In process industries like oil and gas, chemical, paper, and water treatment, precision is everything. That’s why PLCs—once simple relay replacers—have evolved into powerful, real-time control hubs capable of enabling intelligent operations across increasingly connected systems. To explore how PLC technology is transforming process control, we spoke with Jeff Payne, Director of Business Development at…

Automation of a Pilot-Scale Distillation Process
Applying large-scale automation concepts and technologies to a small-scale process operation. By Doug Reneker Small-scale distillation processes can take many forms because there are countless possible objectives, but the underlying principles reflect those used by large-scale companies to produce fuel, chemicals, and alcoholic beverages. Boutique and hobbyist practitioners creating products worthy of aging and imbibing…
By: Rin Irvin and Josh Waters It’s an engineering truth that there’s no such thing as a perfect solution, just the best solution for the project at hand. This principle remains true for process control applications. PLCs are powerful and comprehensive control solutions, but not every industrial process needs that level of functionality. For every…

Cooking Up a Partnership
A system integrator supports their food processing client, implementing industrial automation technologies for a mix of OEM equipment and systems throughout the facility. By Jordan Hulsey, Caldwell Electrical Contractors, Inc. With busy lives and schedules often bursting at the seams, ready-to-eat (RTE) food has become a convenience that many indulge in—and some may even rely…
Closed-loop PID control is indispensable for a myriad of automation applications, and designers need to know the options for implementing PID using either dedicated devices or automation controllers. Automated regulatory control of characteristics like flow, level, pressure, temperature, and many other types of analog values is essential for countless types of machinery, processing equipment, and…
This OEM systems integrator has standardized on a common touchscreen user interface, improving their ability to create automated equipment for their clients. While automated equipment ideally runs itself, there remains a need for humans to interact with machinery for setup, monitoring, troubleshooting, and more. This role was once fulfilled by buttons, switches, lights, and the…
Anyone who has ever observed a modern factory in action, whether in person or perhaps via an episode of the “How It’s Made” documentary television series, is aware of just how impressive machine automation can be. This is especially the case when witnessing robotic arms and other machine motion control, as mechanical apparatus and payloads…
This home-built robot was created with industrial-grade automation technologies, providing a unique platform for learning career-enhancing skills. Inspired by science fiction movies featuring robots like R2-D2 and WALL-E, Justin Flynn, a controls engineer, embarked on a journey to build a personal animatronic robot named Hubert Evolution 2 (HEV2), reminiscent of Johnny 5 from the 1986…

Automated Robotic Welding Cuts Production Time by Over 90%
A manufacturing company teamed up with a systems integration firm to significantly accelerate an infrastructure project by integrating a robotic welder with precision motion control, intelligent safety systems, and other advanced automation components. Tasked with producing over three miles of steel fencing in just 90 weeks, a leading steel fabrication company knew it needed to…
Pilot devices are essential operator interface components for most automated equipment and processes. As the industrial age dawned, machinery and equipment were controlled manually by operators pulling levers, turning hand cranks, and making similar actions and adjustments as they saw fit. Industry 1.0 was powered by water and steam, 2.0 relied on electricity and added…
