From my experience with PLCs, they are hardened and robust to the extreme degree required by the harsh environments in which they are used. Last time I looked, the R Pi was the complete opposite. It can be crashed by just a nearby camera flash, and then leave its SD card corrupt to boot. Fine for hobbyists (apparently). Not fine for industrial applications.
- bongodongobob 2y agoRight, I'm not suggesting they replace critical PLCs. They are overused in places where those requirements aren't necessary just because PLCs are what their engineers know.
- alangibson 2y agoCompute Modules are targeted squarely at industry. Environmental hardening is provided by the cabinet you install them in. I built an RPi 4 based plasma cutter and I've never had a crash. You don't get more EM interference than that, short of putting it in a microwave.
