Create a totalizer that gives the daily average?

Hello everyone!

 

I want to log the daily average of the previous 24 hours for one of my existing tags.  Each of these tags are analog signals.  An example would be a feed flow in gallons per minute (GPM).  I am trying to achieve this using the Totalizer in PI.  I am a novice at PI.

 

I am using PI Data Archive 2015 R2.  I downloaded the PI Data Archive 2015 R2 Applications User Guide.  I began reading the PI Totalizer Subsystem (Totalizer) section of the user guide.  There are lots of parameters that can be changed and as a novice I could use some guidance.

 

I started looking at the parameters.  This is what I think I need:

  • RateSampleMode = Natural (default)
  • TotalCloseMode = Clock (default)
  • ReportMode Function = Average
  • CalcMode = TimeWeighted
  • Period = ?? I'm not sure what to put here
  • Offset = ?? I'm not sure what to put here
  • What other parameters do I need to update? Any suggestions?

 

Do I need to create an equation for this?

 

Thanks!
