bReady: Notification of general readiness. If this output is set, the other status outputs are valid (PresentValue, Overridden ...). If the output is FALSE, the corresponding function block FB_BACnet_Device does not report "Operational", or the block instance was not linked correctly in the TwinCAT System Manager.

bPresentValue: Current value of the BACnet object (see also BACnet specification DIN EN ISO 16484-5 for BACnet object BinaryInput and property Present_Value).

bOverridden, bOutOfService, bFault, bInAlarm: See BACnet specification DIN EN ISO 16484-5 for BACnet object BinaryInput and property Status_Flags.

bNoSensor, bOpenLoop, bShortedLoop, bOtherFault: See BACnet specification DIN EN ISO 16484-5 for BACnet object BinaryInput and property Reliability.

eEventState: See BACnet specification DIN EN ISO 16484-5 for BACnet object BinaryInput and property Event_State.

bAckedTrans_ToOffNormal, bAckedTrans_ToFault, bAckedTrans_ToNormal: Flags of property Acked_Transitions (see BACnet specification DIN EN ISO 16484-5 for BACnet object BinaryInput and property Acked_Transitions).

nChangeOfState: Number of changes of state (not to be confused with changes in value) of the property Present_Value (see BACnet specification DIN EN ISO 16484-5 for BACnet object BinaryInput and property Change_Of_State_Count).

tObjectID: Object ID of the BACnet object (object type and object instance).

bError: An error is pending.

nErrorId: see global constants (BACnet_Globals).

VAR_IN_OUT

Device               : FB_BACnet_Device;

Device: Specification of the instance of the local corresponding BACnet server block. For each BACnet adapter one BACnet server is possible. See FB_BACnet_Adapter and FB_BACnet_Device for further information.
