Establishment of a TeleService connection

Requirement for the engineering station and the STEP 7 project
● The STEP 7 project with the CP is stored on the engineering station.
● The required configuration steps have been performed, see section Configuration of the
TeleService access (Page 87).
Requirement for TeleService via a telecontrol connection: TeleService server
In TeleService via telecontrol, a TeleService server is required as the intermediary between
S7 station and engineering station, see also the section Requirements for operation
(Page 15).
● Telecontrol server
If you use a telecontrol server, the intermediary can be the telecontrol server.
● TeleService gateway
If there is no telecontrol server in your system, a TeleService gateway must exist as the
intermediary.
For documentation of the two systems, refer to References (Page 129).
Remember the following when establishing TeleService connections via mobile wireless.
Note
TeleService only by a TIA Portal instance
You can operate TeleService with a certain S7 station only from a single engineering station
(TIA Portal instance / STEP 7 project). TeleService using several engineering stations at the
same time with a station is not possible.
TeleService with several engineering stations with different S7 stations is possible if the
suitable STEP 7 project exists on every engineering station.
