FunctionBlock for Average

[Keithang]

Hi,

We are busy programing a Pressure sensor however we have erratic values being relayed into the controller which in turn causes our test to fail.

A solution would be to gather information for a certain amount of time, and use the average to set failure or pass value.

Is there a function block to log and work out an average?
Eg.
1 - 5
2 - 3
3 - 10
4 - 5
5 - 1

Average for above is 4.8 (Values (24)added and divided by log number (5)

Hi,
have you tried the average filters in the Filters functions library?

Hi,

Yes we have.

We have created our own function library to calculate the average and give a more stable and accurate reading. Readings match a Physical gauge.

Why didn't the Plus+1 average filter block work for you?

I came across a sample of a high pass filter. not so long ago. I thought to find it here. Did somebody deleted it or somebody knows where to find it. I was looking forward to try it.

Hello, I am new to Plus 1 programming, and need to do a similar task, is there any advice or maybe a screenshot on how to handle it?

Thank you very much!

Try the average filter function block, read up on the user manual this will explain in detail how it works.
