Function
Retrieves the generating count of the analog output.
Format
Ret = AioGetAoSamplingCount ( ID , AoSamplingCount )
Parameters
Id
[ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.
AoSamplingCount
[ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the generating count.
Return value
Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

Execute AioResetDevice function because the device has recovered from standby mode |
10001 |
Invalid
Id was specified |
10002 |
AIO
driver can't be called |
13400 |
Pointer
to AoSamplingCount is NULL |
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, AoSamplingCount = 0
Remarks
Resets this value to 0 by calling AioResetAoMemory function.
Stores the generating counts of all channels
used in the AioStartAo.
This function can be executed even if the device is in operation.
This function cannot be used on devices without the analog output function.
Example
Retrieves the generating count (location) from the device memory (software memory).
