DIA_MAINTENANCE
Maintenance required
You have changed the
PROFIBUS identification number
parameter during the active
cyclic operation. The device
reports the identification number
violation and displays a failure
warning. In case of a warm
restart, the device will no longer
participate in the cyclic transfer
of useful data without changing
the system configuration.
Depends on the
triggering
diagnostics event.
