I have recently updated my old version of PI Server last July, and noticed that the snapshot from equation at the PI Archive are not updated.
Weird things is, no error are shown when i click the Evaluate button. Any idea on the issue?
As per the screenshot, you are evaluating performance equation. Please answer below questions to help you to idenify the cause for this issue.
1. Are these PE calculation is event triggered/ clock based? If it is event triggered, Can you please check updating status of source tag.
2. Are you facing this issue only for this particular tag/any other tags?Please check the status of all PE tags for this particular instance.
Hi Ramesh. Just found out that the PI Performance Equation Scheduler are no longer available in the PI Server 2018. how do i enable the features?
As described in the article (Missing PI components after installing or upgrading to PI Server 2018), you need to rerun the install kit and click the "Individual Features" tab to manually select PI Server feature(s). One of those which is not selected by default is PI Performance Equation Scheduler.
Please keep in mind, that Asset Analytics is intended as a complete replacement for PI Performance Equations and our recommendation is that any new calculations should be done via Asset Analytics and not Performance Equations, since Asset Analytics provides better performance, scalability and makes it easier to write and debug calculations.
As mentioned by Piotr, you need to rerun PI Server Installation Kit and select PI Performance Equation Scheduler features in individual features. Attached the screenshot below for your reference.
yeah i did run it last week, but the PI Performance Equation weren't there in the list i think. Let me double check again later
