Module Data, Status, and
Channel Configuration
After installing the 1769sc-OF4IH isolated HART output 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:
 Module memory map
 Accessing input image file data
 Configuring channels
 Determining effective resolution and range
 Determining module update time
