Preface Additional Resources These documents contain additional information concerning related products from Rockwell Automation. Resource Description 1756 ControlLogix I/O Modules Specifications Technical Data, publication 1756-TD002 Provides specifications for ControlLogix I/O modules. ControlLogix Analog I/O Modules User Manual, publication 1756-UM009 Describes how to install, configure, and troubleshoot ControlLogix analog I/O modules.
Chapter 1 What is the ControlLogix High-speed Analog I/O Module? Topic Page Available Features 11 High-speed Analog I/O Modules in the ControlLogix System 12 The ControlLogix high-speed analog I/O module is an interface module that converts analog signals to digital values for inputs and converts digital values to analog signals for outputs. Using the producer/consumer network model, the module produces information when needed while providing additional system functions.
Chapter 1 What is the ControlLogix High-speed Analog I/O Module? High-speed Analog I/O Modules in the ControlLogix System A ControlLogix high-speed analog I/O module mounts in a ControlLogix chassis and uses a Removable Terminal Block (RTB) or Interface Module (IFM) to connect all field-side wiring. Before you install and use your module, do the following: • Install and ground a 1756 chassis and power supply. Refer to the publications listed in Additional Resources on page 10.
What is the ControlLogix High-speed Analog I/O Module? Chapter 1 Table 1 lists the physical features on the ControlLogix high-speed analog I/O module. Table 1 - ControlLogix High-speed Analog I/O Module Physical Features Feature Description ControlLogix backplane connector Provides an interface to the ControlLogix system by connecting the module to the backplane. Connector pins Input/output, power, and grounding connections are made to the module through these pins with the use of an RTB.
Chapter 1 What is the ControlLogix High-speed Analog I/O Module? Notes: 14 Rockwell Automation Publication 1756-UM005B-EN-P - January 2013
Chapter 2 High-speed Analog I/O Operation in the ControlLogix System Topic Page Ownership and Connections 16 Configure the Module 16 Direct Connections 17 Inputs and Outputs on the Same Module 18 Differences between Inputs and Outputs 20 Listen-only Mode 22 IMPORTANT A ControlLogix high-speed analog I/O module’s performance behavior varies depending upon whether it operates in the local chassis or in a remote chassis. Module performance is limited in a remote chassis.
Chapter 2 High-speed Analog I/O Operation in the ControlLogix System Ownership and Connections Every high-speed analog I/O module in the ControlLogix system must be owned by a ControlLogix controller. This owner-controller stores configuration data for the module and can be local or remote in reference to the module’s position. The owner-controller sends the high-speed analog I/O module configuration data to define the module’s behavior and begin operation.
High-speed Analog I/O Operation in the ControlLogix System Direct Connections Chapter 2 A direct connection is a real-time data transfer link between the controller and the module that occupies the slot that the configuration data references. When module configuration data is downloaded to an owner-controller, the controller attempts to establish a direct connection to each of the modules referenced by the data.
Chapter 2 High-speed Analog I/O Operation in the ControlLogix System Inputs and Outputs on the Same Module The ControlLogix high-speed analog I/O module has 4 inputs and 2 outputs. The following configurable parameters affect module behavior: • Real Time Sample (RTS)—Defines the input update rate. • Requested Packet Interval (RPI)—Defines the output update rate and additional transfers of input data. Real Time Sample (RTS) The RTS is a configurable parameter (0.
High-speed Analog I/O Operation in the ControlLogix System Chapter 2 Requested Packet Interval (RPI) The RPI is a configurable parameter that also instructs the module to multicast its channel and status data to the local chassis backplane. However, the RPI instructs the module to multicast the current contents of its on-board memory, including input and output data echo, when the RPI expires. When the RPI expires, the module does not update its channels prior to the multicast.
Chapter 2 High-speed Analog I/O Operation in the ControlLogix System The ControlLogix high-speed analog I/O module uses both inputs and outputs. However, there are significant differences between how each channel type operates. Differences between Inputs and Outputs Module Input Operation In traditional I/O systems, controllers poll module inputs to obtain their status. The owner-controller does not poll the ControlLogix high-speed analog inputs once a connection is established.
High-speed Analog I/O Operation in the ControlLogix System Chapter 2 Module Output Operation When specifying an RPI value for the high-speed analog I/O module, you define when the controller broadcasts output data to the module. If the module resides in the same chassis as the owner-controller, the module receives the data almost immediately. High-speed analog module outputs receive data from the owner-controller and echo output data only at the period specified in the RPI.
