Discrete Input Fault Contacts for GMR
In the discrete Input Table there are fault contacts associated with each item of voted
input data, non-voted input data, and “raw” data input from bus A, B, and C:

Discrete Output Fault Contacts for GMR
For discrete outputs, fault contacts are associated with logical outputs (outputs from the
application program). These logical references are copied to the physical output references. If
a fault is detected on a physical output, the fault contact associated with that output’s logical
reference is set.
