  • Hi Lohbihler,

    I'm having this problem:

    'Serial 0': com.serotonin.modbus4j.exception.ModbusTransportException: com.serotonin.io.messaging.SendTimeoutException

    the modbus device is communicating...but the data is not shown

    What is wrong ?

    the most strange thing is that when I send a command to the device it recognizes the command, but the reading still does not work

    thanks for your patience

    regards,
    Mario


  • Couldn't say. Do you have traces of the communication between the two?
