matb66 Posted May 4, 2020 Report Share Posted May 4, 2020 I have a project with V700s, V430s and V350s. Many of each. There is a cluster of up to 5 HMIs connected to a router in each of a number of control panels. Each HMI has a consecutive IP address and a consecutive port number within its own control panel. The router has port forwarding set up so that to communicate with any of the HMIs behind the router you address it by router IP and port number. This works for V700s, tested Ok. The V700s are set to UnCmDrv1.dll protocol on each port as a slave by default. With the V430s and V350s there will be max 4 HMIs because of the number of sockets. What I'm not sure about with these is that the documentation states alternate functions for the sockets eg. UDP for inter HMI comms on Socket 0 - Port 20000, Modbus on Socket 2 - Port 502. I need all 4 sockets on the V430 to behave like the V700 does... Standard TCP Comms via UnCmDrv1.dll for Remote Access etc. And what ports can or should I set them to? Will they work if they are set to ports 20256 to 20259 consecutively? Quote Link to comment Share on other sites More sharing options...
