FB_BACnet_RemoteMultiStateOutput_EX

FB_BACnet_RemoteMultiStateOutput_EX 1:

Application

The function block FB_BACnet_RemoteMultiStateOutput_EX can be used for read and write access to a BACnet object of type MultiStateOutput.

VAR_INPUT

Notice: Variables shown in red are not included in the basic version of the function block, but in the _WR version.

bEnablePV      : BOOL;
bNullPV        : BOOL;
nPV            : UDINT;

bEnable: TRUE = The process data is enabled; the value resulting from bNull or nState is written to the corresponding BACnet object, FALSE = process data is disabled

bNull: TRUE = zero writing of the BACnet object (e.g. for deleting a priority), FALSE = write value from nState

nPV: Value that is written to the BACnet object, if bEnable = TRUE and bNull = FALSE. Multi-State in the range [1 .. Number_Of_States].

VAR_OUPUT

bReady         : BOOL;
nPresentValue  : UDINT;
bOverridden    : BOOL;
bOutOfService  : BOOL;
bFault         : BOOL;
bInAlarm       : BOOL;
bNoOutput      : BOOL;
bOpenLoop      : BOOL;
bShortedLoop   : BOOL;
bOtherFault    : BOOL;
eEventState    : E_BACNETEVENTSTATE;
nActivePrio    : UINT;
nNbrOfStates   : UDINT;
tObjectID      : T_BACnet_ObjectIdentifier:=16#FFFFFFFF;
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 MultiStateOutput and property Present_value).

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

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

eEventState: E_BACNETEVENTSTATE, see BACnet specification DIN EN ISO 16484-5 for BACnet object MultiStateOutput 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 MultiStateOutput and property Acked_Transitions).

nActivePrio: Indicates the currently active priority of the priority array, which acts on the Present_Value (see also BACnet specification DIN EN ISO 16484-5 for BACnet object MultiStateOutput and property Present_Value).

nNbrOfStates: Reports the available number of values, which the Present_Value of the MultiStateInput object can assume (1...nNbrOfStates). If nNbrOfStates is 0, then there is no valid "state" which the object can assume (Present_Value is 0).

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.
