A good HMI must be simple, and achieving this simplicity begins with the engineering process. Through the integration of TwinCAT HMI in Visual Studio®, the graphical What-You-See-Is-What-You-Get (WYSIWYG) editor enables you to use simple controls from a toolbox, arrange them on the interface and link them to real-time variables. In addition, it is possible to assemble and parameterize user controls from the variety of simple controls, making the HMI design kit easy to expand. Ready-made HTML5 templates – like the kind that normally require design specialists – can be integrated with little effort in order to generate complex, yet ergonomic pages. Depending on experience and the application type, the HMI logic can be implemented either on the client side in JavaScript or as a server extension that offers the possibility to create extensions in high-level languages, achieving maximum intellectual property (IP) protection. The HMI automatically adapts itself depending on the respective resolution and orientation of the display hardware; for example, a page can be used for various display sizes, aspect ratios and orientations. Since the browsers are available on different hardware platforms and operating systems, TwinCAT HMI can be executed on all processor platforms without recompiling or adaptation.
