AioStopAo


Function

Stops the DA conversion.

Format

Ret = AioStopAo ( Id )

Parameters

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

Return value

Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]

Return values

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.

20001

This function can't be used by this device

20003

Can not use because another process is using the device
When another process is using the device, all functions except for those that support multi-process can not be performed.

Remarks

Stops the action regardless of the converting status. The relay circuit is still ON. To set the delay circuit to OFF, please execute the AioDisableAo function.

If more than one channel are converted, the generating stops after the conversion of all channels completes when the command is executed.

When FIFO memory is used, the conversion data which have not been output are being left in the memory even if the conversion is stopped by this function. In this status when AioStartAo is executed once more, the conversion start, the data is continued to output.

This function cannot be used on devices without the analog output function.
This function can be executed even if the device is in operation.

Example

C, C++

long Ret;
Ret = AioStopAo ( Id );
 

C#

int Ret;
