DA Converts the specified channel one time, the conversion data are specified in voltage/current. This function supports multi-process.
Ret = AioSingleAoEx ( Id , AoChannel , AoData )
Id
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the ID retrieved from AioInit function.
AoChannel
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the channel to be converted.
AoData
[ VB.NET : Single ] [ C, C++ : float ] [ C# : float ] [ Python : ctypes.c_float
]
Specifies the output data. Please specify the data in voltage or current.
The available value differs by the device.
Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]
