The OPC UA Server can be adapted to the requirements of different environments. A number of different security settings are available for this purpose. Changing these settings requires the PLC to be restarted. These values can be set by means of the ⮫ “Dialog: Device Security Settings (OPC UA Server) ” of the PLC.
