Thanks mrprecise44
I will take a look at the Cubloc.

Also look at the click plc.
Very cheap and supports Modbus too.
I have one, have had it talking to Mach3, but have not had the time to do anything else with it.

Hello Mike:
I remember you posted about the "Click" a loooong time ago, and I did look it up after reading that post . A nice little unit as I recall, but after looking at all the Cubloc stuff, I choose that particular brand.

Just too much cool stuff out there.
