AioSetAoStartTrigger

Function

Sets the conversion start condition.

Format

Ret = AioSetAoStartTrigger ( Id , AoStartTrigger )

Parameters

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

AoStartTrigger [ C, C++ : short ] [ Python : ctypes.c_short ]
Sets the conversion start condition from the following range.
The available value differs by the device.

0	Software
1	External trigger rising edge
2	External trigger falling edge
10	Event controller output

Return value

Ret [ C, C++ : long ] [ 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.
13240	The value of AoStartTrigger 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 output 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.
23240	The value of AoStartTrigger is outside the designated range of the device being used

Initial value

Software start for all devices

Remarks

If you only perform this function, the connection of the event controller isn't change. This function cannot be used on devices without the analog output function.
If the device is in operation, the function cannot be performed.
