4.6 Calling a TeleService connection
Requirement for switching the connection
The request for connection establishment is triggered by the engineering station. To switch
the connection to the remote station, a telecontrol server or a TeleService gateway is
required. See also section Requirements for operation (Page 12).
Procedure for connection establishment for TeleService

attempt to connect via Ethernet. Reason: In STEP 7, the last connection path used to
download the project data is stored.
TeleService only from one STEP 7 project
You can only operate TeleService on an engineering Station from within a single STEP 7
project. TeleService from more than one STEP 7 project at any one time is not possible.
Terminating a TeleService connection
On completion of the TeleService session, terminate the TeleService connection again using
the "Go offline" button. The connection is terminated after approximately 5 minutes.
Loading only in offline mode
