Connection Shutdown Discrepancy Error - Input Group 1

What does FB CONNECTION SHUTDOWN Bit 0 mean?

A discrepancy has been detected in input group 1 for the FB CONNECTION SHUTDOWN. This means the redundant input signals ('DeactivateX TRUE') are not in agreement, which prevents the Connection Shutdown function from reliably commanding a SHUTDOWN state or detecting it from the assigned Connection. This poses a risk to controlled deactivation and will stop the machine.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review the discrepancy time parameter for input group 1 in the FB CONNECTION SHUTDOWN configuration; adjust if application-specific timing requires it.

2. 4

   Monitor the individual input channels for group 1 in real-time using diagnostics to identify which channel is deviating or delayed.
