FB_BA_BuildingLighting

This template compiles cross-building control telegrams for the light functions.

The "fire" and "burglary" alarms are usually recorded in the building controller (FB_BA_FireAlarmSystem and FB_BA_BurglarAlarmSystem). From there, they are sent with other information via the communication server (FB_BA_AdsComServer_Basic) to the floor controllers, where they are received in the counter-block FB_BA_AdsComClient_Basic and made available centrally in the local variable list Site.

The fire and burglary alarms can each trigger a separate light telegram via the FireAlert and Burglary Event function blocks. The telegrams are routed to a priority function block PrioSwi.

In addition to the alarms, a global reset of the light functions is provided in this template. On the one hand, it consists of manual triggering via a GlobalReset input object, which is parameterized in FB_Init as a push button and on the other hand, a trigger signal is generated when the building energy level "Protection" or "Economy" is reached, which is intended to signal "Absence".

The resulting light telegram from PrioSwi and the global reset "Light" are made available via the stBuildingLighting structure in the local variable list Site.

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