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 ...

Control systems are the backbone of a modern automated manufacturing plant, but their longer-term value lies not just in the moment-to-moment control, but in the deeper evaluation of how systems ...

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 ...

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

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