A Single Dashboard into Digital Field Devices with EDDL
Emerson's Dale Perry and Jonas Berge teamed up for a look at EDDL (Electronic Device Description Language) technology from a pressure measurement device perspective in a recent Industrial Automation Asia article, Pressure Transmitters: EDDL Equals Easy. Their...
Demonstrating Safety Instrumented Functions with Foundation Fieldbus
You may have seen some of the coverage of last week's Foundation for Safety Instrumented Functions (SIF) End User Demonstration (DeltaV News, Sound OFF! blog, and ARC's Larry O'Brien's blog to name a few.) This event highlighted demonstrations of Foundation Fieldbus...
Comparing EDDL and FDT/DTM Communications Enablers
I had the opportunity to visit with Emerson's Tom Wallace who was here in Austin recently. I like to joke with Tom that a post I had done with him comparing and contrasting HART and Foundation fieldbus caused such a stir, that it produced one of this blog's highest...
EDDL Supports Automatic OPC Server Configuration
Emerson's Jonas Berge is an active member in the ISA SP104 committee, responsible for advancing the Electronic Device Description Language (EDDL) standard (also known as IEC 61804-3.) You may recall Jonas from earlier EDDL posts. This standard creates interoperability...
Redundancy at Multiple Levels in WirelessHART Device Networks
Courtesy of Emerson's VP of wireless technology, Bob Karschnia, I received a draft copy of a whitepaper circulating about redundancy in WirelessHART device networks. It's not yet finished so I don't have a link, but here are some of the key thoughts I gleaned from it....
OPC and WirelessHART Paths to Standards
I read Dick Caro's, Which Way Wireless article published last Friday on the ControlGlobal.com site. It discusses WirelessHART and ISA100.11a and their paths to standards. He describes ISA100:ISA100.11a is the name of the first standard being developed by the ISA...
The EDDL Standard Keeps Advancing
I recently joined the Electronic Device Description Language (EDDL) mailing list to follow the work of this important standard. For those not familiar with this standard, EDDL.org describes it:Electronic Device Description Language (EDDL) technology is used by major...
Response to Foundation Fieldbus and Profibus PA Cost Comparison Whitepaper
Update: This post is from originally from 2008. It recently came up in an "archived tweet" message. The "fieldbus wars" have cooled considerably in the time between the original post and now... thanks for stopping by! ORIGINAL POST: In the early days of Foundation...
Discussions around EDDL and FDT
Automation World magazine's editor in chief, Gary Mintchell, wrote a post yesterday on his Feed Forward blog. The post, The Saga Continues - FDT v EDDL describes some of his discussions with people involved in both groups about the relative merits of their respective...
Peering into Your EDDL-based Field Devices
Advancing industry standards remains a vibrant activity in the process automation business. These standards foster faster market acceptance of new technologies by providing interoperability among many suppliers' devices compliant to the particular standard. InTech...
Calculating Foundation Fieldbus Segment Loading
When engineering a project with Foundation fieldbus, one element to consider is the electrical loading on each segment. I received an email the other day asking:...to find required formulas to calculate FOUNDATION FIELD BUS loading... I am using [brand X] product and...
