Title: FunctionBlock for Average
Post by: Keithang on March 15, 2016, 02:00:01 PM: 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)

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

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.
