AioGetDiFilter

Function

Retrieves the filter time set based on digital input signal.

Format

Ret = AioGetDiFilter ( Id , Bit , Value )

Parameters

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

Bit [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the input bit for setting filter.
Only -1 can be specified now.

Input bit	Value
Input bit 0 (Reserved)	0
Input bit 1 (Reserved)	1
Input bit 2 (Reserved)	2
Input bit 3 (Reserved)	3
All signals above	-1

Value [ VB.NET : Single ] [ C, C++ : float * ] [ C# : out float ] [ Python : ctypes.POINTER(ctypes.c_float) ]
Specifies the address of the variable that stores the filter time. The unit is usec.
0 means no filter.

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.
14050	The value of Bit is outside the designated range of the function
14051	Pointer to Value is NULL
20001	This function can't be used by this device
20002	Can not use while by another device works
20003	Can not use because another process is using the device
24050	The value of Bit is outside the designated range of the device being used

Initial value

Retrieves the filter setting set to all bits.

Remarks

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

Example

Retrieves the filter values set for all input bits.

VB.NET	Dim Ret As Integer Dim Value As Single Ret = AioGetDiFilter ( Id , -1 , Value )
C, C++	long Ret; float Value; Ret = AioGetDiFilter ( Id , -1 , &Value );
C#	int Ret; float Value; Ret = aio.GetDiFilter ( Id , -1 , out Value );
Python	Ret = ctypes.c_long() Value = ctypes.c_float() Ret.value = caio.AioGetDiFilter ( Id , -1 , ctypes.byref(Value) )
