AioStopAo

Function

Stops the DA conversion.

Format

Ret = AioStopAo ( Id )

Parameters

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

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.
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.

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

Stops the DA conversion.

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