AioSetCntComparisonReg

Function

Sets the comparison count value loaded.

Format

Ret = AioSetCntComparisonReg ( Id , CntChannel , ComparisonNumber, ComparisonData, Flag )

Parameters

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

CntChannel [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Sets the channel of counter.

ComparisonNumber [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]
Specifies the total number of comparison count data to be set.

ComparisonData [ VB.NET : Integer() ] [ C, C++ : long * ] [ C# : int[] ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the pointer to the array that stores the comparison count.
The range that can be set is different according to devices.

Flag [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies whether to repeatedly set the data array of comparison count value.

0	Not repeat
1	Repeat

If Repeat is set, the first comparison count value data of the array is set again when the last comparison count value of the array matches the next comparison count set.
If Not repeat is set, data isn't preset when the last comparison count value of the array matches the followed comparison count set.

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.
15040	The value of CntChannel is outside the designated range of the function
15041	The value of ComparisonNumber is outside the designated range of the function
15042	The value of Flag is outside the designated range of the function
15043	Pointer to ComparisonData 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, counter 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.
25040	The value of CntChannel is outside the designated range of the device being used
25041	The value of ComparisonNumber is outside the designated range of the device being used

Initial value

None

Remarks

The value sets the comparison count value when starting the counter function.

The value sets by using this function is loaded as the next comparison count value after comparison count match.
The values set in the array are set in turn when comparison count match occurs every time.

If the comparison count value is fixed, please set ComparisonNumber = 1 and Flag = 1.

In order to use this functionality, you should set comparison count value load as the operation mode by using the function AioSetCntComparisonMode.
This function cannot be used on devices without counter functionality.
If the device is in operation, the function cannot be performed.
