FB_BA_EventObjectEx

The function block FB_BA_EventObjectEx extends the basic functionalities of a BACnet object by the property object internal notification (Intrinsic Reporting). Here, notifications and alarm messages are generated by the BACnet object itself and forwarded to a notification class.

In addition, the object is extended by the property of a time delay (stTimeDelay) of the event processing (eEnPlantLock).

E_BA_LockPriority

The enumeration can be used to parameterize various switching actions related to the event of an object.

In the event of a fire damper malfunction, for example, it may be necessary to shut down the associated ventilation system (see PlantLock).

stTimeDelay

ST_BA_TimeDelayParam

The structure can be used to delay the object's event algorithm for the TO_OFFNORMAL and TO_NORMAL state change.

In the standard PLC PLC BA-Template is the list BA2_Param.

In it, the delay times for TO_OFFNORMAL and TO_NORMAL are pre-initialized with one second each by means of the two variables nDefTimeDelay_ToAbnormal and nDefTimeDelay_ToNormal.
