In Lean Web Automation, the data from actuators and sensors of automation devices, i.e. the process data, is made available on a web platform. This process data transfer is realized by a Java-based application model. Here, the web clients and the web browsers, have an interface to the process data, which is managed by the LWA server, a proxy server. In this distributed concept, the LWA clients access the LWA servers over the network and can link the process data to other web pages.
