Function

Retrieves the settings of logic of I/O control signal.

 

Format

Ret = SmcWGetCtrlInOutLog( Id, AxisNo, CtrlInOutLog )

 

Parameters

Id [ C, C++: short ] [ Python: ctypes.c_short ]

Specify the device ID retrieved by SmcWInit function.

 

AxisNo [ C, C++: short ] [ Python: ctypes.c_short ]

Specify the axis number.

 

CtrlInOutLog [ C, C++: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]

Initial Value

0 : Negative logic for all signals

 

Remarks

This function can be executed even if the device is in operation.

 

Example

The control I/O signal logic of axis number 1 is acquired.

 

C, C++

long Ret;

short CtrlInOutLog ;

Ret = SmcWGetCtrlInOutLog( Id , 1, &CtrlInOutLog );

 

Python

Ret = ctypes.c_long()

CtrlInOutLog = ctypes.c_short()

Ret.value = csmc.SmcWGetCtrlInOutLog( Id , 1, ctypes.byref(CtrlInOutLog) )
