Chapter 7 Monitoring the 1757-ABRIO Module
The rack diagnostic counters consist of the following counters for
each partial rack.
Fatal Errors Fatal errors occur when the firmware on the module encounters an
unexpected condition. The module stops scanning, turns all three
status indicators red, displays the fatal error number on the 4-character
display, and stores a fatal error log that indicates the cause of the fatal
error.
To clear the fatal error and capture the fatal error log:
1. Cycle power to the module.
The 4-character display should show “FatalErrorCapture
required”.
2. Start AbRioCfg software.
3. Select Tools>Fatal Error Capture.
4. Store the fatal error log to a file.
This also clears the fatal error on the module.
5. Contact Rockwell Automation Technical Support and provide
them with the fatal error log, which will help diagnose the cause
of the problem.
Clearing fatal errors also clears the configuration on the module. After
you clear the fatal error, download the configuration to the module
using AbRioCfg software.
Rack Diagnostic Counters
Counter Description
Rx This counter increments when the 1757-ABRIO module receives a
packet from this rack.
Crc This counter increments when the 1757-ABRIO module receives a
packet with a bad CRC from this rack.
Tout This counter increments when the 1757-ABRIO module sends a packet
to this rack and does not receive a reply within the time-out period.
Prtcl This counter increments when the 1757-ABRIO module receives a
packet from this rack that does not make sense in terms of the
protocol.
