Status Indicators
The front panel module status indicators report general status and fault status.
Faults can also be reported via the user application, sourced from system variables
or I/O connection points. Faults are classified as listed here:
• System faults
• Module faults
• Channel faults
• Field Faults
Faults
Faults are described here.
System Faults
If redundant adapters are fitted, then the Rack Status indicator on both adapters
simultaneously turn RED.
A system fault is indicated when a fault is detected on any module (including the
adapter) or any channel. When this type of fault occurs in the system, the Rack
Status indicator on the adapters turn red.
Module Faults
A module fault is indicated when a detected fault is isolated to the hardware of a
specific module. The Module Status indicator turns RED on the faulty module
and then the Rack Status indicator on the adapter turns RED.
