The following example shows the configuration of the OPC UA Server

  • The OPC UA Server is activated by adding the OpcUaServer under Services and setting Enabled to true.
  • The server is configured to not allow unsecured connections by configuring the SecurityPolicies parameter to include Basic256Sha256Sign and Basic256Sha256SignEncrypt.
  • Permission to access the server is given to user User1 via the role OpcUaServerRole which grants the function rights OpcUAServerAccess and OpcUAManageCertificates.
  • Unauthenticated access is permitted by setting GuestAuthentication to false.
