AioSetAiScanClock

Function

Sets the conversion speed.

Format

Ret = AioSetAiScanClock ( Id , AiScanClock )

Parameters

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

AiScanClock [ C, C++ : float ] [ Python : ctypes.c_float ]
Specifies the conversion speed in usec.
The available range differs by the device.

Return value

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

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.

12240

The value of AiScanClock 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.

The value of AiScanClock is outside the designated range of the device being used

Initial value

Minimum value by the device type.

Remarks

Available conversion speed is changed by sampling clock period.
This function cannot be used on devices without the analog input function.
If the device is in operation, the function cannot be performed.
