4.6.8.1 Alarm management manager/subordinate
Note
66 | 180
The manager receives faults and alarms from its subordinates and displays the
higher priority alarm with the subordinate identification number in the order
received. If the manager has its own faults and alarms, it displays them instead.
The subordinate sends the fault or alarm with highest priority to the manager. If the
priority of a new fault or alarm is higher than that sent, the subordinate sends the
new one to replace the original.
The table below shows error codes and default alarm texts.
