Experts disagree on whether the vulnerabilities in a programmable logic controller from Delta are a five-alarm fire or not ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

For many years, factories have used PLCs for automated control over industrial equipment. These systems are usually expensive, proprietary, and generally incapable of being reprogrammed. [Oliver], an ...

This tutorial offers an in-depth introduction into programmable logic controllers (PLCs). The article starts with an overview of the history and the role PLCs in factory automation. The basic ...

Programmable logic controllers (PLCs) have become the most popular and efficient way to control manufacturing equipment. Replacing the older style of hard-wired control relays, PLCs can be configured ...

Programmable logic controllers (PLCs) that were vulnerable to the Stuxnet attack are still in use globally and rarely have security controls deployed — meaning they're still at risk. More than 10 ...

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 ...
