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 ]

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.
12120	The value of AiTransferTimes is outside the designated range of the function
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 )
