3.7.3. Alarm, Warning & Manipulation Events
The event recorder acquires the alarms as they appear on the alarm
relays. Meaning after a pick up and with a hold time.
The alarm entry in the event recorder listing is “PLC link alarm” or
“PLC link alarm cleared” for example. In order to distinguish between
two teleprotection equipment TPE1 and TPE2, the corresponding
number is added (i.e. “TPE1 hardware alarm”).
The following events of the local device are recorded as alarm &
manipulation events:
• Start time, end time and time of a change in any PLC low level
alarm or warning
• Start time, end time and time of a change in any DATA low level
alarm or warning
