Annotation/Comment on Data Values
Be able to enter and visualize user comments made on a attribute/tag data stream.
Indeed, this would be an extremely useful facility to have! I concur with hooper's comments.
Susan Stoner commented
We would use this for PIML points to display the person who entered the value. Displaying the "Inspector" is needed for NERC compliance.
Currently we are using PI DataLink but PI Vision would be much better.
Jeffrey Gardner commented
We (big oil) also need a way to annotate trends using PI Vision. We currently use ProcessBook but want to switch to Vision.
Cameron Lee commented
We are using Pi manual logger to record plant readings and use the annotations to record discrepancies. Being able to see these annotations historically is of great value. Besides if you are going to roll PI Manual Logger into PI vision, you’ll have to do this anyway! 😃

I agree. While I understand annotations can be added to Event Frames, engineers in my company often annotate PI Tags to explain data anomalies both slight (difficult or not worth capturing via event frames) and major (that do generate Event Frames). We deliver our PB 'dashboards' to many users via Coresight as Coresight performs much better on mobile devices and regional offices where internet connectivity is not a good as at the corporate offices (PI headquarters).
Our users rarely visit Event Frames as all the data they need is available in the PB dashboard. The fact annotations are absent in the Coresight view discourages use of Coresight.
We had implemented this feature with an plugin for PB. It would be great to have this feature (and if possible the Support for 21 CFR Part 11 Electronic Signatures)
