ISA Standards: Update on security, hazardous area equipment, EDDL

Recent standards developments at ISA include ISA99: Security for Industrial Automation & Control Systems, ISA12: Electrical Equipment for Hazardous Locations, and ISA104: Electronic Device Description Language (EDDL).


Recent standards developments at ISA include the following.


ISA99: Security for Industrial Automation & Control Systems

. The ISASP99 committee has made substantial progress on several fronts in its work to develop standards and guidelines for the electronic security of industrial automation and control systems.


ISA12: Electrical Equipment for Hazardous Locations

. ISA has published ANSI/ISA-12.12.01, "Nonincendive Electrical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) Locations." The standard provides minimum requirements for the design, construction, and marking of electrical equipment or parts of such equipment for use in Class I and Class II, Division 2 and Class III, Divisions 1 and 2 hazardous (classified) locations.


ISA104: Electronic Device Description Language - EDDL

. An ISA technical report supporting Electronic Device Description (EDD) interoperability has received final approval from the American National Standards Institute (ANSI). ANSI/ISA-TR61804-4 (104.00.02)-2007, Function Blocks (FB) for Process Control - Part 4: Electronic Device Description (EDD) Interoperability Guideline, is the official United States adoption of the International Electrotechnical Commission (IEC) technical report of the same title.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
