Function
Retrieves the transfer 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 User buffer mode.
It cannot be used when the transfer mode of the conversion data is Device
buffer mode.
Format
Ret = AioGetAiStopTriggerTransferCount ( ID , Count )
Parameters
Id
[ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.
Count
[ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the transfer count when
the stop trigger is input.
Return value
Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

20001 |
This function can't be used by this device |
20003 |
Can
not use because another process is using the device |
Initial value
In all devices, Count = 0
Remarks
The retrieved value by calling this function is overwritten when input stop condition of the next stop trigger is satisfied.
Count is automatically reset to 0 when the conversion is started by AioStartAi.
This function cannot be used on devices without
the analog input function.
This function can be executed if the device is in operation.
