Emerson Exchange Day 2 - Intrinsically Safe CHARMs

Oct. 27, 2011

Peter Zornio, Emerson Process Management chief strategic officer, reviewed Emerson's responses to two challenges it sees its customers facing in process industries—increasing complexity of systems coupled with less experienced employees.

Emerson's responded a couple of years ago with its Human Centered Design initiative one part of which is that all products must pass a usability review before release. Another response to complexity was a device product called CHARMs that feature I/O on demand and enable electronic marshaling.

Customer Bryan Beyer, acid operations manager for Southern States Chemical, discussed how using CHARMs in his new greenfield sulphuric acid plant saved the company time and money in completing the project. He noted it achieved several results including reliability, smooth technology integration, easy to understand system for employees, smooth I/O configuration, simplified troubleshooting, wiring cost reduced by 50%, quicker and cheaper I/O additions (use of Ethernet was a plus here), and a wealth of production data now available from the system.

Zornio then announced an addition to the CHARMs family--intrinsically safe I/O. With a built-in intrinsically safe barrier, these devices (pictured here) will drastically reduce cabinet footprint required for an intrinsic safety installation, not to mention all the benefits of configurable I/O. These are designed for Zone 1, Zone 0 or Class 1 Div 1 installation.

Bob Karchnia, Rosemount vice president of technology, updated the press on the latest advances in the Smart Wireless program. There are now 6,100 networks installed that have accumulated 580 million operating hours. Emerson currently has 17 products released with 9 more coming during the next year.

A side note from a personal observation of the week so far--outside of a private conversation I had with Walt Boyes and Jose Gutierrez about the status of the ISA100 committee on wireless there was no other conversation at all during the entire conference about those standards issues. Only that there were products and applications working in industry.
