(c) Moving average
This processing averages the digital output values taken in at each sampling cycle for a specified number of
times, storing the average value into CH
Digital operation value (RWr2 to RWr5, RWr12 to RWr15).
Because the averaging processing is performed on a moving set of sampling processing, the latest digital
operation values can be obtained.
The moving average processing for a set number of times of four is shown below:
(3) Setting procedure
The setting procedure for the main A/D converter module is as follows:
(a) Sampling processing
1.
Set "Method selection" to "Parameter write".
"CC IE Field Configuration" window
Select the main A/D converter module from "List of stations"
[CC IE Field Configuration]
[Online]
[Parameter Processing of Slave Station]
2.
In "Basic module parameter", set "CH
A/D conversion enable/disable setting" to "0: Enable".
3.
In "Basic module parameter", set "CH
Averaging process setting" to "0: Sampling processing".
For the extension A/D converter module, make the settings for each item of "Ext. module 1_Module parameter".
