4-6 Module Data, Status, and Channel Configuration for the Output Modules
1769-OF2 Channel Configuration
Both channel configuration words (0 and 1) consist of bit fields, the settings of
which determine how the corresponding channel operates. See the table below
and the descriptions that follow for valid configuration settings and their
meanings.

If reserved bits are not equal to zero, a configuration error occurs.
(2)
Any attempt to write a non-valid (not used) bit configuration into any selection field results in a module configuration error. See Configuration Errors on page 5-6.
(3)
This range is applicable to the PID function of the MicroLogix 1500 packaged controller, PLC, or SLC controllers. Logix controllers can use this or one of the other ranges for
their PID functions.
