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