The Alarm OR module examines up to nine Enum inputs and provides OR logic, where at least one input must be Alarm for the Alarm OR output to be Alarm. This module provides a Boolean output that indicates when all inputs are Normal, and a Boolean output that indicates when any inputs are Alarm. The module accepts eight Normal/Alarm inputs and a cascaded input for cases where you need more than eight inputs, and has outputs for any input Alarm, all inputs Normal, and an alarm output.
This module is implemented as a Control Activity.
You can view and modify the modules in this group’s logic.
