RTU3041C Wake-Up by Mobile Phone

To read current process values, you can wake the RTU from sleep mode between
two communication cycles.
1. To do this, send an SMS with the text "TELESERVICE" to the mobile phone
number of the SIM card inserted in the RTU.
2. The RTU acknowledges receipt of the wake-up SMS at the next time the
mobile wireless interface turns on and connects to the TeleControl server.
Note If you specify an appointment in the wake-up SMS, the RTU will establish a
connection with its communication partner at the exact time you send the SMS.
3. To do this, send "TELESERVICE YYYY-MM-DD hh:mm:ss" to the mobile
phone number of the SIM card inserted in the RTU.

SMS depends on the configuration. The setting can be found in the web interface
of the RTU under "Operating mode", see
Note that enabling the mobile wireless interface increases the power
consumption of the RTU.
