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 form one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. These systems, machines and components should only be
connected to the enterprise network or the Internet if and only to the extent necessary and
with appropriate security measures (firewalls and/or network segmentation) in place.
You can find more information on protective measures in the area of industrial security by
visiting: (https://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends performing product updates as soon as they are
available and using only the latest 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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under (https://www.siemens.com/industrialsecurity).

least IP54 (according to EN/IEC 60529, GB/T 4208) in compliance with EN IEC/IEC 60079-7,
GB 3836.8.
WARNING
EXPLOSION HAZARD
Take measures to prevent transient overvoltages of more than 40% of the rated voltage (or
more than 119 V). This is the case if you only operate devices with SELV (safety extra-low
voltage).
WARNING
EXPLOSION HAZARD
Do not use any parts that show evidence of damage.
WARNING
EXPLOSION HAZARD
DO NOT CONNECT OR DISCONNECT EQUIPMENT WHEN A FLAMMABLE OR COMBUSTIBLE
ATMOSPHERE IS PRESENT.

WARNING
EXPLOSION HAZARD
DO NOT OPEN WHEN ENERGIZED.
WARNING
Ambient temperature in the hazardous area
At an ambient temperature of ≥60 °C, use heat-resistant cables designed for an ambient
temperature at least 20 °C higher.
The cable entries used on the enclosure must comply with the IP degree of protection
required by EN IEC / IEC 600079-0, GB 3836.1.
WARNING
Unsuitable cables or connectors
Risk of explosion in hazardous areas
•Only use connectors that meet the requirements of the relevant type of protection.
•If necessary, tighten the connector screw connections, device fastening screws,
grounding screws, etc. according to the specified torques.
•Close unused cable openings for electrical connections.
•Check the cables for a tight fit after installation.
WARNING
Unprotected cable ends
Risk of explosion in hazardous areas through unprotected cable ends.
•Protect unused cable ends according to IEC/EN 60079-14.
WARNING
Lack of equipotential bonding
If there is no equipotential bonding in hazardous areas, there is a risk of explosion due to
equalizing current or ignition sparks.
•Ensure that equipotential bonding is available for the device.
WARNING
Improper installation of shielded cables
There is a risk of explosion due to equalizing currents between the hazardous area and the
non-hazardous area.
•Shielded cables that cross hazardous areas should be grounded at one end only.
•You must lay a potential equalization conductor with grounding at both ends.

Notes on parallel operation with other USB devices
Note
The use of other USB devices (for example a WebCam, bulk memory) on the PG/PC can impair
the performance of the communications processor.
Note
Removing and inserting USB devices can cause functional disruptions on the USB interface. In
extreme cases, c
ommunication via the communications processor may even be aborted
making it necessary to restart the application.
Note
•
First install the software
First install the software before you connect the communications processor to the PG/PC,
see the section Software installation (Page 15).
•
Activated plug and play function
The plug and play function must be activated in the BIOS of your PG/PC.
Permitted number of communications processors in the PG/PC
The driver software supports a maximum of 1 CP 5711 per PG/PC.
Connecting to the PG/PC
Before you connect the communications processor to your PG/PC, note the following
information:
USB cable
To connect the communications processor, use only the supplied USB cable or another USB
cable suitable for industrial use.
USB connection to PG/PC
To achieve the guaranteed configuration limits with all protocols and at all bus transmission
speeds, you should use at least a USB 2.0 high-speed connector.
You should preferably use the USB connectors located at the back of the housing of your
PG/PC. The front USB connectors usually have a lower signal quality.
We recommend that you do not use any additional USB hubs.
