Ecostruxure Process Expert[2021]: Unable to connect simulator from remote Engineering Client.
This document explains user what needs to be done when User wants to connect to a Simulator running on System Server from Remote Engineering Client.
When User Runs a simulator on Engineering Server Machine, by default the simulator will run with 127.0.0.1 IP address with a port defined like 502. If user wants to connect the Simulator from Remote Engineering client, then he will not be able to connect.
In order to have connections from other PCs to Simulator, User need to change the Simulator IP address from 127.0.0.1 to its own host IP address. Example is shown in the below Screenshot.
Also, ensure that the local windows firewalls are disabled or add firewall rules which should allow the port 502 on both the System server Machine as well as Remote engineering client machine.
