Overview

The TwinCAT OPC UA Server enables registration with a Global Discovery Server (GDS). A GDS provides a standardized, OPC UA-based interface for registering OPC UA applications and issuing application certificates as well as the associated revocation list information. A GDS has a connection to a Certificate Authority (CA) for this purpose. Applications are registered and certificates are issued (and updated) using a standardized OPC UA information model.

When accessing the GDS, the TwinCAT OPC UA Server supports the two models Push and Pull.
