The Everywhere App by zenon – faqs (Part 2)

How do I configure the Everywhere App?

Everywhere App by zenon

After the first start of the Everywhere App, the smartphone user needs to setup the connection to the Everywhere Server. The name or IP address of the computer running the Everywhere Server, the port numbers for HTTP and HTTPS, the name of the zenon project and whether HTTPS is used or not, needs to be specified.

How does the Everywhere App work?

After the connection is set up, the smartphone user can login with the zenon user credentials and choose categories and sub categories (equipment model groups) to choose variables from, to be displayed. Once the variables are selected, the values are displayed in different graphical representations (lists, graphical elements or bar graphs). The smartphone user can change the view to see active alarms.

Is the viewing of the data protected somehow?

In order to display the information, the smartphone user will have to authenticate using credentials of a zenon user created in the zenon Runtime project. Active Directory user authentication, which is available in the zenon Runtime, is not supported in the Everywhere App.

Who can access this data once the Everywhere Server is running?

That depends on a number of factors. First of all, only those smartphone users to which you provide the required configuration and login information have the necessary information to access the Everywhere Server. When using HTTPS on the Everywhere Server with a self-signed certificate, smartphone users also need to have this certificate installed on their smartphone. It further depends on your network configuration and firewall configuration.

Is the Everywhere App safe to use?

The simple answer is yes. The Everywhere App requires authentication and only allows read-only access of the data. However correct configuration of your network, firewalls, intrusion detection systems, DMZ and network monitoring systems can further enhance the security. Of course this does not only apply to the Everywhere Server, but in general is an important part of the planning and operation of any control system.
You could limit access to the Everywhere Server to a single secure WiFi access point in your factory that is behind a firewall, configured to only allow communication to the Everywhere Server, (not to the control network, not to the corporate network, and not to the internet). When you activate the HTTPS option, the network traffic is also protected from prying eyes.

Where to go from here? What if I have concerns, questions or would like to see more functionality?

You can rate the Everywhere App in the iTunes Store or Windows Phone Marketplace and leave feedback for us and other users. For further information, you can of course also always contact your local COPA-DATA support representative.
