AioSetAiEventTransferTimes


Function

Sets the data transfer times when the "Event that the specified number of data are transferred" is used.
This settings is necessary when the transfer mode of the conversion data that is set by AioSetAiTransferMode function is User buffer mode.
This function needn't be executed if the transfer mode of the conversion data is Device buffer. 

Format

Ret = AioSetAiEventTransferTimes ( Id , AiTransferTimes )

Parameters

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

AiTransferTimes [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]
Sets the data transfer times that cause the event to raise.

Return value

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

20001

This function can't be used by this device

20002

Can not use while by another device works
To use this function, analog input operation must be stopped.

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.

Initial value

In all devices, 500

Remarks

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

Example

Sets 5000 to the transfer times when "Event that the specified number of data are transferred" is specified.

VB.NET

Dim Ret As Integer
Ret = AioSetAiEventTransferTimes ( Id , 5000 )
 

C, C++

long Ret;
Ret = AioSetAiEventTransferTimes ( Id , 5000 );
 

C#

int Ret;
Ret = aio.SetAiEventTransferTimes ( Id , 5000 );
 

Python

Ret = ctypes.c_long()
Ret.value = caio.AioSetAiEventTransferTimes ( Id , 5000 )
