1.2
Communications services
The CP is intended for use in an industrial environment. The following applications are
supported by the CP:
Telecontrol communication
The following applications are possible if telecontrol communication is enabled in the
configuration of the CP.
●Communication with a control center
Remote S7-1200 stations communicate via the mobile wireless network and the Internet
with a telecontrol server in the master station. The telecontrol server communicates with a
higher-level control system using the integrated OPC server function.
●Event-driven sending of messages using SMS or e-mail
Via the mobile wireless network, the CP sends SMS messages to mobile phones or e-
mails to PCs with an Internet connection.
Both types of messages are configured in telecontrol communication in STEP 7. The use
of program blocks is not necessary.
For information on the configuration, refer to sections E-mail configuration (Page 75) and
Messages (Page 86).
●Inter-station communication between S7-1200 stations via the telecontrol server
In this application, the CP establishes a connection to the telecontrol server via the
mobile wireless network. The telecontrol server forwards the messages to the destination
station.
For this communications service, the CP and TCSB use their own protocol on OSI layer 7
that among other things supports certain security functions, see section Other services and
properties (Page 14).
Direct communication via Open User Communication (OUC)
The program blocks of Open User Communication provide the CP with the following
communication options:
●Communication between S7-1200 stations via the mobile wireless network
For this, the CP must be assigned a fixed IP address, see section Other services and
properties (Page 14).
●SMS and e-mail messages via the mobile wireless network
–Sending and receiving SMS messages on mobile phones or S7 stations
–Sending e-mails to PCs with an Internet connection
In contrast to the two corresponding services of telecontrol communication (see above),
to transfer SMS messages/e-mails via OUC, program blocks need to be used, see
section Program blocks for OUC (Page 91).
You will find examples of applications in the section Configuration examples (Page 21).

Data point configuration
Due to the data point configuration in STEP 7, programming program blocks in order to
transfer the process data is unnecessary. The individual data points are processed one-
to-one in the control system.
●
IP configuration
The CP is assigned a dynamic or a fixed IP address by the mobile wireless network
provider:
–Dynamic IP address
When using telecontrol communication, the mobile wireless network provider generally
assigns the CP a dynamic IP address. You set this in STEP 7 in the parameter group
"Ethernet interface > Ethernet addresses".
–Fixed IP address
To use S7 communication or to receive data via Open User Communication, the CPU
must be reachable via a fixed IP address. In this case, enter the fixed IP address
assigned by the mobile wireless network provider in the same parameter group.

●
Time-of-day synchronization
–When telecontrol communication is enabled, the CP obtains its local time of day as
UTC time from the partner (TCSB). The time of day can be read from the CPU. The
mechanisms are described in the STEP 7 information system.
For information on the format of the time stamp, refer to the section Datapoint types
(Page 48).
If telecontrol communication is disabled, the time of day can be obtained from an NTP
server.
–If the security functions are enabled, the secure method NTP (secure) can be used.
For more information, refer to the section Time-of-day synchronization (Page 64).
●
Access to the Web server of the CPU
With the aid of the Web server of the CPU, you can read out module data from the
station.
●
Data buffering: Storage of event data
If a connection fails, the CP can buffer the data of events of different classes and transfer
them bundled to the telecontrol server.
●
Data transfer is on request or triggered
The telecontrol communication with TCSB is triggered in two ways:
–After a request by TCSB or an OPC client connected to TCSB
–Triggered by various selectable criteria
Logging status data and its transfer to the telecontrol server
For example:
–Data volumes transferred
–ID of the wireless cell in the area of the station
–GSM signal strength
–Communication status
etc.
●
Analog value processing
Analog values can be preprocessed on the CP according to various methods.
●

Note
Plants with security requirements - recommendation
Use the following option:
•
If you have systems with high security requirements, use the secure protocols
NTP (secure) and HTTPS.
•
If you connect to public networks, you should use the firewall. Think about the services
you want to allow access to the station via public networks. By using the "bandwidth
limitation" of the firewall, you can restrict the possibility of flooding and DoS attacks.
Industrial Ethernet Security - Security functions of the CP
The following Security functions can be used independently of telecontrol communication.
With Industrial Ethernet Security, individual devices, automation cells or network segments
of an IP-based network can be protected. The data transfer via the CP can be protected from
the following attacks by a combination of different security measures:

Requirements for operation
Hardware requirements
Apart from the CP in the remote S7-1200, the following hardware is also required:
●A CPU with firmware version as of V4.1
●An external antenna for the CP
Use only antennas from the accessories program for the CP, refer to the appendix
Antenna (Page 125).
●For telecontrol communication, a PC with an Internet connection is required for the
telecontrol server in the master station.
●If you intend to use TeleService via mobile wireless, a TeleService gateway with Internet
access is required for configurations without a telecontrol server. This is a PC on which
the "TS Gateway" software is installed, see appendix TS Gateway (Page 125).

Configuration software
To configure the module, the following configuration tool is required:
STEP 7 Basic V13 + SP1
Program blocks for Open User Communication and S7 communication
For Open User Communication and S7 communication, program blocks are required, see
section Communications services (Page 13).
Software for telecontrol communication and TeleService
The CP is configured in "Telecontrol" mode.
●For the telecontrol communication
The telecontrol server requires the "TCSB" software in the master station.
●For TeleService
For TeleService a switching station is required between the CP and the engineering
station (with STEP 7 in the version specified above).
This is either the telecontrol server or a TeleService gateway:
–When using telecontrol communication, the telecontrol server is the switching station.
–To use TeleService without a telecontrol server, the "TS Gateway" software is required
for the TeleService gateway.
The software and the manual describing it are on the DVD that ships with the CP.
For the documentation of the application, see /4/ (Page 130) or /3/ (Page 130) in the
References.
Requirements for using mobile wireless services
●A contract with a suitable mobile wireless network provider
The contract must allow the transfer of data.
IP address:
–For communication with the telecontrol server, a private (fixed) or public (dynamic) IP
address assigned by the mobile wireless network provider can be used.
–For direct communication between S7 stations (S7 communication and Open User
Communication via T blocks) the mobile wireless network provider must assign a fixed
IP address to the CP and forward the frames to the destination nodes.
●The SIM card and PIN belonging to the mobile wireless contract
The SIM card is inserted in the CP.
With mobile wireless contracts in which the network provider does not assign a PIN, no
PIN is necessary for the configuration of the CP.
●Local availability of a mobile wireless network in the range of the station.
