The Unified-E software applications are available for download below: the HMI Editor, the (optional) HMI Server, the HMI Client, and the user manuals – everything you need for your HMI project.
The communication drivers required to connect to PLC controllers, SQL databases, and other automation systems are already included in the applications. The Software Overview explains how the core applications – HMI Editor, HMI Server, and the HMI Client – work together. For a quick introduction, see the Getting Started guide.
With the HMI editor, you create the specific HMI application for your machine or automation system.
For more information, see Unified‑E App Designer.
3.1.8.0 (08/08/2025)
Fixed bugs when laying out elements within layout panels.
System requirements
License
The HMI editor Unified-E App Designer is generally license-free – no license keys are required. Unified-E only uses runtime licenses per HMI device, which are only needed for actual operation (e.g., in production).
Licensing depends on the use case and is done either in the Unified-E App Manager or the Unified-E Client.
User Manual
You can download the Unified-E App Designer user manual here:
The Unified-E App Manager is an HMI server application that must be installed on the gateway PC. This application is optional and only required when using gateway communication. The main use cases for the HMI server are mobile remote monitoring and plant operation with multiple HMI devices.
For more information, see Unified‑E App Manager.
3.1.4.0 (06/03/2025)
Bug fix when sending alarm emails: The entered SMTP port is now taken into account.
System requirements
License
A free developer license is available for development purposes. For productive operation, gateway licenses are available and can be purchased under Licenses and Pricing.
User Manual
You can download the Unified-E App Manager user manual here:
The Unified-E Client is the runtime application for your HMI devices (Android, iOS & Windows). Install the Unified-E Client on the respective panel, tablet, or smartphone to launch, operate, and monitor an HMI visualization created in the Unified-E App Designer.
For more information, see Unified‑E Client.
This application is to be installed on Windows-based HMI devices to run the HMI visualization (HMI application). The full-screen mode feature allows for stationary HMIs with touchscreen input.
3.1.5.0 (07/14/2025)
Bug fixes for touchscreen input.
System requirements
License
When using gateway communication, no licensing is required on the HMI device – licensing is handled centrally via the Unified-E App Manager.
For direct communication, HMI applications can be used free of charge for 48 hours after registration for development purposes. For continuous operation, a direct license is required and can be purchased under Licenses and Pricing.
User Manual
You can download the Unified-E Client (Windows) user manual here:
This application is to be installed on Android devices such as smartphones, tablets, or HMI panels running Android in order to run the HMI visualization. The installation is done via Google Play.
For Android devices without GMS certification (no Google Play), the APK file can be downloaded here for installation directly on the Android device.
3.1.1.0 (03/18/2025)
Performance improvements when reading datapoints from ControlLogix/Allen-Bradley controllers.
