AioSetAiEventSamplingTimes

Function

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

Format

Ret = AioSetAiEventSamplingTimes ( Id , AiSamplingTimes )

Parameters

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

AiSamplingTimes [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]
When the event factor is "Event that the specified number of data are stored", set the number of samplings that raises event.

Return value

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

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.

11400

The value of AiSamplingTimes is outside the designated range of the function
AiSamplingTimes should be set to a value greater than or equal to 0.

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

It differs by the device type.

Remarks

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