Module Data, Status, and Channel Configuration for the Input Modules 3-5
Channel Configuration
Each channel configuration word consists of bit fields, the settings of which
determine how the channel operates. See the table below and the descriptions
that follow for valid configuration settings and their meanings. The default bit
status of the configuration file is all zeros.

(1) 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.
(2) If reserved bits are not equal to zero, a configuration error occurs.
(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.
