I want get an average minute value of a tag but within for example:

average value of 'sinusoid' within 08:00:00 and 08:01:00, with seconds in 00 and it value update every minute

i.e. the next minute it will show average value of 'sinusoid' within 08:01:00 and 08:02:00.

I know that a can get average value with "PI Calc" and using a "calculation interval" of 1M but it doesn't assure me that averages is within time seconds in 0.

Hi Octavio,

The easiest way would be to use Asset Analytics with AF. If you set up an equation like the following, you can get a minute average of an input tag:

Note that the scheduling is Periodic, set to run every minute with a 0s offset. So, this will run at 12:00:00, 12:00:01, etc., and output an average of the previous minute of data.

Here's an example of 2 hours of 1-minute-averaged CDT158 data:

You could then use the output tag in any ProcessBook display.

If you don't have Asset Analytics at your disposal, you could also accomplish this with Performance Equations or with Totalizers.
