What is Unified-E?

The secure solution to monitor and control your machine via smartphone apps. You create the app for your endpoint like a PLC or controller.

  1. Easy to use: No knowledge of app development and app publishing required.
  2. Secure communication: Communication with the gateway is done via SSL.
  3. Low maintenance: Communication via the Internet is done in a firewall-friendly manner.
  4. Cost-effective, very fast development of operator apps.
  5. Totally free for integrators / developers.
  6. Optimized for automation: Direct endpoint adapters for common PLCs such as Siemens S7, ControlLogix from Allen-Bradley or Beckhoff already exist. Windows applications such as a LabVIEW VI can use the WindowsApplication adapter to provide the app's data.
  7. Support of standard protocols such as Modbus, OPC UA and REST, e. g. for communicating with B&R or WAGO controllers.

How it works!

Communication between smartphone and machine is always done via a gateway which is a Windows computer. The gateway is responsible for SSL, user authentication and it redirects the app requests to the endpoints.

Basically there are three communication modes which are supported from the "Unified-E App Manager" software which is running on the gateway.

Communication modes with the Smartphone

Internet (Direct)
The smartphone directly communicates with the gateway which is connected both to the Internet and to your local (production) network. This mode requires some router and firewall configurations for port forwarding.

Internet (Relay messaging)
The smartphone indirectly communicates with the gateway via a relay messaging service. Advantage: The Gateway does not need to accept any incoming requests, which means that no router or firewall configuration is required.

This mode is used in case the Gateway PC is not connected to the Internet. There are some restrictions: Local push notifications are currently only supported on Android devices and you have to request a license key explicitly.

Online Services

Nearly all communication modes require online services, e. g. to send push notifications. All online services are hosted on the Microsoft Azure cloud platform and ensure a reliable operating.
