This number defines the nominal level of the message list after an over-
flow. After an overflow has occurred, entries in the message list are de-
leted in accordance with a positive-displacement algorithm. This is re-
peated until the level within the message list corresponds to the value
stated here.
The positive-displacement algorithm is composed of the following steps:
1) Deletion of hint messages.
2) Deletion of active, acknowledged messages. First the oldest message
is deleted and then more recent messages are deleted consecutively.
Deletion begins with priority level 4 and continues consecutively to
priority level 0.
3) Deletion of the oldest inactive, unacknowledged message. Otherwise
the same as 2).
4) Deletion of the oldest active, unacknowledged message. Otherwise
the same as 2).
Selecting Value or Long text specifies the output format of a message in
the message list at the control station.
A choice of two display formats is available for fault and switch messages:
Value Sound Priority Time Plant
Long Sound Priority Time Plant
