      Could someone enlighten me as to what the following two error messages may mean when polling a modbus TCP/IP data register?

      1.Gateway path unavailable
      2.com.serotonin.modbus4j.exception.ModbusTransportException: java.net.SocketTimeoutException: connect timed out

      Thanks in advance,
      Dominic.IRL

        Both of these look like the device didn't respond. Do you get these all the time or just once and awhile. If things generally work and you get these just once and awhile I'd say that's fairly normal for modbus devices.

          Hi Joel,

          It's more trial and error shifting Mango onto cloud based server at the moment. The two different errors were coming up when trying two different ports for comms. I have port forwarding set up on my router for two devices. I was just wondering why one port got one error and the other port the other error. I have yet to establish communication with the Modbus devices but this is a network issue - nothing to do with Mango as I have found out.

          Rgds,
          Dominic
