Module Data, Status, and
Channel Configuration
After installing the 1769sc-IT6I Isolated Thermocouple/mV Input Module, you
must configure it for operation, usually using the programming software
compatible with the controller (for example, RSLogix 500 or RSLogix 5000).
Once configuration is complete and reflected in the ladder logic, you need to
operate the module and verify its configuration.
