I would love to see the Plus+1 units with the form factor of a typical industrial PLC. I've done over 20 Plus+1 systems and every one has been mounted inside a cabinet. We do this because connectors usually fail first, because there are always other bits involved (like fuses, distribution terminals, relays, operator controls), and because no one likes servicing a mud/oil/salt/manure/sewage/tomato (yes tomato) encrusted MC050.
Nice all-in-one breakout box Ian.
