3-22 Module Data, Status, and Channel Configuration for the Input Modules
The configuration file can also be modified through the control program, if
supported by the controller. The structure and bit settings are shown in
Channel Configuration on page 3-22.
Channel Configuration
Each channel’s configuration words consist 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.
