In today’s guest post, Emerson’s Jim Cushman, a member of the Power & Water Solutions business, looks at the process control architecture requirements for solar photovoltaic-based power generation. Early developers of solar photovoltaic (PV) did not consider the need to control the power generated from solar PV panels. In their minds, it was simply a [...]

You may recall from a post, Eliminating Temperature Effects in DP Level Measurement, a cool new technology—Rosemount 3015S Electronic Remote Sensors (ERS) system. To avoid some of the temperature and response time issues that I highlighted in the post with capillary tubing, this technology includes: Two 3051S pressure transmitter… mounted on the high and low [...]

Emerson’s Mike Boudreaux alerted me to a great article comparing safety instrumented system architectures. The ISA InTech article, Centralized or distributed process safety compares and contrasts centralized, distributed, and hybrid safety systems. Centralized systems have a single logic solver with all safety I/O routed and hardwired back to it. Distributed systems locate the logic controllers [...]

A colleague alerted me to a series of fun videos from the Rosemount Measurement team. The videos star Emerson’s Caitlin Breen and Daniel Lucey in the role of white lab-coated Rosemount 3051S Series instrumentation torture specialists. It’s one thing to say your products are reliable and robust. It’s another to show it. And that they [...]

Proprietary wireless sensor networks have been with us for more than a decade. The standards-based wireless network, IEC 62591 WirelessHART has now been available for more than 4 years. In an Industrial Automation Asia article, Choose Wireless Wisely, Emerson’s Jonas Berge describes some of the background and strengths of this wireless technology for the process [...]

You may hear the words internal faults, external faults, redundancy, availability, and reliability tossed about in discussions about control system architectures. Emerson’s Dave Denison, a software engineering manager in the DeltaV technology organization, wrote a great article, Architecture For Mitigating Effects Of External Faults: Choosing Tools And Techniques For Creating Fault-Tolerant Control Environments And Networks [...]

The language of process safety is filled with its own jargon. Architectures are described as 1oo1, 1oo2, 2oo2, 2oo3, etc. The “oo” means “out of”. So, 1oo1 means one-out-of-one. William M. Goble and Harry Cheddie wrote a book, Safety Instrumented Systems Verification – Practical Probabilistic Calculations, to explain how to do probabilistic calculations based on [...]

BayCHI, the San Francisco Bay Area chapter of the ACM [Association for Computing Machinery] Special Interest Group on Computer-Human Interaction (SIGCHI) held a BOF (birds of a feather) session on usability engineering. This session featured a presentation, Human-Centered Design in Action, by LUMA Institute’s Pete Maher and Emerson’s Jay Elkerton. Pete is the chief operating [...]

Performance Without Compromise Seminars

Across the Asia-Pacific region, a series of Performance Without Compromise seminars have occurred over the past several years. The name of the seminar series comes from former Emerson CEO Chuck Knight’s 2005 book, Performance Without Compromise: How Emerson Consistently Achieves Winning Results. These seminars highlight ways to improve plant performance and are a fusion of [...]
