      I’m failing to establish a connection between HMI Draw and my Unidrive SP Drive.
      The Unidrive SP supports only a ModbusRTU via a RS485 connection. This is achieved via a Wifi to Serial Converter, the USR-WIFI232-610. I was able to establish a serial RS485 connection with the converter, as well as ModbusTCP connection with my PC. The USR-converter supports a ModbusTCP to RTU conversion.
      But whatever combination of possible settings i try, i can’t hook up HMI Draw to my Drive.
      HMI Draw connects for ~6 secs and then states an error like “No answer from the remote host. It stopped responding or the network went down”.
      Is it possible i understand the PLC Tags settings fundamentally wrong so i can’t read the Unidrives Register?

      Thank you for any help.
