AioGetAiInputMethod


Function

Retrieves the analog input method. This function supports multi-process.

Format

Ret = AioGetAiInputMethod ( Id , AiInputMethod )

Parameters

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

AiInputMethod [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the analog input method.

0

Single-end input

1

Differential input

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
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.

11010

Pointer to AiInputMethod 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 input operation must be stopped.

Initial value

It differs by the device type and the JP settings.

Remarks

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