Alarm log
NOTE:
Log principles
Alarms are stored one after another. Once the log is full, new alarms overwrite the oldest alarms.
In this way each alarm event (appearance, acknowledgment,
disappearance see section Appearance types, Page 20 ) is recorded and
time-stamped.
In order for an alarm page to be stored in the log, the store option must be enabled for the page
( see chapter C, section Page appearance types, Page 30 ).
The following functions can be executed:
- initiated by the PLC:
- print log
- clear log
- initiated by the operator:
- view log
- print log
- clear log
