how are PLCs usually powered? is power over ethernet a dumb idea for that? (gruetzkopf? I know you have some industrial experience)

pie_: PLCs typically are powered from a nearby 24V DC supply in the same control cabinet. POE is Ok for remote I/O I guess, but at some point you have to pay the piper :)

For _small_ PLC applications where you know your power budget to fall with in desireable limits, I guess you could get away with POE...

Just my $0.02, I haven't touched IA/IE gear in a long while.

some vendors (Beckhoff comes to mind) Supports remote-powered IO, but that's not using 802.3 PoE - they're putting along one pair like a phone does
