AioGetAiStopInRangeEx

Function

Retrieves the settings of In Range comparison stop condition. The In Range is stored in Voltage or Current.

Format

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

Parameters

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

AiChannel [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Fixed to 0. (Reserved)

Level1 [ VB.NET : Single ] [ C, C++ : float * ] [ C# : out float ] [ Python : ctypes.POINTER(ctypes.c_float) ]
Specifies the address of the variable that stores the upper limit data of In Range comparison. The data are stored in Voltage or Current.

Level2 [ VB.NET : Single ] [ C, C++ : float * ] [ C# : out float ] [ Python : ctypes.POINTER(ctypes.c_float) ]
Specifies the address of the variable that stores the lower limit data of In Range comparison. The data are stored in Voltage or Current.

StateTimes [ VB.NET : Integer ] [ C, C++ : long * ] [ C# : out int ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the state times.

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.
12410	The value of AiChannel is outside the designated range of the function Specify the channel setting in range: 0 <= AiChannel <= Max channel.
12411	Pointer to Level1 is NULL Specify the address of variable to parameter.
12412	Pointer to Level2 is NULL Specify the address of variable to parameter.
12413	Pointer to StateTimes 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.
22410	The value of AiChannel 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

Retrieves the In Range comparison level and state times of channel 0.
