I have never seen that fault in a 330A, in a TX means:
0098 COM_Bus reconf
This section describes the Travel Control error COM_Bus reconf
During the hourly supervision period ,VCOM detected a number of communication bus reconfigurations.
This number is too high in comparison to the number of telegrams sent and received during the same one hour period.
Telegrams can be lost.Reliable operation is no longer guaranteed.
