Something like
(Val(1) + Val(2) + Val(3)) / 3
where 1, 2 and 3 are input channel numbers.
You need to add an extra input channel of calculated real type that uses the above formula.
How to do to average same variable along a certain time (n previous
readings)?
Create new formulas in the Formulas table depending on your needs. There are many different ways to calculate averages.
What does “averaging” column in Input Channels work if marked?
Summarizes all values received from controller and then divide by their count. This is performed separately when write minute and hourly data in the archive.
I implemented several averaging formulas in different projects. I can help you with averaging based on your requirements. But this is out of free support.
