Obviously the new behaviour is not good for every use case. It’s a shame that I commented some of these points to the PR when it had several commits but apparently those are now lost after the commits were squashed into single commit. Perhaps most importantly, the binding still establishes as many connections as there are slaves defined in openhab.cfg (in the beginning when binding is being configured).Honeywell Modbus TCP implementation guide explicitly recommends not to open & close tcp connection on every modbus transaction (see p.connections were not closed with other connections (serial ports for example).various other fixes were done to close connections, for example ModbusTCPSlave did not close the socket on resetConnection, or ModbusXTransport did not close the underlying socket/serial port etc., connections were not closed on update – I concluded that these bugs might have been the reason for the original statement.there is reconnecting parameter already in jamod serving that purpose (but when looking at it, openhab binding has hardcoded default of reconnecting=false ). I think I have deleted those with the following logic Setting the Login key to false will allow this device to connect successfully.Darn, you are correct! Obviously that was a mistake - sorry for that! If they dont log in then you will see the following in the Modbus Server log… Not very many MODBUS clients implement a login. If any configuration needs to be changed it will probably be the Login setting. If a request is not made within this amount of time then the JNIOR will close the connection. The Timeout setting is the number of milliseconds to wait for a MODBUS client to poll the server. Most likely this will NOT need to be changed. Lastly, you can change a few configuration parameters for the MODBUS server under the registry tab. To verify that the MODBUS server is running we can list the listening network sockets using the netstat command. You will need to reboot the JNIOR at this point to get the MODBUS Server to start. This will tell the JNIOR to run the application when the JNIOR boots up. You will see a list of applications that are loaded on the JNIOR. Half way down the left side click on Applications. To activate it go to the DCP, click on the Configuration tab. It must be activated by the end user before the the MODBUS connection can be successful. It does not run by default when the JNIOR is shipped. The MODBUS server running on the JNIOR is a separate application from the Operating System.
