System Status
You can view system status from the Status tab of the ControlNet Hot

1785-CHBM module which is currently online.
Diagnostic Counters
Diagnostic counters provide information on the number of times the
Maximum Program Scan has exceeded the Maximum Program Scan
Time configured for the system when in Synchronous mode. These
counters are incremented by 1 every time the actual program scan is
greater than the configured program scan. The Lost Partner counter
increments every time the system has detected a loss of
communication between the primary and secondary PLC processors.
You can press the Clear button to reset these values.
Qualification Error Reason
If the qualification of the system fails, the Qualification Error Reason
indicates the reason why the failure occurred. Refer to Chapter 5 for
information on corrective actions you can take.
