AioSetAiStartInRangeEx

Function

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

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

Format

Ret = AioSetAiStarInRangeEx ( 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 In Range comparison.

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

Level2 [ C, C++ : float ] [ Python : ctypes.c_float ]
Sets the lower limitof In 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 In Range comparison is satisfied.
In fact, the conversion is started after sampling time of StateTime 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.
12270	The value of AiChannel is outside the designated range of the function Specify the channel setting in range: 0 <= AiChannel <= Max channel.
12271	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.
22270	The value of AiChannel is outside the designated range of the device being used
22271	The value of Level1 or Level2 is outside the designated range of the device being used
22273	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 In Range comparison start to channel 0.
The comparison data is 5.0V to -5.0V, state-held times is 1.

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