Swirling flavors and sounds of New Orleans' culinary and musical icons will be briefly rivaled when ISA Expo/2000 and IMS Expo 2000 co-locate to host a technological smorgasbord of 750 exhibitors and a symphony of conference events for about 28,000 guests here on Aug. 21-24.Sponsored by ISA, the international society for measurement and control (Research Triangle Park, N.
Since its inception during the 1500's, the violin has undergone very little change. Strings and bow still work together to perform vital functions that allow a musician to keep the instrument strumming in tune. Like the strings of a violin, data acquisition (DAC) hardware devices perform vital functions in many industries.
Already facing several choices when choosing a fieldbus network, engineers now have another—Ethernet. Yes, that's the same Ethernet IT uses to connect PCs to the enterprise and ultimately the Internet. Well, it is almost the same.In the face of all the other fieldbuses with vendor groups, big company support, technical committees, and compliance testing, why is anyone looking at Eth...
Dick Caro officially tendered his resignation Feb. 1 as convenor of the IEC SC65C/WG6 fieldbus committee. With the recent passage of the IEC ballot on the final draft of the IEC 61158 fieldbus standard, he fulfilled his agreement to finish work on WG6. Mr. Caro had led the subcommittee since 1993.
Weaving enterprise optimization from the plant floor to glass house and through the supply chain requires sorting through difficulties, weighing options, and eliminating confusion. Related solutions and user and vendor recommendations are included in AMR Research's (AMR, Boston, Mass.) Oct. '99 Report On Manufacturing titled "Variability: The Cure is Out There," written by AMR's research...
What's next? Let's get back to automation and controls now that we've survived Y2K. I admit I enjoyed watching the world throw a lot of time, talent, and money at a global challenge. It was supposed to be Yawn2K, and it was. Now let's apply our efforts to the next global problem to be solved.
Here We Go Again.
Control systems are in another evolutionary period. Usually this remark is taken to mean a technology leap in the controller. The complete system, however, is more than just the controller, and changes are occurring in every part of the system. As Control Engineering covers these changes during the year, it is useful to look at each product and subsystem in contex.
Regular users of Control Engineering Online have no doubt noticed by now a significant change in the look and feel of the web site. It has undergone the most significant redesign in its history to better serve the steadily growing number of people who visit www.controleng.com to keep up-to-date on happenings in the automation and control industries.
Can you hear it? It's the sound of several thousand fed up sensor and transducer manufacturers doing an end-run around the endless fieldbus squabbles. Many are beginning to use increasingly intelligent devices and common communications, which can access networks and function on the Internet to get jobs done.
