Module Data, Status, and
Channel Configuration

After installing the 1769sc-IF4IH isolated HART 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.

This chapter contains information on the following:
