WebHMI is connected to a controller, a measured value acquisition system or a smart sensor system via a digital interface. The device can visualize measured values locally or decentrally and transfer data to the cloud in parallel. WebHMI has an integrated, web-based SCADA system with extensive operating and monitoring functions and also combines functions of a (W)LAN router and edge devices. Diagrams can be displayed with any terminal device and browser. The connection is made via the LAN interface or directly wireless via the integrated WLAN. The WWAN interface supports 3G/4G modems.
