With Procon-Web, GTI-control has created an HMI solution that is based on web technology for all common browsers and can therefore also be used with smartphones and tablets. Support for responsive design, multi-touch gestures such as swiping, scrolling, zooming and other animations allow the creation of GUIs. The platform-specific server component can be ported to different system environments and operating systems. Customer-specific adaptations and extensions are possible. According to the manufacturer, the modular structure and the client-side implementation of the user interface keep the server hardware requirements low. A variant is also available that runs as an ST library under Codesys.
