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 turns 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 turns 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.
It is possible during sustained periods of abnormal field voltage and/or
current slewing for channels to be declared faulted as a consequence of
diagnostics that are otherwise designed to verify the channels are operating
within their designed safety accuracy. For details of slew rate limitations, refer
to the 1715 Redundant I/O System Specifications Technical Data, publication
