I recently came across a PLC from one of our potential suppliers, and judging from the included runtime licence it runs on rpi.
Does anyone have any idea if/what environmental qualifications any of the PIs have? I couldn’t find even a temperature range of the PI itself, the end product is just marketed for rail market, nothing else in their marketing literature.
