The messages are divided into four different event types:
• System (capacity for approx. 1500 entries)
• Application (capacity for approx. 4500 entries)
• Information (capacity for approx. 21500 entries)
• Warning (capacity for approx. 3000 entries)
Messages for which a going event is also triggered, are called persistent mes-
sages. Persistent messages are, for example, alarms.
For further information, see also Archive (Section 7.4).
Note
Each event type is managed in the device in a separate buffer. When a buffer is
full, the next message of this type overwrites the oldest message in the buffer.
The buffer for information is sufficient for approx. 45 days of operation. This is an
average empirical value. Depending on the operating conditions and plant config-
uration, the number of messages can differ from this value.
