DA Converts the more than one channel one time, the conversion data are specified in voltage or current. This function supports multi-process.
Ret = AioMultiAoEx ( Id , AoChannels , AoData )
Id
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the ID retrieved from AioInit function.
AoChannels
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the number of channels to be converted.
AoData
[ VB.NET : Single() ] [ C, C++ : float * ] [ C# : float[] ] [ Python :
ctypes.POINTER(ctypes.c_float) ]
Specifies the address of the array that stores 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 ]

23520 |
DA conversion error occurred |
23521 |
The number of conversion channels was exceeded. It is converted on the maximum channels |
If a device has the synchronous output function, it outputs the set channels at the same time. If the device have no the synchronous output function, it transparently (one after another output) outputs to the channels in the order of channel 0, 1, 2 and so on.
Before this function is executed, you must
set the output range by using AioSetAoRange
or AioSetAoRangeAll function
This function cannot be used on devices without the analog output function.
If the device is in operation, the function cannot be performed.
It outputs voltage data 5V to channel 0 to channel 7.
