Module Shutdown State and Possible Causes
Processor Module
The processor module shutdown state is the Recovery Mode. If the application was running and it has
been re-booted and the Fault Reset button pressed the module enters the Recovery Mode. Here the
System Healthy LED will stay Green for a few seconds then go Red.
Refer to the following topics:
 Recovery Mode and How it Affects Controller Operation
 Rectify a Critical Firmware/Hardware Failure
I/O Module
A module (Processor or I/O Module) is in a shutdown state indicated by the following:
Healthy: GREEN
Ready: RED
Run: RED
Note: When the module is operational and before loading an application program the module is in the
shutdown state. The module can also enter the shutdown state when the application stops running.
This is not a fault but a normal state of operation.
Possible Causes to be Investigated
However, other faults or problems such as the following can cause a module to enter this state:
 The module is not in the processor's application control; i.e. the processor has not
started the module and it stays in the shutdown state.
Check: the application program to see if the I/O module is installed in the
equipment and if so if it is installed into the correct I/O Bus and Slot.
