How it works
Section titled “How it works”The server loads a project, polls PLCs through drivers, keeps history and alarms, and runs server scripts. Clients connect to the server: desktop programs on port 5100 (gRPC) and browsers on port 5101 (gRPC-Web). The server applies project edits while running.
