Rugged, Small, Inexpensive CANopen PLC?
Does anyone have a suggestion for an inexpensive but rugged PLC capable of CANopen master communications out of the box? I am designing a CANopen based electric vehicle conversion and I need it as a master alarm handler, a safety device as a backup to individual component safeties (in the event that a BMS fails to open it's DC contactor, for example) , as well as a data aggregator and interface to the infotainment system / HMI. It need not be particularly fast but it should be well-sealed and preferably use open authoring software or software I can obtain inexpensively. Microcontroller-based approaches are acceptable but something that programs in CODESYS or something IEC 61131-ish is preferable.
The best solution I can find so far is a Raspberry PI in a potted and sealed enclosure, but i'm sure better solutions exist.
[EDIT] I should also mention this is a personal project and not a product for use by the general public, so I am OK with a certain latitude as far as using devices certified to be fit for purpose to industry standards because I know those type of standards are expensive to obtain and any product I could get inexpensively might not be SIL2 rated, for example.

Almost certainly out of your price range but the Bedrock OSA Remote is everything you are looking for. PM me for more info.
I have had some curiosity about Bedrock stuff for a while now, seems like you guys are the only ones really taking security seriously in the PLC world. I hate to PM because it always annoys me seeing PMs in other threads and not having the information. I see some press release stuff in google searches that puts starting price around $2900-ish. No need to sharpen the pencil any further than that, but is that in the ballpark?
Yep, I'm no sales person so I don't know what the real price would be, but that's probably pretty close.
