AioGetAiStopTriggerCount

Function

Retrieves the sampling count when the stop trigger is input.
This function can only be used when the transfer mode of the conversion data that is set by AioSetAiTransferMode is Device buffer mode.
It cannot be used when the transfer mode of the conversion data is User buffer mode.

Format

Ret = AioGetAiStopTriggerCount ( ID , AiStopTriggerCount )

Parameters

Id [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the ID retrieved from AioInit function.

AiStopTriggerCount [ VB.NET : Integer ] [ C, C++ : long * ] [ C# : out int ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the input location of stop trigger.

Return value

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

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
11560	Pointer to AiStopTriggerCount is NULL Specify the address of variable to parameter.
20001	This function can't be used by this device
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.

Initial value

In all devices, AiStopTriggerCount = 0

Remarks

The retrieved value by calling this function is overwritten when input stop condition of the next stop trigger is satisfied.

Resets this value to 0 by calling AioResetAiMemory function.

This function cannot be used on devices without the analog input function.
This function can be executed if the device is working.

Example

Retrieves the sampling count when the stop trigger is input.

VB.NET	Dim Ret As Integer Dim AiStopTriggerCount As Integer Ret = AioGetAiStopTriggerCount ( Id , AiStopTriggerCount )
C, C++	long Ret; long AiStopTriggerCount; Ret = AioGetAiStopTriggerCount ( Id , &AiStopTriggerCount );
C#	int Ret; int AiStopTriggerCount; Ret = aio.GetAiStopTriggerCount ( Id , out AiStopTriggerCount );
Python	Ret = ctypes.c_long() AiStopTriggerCount = ctypes.c_long() Ret.value = caio.AioGetAiStopTriggerCount ( Id , ctypes.byref(AiStopTriggerCount) )
