The December issue of Control magazine is now online and ready for viewing. It features our annual rating of the Top 50 automation companies, both globally and in North America.This year, vendors are all doing well, but are nervous about the future. We also discover how Schweppes Australia sweetened soda pop production by consolidating process and logic controls and why your sampling systems need a lot of love and attention. And don't miss our regular columnists, John Rezabek on fieldbus, Bela Liptak and friends answering process control questions, and Jim Montague exploring an electronic marshalling project.

The October issue of Control begins with a view of real-world security in process automation, discussing how real companies are addressing the complex issue of securing their operations. It goes on to explore a systematic way to herd all those variable “cats” and achieve plant-wide control, how Iggesund Paperboard uses data-logging and supervisory control software modules to simulate and control pulp and paper production and predicatively control pH levels, and how the FAA uses ultrasonic flowmeters to regulate the cooling of vital high-powered computers.

Control's September cover tells how automation can cut costs through the lifecycle of a plant asset. Also read how desert-country water districts conserve this increasingly scarce resource, plus more on optimization, VFDs, Fukushima's implications, buses for final control elements, and smart I/O.

Control's July cover story focuses on "Tribal Knowledge" and how new tools are preserving vital process know-how

In the June cover story we profile companies that have taken "going green" well beyond improving production efficiency and into cutting-edge sustainability programs. We also show you the results of our 2011 salary survey and analyze the reasons why you should consider Intrinsic Safety applications for your facilities. All this, plus out experts take on control valves that also measure flow, and Control Talk's McMillan and Weiner look at more inventive PID applications.

Our February issue features the latest three inductees into the Process Automation Hall of Fame. Check out whom these "Masters of All the Tools: are. Then, find out about the fieldbus "black channel," the best application for difficult level-measuring challenges and the basics of analyzer sample systems. Also, don't miss our great columns, Control Talk, On the Bus, Other Voices and Ask the Experts.

The January issue of Control showcases our 19th annual "Readers' Choice Awards," wherein readers pick their favorites among more than 100 process automation categories. Also in this issue: How to hijack a PLC; how to keep your head above the big wave of smaller, faster, cheaper, stronger industrial PCs flooding into the market; and our regular columnists covering fieldbus, alternative energy and process automation, and the advantages of the virtual plant.

The October issue of Control focuses on the new security risk called Stuxnet in out cover story called "Worst Fears Realized." What should you do to protect your control systems now? Other stories feature the latest in OPC security, Fluor's use of Coriolis flowmeters to fast-track the development of China's largest solar-grade polysilicon plant, the use of simulation in design, training and operations. Plus, Ask the Experts, Control Talk and On the Bus and you other favorite columns.

The September issue of Control is packed with features. We cover the breakout of simulation from the realm of design; configuration and training and into optimization, model-predictive control and other plant-floor functions. We also explore the use of wireless gauge monitoring at the Vermont Yankee nuclear power station optimizing asset management procedures and why your CFO loves VFDs. And process control expert Bela Liptak takes on designing a control system to manage the global economy.
