Increasing Diagnostic Coverage in Safety Instrumented Functions
Two very knowledgeable people in safety instrumented systems (SIS), Mike Boudreaux and Riyaz Ali, shared with me the story behind the recent news about the DVC6000 SIS digital valve controller (operated by 4-20mA) being certified to be compliant with IEC 61508 for use...
Using HART Diagnostics in Safety Instrumented Systems
I read Siemens' Charles Fialkowski's latest post, Introducing a non-redundant, redundant SIL 3 solution? about their SIL 3 HART I/O card. He discusses how technology has changed where newer SIL-3 rated safety instrumented systems (SIS):...don't require redundancy to...
Online Statistical Techniques in Batch Operations
I was reading the great Control magazine article, Data Analytics in Batch Operations, by Lubrizol's Robert Wojewodka and Emerson's Terry Blevins. It describes the challenges in applying on-line analytics in batch production for early fault detection and prediction of...
Digital Valve Controllers in Safety Applications Get Smarter
In the world of process safety, technology continues to advance to assist process manufacturers in their IEC 61511 safety compliance efforts. I saw a recent press release on enhancements to the Fisher DVC6000 digital valve controller. The news was:...enhancements...
Successful Alarm Management Strategies Begin with Early Planning
My RSS feeds pointed me to a great ChemicalProcessing.com article on batch manufacturing alarms. The article, Rethink batch-manufacturing alarm systems, was written by Joseph Alford. He opens with provocative questions:Do operators sing the praises of your plant's...
Collaborative Initiative to Accelerate Process Development
In the upcoming March issue of BioProcess International magazine, there is a great article by Emerson's Greg McMillan and Michael Boudreau, Broadley-James' Trish Benton, and the University of Texas at Austin's Yang Zang. The article, PAT Tools for Accelerated Process...

Foundation Fieldbus Diagnostics and Advanced Process Control Screencast
In our continuing series of screencasts, I'm trying to give examples of how advanced diagnostics in Foundation fieldbus devices can be used in control strategies to avoid abnormal situations and potential losses in production. Emerson's Rune Reppenhagen shows in this...
Diagnosing and Switching Over Pump-Motor Trains
Here is another in my series of screencasts, this time showing how an automation system uses predictive maintenance diagnostics to switchover a pump before it fails. Emerson's DeltaV product manager, Randy Balentine, shows in this 2 minute, 43 second screencast a...
Using Advanced Diagnostics in Control Strategies
I had mentioned in an earlier post that short screencasts are a great way to quickly convery ideas in lieu of hundreds of words. One of Emerson's product application specialists, Rune Reppenhagen, graciously agreed to demonstrate how advanced diagnostics can be used...
Partial-Stroke Tests, Proof Tests, and Smart Positioners in Safety Applications
Before the holidays, Dave Harrold wrote a post, A Wee Bit More About Safety Instrumented Systems, in his Dave @ AFAB Group blog. He describes his work with Dr. Angela Summers, founder/president of SIS-Tech Solutions on a guidelines book for the global IEC 61511 safety...
