SmcWGetCounterMode


Function

The operation set up information of the counter is acquired.

 

Format

Ret = SmcWGetCounterMode( Id, AxisNo, ClearCntLtc, LtcMode, ClearCntClr, ClrMode )

 

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.

 

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

Specify the address of a variable to store the type of counter you want to clear when the LTC signal changes from OFF to ON.

0

Do not clear the counter

1

Clear the output pulse counter

2

Clear the encoder counter

3

Clear the output pulse counter and encoder counter

 

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

Specify the address of a variable to store the type of counter you want to latch when the LTC signal comes in.

0

Do not use latch function

1

Latch the output pulse counter

2

Latch the encoder counter

3

Latch the output pulse counter and encoder counter

 

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

Specify the address of a variable to store the type of counter you want to clear when the CLR signal changes from OFF to ON.

0

Do not clear the counter

1

Clear the output pulse counter

2

Clear the encoder counter

3

Clear the output pulse counter and encoder counter

 

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

0 fixed.

 

Return Value

Ret [ C, C++: long ] [ Python: ctypes.c_long ]

0

Terminated normally

Non-zero

Terminated abnormally

Initial Value

ClearCntLtc

0H  : Do not clear

LtcMode

0H  : Do not use

ClearCntClr

0H : Do not clear

ClrMode

0 fixed

 

Remarks

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

 

Example

The set up information of the encoder counter of axis number 1 is acquired.

 

C, C++

long Ret;

short ClearCntLtc ;

short LtcMode ;

short ClearCntClr ;

short ClrMode ;

Ret = SmcWGetCounterMode( Id , 1, &ClearCntLtc , &LtcMode , &ClearCntClr , &ClrMode );

 

Python

Ret = ctypes.c_long()

ClearCntLtc = ctypes.c_short()

LtcMode = ctypes.c_short()

ClearCntClr = ctypes.c_short()

ClrMode = ctypes.c_short()

Ret.value = csmc.SmcWGetCounterMode( Id , 1, ctypes.byref(ClearCntLtc) ,ctypes.byref(LtcMode) , ctypes.byref(ClearCntClr) , ctypes.byref(ClrMode) )
