CntStopCount

Function

Stops the count operation of specified channel. Supports multi-processing.

Format

Ret = CntStopCount ( Id , ChNo , ChNum )

Parameters

Id [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved from CntInit.

ChNo [ VB.NET: Short ] [ C, C++: short * ] [ C#: out short ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specify the base address of array storing the stopping channel number.

ChNum [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the number of channels in array ChNo.

Return Value

Ret [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

Definition	Value	Description
CNT_ERR_SUCCESS	0	Normality completion
CNT_ERR_SYS_RECOVERED_FROM_STANDBY	7	Execute the function CntResetDevice to return from the standby mode.
CNT_ERR_DLL_INVALID_ID	10001	Invalid ID was specified.
CNT_ERR_DLL_CALL_DRIVER	10002	CNT driver can't be called (Failed in the device I/O control).
CNT_ERR_DLL_BUFF_ADDRESS	10101	Invalid data buffer address.
CNT_ERR_SYS_BOARD_EXECUTING	20002	Cannot use while by another device works.
CNT_ERR_SYS_CH_NO	20201	Channel number is out of range.
CNT_ERR_SYS_CH_NUM	20202	Number of channels is out of range.

Initial Value

None

Remarks

Stops the count operation of specified channel. Passes channel number in array.
For board CNT24-4D(PCI)H, the count value is cleared to zero when this function is executed.

Example

Stops the count operation of channel 0 and 1.

VB.NET	Dim Ret As Integer Dim ChNo(1) As Short ChNo(0) = 0 ChNo(1) = 1 Ret = CntStopCount( Id , ChNo , 2 )
C, C++	long Ret; short ChNo[2]; ChNo[0] = 0; ChNo[1] = 1; Ret = CntStopCount( Id , ChNo , 2 );
C#	int Ret; short[] ChNo = new short[2]; ChNo[0] = 0; ChNo[1] = 1; Ret = cnt.StopCount( Id , out ChNo , 2 );
Python	Ret = ctypes.c_long() ChNoType = ctypes.c_short * 2 ChNo = ChNoType() ChNo[0] = 0 ChNo[1] = 1 Ret.value = ccnt.CntStopCount( Id , ChNo , 2 )
