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.

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.

consists of Web pages stored in the gateway. From a configuration PC you connect to the
WBM of the gateway via HTTPS.
1.3 Configuration examples
Below you will find examples of possible configurations with the "CloudConnect 7" gateway:
Connection of a process stations to a cloud broker
In the configuration shown, the gateway reads process data from one or multiple S7 stations
and transfer the data to a cloud broker or OPC UA client using MQTT.
A Modbus station, such as the programmable controller of a third-party supplier, can also be
connected to a cloud broker for data transmission.
●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.
