CntSetSamplingClockTrigger

Function

Sets sampling clock trigger conditions.

Format

Ret = CntSetSamplingClockTrigger ( Id , ClockTrg )

Parameters

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

ClockTrg [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the sampling clock conditions.

Definition	Value	Description
CNTS_CLOCK_CLOCK	1	Internal Clock
CNTS_CLOCK_EXT_TRG	2	External Clock
CNTS_CLOCK_EXTSIG_1	3	Synchronous Connector EXTSIG1
CNTS_CLOCK_EXTSIG_2	4	Synchronous Connector EXTSIG2
CNTS_CLOCK_EXTSIG_3	5	Synchronous Connector EXTSIG3

* Synchronous connector signal cannot be specified for the devices without Synchronous Connector.

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_MEMORY	20000	It failed in memory allocation for the object preparation.
CNT_ERR_SYS_NOT_SUPPORTED	20001	This function can't be used by this device.
CNT_ERR_SYS_USING_OTHER_PROCESS	20003	Cannot use because another process is using the device.
CNT_ERR_SYS_CLOCK_TRG	21007	The clock condition is out of range.

The others: (See also: Details of Error Code)

Initial Value

Internal Clock

Remarks

Must set clock condition in order to make the application operation regular. This function should be executed in the setting stage before sampling starts. Set the internal clock value by the function CntSetSamplingInternalClock if Internal Clock is used.

Example

Uses Internal Clock to sampling clock condition.

VB.NET	Dim Ret As Integer Ret = CntSetSamplingClockTrigger ( Id , CNTS_CLOCK_CLOCK )
C, C++	long Ret; Ret = CntSetSamplingClockTrigger ( Id , CNTS_CLOCK_CLOCK );
C#	int Ret; Ret = cnt.SetSamplingClockTrigger ( Id , (short)CcntConst.CNTS_CLOCK_CLOCK );
Python	Ret = ctypes.c_long() Ret.value = ccnt.CntSetSamplingClockTrigger ( Id , ccnt.CNTS_CLOCK_CLOCK )
