AioOutputDoBit

Function

Outputs the data to the specified bit of digital output. This function supports multi-process.

Format

Ret = AioOutputDoBit ( Id , DoBit , DoData )

Parameters

Id [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the device ID retrieved from AioInit.

DoBit [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the bit of digital output.

DoData [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the output data.

0	OFF
1	ON

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.
14020	The value of DoBit is outside the designated range of the function Specify the digital output bit in range: 0 <= DoBit <= Max bit.
14021	The value of DoData is outside the designated range of the function
20001	This function can't be used by this device
24020	The value of DoBit is outside the designated range of the device being used

Remarks

This function cannot be used on devices without digital output functionality.

Specifications based on devices

The behavior depends on the [E-series settings] jumper on device.

If the [E-series settings] jumper on the device is [Do not use as E-series compatible], you can switch the I/O direction with AioSetDioDirection.

When accessing DIO00 to DIO07, specify 0 to 7 for the parameter DoBit.

When accessing DIO08 to DIO15, specify 8 to 15 for the parameter DoBit.

If the [E-series settings] jumper on the device is [Use as E-series compatible], DIO00 to DIO07 are fixed as Input, and DIO08 to DIO15 are fixed as output.

DIO00 to DIO07 cannot be accessed.

When accessing DIO08 to DIO15, specify 0 to 7 for the parameter DoBit.

You can switch the I/O direction with AioSetDioDirection.

When accessing DIO00 to DIO07, specify 0 to 7 for the parameter DoBit.

When accessing DIO08 to DIO15, specify 8 to 15 for the parameter DoBit.

Devices other than the above

When accessing DO00 to DO07, specify 0 to 7 for the parameter DoBit.

Access beyond the digital Output bits provided on the device is not possible.

Please refer to the device's hardware manual to confirm the number of Digital Output bits.

Example

Outputs 1 (ON) to bit 0.

VB.NET	Dim Ret As Integer Ret = AioOutputDoBit ( Id , 0 , 1 )
C, C++	long Ret; Ret = AioOutputDoBit ( Id , 0 , 1 );
C#	int Ret; Ret = aio.OutputDoBit ( Id , 0 , 1 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioOutputDoBit ( Id , 0 , 1 )
