Properties of the alarm buffer/alarm history:
● The alarms in the alarm buffer are arranged from 7 to 0 according to the time that they
occurred. In the alarm history, this is from 8 to 63.
● If 8 alarms have been entered in the alarm buffer, and a new alarm is received, the
alarms that have been resolved are transferred to the alarm history.
● r2121 is incremented each time the alarm buffer changes.
● An alarm value (r2124) can be output for an alarm. The alarm value is used to diagnose
the alarm more accurately; please refer to the alarm description for details of the
meaning.
