Configure service TCP ports

Important: As of AVEVA System Platform 2014 R2, there is no need to configure any TCP ports. All Platform Common Services communication is based on the Microsoft WCF shared port 808. This information is retained for existing applications built with a version of AVEVA System Platform prior to the 2014 R2 release that have been assigned custom port numbers.

On a node running an OPC UA server, you need to open two ports, one for the OPC UA server and one for the OPC UA discovery service, if configured. See the following table for more information about OPC UA port configuration.

The ASB Core Services, installed with PCS and started by the Watchdog Service, also use specific ports. The following table lists the default TCP ports assigned to the user-configurable PCS Services and the ports in use for the PCS Core Services.

• The PCS Core Services port numbers should not be used to configure instances of user services.

• The firewall must allow incoming connections to the ports in the following table for their corresponding services to function.

Important: If a Galaxy Repository (GR) has more than one Galaxy, two additional ports must be opened to enable a remote GR to browse to each additional galaxy. For example, two galaxies would require ports 7500, 7501, 7502, and 7503 to be open. Three galaxies would require ports 7500-7505 to be open.
