F_KinGetChnOperationState

This function returns the operating state of the kinematic channel.

Function F_KinGetChnOperationState : E_KINSTATUS

VAR_IN_OUT
    stKinRefIn : NCTOPLC_NCICHANNEL_REF
END_VAR

stKinRefIn: Determines the kinematic group of the configuration.

Return value

E_KINSTATUS: State of the kinematic channel (see below). If an invalid version of the cyclic interface is used, KinStatus_InvalidItfVersion is returned.

Sample

VAR 
    stKinRefIn AT %I*      : NCTOPLC_NCICHANNEL_REF; 
    nErrId                 : UDINT; 
    eKinOperationState     : E_KINSTATUS;
END_VAR

IF F_KinGetChnOperationState (stKinRefIn)<> KinStatus_InvalidItfVersion THEN 
    eKinOperationState := F_KinGetChnOperationState (stKinRefIn); 
ELSE 
    nErrId := F_KinGetChnOperationState (stKinRefIn);
