AioSingleAo

Function

DA Converts the specified channel one time, the conversion data are specified in binary value. This function supports multi-process.

Format

Ret = AioSingleAo ( Id , AoChannel , AoData )

Parameters

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 : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]
Specifies the output data. Please specify the data in binary value.
The available value differs by the device.

Resolution of device is 12 bit	0 to 4095
Resolution of device is 16 bit	0 to 65535

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.
13000	The value of AoChannel is outside the designated range of the function Specify the channel setting in range: 0 <= AoChannel <= Max channel.
20001	This function can't be used by this device
20002	Can not use while by another device works To use this function, analog output operation must be stopped.
23000	The value of AoChannel is outside the designated range of the device being used
23002	Specify data to establish in AoData in the range of 0 to 4095
23003	Specify data to establish in AoData in the range of 0 to 65535

Remarks

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

Example

It outputs binary data 2048 to channel 0.

VB.NET	Dim Ret As Integer Ret = AioSingleAo ( Id , 0 , 2048 )
C, C++	long Ret; Ret = AioSingleAo ( Id , 0 , 2048 );
C#	int Ret; Ret = aio.SingleAo ( Id , 0 , 2048 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSingleAo ( Id , 0 , 2048 )
