AioGetAiScanClock

Function

Retrieves the conversion speed.

Format

Ret = AioGetAiScanClock ( Id , AiScanClock )

Parameters

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

AiScanClock [ VB.NET : Single ] [ C, C++ : float * ] [ C# : out float ] [ Python : ctypes.POINTER(ctypes.c_float) ]
Specifies the address of the variable that stores the conversion speed.

Return value

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

12250

Pointer to AiScanClock is NULL
Specify the address of variable to parameter.

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

The fastest conversion speed is set for each device.

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

Retrieves the conversion speed that is set.

VB.NET

Dim Ret As Integer
Dim AiScanClock As Single
Ret = AioGetAiScanClock ( Id , AiScanClock )
 

C, C++

long Ret;
float AiScanClock;
Ret = AioGetAiScanClock ( Id , &AiScanClock );
 

C#

int Ret;
float AiScanClock;
Ret = aio.GetAiScanClock ( Id , out AiScanClock );
 

Python

Ret = ctypes.c_long()
AiScanClock = ctypes.c_float()
Ret.value = caio.AioGetAiScanClock ( Id , ctypes.byref(AiScanClock) )
