Module Data, Status, and Channel Configuration Chapter 3
Alarm Deadbands
The module checks for an alarm deadband value that is less than 0 or
large enough to be equal to or exceed one-half of the difference
between the high alarm and low alarm values. When one of these
conditions occurs, a module configuration fault results.
Output Channel
Configuration Each output channel is independently configured via a group of eight
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 output 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) Alternate output states are not supported by all controllers. Refer to your controller’s user manual to determine whether alternate output states and this module function
are supported.
(2) Module interrupts are not supported by all controllers. Refer to your controller’s user manual to determine whether module interrupts are supported.
