Teleservice Connection Between Remote Station And Engineering Station - Siemens SIMATIC S7-1200 CP 1242-7 V2 Application Example

3 Function principle

3.2 Teleservice connection between remote station and engineering station

3.2 Teleservice connection between remote station and
engineering station
As engineering station and remote station always communicate via the central
station, the central and the remote station need to be connected via the TCSB V3
in this application example. The TeleService connection for loading project or
program data or querying diagnostic data is directly integrated in the main
connection.
The graphic below shows the complete system with all parameters required for a
teleservice communication between remote station and engineering station in
addition to the parameters from
Figure 3-2
Engineering Station
TCSB
Remote Station
1. IP address of TCSB V3
The engineering station sends a connection request to the central station. For
this, the IP address of the TCSB V3 is needed, via which the TeleService
connection between engineering station and remote station is run.
2. Port
As soon as the connection request has been received by the router of the local
IT network of the central station, it will be forwarded to the central station with
the relevant port number.
3. Server password
The TCSB V3 checks the connection request of the engineering station. This
password is used to authenticate the engineering station in the TCSB.
If this remote station is entered in the TCSB V3 and online, the teleservice
request from the engineering station to the remote station is forwarded on the
basis of the existing TCP/IP connection.
