Sets In Range when the conversion stop condition
is In Range comparison. The In Range is stored in Voltage or Current.
This settings is necessary when the conversion stop condition that is set
by AioSetAiStopTrigger function is the In Range comparison.
This function doesn't need to be executed when the conversion stop condition
is not "In Range comparison".
Only one level comparison setting can be set for one device. If specified multiple times, only the last data is valid.
Ret = AioSetAiStopInRangeEx ( Id , AiChannel , Level1 , Level2 , StateTimes )
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
]
Specifies the channel that performs the In Range comparison.
Level1
[ VB.NET : Single ] [ C, C++ : float ] [ C# : float ] [ Python : ctypes.c_float
]
Sets the upper limit of In Range comparison in Voltage or Current.
Level2
[ VB.NET : Single ] [ C, C++ : float ] [ C# : float ] [ Python : ctypes.c_float
]
Sets the lower limit of In Range comparison in Voltage or Current.
StateTimes
[ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long
]
Sets the number of samplings (1-256) within the state-held period after
the condition of In Range comparison is satisfied.
In fact, the conversion is stopped after sampling time of StateTimes elapses.
Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]

In all devices, AiChannel = 0, StateTimes = 1, Voltage or Current value equals to Level1, Level2 = 0 in binary.
This function cannot be used on devices without
the analog input function.
If the device is in operation, the function cannot be performed.

stop to channel 0.
The comparison data is -5.0 to 5.0V, state-held times is 0.
