System overview and mechanism, display variants

The user interfaces created in CODESYS can be used in different display variants, depending on which ones the controller employed supports.

The display variants

• Visualization (“diagnostic visualization”) integrated in the CODESYS Development System:

  The integrated visualization in the development system is ideal for application tests, for service or diagnostic purposes and for the commissioning of a system. As soon as a connection to the controller has been established, the visualization editor switches over and animates the elements displayed. This variant is part of the free CODESYS Development System and can always be used, irrespective of the controller employed.

• CODESYS Web Visualization:

  This variant means web-based display of the user interface in a standard browser (PCs, tablets, smartphones), enabling remote access, remote monitoring and service and diagnosis of a system via the Internet. A standard web browser communicates by Java Script (optionally with SSL encryption) with the web server in the controller and displays the visualization by means of HTML5. This technology is supported by virtually all browsers and is thus also available on terminal devices with iOS or Android.
