In order to communicate with an endpoint you need a gateway license for the Unified-E App Manager which is running on the gateway. Register here. For developers the license is for free. All required software can be downloaded here.
Communication never takes place directly with the endpoint but always indirectly via a gateway.
You will create your operator app within the Unified-E App Designer. Get the latest version of the Unified-E App Designer and install it on your developer PC.
Create a New Project
A view configuration might look like this:
Test your application in the simulator either by simulated values or by connecting directly to the endpoint.
Directly Connecting to Endpoints:
This is only possible if you have direct access to the endpoint. This test can be started by commanding the menu 'Run->Run'.
Start this test by commanding the menu 'Run-> Run Simulator.'
You can simulate datapoint values in the datapoint table by entering values in the "Simulated values" column.
Generate an “App Package“
The App package contains both the presentation data with its bound datapoints and the endpoint adapters. Creating the App package is required to get the App installed on the Unified-E App Manager.
The App package is now ready for being installed on the Unified-E App Manager.
Get the latest version of the Unified-E App Manager and install it on your gateway.
Requirements for the gateway computer:
The endpoints must be accessible with the endpoint adapters from the gatway (e. g. via local network). In case you want to use your operator app via internet the gateway also has to be connected to the Internet.
Install the App Package
The gateway is now ready for user registration.
Get Unified-E App from Store
Download the Unified-E app on the user's smartphone.The following systems are currently being supported:
User Registration Process
Now the user is ready to start the operator app and access the machine or plant.
