7.1.1.5 Saving and Erasing the Messages
Normally, erasing the messages is not necessary because the oldest messages are
automatically erased when new events are entered, if the memory is full at the time.
However, erasure of the stored messages may be useful, for instance, after revision
of the plant, so that in the future the memory only contains information about actual
events. Erasing the memory takes place separately for each of the message groups.
