Messages
All
message events from event and alarm messages are stored automatically in
the message archive. The message archive can contain as many as 512 message
events. Message events are deleted
automatically in the case of buf
fer overflow
by means of the
Message Pr
ocessing
standard screen.
On reaching the configured remaining buffer size, (default setting 10%), an
overflow warning is issued by default. Issue of the overflow warning can be
enabled or disabled on the OP by means of the
System Settings
standard screen.

symbolic
input field and select either of the parameters
OFF
or
ON.
If the message archive is no longer capable of recording more message events,
message events are automatically deleted until the capacity configured for the
remaining buf
fer size is reached. Deletion occurs in the following sequence:
The oldest messages which have already departed.
The message events Arrived and Departed for an event message which has
departed are deleted. The message events Arrived, Departed and Acknowl
-
edged are deleted in respect of alarm messages which have been cleared.
Messages still waiting.
If the capacity is still not suf
ficient for new messages, the oldest waiting
messages are deleted. This triggers the issue of a system message.
In the case of a buf
fer overflow
, a printout of all the alarm and event messages
deleted is automatically triggered if
“Printout on overflow” is configured,
message logging is disabled on the OP and
a printer which is ready to operate is connected.
