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
