Common questions about the distinctions between PLCs and SCADA systems, their integration, and the differences between SCADA and Distributed Control Systems. How do programmable logic controllers ...

If you go back long enough, before programmable logic controllers (PLCs) were around, we had relays, timers and electric loop controllers. Process control systems were highly distributed and hardwired ...

Embedded processors handle the rising complexity of automation tasks by employing architectures that are quite different from those of programmable-logic controllers. It is no secret that ...

The modern programmable logic controller (PLC) is at the nexus of two debates that are taking place daily at opposite ends of the control-system spectrum. At one end is the debate over the ideal ...

This file type includes high-resolution graphics and schematics when applicable. Historically, motion controllers, programmable logic controllers (PLCs), and industrial personal computers (PCs), which ...

For a plant-based shredding system to run smoothly and produce the desired tonnage, dozens of mechanisms need to be running correctly and in sync with one another. One misstep and the entire day could ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...

With integrated diagnostics and override functions, PLCs have become easier to use and much less expensive. Before the automotive industry discovered the advantages of programmable logic controllers ...

The following tutorial will explain how to transform the potential of popular microcontrollers into programmable logic controllers (PLCs). This primer is for those who want to begin learning about ...
