Hello!

I set up the ModBus and everything is all green and happy.

Then I go into the Control Configuration / Input Signals and the drop down for devices has my ModBus, great! I select it. Then I click on the Input Name and I get an empty list.

What am I missing? I can access the values via scripts but I really want them as first class Input Signals and I can't seem to get it to work.

Thanks for the help!

OK, what is missing from the documentation is that ONLY coils and discrete i/o can be used as I/O for Mach4.
