for the bit associated with the module in rack 1 slot 4.
Use the aliases to access the status bits.
TIP
If the ControlLogix loses communication with the QTS-CLX-APACS, it
sets the first four bytes of connection 0 to FF hexadecimal (11111111
binary).
Monitor these four bytes to determine if there is a problem.
Fatal Errors
Fatal errors occur when the firmware on the module encounters an unexpected condition.
The module stops running, turns all three LEDs red, and displays the fatal error number
on the 4-character display. The module also records its state at the time the fatal error
occurred in a log.
To clear the fatal error and capture the fatal error log:
1. Cycle power on the module. The 4-character display should show
“FatalErrorCapture required”.
2. Run the utility FatalCapt.exe from the subdirectory Tools where you installed
the configuration tool.
3. Store the fatal error log to a file. This also clears the fatal error on the
module.
Contact technical support. Provide them with the fatal error log, which will help
diagnose the cause of the problem.
