Creating proxy points is convenient because is the way of linking the information that the JACE is reading to the supervisor station. To add the proxy points you need to be in your supervisor station, then add a new Niagara Station in your Niagara Network where you have to write the name of the JACE station, the IP address of the JACE and the credentials of the station. Drag the points that you need to your database and ping them to check if there is communication.
If you have any problems adding proxy points, try to deactivate your firewall. Most likely there will be an error with the certificate management, it is easy to fix, go to the Certificate Management in your platform, then go to Allowed Hosts and approve the JACE host (you will identify with the IP address as the name of the host).
