A web app establishes a connection to the web gateway and communicates with it via WebSockets. These send data from the EASY UI Designer server to the web app and receive data from the web app and send it on to the EASY UI Designer server. As this functionality is visible in the network, it is initially deactivated for security reasons.
The gateway must therefore be activated on the target computer after installation. It must also be activated on the development computer if the web app is to be started there for testing.
