bError         : BOOL;
nErrorId       : UINT;

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.

nPresentValue: Current value of the BACnet object (see also BACnet specification DIN EN ISO 16484-5 for BACnet object Accumulator and property Present_value).

nMaxPV: Current value of the property Max_Pres_Value of the BACnet object (see also BACnet specification DIN EN ISO 16484-5 for BACnet object Accumulator and property Max_Pres_Value).

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

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

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

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

RemoteDevice       : FB_BACnet_RemoteDevice;

RemoteDevice: Specification of the instance of the corresponding remote BACnet server block (client). A BACnet adapter can be used for several BACnet clients. See FB_BACnet_Adapter and FB_BACnet_RemoteDevice for further information.
