just spend 2 hours reading what Modus is...
I can say that I don't have one! sure want one!
On the VFD is no RS485 , so the only think to do using a modbus with analog input card.
a pitty.. I have 3 LPT ports in my PC I can use, and still have left over inputs, which it would be so simple I could just use one of those
