Hello,

my Environment:

  • openhab 3.3 (openhabian) on raspberry pi 4
  • usb serial adapter for modbus

what is working:
modbus tcp connection to solar inverter is working without problems

enabled log for:
log:set trace org.openhab.binding.modbus
log:set trace org.openhab.core.io.transport.modbus

my problem:

  • created a Modbus Serial Slave thing → it is working and online
  • created a Modbus Data Poller thing → I don’t know it is working. Here is loggin entry for one poll:
    022-10-11 23:45:12.513 [TRACE] [ternal.ModbusManagerImpl.PollMonitor] - POLL MONITOR: scheduled poll task. FC: READ_MULTIPLE_REGISTERS, start 20480, length 54, done: false, canceled: false, delay: -2308872. Full task BasicPollTask [getEndpoint=ModbusSerialSlaveEndpoint [getPortName()=/dev/ttyUSB0], request=ModbusReadRequestBlueprint [slaveId=10, functionCode=READ_MULTIPLE_REGISTERS, start=20480, length=54, maxTries=3], getResultCallback()=org.openhab.binding.modbus.handler.ModbusPollerThingHandler$ReadCallbackDelegator@410ff5, getFailureCallback()=org.openhab.binding.modbus.handler.ModbusPollerThingHandler$ReadCallbackDelegator@410ff5]