Chapter 2 High-speed Analog I/O Operation in the ControlLogix System Listen-only Mode Any controller in the system can listen to the data from a high-speed analog I/O module (input data or echoed output data) even if the controller does not own the module. The module does not have to hold the module’s configuration data to listen to the module. During the I/O configuration process, you can specify a Listen-only mode in the Communication Format field.
Chapter 3 Module Features Input Compatibility Topic Page Input Compatibility 23 Output Compatibility 23 General Module Features 24 Electronic Keying 25 Understand Module Resolution, Scaling and Data Format 35 Features Specific to Module Inputs 37 Features Specific to Module Outputs 46 Fault and Status Reporting 49 ControlLogix high-speed analog I/O module inputs convert the following analog signals into digital values: • Volts • Milliamps The digital value that represents the magnitude
Chapter 3 Module Features General Module Features This section describes features available on ControlLogix high-speed analog I/O modules that are common with other ControlLogix I/O modules. Removal and Insertion Under Power (RIUP) ControlLogix high-speed analog I/O modules may be inserted and removed from the chassis while power is applied.
Module Features Electronic Keying Chapter 3 The electronic keying feature automatically compares the expected module, as shown in the Logix Designer 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. For each module in the I/O Configuration tree, the user-selected keying option determines if, and how, an electronic keying check is performed.
Chapter 3 Module Features 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. If any attribute does not match precisely, I/O communication is not permitted with the module or with modules connected through it, as in the case of a communication module.
Module Features Chapter 3 Compatible Keying Compatible Keying indicates that the module determines whether to accept or reject communication. Different module families, communication adapters, and module types implement the compatibility check differently based on the family capabilities and on prior knowledge of compatible products. Release notes for individual modules indicate the specific compatibility details. Compatible Keying is the default setting.
Chapter 3 Module Features module rejecting the keying request because it is an earlier revision than the one configured in the software. EXAMPLE In this scenario, Compatible Keying prevents I/O communication. The module configuration is for a 1756-IB16D module with module revision 3.3. 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 is lower than expected and may not be compatible with 3.3.
Module Features EXAMPLE Chapter 3 In this 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 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.
Module Features EXAMPLE Chapter 3 In this 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. Module Configuration Vendor = Allen-Bradley Product Type = Digital Input Module Catalog Number = 1756-IA16 Major Revision = 2 Minor Revision = 1 Communication is allowed.
Chapter 3 Module Features Access to System Clock for Timestamping Functions Certain modules, such as controllers, in the ControlLogix chassis maintain a system clock. The clock is a free-running, 64-bit number that increments every microsecond. It is used to places a timestamp on the sampling of input data within the local chassis. You can configure your high-speed analog I/O modules to access this clock and timestamp input data when the module multicasts to the system.
Module Features Chapter 3 Status Information Each ControlLogix high-speed analog I/O module has status indicators that allow you to check module health and operational status. The following status can be checked with the indicators: • Calibration status—The display blinks to indicate when your module is in the Calibration mode. • Module status—The display indicates the module’s communication status. To see the status indicators on the ControlLogix high-speed analog I/O module, see Chapter 7.
Chapter 3 Module Features Latching of Alarms The latching feature allows the high-speed analog I/O module to latch an alarm in the set position once it has been triggered, even if the condition causing the alarm to occur disappears. Once an alarm is latched, you must unlatch it via the Logix Designer application or a message instruction. To see how to unlatch an alarm, see page 77.
Module Features Chapter 3 The following three concepts are closely related and must be explained in conjunction with each other: • Module Resolution • Scaling Understand Module Resolution, Scaling and Data Format Module Resolution Resolution is the smallest amount of change that the module can detect. High-speed analog I/O modules are capable of 14-bit resolution. The 14 bits represent 16,384 counts. Depending on the operating range, the available counts varies, as shown in Figure 4.
Chapter 3 Module Features Use Table 3 to see the resolution for each module range. Table 3 - Module Resolution Range Input Range Effective Bits across Range Resolution ±10V 0V…10V 0V…5V 0 mA…21 mA 14 bits 13 bits 12 bits 12 bits 1.3 mV/count 1.3 mV/count 1.3 mV/count 5.25 μA/count Output Range Effective Bits across Range Resolution ±10V 0 mA…21 mA 14 bits 13 bits 1.3mV/count 2.
Module Features Chapter 3 The module may operate with values beyond the 4 mA…20 mA range. If an input signal beyond the low and high signals is present at the module, such as 3 mA, that data is represented in terms of the engineering units set during scaling. Table 4 shows example values that may appear based the example mentioned previously. Table 4 - Current Values Represented in Engineering Units Features Specific to Module Inputs Current Engineering Units Value 3 mA -6.
