Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
Link: (http://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers’ exposure
to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under
Link: (http://www.siemens.com/industrialsecurity)
Firmware
The firmware is signed and encrypted. This ensures that only firmware created by Siemens
can be downloaded to the device.

more OPC UA clients.
The server function can be enabled or disabled in the configuration.
The OPC UA server supports the following functions:
●Reading and writing tags
●Monitoring tags (MonitoredItems) using Subscriptions
●Hierarchical address browsing
The OPC UA server is implemented based on the "Micro Embedded Device 2017 Server
Profile" of the OPC Foundation. For details, see:

1.3 Configuration examples
Below you will find examples of possible configurations with the "CloudConnect 7" gateway:
Connection of a process station to a cloud broker
In the configuration shown, the gateway reads process data from a process station and
transfer the data to a cloud broker using MQTT.
The process station is a SIMATIC S7-300 in this example. It can also be any other station
from the S7 product family.
A Modbus station, such as the programmable controller of a third-party supplier, can also be
connected.
●When it is connected to a SIMATIC S7, the gateway communicates using an S7
connection.
●When it is connected to a Modbus station, the gateway communicates using
Modbus/TCP.
Figure 1-1 CloudConnect 712 for connecting a station to the cloud
Connection of a process station to OPC UA clients
In the configuration shown, the gateway transfers process data over OPC UA to a central
control room or one or more OPC UA clients.

1.6 Range of functions of the WBM
Web Based Management (WBM)
You configure the gateway using its Web Based Management (WBM). The WBM consists of
Web pages that can be called up in the Web browser of a connected PC. From your PC you
connect to the WBM via HTTPS.
For information on the Web browsers that can be used on the PC, see section Scope of
delivery and requirements (Page 18).
Access to the WBM
To call the WBM, you need to establish a connection between the PC and the gateway via
LAN, see section Establishing a connection to the WBM (Page 42).
Overview of the functions of the WBM
The WBM provides the following functions:
●User management
In the open WBM, you specify the user name and the password for the "Administrator"
role. You can only access the WBM with this administrator information.
●Configuration
Using the WBM, configure the following function areas:
–Basic functions such as the time of day or IP address
–Connection of the process station
–Connection to the higher-level network (cloud, OPC clients)
–Communication functions
●Maintenance and diagnostic functions
–Diagnostics
–Loading and storing the configuration data
–Downloading new firmware versions
Reusing the configuration file
The configuration data you create in the WBM is saved in the gateway.
If you want to back up the data as well, you can also save the configuration data in the WBM
area "Maintenance" on a CLP inserted in the gateway.
If you are using multiple gateways with partially identical configuration data, you can export
the configuration file of a gateway, copy it, and download it to additional gateways where you
can adapt it as needed.
