Industrial computer networks are very similar to standard computer networks; most of them use TCP/IP and ethernet, on x86 hardware, with some Windows-based or browser-based workstations or kiosks.
But, industrial systems have their own set of acronyms, protocols, requirements, and history. Security concerns, plus a desire for tighter control, are forcing SCADA networks to upgrade; many of these networks still run Windows NT 4.0. Linux is, as usual, the perfect solution.
I will discuss some of the industrial deployments I've seen, with a focus on how Linux was used, give a brief overview of current Windows-dominated SCADA packages, and describe how Linux can be used in new SCADA / HMI deployments.
