Unified-E consists of several software applications as well as endpoint adapters (communication drivers) for connecting to PLC controllers, SQL databases, and other systems. An overview of how the core applications – HMI Editor, HMI Server, and the client application for HMI devices – work together is provided in the software overview. For a quick introduction, the Getting Started guide is available.

Free for developers – a license is only required for continuous operation per HMI device!
