The CODESYS Visualization contains display variants (runtime clients) for the representation of graphical visualization images, which were created within the CODESYS Development System, the market-leading IDE according to IEC 61131-3. These variants run as separate products on different platforms: CODESYS HMI is a variant for Windows or Linux systems, but can also be ported to other operating system platforms. CODESYS WebVisu uses HTML5 to display the generated graphical visualization images within web browsers. With CODESYS TargetVisu, the generated images can be loaded directly onto suitable embedded systems that have a built-in or connectable display and used there. Using various communication options, control data can also be visualized on remote devices. Many available graphical operating elements and functions, such as language switching, integration of HTML pages, overlay technology, client animations, responsive design or integration of web applications, enable the simple configuration of intuitive user interfaces.