Chapter 3 Module Features Archiving IMPORTANT Archiving is available only with the following: • Module firmware revision 3.005 or later For more information about upgrading a series A module with series B firmware, see Appendix F. • RSLogix 5000 software version 16.03.00 or later, or the Studio 5000 environment version 21.00.
Module Features Chapter 3 Enable Archiving via the Communication Format To use archiving, you must select the 1756-IF4FXOF2F/B configuration profile, and then choose the Archiving Connection communication format, as shown in Figure 6. Figure 6 - Archiving Connection Communication Format The Archiving Connection communication format creates two additional tags in the input structure of the module, as described below. Table 5 - Archiving Tags Tag Description I.
Chapter 3 Module Features Use Archiving Follow these steps to use archiving. 1. Choose a Real Time Sample (RTS) period appropriate for your application. The module supports sample periods as fast as 300 μs. However, only RSLogix 5000 software, version 18.02.00 or later, or the Studio 5000 environment, version 21.00.00 or later, lets you enter that value in the profile during module configuration. RSLogix 5000 software, version 17.01.
Module Features Chapter 3 Table 6 - Notes for Archiving Note Description 1 Setting the RPI less than the recommended value If the RPI value is less than the recommended value, archiving still works, but the module performs only a limited number of archive samples before the RPI expires. The I.LastUpdateIndex tag contains values from 0…19 to indicate the last sample number. You need to take this into account and move only some of the values returned by the module. 2 Using the I.
Chapter 3 Module Features Multiple Input Ranges You can select from a series of operational ranges for each input channel on your module. The range designates the minimum and maximum signals that the module can report. The following input ranges are available on the high-speed analog I/O module: • -10…10V • 0…5V • 0…10V • 0…20 mA For an example of how to choose an input range for your module, see page 77.
Module Features Chapter 3 Digital Filter The digital filter smooths input data noise transients for all input channels on the module. This feature is used 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 0.0 disables the filter. The digital filter equation is a classic first order lag equation.
Chapter 3 Module Features Process Alarms Process alarms (configured in engineering units) alert you when the module has exceeded configured high or low limits for each input channel. You can latch process alarms. These are set at four user configurable alarm trigger points: • High high • High • Low • Low low You can configure an alarm deadband to work with these alarms.
Module Features Chapter 3 Rate Alarm The rate alarm triggers if the rate of change between input samples for each input channel exceeds the specified trigger point for that channel. Values are configured in volts/second (V/s). EXAMPLE If you set the module to a rate alarm of 10.0V/s, the rate alarm will only trigger if the difference between measured input samples changes at a rate greater than 10.0V/s.
Chapter 3 Module Features The initial sample is delayed to synchronize with other modules, but then each module samples its input channels at the appropriate RTS interval. For example, the first sample is delayed to synchronize with the sampling of the other modules. The delay is 1 to 2 RTS worth of time. If you use an RTS = 10 ms, the first sample delays an extra 10…20 ms to achieve synchronization.
Module Features Chapter 3 Ramping/Rate Limiting Ramping limits the speed at which 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. Ramping is possible in the following situations: • Run mode ramping—Occurs during Run mode and begins operation at the configured maximum ramp rate when the module receives a new output level.
Chapter 3 Module Features Clamping/Limiting Clamping limits the data from an output so that it remains in a range configured by the controller, even when the controller commands an output outside that range. This safety feature sets a high clamp and a low clamp. Clamping alarms can be disabled or latched on a per channel basis.
Module Features Fault and Status Reporting Chapter 3 The ControlLogix high-speed analog I/O module multicasts status/fault data to the owner/listening controller with its channel data. The fault data is arranged so that users can choose the level of granularity they desire for examining fault conditions. Three levels of tags work together to provide an increasing degree of detail as to the specific cause of faults on the module: · Module Fault word—Provides fault summary reporting.
Chapter 3 Module Features Fault Reporting Example Figure 10 shows an example of what bits are set when a ControlLogix high-speed analog I/O module reports a Wire Off condition on output channel 0. Three events occur, beginning in the Output Channel Status word. Figure 10 - Fault Reporting for Wire Off Condition 15 14 13 12 11 When set, the I.Out0Fault bit (bit 4) sets the I.OutGroupFault bit (bit 13) and the I.AnalogGroupFault bit (bit 15). 5 4 3 2 1 0 When set, I.Out[0].WireOff bit sets the I.
Module Features Chapter 3 Channel Fault Word Bits Table 9 defines the Channel Fault word bits. Table 9 - Channel Fault Word Bit Descriptions Bit Name Description Bit 5 I.Out1Fault Bit is set if any of the following events occurs: • The module is being calibrated. • A communication fault occurs between the module and its owner-controller. • Wire off condition exists on output channel 1. • Low limit alarm is set on output channel 1. • High limit alarm is set on output channel 1. Bit 4 I.
