content: In case you had doubts wether or not to use a Raspberry Pi for professional use or to integrate it into your product,this could be interesting:https://www.raspberrypi.org/blog/supporting-raspberry-pis-industrial-customers/"We’ve seen a large proportion of sales go into the industrial market – businesses using Raspberry Pi, rather than educational settings or individual consumers.""The industrial market for Raspberry Pi has grown over the years, and now represents around 44% of our annual total sales.""As part of our commitment to industrial customers, we guarantee product lifetimes until at least 2026 on all products."

content: These are Pi based...https://ukdepartureboards.co.ukNot sure if they ever sold much outside of the enthusiast market though.

content: Quote from: JohnnyMalaria on January 04, 2021, 08:51:54 pmGreat, but does it have any real safety and reliability certs like the real stuff? Or is it just "if it looks like an industrial PLC it must be an industrial PLC" type of thing? How about ESD/surge immunity? Failsafe outputs? Does the outputs fail safe if the CPU stalls? etc.. There is a lot more to an industrial grade controller, than just a CPU with some IOs.Clicked the first link and the main feature mentioned seem to be an 8 layer PCB.Would be more interested if itis compliant to for example IEC61131-2, rather than how many layers the PCB has.

content: Good then, am surprised.But what is the end market for that thing? Why would one want an RPI in a PLC?

content: The network stack!VNC is useful is come contexts. I don't know that it will be useful for a PLC but it would remove the requirement for the programmer to install software on their own workstation. Level playing field, everybody uses the tools provided on the Pi. There could be some very informative screens available over VNC.The concern I have is that Linux is not a real-time system. There are a number of notable attempts to make it so but I haven't followed them. This would be more of a problem for motion controls. Simple ladder logic is usually run as a super-loop.I'm not terribly excited about Bluetooth LE but that's another area where the Pi might be preferred. It would allow cell/tablet control of various systems. Probably not those that could harm people but perhaps access control, environmental control and things like that.
