Reopening this suggestion to collect additional feedback.

Customers doing pattern recognition and prognostics often need multivariable, nonlinear functions to model the physical behavior they see. Extensible analytics keep projects rooted in PI AF and provide feedback to us as to what functions need to be included in our product.

this may be better solved on the backend as tag property similar to STEP. A property that disables extending the most recent value to present. i ran into this in analytics using FindEq(). customer had LIMS sample data. Unlike sensor data, sample data by nature applies to the orig timestamp only. Customer needed to query backwards in time to find a particular sample timestamp. If in a polling schedule FindEq() returned current time rather than the most recent sample time.

i could dream of the option to add translation layers per language and then allow users to toggle language in the client tools. could we one-shot a language translation and then allow user edits to polish the attrib names/descr. seems possible, is it manageable?

we are using FFT currently in analyzing PID controller strain. FFT has broad application. We have built a custom symbol in PI vision for FFT analysis. Works well as an ad hoc data science tool and links nicely to event frames in pi vision.

This is needed in a range of cases. One broad example is machine vibration data from accelerometers for condition based maintenance.

I agree that FFT would be valuable in AF functions. If it's any consolation you can currently build your own FFT symbol in PI vision to get the ball rolling as an ad hoc user activity. The event frames UI in PI Vision can help you manage these ad hoc data sets to be more structured. Hope this helps.

This feature is part of version 2 of the IT Asset Example kit coming out later this summer from the Delivery Services team at OSIsoft. Many more notifications just like this are included in this AF example kit. If interested feel free to reach out to me.

it would be interesting to see the cost analysis on this. how much $$ would it save the user

very interested. We are working with CBM use cases in vibration that desperately need this. Also many of our top customers write this visual object themselves for pi tag data and use it in all sorts of process engineering improvement cases. Very fast way to find dependencies among attributes in a plant.

At this time, this item is not currently scheduled for a release of PI Vision. If this changes, this item will be updated to reflect the current status.

This is needed today to protect the intellectual property of what is inside in the analytic. This would be useful for "community" partners (equipment suppliers, engr service providers, consultants, etc..) to be able to distribute their expertise to PI System owners in a PI System analytic template. Users need see only inputs, outputs. Their logic is proprietary. An example case would be vibration monitoring service providers triggering EFs at plant site for site operators to qualify the incident and interact with the community partner. Community PI AF authors would greatly enhance existing pi system investments and be a welcome boost to site activity, strengthening data leaving the site to cloud based sharing and research.