Chapter 3 Module Features Input Channel Status Word Bits Table 10 defines the Input Channel Status word bits. Table 10 - Input Channel Status Word Bit Description 52 Bit Name Description Bit 8 I.In[x].ChanFault This bit matches the state of I.InxFault bits (0-3) in the Channel Fault word, except when a communication fault occurs. If a communication fault occurs between the module and its owner-controller, the I.InxFault bit is set but this bit is not set.
Module Features Chapter 3 Output Channel Status Word Bits Table 11 defines the Output Channel Status word bits. Table 11 - Output Channel Status Word Bit Descriptions Bit Name Description Bit 8 I.Out[x].ChanFault This bit matches the state of I.OutxFault bits (4 & 5) in the Channel Fault word, except when a communication fault occurs. If a communication fault occurs between the module and its owner-controller, the I.OutxFault bit is set but this bit is not set.

Chapter 6 Calibrate the Module Topic Page Differences for Each Channel Type 86 Calibrate Input Channels 87 Calibrate Output Channels 90 Your ControlLogix high-speed analog I/O module comes from the factory with a default calibration. Use this chapter to recalibrate your module in the future. You must add the module to your control program via the Logix Designer application. Also, if you want to calibrate the module outputs, you must configure an output range before calibrating the module.
Chapter 6 Calibrate the Module Differences for Each Channel Type The procedures for calibrating input and output channels on the ControlLogix high-speed analog I/O module vary slightly: • For input channels, you use a voltage calibrator to send a signal to the module to calibrate it. • For output channels, you use a digital multimeter (DMM) to measure the signal the module is sending out. See the recommended instruments to use for each channel below.
Calibrate the Module Calibrate Input Channels Chapter 6 Input calibration requires that you apply reference signals to the module’s input channels and then verify the channel status. ControlLogix high-speed analog I/O modules can operate in Current or Voltage mode. For voltage applications, you need to calibrate only the -10…10V range. Calibrating to this range calibrates the module for all other voltage ranges, such as 0…5V.
Chapter 6 Calibrate the Module The Module Properties dialog box appears. Click the Input Calibration tab. 3. On the Input Calibration page, begin calibration. Click here to start calibration. The software warns you not to calibrate a module currently being used for control. Click OK to continue calibration. 4. Set the channels to be calibrated. Choose the channel you want to calibrate. Choose whether you want to calibrate channels in groups or one at a time. Click Next to continue.
Calibrate the Module Chapter 6 The low reference parameters appear first. These parameters define which channels will be calibrated for a low reference. Click Back to return to the previous parameters and make any necessary changes. Click Next to calibrate the low reference. 5. Apply the calibrator’s low reference to the module. The following example shows the channel status after calibrating for a low reference. If the channels is OK, continue, as shown below.
Chapter 6 Calibrate the Module 6. Apply the calibrator’s high reference to the module. The following example shows the channel status after calibrating for a high reference. If the channels is OK, continue, as shown below. If any channels report an Error, retry until the status is OK. Click Next to calibrate the high reference. The following parameters appear next and define the status of the low and high calibration. Click Finish to complete calibration for the channel.
Calibrate the Module Chapter 6 To calibrate the high-speed analog module’s outputs, follow these steps. 1. Connect your current or voltage meter (depending on what mode your channel is operating in) to the module. Remember, that you must wire the module differently for Current mode than for Voltage mode. To see how to wire for each mode, see page 63. 2. Access the module’s properties page. Right-click I/O Configuration to see the menu. Choose Properties. The Module Properties dialog box appears.
Chapter 6 Calibrate the Module 3. Verify the operating range for each channel. You must use the correct operating range for each channel being calibrated or calibration will not work. For example, if you want to calibrate channel 0 in Voltage mode, it must be set for the -10…10V range. 4. Go to the Output Calibration page to begin calibration. Choose the channel. Make sure each channel is using the correct operating range. If the operating range is incorrect, use the pull-down menu to change the range.
Calibrate the Module Chapter 6 6. Command the output channel to produce a low voltage reference level. The software commands the output channel 0 to produce a low voltage reference of 0.00V. Click Next to proceed. 7. Record the voltage measurement shown on your voltage calibrator. We recommend you use a minimum of four digits beyond the decimal point. Click Next to proceed.
