OSIsoft is excited to present a brand new utility called the AF Transfomer.


The AF Transformer can take one or more source AF structures, reshape those structures and then write them to another AF destination.  This can be useful when you have one or more AF reference structures containing enough meta data to be able to shape into other AF structures that benefit other users and use cases in an organization.  We have found many organizations desire different AF structures for different purposes.


Example transformation where a new parent element is created from an attribute:

One use case that comes up regularly is for transforming the AF structures built by PI Connectors.  The source AF structures built by PI Connectors can serve as a useful model for the PI Admin and controls engineer to confirm that the right data is being collected because the AF structure looks exactly like the data source's meta data.  However, the shape of data coming from data sources often does not fit perfectly the way an organization or end user desire to consume the data.  Hence, the AF Transformer can help.


You may have seen this at the London UC where we showed a few examples during this talk.  Forward to about 14 minutes in and the next 10 minutes cover the basics of what problem this tool helps you solve and then gives a few demos.  Feel free to watch when you have a few minutes. Additionally, we will follow this blog with some more detailed examples for you to learn from.  There are plenty of examples (including source AF databases to transform) installed with the utility.


We'd like the community of developers, partners, and customers alike to share their questions, their successes and maybe a few examples of what they create in the Developers Club community.  Stay tuned for more content from us and in the meanwhile, we look forward to your questions, comments, suggestions, and successes!


Download the installation kit, user manual, reference guide and release notes at the AF Transformer group site on PI Square.  The group is a private group but we are glad to give you access!  Just click this link, request access, and we will approve shortly and notify you when you have access.


And here's a very easy hands-on tutorial!

Today at OSIsoft's vCampus Live! conference we are announcing a milestone for our Event Frames initiative:  the release of the Community Technology Preview (CTP).


All the details of the CTP are in this document.


Event Frames is a new data type that is useful for storing events such as downtime, startups, environmental excursions, as well as batches.  In fact, any event with a start and an end time and other optional data (like the asset, or operator, or comment, or lot number) can take advantage of Event Frames for its storage.  Just like AF Elements provide context to the time-series data streams, Event Frames provides context to the actual time-series data.  For example, you can look up your last 5 equipment startups and use those times to see the associated time-series data.


This CTP milestone is our first release of Event Frames outside the walls of OSIsoft.  It provides the database, programmatic SDK, and management tools (PI System Explorer) for you to get started. See how you can use Event Frames in your applications.  As we progress to our next milestone, we'll post examples, thoughts and of course announcements here on this blog.


Have a question, a comment, a success story?  Please visit the Event Frames Development discussion forum and post it there.


We're looking forward to hearing your feedback!
