The HMI Software at a Glance

The Unified-E software consists of three seamlessly integrated applications for creating and using HMI visualizations.
The graphical HMI editor is used to design user interfaces. Optionally, the HMI Server can be used for central data management and communication. The finalized visualization is run on the operator device via the HMI Client.


All applications can be downloaded from the Download section – pricing information is available on the Licenses and Pricing page.
Below is an overview of the three Unified-E applications:

HMI Editor: Unified-E App Designer

The Unified-E App Designer is an intuitive HMI design tool for creating operator interfaces and views.
In addition to configuring views, the HMI Editor also allows you to set up cross-functional features such as alarm messages with email or smartphone notifications, recipe management, and trigger events.

For more information, visit the Unified‑E App Designer page.

HMI Server: Unified-E App Manager (optional)

The optional Unified-E App Manager acts as an HMI server with centralized data management.
The server functionality is used when, for example, a smartphone needs to communicate with the system via the internet, or when multiple operator devices access a plant simultaneously. Since the HMI server functions as a gateway from the clients' perspective, this is also referred to as gateway communication.

For more information, visit the Unified‑E App Manager page.

HMI Client: Unified-E Client

The Unified-E Client is installed as the HMI client on the respective operator device. The visualization created in the App Designer is registered there and used for operating and monitoring machines and systems.

How Applications Interact

The following diagram illustrates how the Unified-E applications interact and what tasks they perform. The Unified-E App Manager is only necessary if a server solution is preferred.

Communication Types

In direct communication, operator devices and PLC controllers or endpoints are located in the same network. Visualization data is exchanged directly between the operator device and the controller, without any additional software or gateways. The HMI operation app is created using the "Unified-E App Designer" and installed on the device using the "Unified-E Client" application.

In gateway communication, a Windows PC with the "Unified-E App Manager" handles both server and gateway functionality. Data such as recipes or alarm messages is stored centrally, and requests from operator devices are securely received by the App Manager and forwarded to the endpoints.

The applications already include integrated communication drivers (endpoint adapters) for the most common protocols used to connect endpoints and PLCs.
