    ⇒ Extension can only be implemented by the device manufacturer
    Alternatively: Use of SoftPLC systems in the CODESYS Store, in which CODESYS WebVisu is already implemented or can be optionally licensed.
  • Create an object “WebVisualization” in the Visualization Manager
  • Define
    • the starting object of the visualization
    • the homepage for the web browser
    • some of the required parameters
  • Call up the start page using the IP address/domain name of the controller in the address line of the Internet browser on the display device, e.g. '' or 'http://[DomainName]:[PortAdress]/webvisu.htm'
