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 ªrawº data input from bus A, B, and C:

Fault contacts are set for:

HInput discrepancy faults for A, B, and C inputs

HInput autotest faults

HLine faults

See page 5-25 for detailed information on conditions that cause fault contacts to be set.

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.
