Because Control Engineering posts fresh content each business day, some articles posted later in the month don’t get as much time for exposure as those posted earlier. Therefore, articles are divided into two sections: Those posted during the past two months (May and June 2013) and those posted prior to May 2013. More about each article and links follow, along with links to the most-frequented Control Engineering pages during June 2013. A link to each article or page is provided.

System Integrator Giants of 2013 – The 100 firms on the System Integrator Giants list represent the largest system integrators of 2013, among the companies listed in the Control Engineering Automation Integrator Guide. In the survey, system integrator revenue is defined as automation integration services minus the cost of all off-the-shelf products: hardware, software, and equipment. The system integrators who responded to this survey provided information about engineering specialties, industries served, products integrated, associations/affiliations, and challenges from their industry.
Understanding SIS industry standards – May 14 – Process safety standards and practices are spreading from oil and gas and other energy-related industries to broader process industry applications. Here’s basic advice on how to make more sense of the numbers and acronyms [such as SIS – safety instrumented systems].
PID math demystified, part 2 – May 13 – You’ve seen the equations, but have you thought about how those elements work together? Part 2: Adding integral and derivative to the mix.
7 reasons to a consider a non-Ethernet industrial network – June 5 – Here are seven reasons non-Ethernet networks might be specified for an industrial project, to help determine if an Ethernet, fieldbus, or a device or sensor-level network should be considered.
Beyond automation: Humans as process controllers – June 2 – While automated control systems can keep our manufacturing processes running efficiently, new variables are entering into the production equation that are beyond what we can expect from PID. In an interview, Peter Martin explains forces pushing a return to humans as controllers to accommodate these changes, at least for a while.
How wireless networks are changing industrial environments – June 4 – IEEE 802.15.4 based wireless networks can be reliable, robust, and cost effective for many industrial, warehousing, and facility applications. These wireless networks transmit through walls and floors, reducing wiring and routing challenges, and making equipment placement more flexible and productive.
PID math demystified, part 1 – posted May 6 – You’ve seen the equations, but have you thought about how those elements work together? Part 1: The basic concepts and proportional control.
5 steps to select a basic switch – June 23 – A precision snap-action switch, commonly used to detect temperature, position, and liquid levels, is typically available in three models. Here are five steps to select the right basic switch for an application.
Process risk assessment uses big data – June 3 – Technology Update: Predictive, process risk assessment can use big data to assess risks dynamically and report automatically, empowering plant personnel to identify issues, taking necessary preventive measures to address them, avoiding a related shutdown incident or accident.
NASA becomes service provider for private space ventures – May 6 – After the Space Shuttle program closed, launching systems get a new life with new customers, with new requirements for monitoring services. The tricky side of measuring helium and nitrogen use calls for sophisticated flowmeters.
A straightforward maintenance strategy yields improved plant performance – May 4 – Moving from reactive to preventive maintenance helps Monsanto improve output and reduce costs at its Muscatine plant. Smart field devices and control valve positioners provide critical diagnostic data to reliability engineers, guiding their efforts.
Will your automation business survive, thrive? – June 6 – Accounting for engineers: Beyond engineering, system integrators and other automation and controls companies rely on non-operational skills, like finance, to stay afloat. Accounting can be obtuse, and a mid-market business can sink—unseen—into insolvency, without attention to key metrics, said Nick Setchell, CEO, Practice Strategies, at the CSIA 2013 Executive Conference. Video gives more advice.
Process safety: Managing process safety with flexible IO – June 14 – Industrial facilities should approach safety and security holistically by addressing critical requirements from the process control network to the perimeter of the plant.

How to lower PLC software costs – PLC vendors make much more profit from software licenses than they do selling hardware. Smart shopping can avoid some of those fees. Advice for lowering PLC licensing fees follows.
How to select a VFD – These guidelines dispel the confusion about matching variable frequency drives (VFDs) and motors to fans and pumps that are typically encountered in commercial building applications. While the motivation to increase energy efficiency could be financial (reduced energy costs) or ethical (reduced greenhouse gas emissions associated with power production), it is taken for granted that VFDs are an easy way to improve energy efficiency in a motor application. And with these noble intentions in mind, the engineer will specify a VFD for his client. Often, that isn't the end of the story for the engineer.
