OPC UA certificates and keys

To communicate securely, OPC UA applications must have appropriate public certificates and corresponding private keys.
You can use the same certification for projects that have OPC UA server and OPC UA client objects. See OPC UA communications security.
You can set the trusted certificates of other OPC UA applications at design time or runtime. Set certificates at design time for:
  • The available certificates
  • A functionality that is not available at runtime
IMPORTANT: At design time, when a known application changes its certificate:
  • Repeat the configuration.
  • Republish the
    FTOptixApplication
    .
