Fatal Errors
Fatal errors occur when the firmware on the module encounters an
unexpected condition. There are three main causes for fatal errors:
• A bug in the 1756-RIO module firmware
• A 1756-RIO module hardware failure
• Certain types of ControlLogix backplane failures
The 1756-RIO module monitors its own operation for invalid conditions. The
module stops scanning, turns all three status indicators red and displays a fatal
error number similar to ‘M#60’ on the 4-character display, and then stores a
fatal error log that indicates the cause of the fatal error.
