●  Telephone wake-up SMS 

The wake-up SMS can be sent from a telephone that has a phone number authorized in 

the STEP 7 project. The telephone must support the CLIP function (transfer of its own call 

number) and the sending of SMS messages. 
The connection establishment with the telecontrol server specified in the SMS is 

triggered. 

Triggering connection establishment in "GPRS direct" mode 

In "GPRS direct" mode, a connection establishment is triggered by the following events: 
●  Event on the local CPU that is evaluated by the program. 
●  Request for TeleService by an engineering station 

The wake-up frame (SMS) from the TeleService gateway does not need to be evaluated 

in the program.

The wake-up SMS 

Right to wake-up by "authorized phone numbers"    

The CP only accepts an SMS if the sending communication partner is authorized based on 

its phone number. These numbers are in configured for the CP in STEP 7 in the "authorized 

phone numbers" list. 

"Authorized phone numbers" in the STEP 7 project 

●  A phone number entered here gives the sender who transfers this phone number the 

right to trigger connection establishment. 

●  If only an asterisk (*) is entered in the list, the CP accepts SMS messages from all 

senders. 

●  An asterisk (*) after a phone number body authorizes connection establishment for all 

nodes connected to the body (extension numbers). 
Example: +49123456* authorizes +49123456101, +49123456102, +49123456207 etc.
