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 ...

Threat groups who target operational technology (OT) networks have so far focused their efforts on defeating segmentation layers to reach field controllers such as programmable logic controllers (PLCs ...

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 ...

The programmable logic controller (PLC) is an important component in most modern automation and process control systems today. It's also susceptible to lightning-induced transients. To verify the ...

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

The question of when it’s most appropriate to use an RTU or a PLC has not faded with the continued rise of the PLC and the PAC (programmable automation controller). In fact, a member of the Automation ...

Programmable logic controllers (PLC) save time, money, and energy in process control systems. They simplify systems. A brief history of manufacturing processes sets the stage for how to use modern ICs ...

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