Function principle
3
This application example shows the following core elements:

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.

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.
The SIM card's PIN number must be enabled.
Note
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.
