Ret = AioGetAiResolution ( Id , AiResolution )

Parameters

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

AiResolution [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the resolution.

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.

11740

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

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

Remarks

If the device is in operation, the function cannot be performed.

Example

Retrieves the resolution of the analog input.

C, C++

long Ret;
short AiResolution;
Ret = AioGetAiResolution ( Id , &AiResolution );
 

Python

Ret = ctypes.c_long()
AiResolution = ctypes.c_short()
Ret.value = caio.AioGetAiResolution ( Id , ctypes.byref(AiResolution) )
