When Mark Nixon and I wrote Control Loop Foundation – Batch and Continuous Processes we also worked with Paul Muston and Deb Franke to create a web site that goes with the book. Anyone may go to this web site to perform the 19 workshops that are included in the book. When you select a workshop and then click on the workspace tab an on-line view of the associated control module is displayed. In the background is a full dynamic simulation of the process and the control modules. Thus, the on-line view closely duplicates what would be seen in a running plant. By clicking on a function block or parameter shown in the module (e.g. setpoint of a PID block) then you can change the parameter value and see the impact of this change. By selecting the Chart tab you can observe how the process and control change over time by viewing a trend of critical parameters in the module. Many people have found this environment helpful in exploring and learning about the basic single loop and multi-loop techniques that are used in the process industry.
Since the web site was created an averages of over 10,000 people visit this site per month. When Mark and I meet people who have used this web site we are often asked how the web site was created and what technology is behind the workspace and chart view. To address these questions, Mark Nixon, Paul Muston and I put together for Emerson Exchange, 2012 a short course titled The Semantic Web: An Inside Look at the Creation of Control Loop Foundation. Mark and I presented this short course two times at Emerson Exchange.
I received permission from the Emerson board to record the audio portion of the presentation. Using the tools available in Slideshare, I have combined the audio with the slides to create a video of the presentation. Thus, if you did not attend Emerson Exchange 2012 and would like to learn more about the inner workings of the Control Loop Foundation web site then you can see the slides and listen to the presentation using the embedded link below.
The total presentation is approximately 60 minutes in length. If you do not have time to listen to the complete presentation, then using the controls that are provided above you can skip to the portions of the presentation that are of interest.
