F_Bool_To_BinPV : E_BACNETBINARYPV
Application
Function for implementing a value with data type BOOL of the PLC in the process data value of a BACnet binary* object / property Present_Value. This function can be used to write BACnet binary* objects, for example, which are only linked to a BACnet object via a primitive PLC variable (e.g.
bBV0 AT%Q* : E_BACnetBinaryPV; (* ~(BACnet_ObjectType : BV : NOLINK)(BACnet_ObjectIdentifier : 0 : NOLINK)(BACnet_PresentValue_Priority12 : : LINK) *)
).
The following table shows the logic:
bEnable | bNull | bBool |
| Return value |
|---|---|---|---|---|
FALSE | - | - | → | NOTHING |
TRUE | TRUE | - | → | NULL |
TRUE | FALSE | FALSE | → | INACTIVE |
TRUE | FALSE | TRUE | → | ACTIVE |
VAR_INPUT
bEnable : BOOL;
bNull : BOOL;
bBool : BOOL;
bEnable: TRUE = The process data is enabled; the value resulting from bNull or bValue 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 bValue
bBool: Value that is written to the BACnet object, if bEnable = TRUE and bNull = FALSE.
Return value: Function result of type E_BACNETBINARYPV.
