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 ...

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 ...

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 ...

Programmable Logic Controllers (PLCs) and Programmable Automation Controllers (PACs) are industrial computers built and adapted for manufacturing environments. These are the brains of a manufacturing ...

For a plant-based document destruction 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 ...

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

This article originally appeared on July 3, 2019. Packaging lines are well-known examples of multi-programmable-logic-controller (PLC) operations. There are PLCs on the conveyor lines, which may or ...
