Posted 29 Oct 2019 Hello, We have M580 behind NAT router and we want to download programs to M580 with Unity Pro XL over web. We need to do port forwarding to PLC IP address on router. What TCP port Unity Pro uses when downloading programs to M580? Share this post Link to post Share on other sites
Posted 29 Oct 2019 (edited) It depends on which of the ports on the cpu you are connecting to. But normally tcp uses port 502 Edited 29 Oct 2019 by cHud Share this post Link to post Share on other sites
