Calculating the Conversion Cycle
The conversion cycle speed can be improved by setting the number of AD
conversion points, but will vary with the use of the math operations. Use the
following table and formula to calculate the conversion cycle time.
Formula
AD conversion cycle time = AD base conversion time + (Additional time for
each function)
AD base conversion time: Cycle time when the math operation is not used at
all. The value for each conversion point from 1 to 2 is different.
Extra time for each function: The additional time that is required when math
operations are used.
The following table shows the AD base conversion times (unit: ms).
Note
The DeviceNet communications cycle is 4 ms.
