Module Data, Status, and Channel Configuration for the Input Module 3-7
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.
