# Port numbers

Tabular overview of specified ports, whose configuration can be active or inactive.

In the port overview, services / applications whose configuration is inactive, i.e. whose ports are not currently in use, are grayed out.

The ports for REST API and OPC Server are displayed in the explorer similarly to the Database Server.

During initial setup, the smallest free port within the allowed range is taken as the default value for the REST API.

The "Go to entry..." button opens the configuration for the port selected in the list.
