4.1.4 Switching via call

You can also switch the outputs via a free telephone call:

1. The device identifies the incoming call.

2. The device checks whether the telephone number is authorized for switching.

3. If the telephone number is authorized, the device closes, opens, or switches one or

more outputs depending on the configuration.

4. The device disconnects the call.

No costs are incurred because the device does not accept the call. Furthermore, the de-

vice disconnects the call, giving the user direct feedback that the call was received.

4.1.5 Communication via app

Download the app free of

charge:

You can also operate the TC MOBILE I/O X200... devices via app. The app transmits the

switching commands. The app then receives feedback from the device via an encrypted

HTTPS data connection.

However, the iOS operating system prevents full SMS communication. Even direct com-

munication between the two cellular network devices is not possible without further

measures (see Seite 25). The data is therefore stored temporarily on a server that is

hosted by Phoenix Contact in Germany. The app calls up the data from this server.

Naturally, alarms via SMS and email are still possible. You thus have the best accessibility

in the field. In order to keep the data volumes as low as possible and conserve battery,

the app does not refresh in the background. When the app is open, however, you can set

cyclical refreshing. This ensures that, for example, analog values are kept up to date,

without a new SMS command being issued each time there is a change.
