xbee capabilities

I was wonderinf if the xbee systems could be used to control several (20+) devices? All will have an arduino embedded in it to control the machine. Right now, we have 15 wires running to each machine. I want to just have 4. (3 phase power and a ground) with a DC power supply for the arduino and a transformer for the 110 vac control voltage. I am still in the thinking stage, no prototype yet. Oh and all will come back to a single arduino and be controlled over ethernet. Its a big project if I get some idea if it would work.

It depends on the bandwidth you require. How often do the messages occur and how long are the messages?

In an industrial environment I would be more concerned with noise, EMI and transients. I think you would be better off with an industrial PC or industrial embedded computer. A device that is designed for machine control.

The messages would not have to be very long, example start emergancy retract from main system wait for finish, or fault next device.

And this would happen about every 3 to 5 times per day(24 hours) It is all located outside too.
