AioSetCntInputSignal

Function

Sets the type of counter input signal.

Format

Ret = AioSetCntInputSignal ( Id , CntChannel , CntInputSignal )

Parameters

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

CntChannel [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Sets the channel of counter.

CntInputSignal [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Sets the clock type from the following range.
The value that can be set is different according to device.

0	External clock (Fixed)

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.
15060	The value of CntChannel is outside the designated range of the function
15061	The value of CntClockType 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, counter 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.
25060	The value of CntChannel is outside the designated range of the device being used
25061	The value of CntClockType is outside the designated range of the device being used

Initial value

External clock for all devices

Remarks

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

Example

Uses the external clock for the clock type.

VB.NET	Dim Ret As Integer Ret = AioSetCntInputSignal ( Id , 0 , 0 )
C, C++	long Ret; Ret = AioSetCntInputSignal ( Id , 0 , 0 );
C#	int Ret; Ret = aio.SetCntInputSignal ( Id , 0 , 0 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSetCntInputSignal ( Id , 0 , 0 )
