The communication interface, WebConnector, builds a technological bridge between automation and the Internet of Things (IoT) and services. Web applications for new business models can be developed without in-depth knowledge of automation technology with the software component in the Open Core Engineering portfolio. End users and OEMs obtain human-machine-interfaces for mobile and stationary end devices as well as smart services. Process data can also be saved and analyzed in the cloud and can then be used for process optimization or for service purposes.
This communication interface enables a web app to quickly and securely query control data, axis positions, PLC information, diagnosis or processing statuses from machinery and equipment and to then visualize it on an HMI or evaluate it in a database. For example, this allows the development of predictive maintenance and other service concepts.
The platform-independent WebConnector programmed in Java can be used on all end devices on which a Java Runtime Environment (JRE) is installed.
For communication with cloud services, smart devices, and other HMI devices, WebConnector uses the established web standard HTML5 and the WebSocket protocol included therein. The WebConnector alternatively communicates with the automation side using the interface technology Open Core Interface integrated in Rexroth controls and drives, or through the Industry 4.0 Standard OPC UA. Web apps are displayed and operated through a common HTML5-capable web browser. Programmers have HTML5 and CSS available for web application as well as an interface for connecting Node.js applications such as Node RED for instance.
