AioSingleAoEx

Function

DA Converts the specified channel one time, the conversion data are specified in voltage/current. This function supports multi-process.

Format

Ret = AioSingleAoEx ( Id , AoChannel , AoData )

Parameters

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

AoChannel [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the channel to be converted.

AoData [ C, 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.

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.
13500	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.
23500	The value of AoChannel is outside the designated range of the device being used

Remarks

Before this function is executed, you must set the output range by 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.

When you use this function and "continuous functions", please refer "How to use simple functions and continuous functions at the same time" topics.

Example

It outputs voltage data 5V to channel 0.

C, C++	long Ret; Ret = AioSingleAoEx ( Id , 0 , 5.0 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSingleAoEx ( Id , 0 , 5.0 )
