AioSetAiStartOutRangeEx

Function

Sets Out Range when the conversion start condition is Out Range comparison. The Out Range is stored in Voltage or Current.
This settings is necessary when the conversion start condition that is set by AioSetAiStartTrigger function is Out Range comparison.
This function doesn't need to be executed when the conversion start condition is not Out Range comparison.

It can be set only 1ch for each device. The latest setting is available when you set it several times.

Format

Ret = AioSetAiStartOutRangeEx ( Id , AiChannel , Level1 , Level2 , StateTimes )

Parameters

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

AiChannel [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the channel that performs the Out Range comparison.

Level1 [ C, C++ : float ] [ Python : ctypes.c_float ]
Sets the upper limit of Out Range comparison in Voltage or Current.

Level2 [ C, C++ : float ] [ Python : ctypes.c_float ]
Sets the lower limit of Out Range comparison in Voltage or Current.

StateTimes [ C, C++ : long ] [ Python : ctypes.c_long ]
Sets the number of samplings within the state-held period after the condition of Out Range comparison is satisfied.
In fact, the conversion is started after sampling time of StateTimes elapses.

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.
12290	The value of AiChannel is outside the designated range of the function Specify the channel setting in range: 0 <= AiChannel <= Max channel.
12291	The value of StateTimes 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 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.
22290	The value of AiChannel is outside the designated range of the device being used
22291	The value of Level1 or Level2 is outside the designated range of the device being used
22293	The value of StateTimes is outside the designated range of the device being used

Initial value

In all devices, AiChannel = 0, StateTimes = 1, Voltage or Current value equals to Level1, Level2 = 0 in binary.

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

Sets Out Range comparison start to channel 0.
Comparison data is 5.0V to -5.0V, the state-held times is 1.

C, C++	long Ret; Ret = AioSetAiStartOutRangeEx ( Id , 0 , 5.0 , -5.0 , 1 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSetAiStartOutRangeEx ( Id , 0 , 5.0 , -5.0 , 1 )
