ItpIsHskMFunc

ItpIsHskMFunc 1:

ItpIsHskMFunc determines whether an M-function of type handshake is present.

VAR_IN_OUT

VAR_IN_OUT
    sNciToPlc           : NCTOPLC_NCICHANNEL_REF;
END_VAR

sNciToPlc: The structure of the cyclic channel interface from the NCI to the PLC. This structure is only accessed for reading. (type: NCTOPLC_NCICHANNEL_REF)

Return value

The function returns TRUE if an M-function of type handshake is present.

ItpIsHskMFunc 2:

ItpIsHskFunc evaluates the variable 'nHskMFuncReq' from the cyclic interface.

Sample

VAR
    bMFuncRequest   : BOOL;
    sNciToPlc AT%I* : NCTOPLC_NCICHANNEL_REF;
END_VAR
bMFuncRequest := ItpIsHskMFunc( sNciToPlc );
