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 ]

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.
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.
