Comment on Microsoft inks deal to restart Three Mile Island nuclear reactor to fuel its voracious AI ambitions
jadedwench@lemmy.world 6 days agoIt was the SCADA view right? A lot of SCADA software is basically running on top of windows, though you typically would never see the desktop. Ignition at least is cross platform, but that is because the server is Java and Jython. A big part of why things are running on windows is due to OPC, which was traditionally all DOM and .NET. It is basically a standard communications protocol and is what allows your HMI/SCADA to communicate with PLCs. Otherwise, you use proprietary drivers and native PLC specific protocols.
SCADA programming/design is kind of an art and is usually written by an either an overworked engineer or someone who had far too much time on their hands. You basically build screens using specialized software, hook up buttons and UI elements to PLC signals, and pass some signals from the UI to the PLC. They are all heading in the Edge/iot/cloud/web based/techno-babble direction these days…

“is usually written by an over worked engineer”
I’m in this post and I don’t like it.
But really these scada systems are rarely well defined by the time implementation happens. Often the architect has a great plan, but by the time it’s passed to a manager, a non-software engineer, to the product engineer to the automation team to the contractor the end result is “X data is pushed in With Y form and we use either a,b,or c date time stamp any nobody knows”
