ItpIsFastMFunc

ItpIsFastMFunc is a function that determines whether the fast M-function is set for the supplied M-function number.

VAR_IN

FUNCTION ItpIsFastMFunc

VAR_IN
    nFastMFuncNo   : INT;
END_VAR

nFastMFuncNo: Number of the M-function that is to be checked.

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 the fast bit of the M-function is set.

	ItpIsFastMFunc evaluates the variable 'nFastMFuncMask' from the cyclic interface.

Sample

(*this enum is defined by the user *) 

TYPE FastMFuncs: 
(
    M10_CoolingFluidOn := 10, (*fast M-Funktion M10*)
    M11_CoolingFluidOff := 11,
    M12_FanOn := 12,
    M13_FanOff := 13
);
END_TYPE

VAR
    sNciToPlc AT%I*: NCTOPLC_NCICHANNEL_REF
    enFastMFuncs   : FastMFuncs;
     bTurnFanOn    : BOOL;
END_VAR

bTurnFanOn := ItpIsFastMFunc( M12_FanOn,sNciToPlc );
