Yeah, it's a pretty neat ecosystem. PLCs are kinda like the Legos of automation, incredibly easy to mix and match with a fair number of (insecure) standard protocols.
I briefly toyed with the idea of building out some open source hardware/software but I didn't really seem like there was enough of a userbase to make it viable. Anyone using it professionally wants support and 10+ years of parts, most maker/hobby projects want direct access to code.
Still some pretty neat concepts for putting together highly customized processes with extensible and interchangeable hardware.
- high_byte 5y agoif you show them how insecure their current hardware is, it will sell. if it supports the old protocol but secure it should be transparent to them
- mikewarot 5y agoYou don't understand how industry works. If it works, you don't replace it, you get it fixed when it breaks. Nobody is going to willingly risk their factory, plant, etc. on some new supposedly better hardware. They'll keep what works going for 100+ years if they can. It is totally logical for them to do so. The "security" threat can be band-aided over with a new firewall at the internet access. Replacing any component of the control system introduces an element of risk. Downtime is horrendously expensive, and can ruin a business. Only a fool would do anything to introduce the risk of downtime in the name of "efficiency".
