Configuring
Channels
After module installation, you must configure operation details, such as RTD type,
temperature units, etc., for each channel. Channel configuration data for the module is
stored in the controller configuration file, which is both readable and writable.
The configuration data file is shown below. Bit definitions are provided in Channel
Configuration, below. Detailed definitions of each of the configuration parameters
follow the table.
4.2.1 Configuration Data File
The default value of the configuration data is represented by zeros in the data file. The
structure of the channel configuration file is shown below.

The configuration file can also be modified through the control program, if supported by
the controller. For information on configuring the module using RSLogix 500 (with
MicroLogix 1500 controller), see Appendix B; for RSLogix 5000 (CompactLogix
controller), see Appendix C; for RSNetworx (1769-ADN), see Appendix D. The
structure and bit settings are shown in the section below.
