  • Where to Focus to Drive More ROI from a Digital Twin Simulation

    Jim Cahill
    As manufacturing organizations embark upon their digital transformation journey, an essential starting point is to implement a digital twin. Digital twins deliver value in project execution with easier engineering and testing. When the project is over, the same digital twin enhances daily operations, improving safety and uptime by moving training and process change testing off physical equipment and on to a digital workspace…

  • Building More Defendable Control and Safety Systems

    Jim Cahill
    A plant’s basic process control system (BPCS) and safety instrumented system (SIS) are critical infrastructure for the facility. Many decisions go into selecting these systems, and one of the most important is selecting the right architecture—a decision that will impact other elements of system selection as well as performance and efficiency across the lifecycle of the equipment. One key decision that will impact automation…

  • Three Things to Do, and Three to Avoid, When Assessing Your Cybersecurity Situation

    Jim Cahill
    Any process manufacturing company that has not yet launched a cybersecurity program is probably frozen in a frequent difficult position: Where do we start? If your company is trying to break free and make some progress—and maybe you’re the one tasked with doing it—we have some suggestions for critical first steps. These suggestions are included in our article in the September issue of Control Engineering . The key point…

  • Selecting the Right Automation Architecture

    Jim Cahill
    Creating a safe and secure automation process starts with implementing a well-designed basic process control system (BPCS) and safety instrumented system (SIS). Government agencies and industry associations offer guidelines and requirements for how these systems should be connected and separated—most importantly with the requirement that the SIS and BPCS should be logically independent regardless of the level of physical…

  • Multiple Systems Working Together Prevent Tank Overfill Disasters

    Jim Cahill
    In Hydrocarbon Engineering’s Tanks & Terminals Supplement , Emerson’s Helena Hjortsberg looks at all the elements of a comprehensive overfill prevention system in her article, A Coordinated Strategy. Overfilling a tank storing hydrocarbons or other flammable chemicals can cause an environmental incident under the best circumstances, but also a high probability of an explosion and fire. Given the costs in lost product…

  • Hydrogen Sulfide in Paper Mills: Find it Before it Finds You

    Jim Cahill
    In a Paper360 magazine article, “Wireless Sensors Improve Toxic Gas Mitigation in P&P Mills”, Emerson’s Forrest Francis explains how workers can avoid nasty surprises. TV shows add drama saying their stories are “ripped from the headlines,” meaning they’re based on real-world people and events. Sometimes the same thing can happen with articles. The real-world story in this case was a report from Australia about two…

  • Non-contacting Radar for Automatic Tank Gauging and Overfill Prevention Systems

    Jim Cahill
    Bulk liquid storage tanks often contain fluids that are hazardous, flammable and/or explosive. These tanks require not only a control system to control levels but and overfill prevention system (OPS) as layer of protection beyond the control system. This basic process control system (BPCS) is commonly referred to as an automatic tank gauging (ATG) system and the OPS is the safety instrumented system (SIS). A Fluid Handling…
