Hi,

I have the UC100 controller and I would like to implement an MPG, FRO, SRO and so on for a control panel.

Can I add a LPT to usb converter and use it as port 2 (or any other port number)? My guess would be no.

Can I use an arduino as an interface and use Modbus?

Or do I have to buy a UC300ETH?

Thanks!

No, you can't use an LPT port. UCCNC does not support the parallel port, not even if it is a USB - LPT converter.
Yes, you can use Modbus but make sure it is REAL Modbus. UCCNC does have a Modbus plugin and that works well.
Buying a UC300ETH would be the simplest solution, but you need a license. I don't think you can "give back" the UC100 license and exchange to UC300ETH.

How would you assign inputs from a Modbus device in UCCNC?

I guess the same way as the VFD inputs.

Yes you can use arduinos- I tested 2 running perfectly for a week

Teh modbus READS are brought out to teh assigned Modbus Variables table and from there you use a MacroLoop to move them where ever you need them.
