There's a particularly horrifying story from a local dairy farm where a worker

spoiler

climbed into some kind of mixer to unclog it, didn't lock it out, and for some reason it was controllable via WiFi and the boss decided the mixer should be running.

Guy was like 30 with a small kids and his own farm, but had to work at this shitty dairy to supplement his income. Big farm in the area bought out his whole place within a few months of him passing.

WHY WOULD YOU WANT TO WIRELESSLY CONTROL HEAVY MACHINERY WHAT THE FUCK

[-] octobob@lemmy.ml 6 points 1 week ago* (last edited 1 week ago)

It's incredibly common in industrial automation to control things over networking. Usually it's an Ethernet connection to a computer or laptop interfacing with a PLC that's running code, but same idea. I've built and installed control rooms in steel mills, they're mostly computers running Siemens or Allen Bradley (Rockwell) software, monitors hooked up to cameras around the mill, and operator stations with push buttons, joysticks, lights, e-stops, etc. And plenty of HMI's (big touch screens). Think Homer Simpson's job

Networking is different than wireless.

Are least a cable connection means something is nearby. A wireless connection that can be accessed over WAN is what I was freaking out about.

You're not wrong, in mfg and similar I've personally only ever seen wireless anything used for measurement instrumentation, explicitly not control, and that was even using a more proprietary wireless than 802.11 / typical WLAN.

I've been out of those industries for a while and to be fair the ones I serviced were on the more expensive process side (which does translate to better equipment but even just better safety expectations), so idk how accurate my experiences are. But yeah wireless control was def considered unacceptably risky, your instincts are correct.
