Issue with OEE, Performance, and Quality Not Calculating in ThingWorx RTPPM

[SK_11160607]

I recently installed and configured ThingWorx RTPPM, and while setting up the Operations Dashboards, I encountered an issue where only Availability is being calculated. The OEE, Performance, and Quality metrics are not being calculated and are displaying 0, even though other aspects of RTPPM seem to be functioning correctly.

Has anyone faced a similar issue or have any suggestions on troubleshooting this? Any guidance on what to check next would be greatly appreciated.

Thanks!

Hi SK

So your production events have quantities, but your Performance and Quality KPIs are 0. To have an understanding of how the KPIs are calculated, I suggest you go in the KPI Dashboard screen, select your equipment, choose the This Shift time period, and click on the OEE number so it opens this popup :

You can also open the popups for the other KPIs. If you have 0s in your KPIs, then you should have some specific values that are 0s and cause the final result to be 0.

I can see an issue in your screenshot is under your quantities, the Ideal Rate is empty (NAN). This is most likely the problem for Performance, as it's the difference between Ideal Production and Total Production (as seen in the OEE popup). In order to have ideal production, you must set the nominal value of a limit that fits the current run (equipment = Filling Machine 1, Product Type = ..., Product = Machine). To enter limits, go in the Configuration -> Characteristics screen, make sure in the Characteristics tab you have one with the Ideal Production type and the correct UOM (such as kg), and then in the Limits tab you can download the template, fill it, and click on Import to add it in the database.

For the Quality, just based on your screenshot I can't tell what is wrong. The KPI popups as I mentioned above should tell you which number(s) is not working. One issue that I have seen before was when people set the Production and Waste attributes as different UOMs, such as kilograms vs liters. To check that, you can go in the Configuration -> Equipment screen, select your equipment, go in the Attributes tab and try to edit them to see the UOM. Another one was the status type system, as I will explain in the first Article below.

Here are a few existing Articles that touch this issue. If my suggestions above don't solve the issue, you should have a look and see if these Articles can fix it. In particular the first 2 look very promising for your issue.

• 000363687 : Performance KPI stays at 0% in Thingworx Real-Time Production Performance Monitoring
• 000350738 : Quality KPI stays at 0% for some equipments in Thingworx Real-Time Production Performance Monitoring
• 000417894 : Performance Percent showing 0 or inaccurate values in ThingWorx Real-Time Production Performance Monitoring

Thank you for the solution! It worked, and now OEE, Performance and Quality is being calculated correctly.
