CntStopNotifyCountUp

Function

Stops the notification by the count match. Supports multi-processing.

Format

Ret = CntStopNotifyCountUp ( Id , ChNo , RegNo )

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#: short ] [ Python: ctypes.c_short ]
Specify the channel number for setting.

RegNo [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the register number of the comparison register. For USB device, specify 0.

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_SYS_NOT_SUPPORTED	20001	This function can't be used by this device.
CNT_ERR_SYS_CH_NO	20201	Channel number is out of range.

Initial Value

None

Remarks

This function stops the notification of count value comparison message made effective by the CntNotifyCountUp function.
Please call the function CntNotifyCountUp when the notification becomes valid again.

In this function, because the comparison register is not set, when the comparison register is corresponding to count value, if the pulse length is set by the function CntSetPulseWidth, the pulse is output outside.
Set the pulse length to 0 by the function CntSetPulseWidth when the pulse is stopped.

Example

Stops the notification by the count match of channel 0.

VB.NET	Dim Ret As Integer Ret = CntStopNotifyCountUp( Id , 0 , 0 )
C, C++	long Ret; Ret = CntStopNotifyCountUp( Id , 0 , 0 );
C#	int Ret; Ret = cnt.StopNotifyCountUp( Id , 0 , 0 );
Python	Ret = ctypes.c_long() Ret.value = ccnt.CntStopNotifyCountUp( Id , 0 , 0 )
