AioGetAiResolution

Function

Retrieves the resolution of the analog input. This function supports multi-process.

Format

Ret = AioGetAiResolution ( Id , AiResolution )

Parameters

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

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

10	10 bit resolution
12	12 bit resolution
16	16 bit resolution
0	No analog input functionality

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.
11740	Pointer to AiResolution is NULL Specify the address of variable to parameter.
20002	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.

VB.NET	Dim Ret As Integer Dim AiResolution As Short Ret = AioGetAiResolution ( Id , AiResolution )
C, C++	long Ret; short AiResolution; Ret = AioGetAiResolution ( Id , &AiResolution );
C#	int Ret; short AiResolution; Ret = aio.GetAiResolution ( Id , out AiResolution );
Python	Ret = ctypes.c_long() AiResolution = ctypes.c_short() Ret.value = caio.AioGetAiResolution ( Id , ctypes.byref(AiResolution) )
