AioGetAiStopTrigger

Function

Retrieves the conversion stop condition.

Format

Ret = AioGetAiStopTrigger ( Id , AiStopTrigger )

Parameters

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

AiStopTrigger [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the conversion stop condition.

0	Stop conversion by the specified times
1	External trigger rising edge
2	External trigger falling edge
3	Level comparison
4	Command (AioStopAi)
5	In Range comparison
6	Out Range comparison
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.
11270	Pointer to AiStopTrigger 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

In all devices, Stop conversion by the specified times

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 stop condition.

C, C++	long Ret; short AiStopTrigger; Ret = AioGetAiStopTrigger ( Id , &AiStopTrigger );
Python	Ret = ctypes.c_long() AiStopTrigger = ctypes.c_short() Ret.value = caio.AioGetAiStopTrigger ( Id , ctypes.byref(AiStopTrigger) )
