Here’s a sampling of the industry blogs I read over the past couple of days.

Jim Cahill’s Emerson Process Experts on Optimum Combustion for Reduced Greenhouse Gas Emissions. Actually, I bookmarked that one for information for an article on sustainability I’m writing for our March issue of Automation World. Thanks, Jim.

Jim was back later with Similarities and Differences in Fired Heater Safety Standards. He also posted Electronically Dispatching Work Procedures. The idea of promoting internal experts to the community is good marketing and a community service.

Greg McMillan continued his Exceptional Opportunities in Process Control series with Middle Signal Selection.

Eric Murphy at the OPC Exchange Blog writes about OPC UA’s adoption as a standard within NIST’s Framework and Roadmap for Smart Grid Interoperability Standards.

Speaking of OPC UA, I’ve been wondering about it versus OPC Xi — the standard built on Microsoft .Net that the large systems suppliers seemed to want for a quick fix to the COM/DCOM problems of classic OPC. There’ll be more coming after some press conferences Monday in Orlando, but the gist is that there will be a number of companies coming out with embedded solutions that will expand OPC UA into a number of new areas. So, if you are just updating your OPC communication from field devices and controllers to HMI or databases, Xi will get you there quickly. If you’re looking for additional opportunities for communication, stay tuned to OPC UA.
