These 100 firms represent the largest system integrators of 2012, from among 2,334 in the Control Engineering Automation Integrator Guide.
Sure, the idea of “iPhone as HMI” is convenient, but it opens a whole new range of cyber vulnerabilities. Is the functionality worth the risk? Many users are already deploying the technology without sufficient safeguards.
Back to Basics: Knowing why, where, and when to apply pneumatic actuation improves performance and efficiencies and lowers cost.
Product Exclusive: Eaton XC controllers with Controller Development Software (CoDeSys) advance lean automation with powerful, modular systems for open, scalable, and high-performance control.
Industrial HMI developers consider how video game technology can change the way operators work with control systems. Video: ABB demonstrates some interesting possibilities.
Wireless technology has limitations, but like any technology, it is very powerful when properly applied. Consider these factors before implementing wireless devices, including power, response time, and range, among others.
Safety PLC, adjustable speed ac drives, motor starters, and energy management software from Rockwell Automation, along with EtherNet/IP communications from ODVA helped reduce downtime and cut costs.
Choices of controllers that include an integrated HMI in one package are growing. These promise greater simplicity if the combination of elements works in your situation.
Control Engineering Engineers' Choice Awards highlight some of the best new control, instrumentation and automation products as chosen by Control Engineering's print and online subscribers. Survey respondents are asked to select products based on technological advancement, service to the industry, and market impact.
