Function (FC): Alarm Bit Map - v2.0

This function is used to map alarm bits into an integer variable in abstractAlarmLevel.

_objectContainer
└─ alarm
   ├─ level # USINT
   │
   ├─ a?? # STRUCT
   │  ├─ triggered # UINT
   │  ├─ id # UINT
   │  ├─ map # Array[n] of INT  ← _alarmBitMap() updates this variable
   │  ├─ a00_name # BOOL → _alarmBitMap() reads this variable
   │  ├─ a01_name # BOOL → _alarmBitMap() reads this variable

Use cases

• Used to map alarm bits into an integer. Useful for legacy HMI or SCADA that do not support bits.
