Function (FC): 1 Alarm Bit ID - v2.0

This function is used to load the triggered alarm ID into abstractAlarmLevel. This function is part of a set of functions that allow managing multiple alarm bits, each with a different number of alarm IDs.

See the following functions to manage different numbers of alarms:

_alarmBit02Id() for managing 2 alarms.
_alarmBit04Id() for managing 4 alarms.
_alarmBit08Id() for managing 8 alarms.
_alarmBit16Id() for managing 16 alarms.

If you need to manage a different number of alarms, you can chain multiple of these functions. For example, to manage 3 alarms you can use:

_alarmBit01Id(), _alarmBit01Id() and _alarmBit01Id().
_alarmBit01Id() and _alarmBit02Id().
_alarmBit02Id() and _alarmBit02Id().
_alarmBit04Id().

Use cases
