Global Discovery enables a client to find OPC UA Servers within an enterprise using arbitrary network architectures. It is supported by means of a Global Discovery Server (GDS), an OPC UA Server Application that manages a database of OPC UA Applications.

Semi-automatic GDS configuration can be achieved by coupling GDS with subnet discovery. A GDS will typically also provide Certificate Management functions.

Usage Considerations

  • Enables a client to find OPC UA Servers within an enterprise.
  • Clients can search with a capability filter to lookup the appropriate Servers.
  • Combining global discovery with certificate management in a GDS provides for enterprise-wide security configuration.
  • One or more Global Discovery servers can be used to maintain discovery information of installed OPC UA applications.
  • Requires a commercial Global Discovery Server (GDS)
