Security
informa-
tion
Siemens provides products and solutions with Industrial Security functions that support
the secure operation of plants, systems, machines and networks.
In order to secure plants, systems, machines and networks against cyber threats it is
necessary to implement (and to maintain continuously) a holistic, state-of-the-art Industrial
Security concept. With this in mind, Siemens’ products and solutions are only part of such
a concept.
It is the client’s responsibility to prevent unauthorized access to his plants, systems,
machines and networks. Systems, machines and components should only be connected
with the company’s network or the Internet, when and insofar as this is required and the
appropriate protective measures (for example, use of firewalls and network segmentation)
have been taken.
In addition, the recommendations by Siemens regarding the respective protective
measures have to be observed. For more information on Industrial Security, visit
http://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them even
more secure. Siemens explicitly recommends to carry out updates as soon as the
respective updates are available and always only to use the current product versions. Use
of product versions that are no longer supported, and failure to apply latest updates may
increase customer’s exposure to cyber threats.
In order to always be informed about product updates, subscribe to the Siemens Industrial
Security RSS Feed at http://www.siemens.com/industrialsecurity.

Note
The connection between the engineering station and the GPRS network can also
be established via a TeleService gateway.
The TeleService gateway only serves the “TeleService” function via the mobile
network. With the TeleService gateway, no connections to remote stations can
be monitored and no process data can be transferred (see \5\).
The “TS Gateway” software is included in the scope of delivery of the CP 1242-7
GPRS V2.
Note
In this application example, central station and engineering station have been
integrated into one device.
Remote Station
“Remote Station” refers to a spatially removed remote station with a SIMATIC S7-
1200 CPU and a CP 12427 GPRS V2.
Central station
“Central station” refers to a central control unit (PC, IPC or comparable device) with
internet connection, onto which the TCSB V3 software is installed.
Engineering Station
Engineering Station (ES) refers to a programming device, notebook or a
comparable device with software component STEP 7 V13 SP1 and an existing
internet connection.
Advantages
The solution offers you the following advantages:
TCSB V3 enables economic data communication between remote stations and
the central station.
World-wide access to the remote station is possible via the internet.
The application example can also be used for the CP 1243-7 LTE.

Configuration of a S7-1200 station with CP 1242-7 V2 for communication with
the central station via mobile communications network and the internet.
Configuration of a S7-1200 station with CP 1242-7 V2 for remote maintenance
(TeleService) of the remote station that is operated by a service operator.
How the remote station can be maintained by a service operator.
3.1 Connection buildup between remote station and
central station via TCSB V3
The following diagram shows the complete system with all parameters required for
communication between the remote station and the central station. In this
application example, the connection is established via TCSB V3.
Figure 3-1
1. PIN number of the SIM card that is installed into the CP 1242-7 V2.
The CP 1242-7 V2 logs in automatically at the GSM network of the provider,
given that the PIN number of the installed SIM card has been recognized as
valid.
2. APN
The CP 1242-7 V2 logs in at the GPRS access point of the mobile service
provider using the APN address, APN user name and APN user password. An
IP address from the address area of the provider is assigned to the CP 1242-7
V2. It is now accessible via internet and can send IP-based requests to other
participants on the internet.

Siemens AG 2016 All rights reserved
Note
The APN user name and the APN user password are provider-dependent
3. Fixed IP address
The CP 1242-7 V2 sends a connection request to the central station. The static
IP address of the internet connection for accessing the central station is
required.
4. 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.
5. Project number, station number and TeleControl password
TCSB V3 checks the connections request of the CP 1242-7 V2, using the data
(project number and station number) stored in the configuration.
To authenticate the remote station, an additional password is requested.
If the connection request is evaluated successfully the TCSB V3 updates the
internal routing table entry related to this remote station and the corresponding
current IP address of the CP 1242-7 V2. A connection for the transmission of
TCP/IP packages is established between the CP 1242-7 V2 of the remote
station and the central 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 3-1.
Figure 3-2
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.

4. TeleService user name and password
For protection against an unauthorized access to the CP 1242-7 V2, the
TeleService user name and password are requested during the start-up of the
TeleService session.
If the teleservice connection request is validated, diagnostic and program data
can then be transferred between the remote station and the engineering
station. The process value communication is not affected by this.
