How Ethernet is inexorably claiming its place as the plant nervous system.

CG1602 IndustrialEthernet

Oh sure, Ethernet is just a cable and some software, but pretty much anything and everything can happen on it—and happen fast—and that's its main attraction. At its most basic, Ethernet connects computing devices, establishes local area networks (LANs), virtual LANs (VLANs) and wireless LANs (WLANs), and runs multiple digital communication protocols, mostly those based on Transmission Control Protocol/Internet Protocol (TCP/IP). Of course, this makes Ethernet the backbone of most modern, mainstream, IT-based, wired and wireless networking, which underpins most if not all digital and Internet protocol (IP) communications, virtualized computing, cloud and software…

Questions What is being done to protect the malware-vulnerable programmable memory of the PLCs of critical facilities? Anything? It is possible to program a PLC memory and then program a lockdown so the memory becomes write-once rather than write-always, and thus would be immune to malware attacks.
