FB_BA_AC_OpMod1St

The template represents the operation mode of an air conditioning system.

The priority switch PrioSwiOpMod prioritizes various events or commands such as fire alarms, requests from the time schedule or requests from the plant selector switch and writes a resulting operation mode or system status to the variable eOpMode.

The initialization of the template takes place within the method FB_Init.