Chapter 6 Calibrate the Module If the measurement is within an acceptable range, the channel is marked with an OK status, such as shown below. If the measurement is not within an acceptable range, the software returns you to step 6 until the module produces an acceptable output low reference level. 0.0021 Click Next to proceed. 8. Command the output channel to produce a high voltage reference level. The software commands the output channel 0 to produce a high voltage reference of 10.00V.
Calibrate the Module Chapter 6 If the measurement is within an acceptable range, the channel is marked with an OK status, such as shown below. If the measurement is not within an acceptable range, the software returns you to step 8 until the module produces an acceptable output low reference level. Click Next to continue. 10. Repeat step 6 through step 9 to calibrate output channel 1 for 0…20 mA operation. When you have successfully calibrated both channels, the following parameters appear.

Appendix A Data Storage Topic Page Timing Relationships 101 Choose a Communication Format 102 Use an Event Task to Store Module Data 104 You can store module data in controller tags by using an Event task. Timing Relationships This section describes the timing relationship between the module’s RPI, RTS, and an Event task with a Module Input Data State Change trigger. This type of Event task monitors a module’s input data and is triggered each time the input data changes.
Appendix A Data Storage Remote Module Considerations If the 1756-IF4FXOF2F module is not in the same chassis as its owner-controller, the following considerations apply: • Update rates can be slower for network interface cards and network bandwidth, especially with faster RTS rates, such as less than 4 ms. • If the remote module is on a ControlNet network, the modules still retrieves channel input data at the RTS rate, but the module produces data on the network only at the RPI rate.
Data Storage Appendix A If you choose the Archiving Connection communication format, you receive up to 20 analog samples per update, but you receive only one CST timestamp per module update. With an archiving connection, the CST timestamp is associated with the .LastUpdateIndex sample. In a typical case, the LastUpdateIndex value is equal to 19, .Input[19] is the newest sample, and the timestamp is associated with sample Input[19].
Appendix A Data Storage Use an Event Task to Store Module Data This example shows how to store module data in controller tags by using the following process. 1. The module retrieves channel data. 2. The module sends the updated channel data to the controller. 3. The updated channel data triggers an Event task. 4. Event task logic stores the channel data in controller tags. To configure the data storage process described above, follow these steps. 1.
Data Storage Appendix A 2. Enter the RPI and RTS values for your application. Be aware that as these values decrease, the Event task executes more frequently, and the module sends data to the controller at a faster rate. This places more demand on controller resources. For example, an RTS of 4 ms causes the Event task to trigger every 4 ms.
Appendix A Data Storage 3. Create an Event task with the values shown below. For all other fields, specify values that are specific to your application. Field Value Type Choose Event. Trigger Choose Module Input Data State Change. Tag Choose the controller input tag for the 1756-IF4XOF2F module. 4. Create a user-defined data type to store the data. The data type size varies by application. In this example, the data type stores 100 data samples.
Data Storage Appendix A 5. Create a tag to the store the data: • The data type for the tag must be the user-defined data type you created in step 4. • Because the data type in this example stores 100 data samples, the new tag maintains a 100-word circular buffer of the rolling and CST timestamps. You can monitor either of the timestamps to compare data samples from one scan to the next.
Appendix A Data Storage 6. Create application logic for the Event task you created in step 3. The ladder logic below is an example of the type of logic you can use for the Event task. Create logic that is specific to your application.

Appendix E Module Operation in a Remote Chassis The timing of this reserved spot may or may not coincide with the exact value of the RPI, but the control system guarantees that the owner-controller receives data at least as often as the specified RPI. Figure 16 - Owner-controller Receives Input Data from Remote Chassis Owner-controller ControlNet Communication Module ControlNet Communication Module High-speed Analog I/O Module Input data in remote chassis at the RTS and RPI rates.
Module Operation in a Remote Chassis Appendix E When an RPI value is specified for a module in a remote chassis, in addition to instructing the controller to multicast the output data within its own chassis, the RPI also reserves a spot in the stream of data flowing across the ControlNet network. The timing of this reserved spot may or may not coincide with the exact value of the RPI, but the control system guarantees that the output module receives data at least as often as the specified RPI.
Appendix E Module Operation in a Remote Chassis 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 data is not received by the module until the next scheduled network slot. IMPORTANT Use RSNetWorx Software and Logix Designer Application 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.
Module Operation in a Remote Chassis Configure High-speed Analog I/O Modules in a Remote Chassis Appendix E ControlLogix ControlNet interface modules (catalog numbers 1756-CNB or 1756-CNBR) are required to communicate with a ControlLogix high-speed analog I/O module in a remote chassis. You must configure the communication module in the local chassis and the remote chassis before adding new high-speed analog I/O modules.
