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.
Depending on your requirements, you decide which applications you need
In direct communication, the operator devices and controllers or endpoints are in the same network. The visualization data is exchanged directly between the operator device and the controller without additional software or gateways. The HMI operator app is created with the "Unified-E App Designer" and installed on the operator device using the "Unified-E App Client" application.
In gateway communication, a Windows computer with the "Unified-E App Manager" takes on both server and gateway functions. Data such as recipes or alarm messages are centrally stored. Requests from the operator devices are encrypted by the Unified-E App Manager and forwarded to the endpoints.
