Short Description

Accessing a web visualization via the CODESYS Automation Server:

What does this mean?

  • Accessibility of the visualization from anywhere in the world
  • No VPN or additional third-party remote maintenance solutions required
  • Secure encrypted communication between browser, the CODESYS Automation Server, and the controller network
  • Full control over access privileges


Accessing web visualizations via a direct connection to the corresponding PLCs is time-consuming and expensive. It also entails a number of risks, particularly if the PLCs are publicly accessible, e.g. via the Internet, or if the web visualizations are not protected against unauthorized access.

The CODESYS Automation Server now offers you secure and easy access to your visualizations from any location by simply tunneling them from the PLC via the Server.

The Server can only be accessed by authorized users. Additionally, it can be secured by a second factor. Communication is secured by certificate-based TLS encryption - no need for open ports in the firewall. Your Server software is always up to date, which means that your devices and data are optimally protected by strong security measures. So, consider the problem of security solved.
