Martin Villalobos Posted January 20 Report Share Posted January 20 I have been trying to connect PLC UniStream via USB in 485 ModBus RTU with an EATON DC1 frequency inverter, and I have not had an answer, does anyone know or have an example to be able to do it?

Connection parameter can not be changed. You must connect DI1 for operate drive via MODBUS. Please use PC modbus software and Usb-RS485 converter for test connection before try to use Unistream PLC.
