AioSetAiClockType

Function

Sets the clock type.

Format

Ret = AioSetAiClockType ( Id , AiClockType )

Parameters

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

AiClockType [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Sets the clock type from the following range.
The available value differs by the device.

0	Internal clock
1	External clock
10	Event controller output

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.
11120	The value of AiClockType is outside the designated range of the function Set 0(clock for conversion), 1(external clock) or 10(event controller output) to AiClockType.
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.
21120	The value of AiClockType is outside the designated range of the device being used

Initial value

Internal clock is used for all devices.

Remarks

If the internal clock is used as the clock, please use AioSetAiSamplingClock function to set the internal clock.
If the event controller output is used as the clock, please use AioSetEcuSignal function to set the connection of the event controller.
If you only perform this function, the connection of the event controller isn't changed.

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

Example

Uses the internal clock as the clock type.

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