Messages

The messages are classified under four different types of event:

System (capacity for approx. 1,500 entries)

Application (capacity for approx. 4,500 entries)

Information (capacity for approx. 21,500 entries)

Warning (capacity for approx. 3,000 entries)

Messages for which an outgoing event is triggered are termed persistent indica-

tions. Persistent indications are, e.g., alarms.

Note

Each type of event is managed in its own buffer in the device. If a buffer is full, the

next message of this type overwrites the oldest message in the buffer.

The size of the information buffer is sufficient for approx. 45 days. This in an ave-

rage value based on experience. However, the message volume can vary accor-

ding to the operating conditions and plant configuration.

For further information, see Archive (Chapter 7.4).
