AioGetAoTransferMode


Function

Retrieves the transfer mode of the analog output conversion data. 

Format

Ret = AioGetAoTransferMode ( Id , AoTransferMode )

Parameters

Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.

AoTransferMode [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the transfer mode of the conversion data.

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.

Pointer to AoTransferMode is NULL
Specify the address of variable to parameter.

20001

This function can't be used by this device

20002

Can not use while by another device works
To use this function, analog output operation must be stopped.

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, AoTransferMode = 0

Remarks

This function cannot be used on devices without the analog output function.
If the device is in operation, the function cannot be performed.
