Configure ControlLogix Analog I/O Modules Chapter 7
Connection Type
The communication format determines the following for the module type
you configure:
• Available configuration parameters
• Data type that is transferred between the module and the controller
• Which tags are generated when configuration is complete
The following table describes connection formats used with analog I/O modules.
Edit the Configuration
You use the tabs in the New Module dialog box to edit module configuration.
Some tabs show the same fields regardless of the module type you are
configuring, and other tabs show fields specific to the module type.
The following tabs show the same fields regardless of module type. These tabs are
not shown in this section:
• General (described beginning on page 127
)
• Connection
• Module Info
• Time Sync
The following tabs show fields specific to the module type:
• Configuration
• Calibration
• Alarm Configuration - Available with only the 1756-IF8I and
1756-IRT8I modules.
• CJ Configuration - Available with only the 1756-IRT8I and 1756-IT16
module.
• Limit Configuration - Available with only the 1756-OF8I module.
Connection Type Definition
Input Data All available configuration, input and output data. This connection type creates all of the
appropriate controller tags for the module type being used. For example, tags specific to a
channel on the 1756-IRT8I module using the RTD input type are different from those specific
to a channel on the same module using the thermocouple input type.
Listen-only Controller and module establish communication without the controller sending any
configuration or output data to the module. A full input data connection is established but is
dependent on the owner-controller’s connection.
