Listen in: Articles with this designation include short sound or video bites that you can listen to for more information. Give it a try. Control practice: Why are PID loops so difficult to master? While there is some variation on the precise extent of the problem, industrial studies suggest that most people don't know what to do with PID loops. Perhaps one-third of such applications work reasonably well, which suggests that the other two-thirds are only adequate or worse. Must this be the case? Listen in: Wireless developments for Air Force may influence industrial applications If you think industrial wireless networking is tough, imagine if you had to design a protocol to tie together a group of Air Force fighters or UAVs in battlefield conditions. Current research to do just that may find its way into the next generation of industrial wireless instrumentation. DCS platforms: Control systems get small for broader applications Think small. That's becoming the message from some large DCS suppliers in an effort to reach smaller-scale users and to assist in lab and pilot plant developments. The bottom line: More companies can benefit from big DCS capabilities without the matching price tag. Listen in: New alarm management for electric utilities EPRI and PAS have released a new guideline for alarm management for electric power generators. The report builds on work done by Bill Hollifield and Eddie Habibi in their "Alarm Management Handbook," first published in 2006. Loop tuning: Handy pocket tuning guide is available free ControlSoft has released version 3 of its “PID Loop Tuning Pocket Guide.” Now 12 pages long, the guide has expanded its reference section on common controllers. Cyber security: Firewall device creates its own rules Creating cyber defense-in-depth often involves adding small firewall devices at internal levels of a control system. Now those devices can be smart enough to create their own firewall rules based on observation of traffic patterns. In Print: Globalizing process engineering Companies with plants scattered around the world have discovered the advantages of common control strategies from plant to plant. Implementation approaches differ, but objectives strike similar themes. Online: 7 critical things to know about Ethernet Before Ethernet gets to the plant floor, make sure you cover this group of pivotal elements. |
