AxisIsCoupled
AxisIsCoupled evaluates the coupling state of the cyclic axis interface between the NC and the PLC. AxisIsCoupled returns TRUE if nCoupleState > 1. This means that the axis is coupled to a master axis as a slave axis.
FUNCTION AxisIsCoupled: BOOL
VAR_INPUT
nCoupleState : DWORD;
END_VAR
nStateDWord : Status word from the cyclic axis interface from the NC to the PLC
Example
PROGRAM MAIN
VAR
PlcToNc1 AT %QB1000 : PLCTONC_AXLESTRUCT;
NcToPlc1 AT %IB1000 : NCTOPLC_AXLESTRUCT;
Coupled : BOOL;
END_VAR
Coupled := AxisIsCoupled( NcToPlc1.nCoupleState );
