How do I find the sum of values (not integrals) of a tag over a period of time?

I am trying to sum up values of a tag over a period of 24 hours. However, I have tried using the TagTot function but the answer did not come out the way I expected. The aim of my analyses is to sum up the percentage completion of the batches that happens within a window of 24hours. So for example, within a 24 hour window, I have 2.5 batches… (Show more Show less)

Thank you for your answer Rick, but I do believe there should be some best practices, just to mention few questions: - how should be connected PI Server DEV with PI Server PRD? - it's recommendable to integrate PI Server DEV with PI Interfaces? - there should be PI Interfaces DEV? - It's useful to connect PI AF DEV / PI Vision DEV with PI…

Querying Analysis Runtime Information using AFSDK

Introduction Asset Analytics is a widely used feature of PI Asset Framework (PI AF) that allows users to configure calculations using PI data and quickly apply it to many assets using AF Templates. Once users have implemented the business logic and scheduled the calculations, PI Analysis Service picks up these newly created analyses and executes… (Show more Show less)

I don't think the Analysis Service keeps track of skipping based on time, it only keeps track of skipping since the service start. You could easily handle this in code though by periodically querying the skip count and calculating the difference. Even in large systems, if you are querying only running analyses, the performance should be very good…

After deleting thousands of PI Points from PI Builder, how can I delete de values associated to those PI Points stored in PI Archive?

Due to obsolescence and error in applicating a formula to thousands of PI Points, I have been to delete those PI Points using the SMT PI Builder function. I have checked that Archives files number of events and size have not been reduced, so I suspect milion ov values associated to those deleted PI Points remain in the PI Data Archive. How… (Show more Show less)

With the newer PI Server versions, you can reprocess an archive directly from PI SMT. Just right click on the archive and select "Reprocess Archive"

Is this a new installation of Data Archive 2018 SP3? If so, please note that the Random Interface is no longer bundled with that version of the installation kit. Instead, the Random interface can be separately downloaded and installed from the Customer Portal. Otherwise, if you do have the Random Interface installed and running, please take…

What specific interface do you need to recover for? For most of them, it would simply involve recovering the latest BAT file and possibly other configuration files (INI, queries) depending on the specific interface. Then, once those files are recovered, simply re-install the interface on the new node and register those instances with ICU and…

Parallel processing of AF Analysis recalculation?

Hi I'm wondering why my analysis backfills/recalcs aren't being processed in parallel? Shouldn't they be doing that under normal circumstances? These are Event Frame generation analyses, and as an extra layer to my setup I have table lookups inside the EF template, relying on a parameterized table lookup. I'm wondering if that could be… (Show more Show less)

I forgot to attach this screenshot, but this is basically what's happening if I try to trend the table lookup attribute where I use your #StartTime# trick from the other thread. There's always an error first, then there's the correct value (both are listed at the same timestamp). If you change retrieval mode to single time you'll see what…

Filter Expression in PI AF Expression Analysis

Hi, I am trying to do a simple Expression Analysis but it's been a long time since I haven't done so in PI AF and I'm running into a small blockage. I think the solution should be quite simple though. I want to create a calculation for the daily production of one of our units. The calculation is basically the flow rate of the outlet multiplied… (Show more Show less)

Sebastian, I am using 2018 SP2. TagAvg works perfectly as you would expect. The issue I am having is with filtered tim-weighted averages, e.g. average (TagA) when TagB>1000 and TagC>1000. I understand that AF 2018 supports arrays, but I am not sure how that could be used in this case. RecordedValues will give me an array of values of the…
