Chapter 3 Module Data, Status, and Channel Configuration

Channel Configuration

Each channel is independently configured via a group of six
consecutive words in the Configuration Data file. The first two words
of the group consist of bit fields, the settings of which determine how
the channel operates. See the tables 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) Alarm interrupts are not supported by all bus masters. Check your controller’s user manual to determine if expansion I/O interrupts are supported.
(2) Do not set this bit to 1 unless the Enable Process Alarms (EA) bit is also set to 1 for the same channel.
