Skip Communication Error Station - Panasonic GTWIN Reference Manual

GTWIN Reference Manual

1.6.3.1 Skip Communication Error Station

If this function is not activated, communication within a chain of multiple PLCs collapses and a
communication error occurs if a PLC becomes disconnected or its power fails.
By activating this function, communication will bypass the defective PLC and continue with the
other PLCs.
Once you activate "Skip Communication Error Station", you can poll the PLC to check whether
the communication error has been recovered. Click [Setup] to call up the dialog.
The GT polls the defective PLC at the Confirmation Interval specified to see whether the
communication error has been recovered. During polling, the PLC must respond during the
specified Timeout. If the communication error has been recovered, communication is
resumed. Otherwise the PLC is skipped until the next confirmation interval.

During the timeout, the GT panel cannot be operated.

Frequent confirmation intervals and long timeouts will compromise system
availability.
