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.
