Function
Retrieves the settings of Out Range comparison stop condition.
Format
Ret = AioGetAiStopOutRange ( 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 ]
Reserved. it should set 0(Zero).
Level1
[ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the upper limit data
of Out Range comparison. The data are stored in binary value.
Resolution of device is 12 bit |
0 to 4095 |
Resolution of device is 16 bit |
0 to 65535 |
Level2
[ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the lower limit data
of Out Range comparison. The data are stored in binary value.
Resolution of device is 12 bit |
0 to 4095 |
Resolution of device is 16 bit |
0 to 65535 |
StateTimes
[ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the state-held sampling
times.
Return value
