouple input module is that the module is out of calibration. This is typically not the case, particularly if the module has just been installed out-of-the-box. All thermocouple input modules are shipped factory calibrated so it is unlikely that they would need to be calibrated on installation.
Appendix E Additional Specification Information We highly recommend using a thermocouple emulator for initial troubleshooting. In lieu of an emulator, a millivolt signal can be applied to the input. To make this work, the module would have to be reconfigured to read a millivolt signal. If the module is reading back the millivolt correctly, then the module is performing as expected. Troubleshooting Checklist Check for these symptoms when troubleshooting a module. 1.
