Safety information

Siemens offers IT security mechanisms for its automation and drive product port-
folio in order to support the safe operation of the plant/machine. Our products are
also continuously developed further with regard to IT security. We therefore
recommend that you keep yourself informed about updates and upgrades for our
products and always use the latest version of each product. For information on
this topic, refer to: Industry Online Support (http://www.siemens.com/automa-
tion/csi_de_WW). You can register for a product-specific newsletter here.

For the safe operation of a plant/machine, however, it is also necessary to integ-
rate the automation components into an overall IT security concept for the entire
plant/machine which corresponds to state-of-the-art IT technology. You can find
information on this at: Industrial Security (http://www.siemens.com/industrialse-
curity).

Products used from other manufacturers should also be taken into account here.

Network security

In order to protect the entire plant from attacks on network security, correspon-
ding measures must be taken.

Caution

Failures or damage to your overall system

Unauthorized persons can gain entry into your network via the Ethernet ports and
make changes to the SICLOCK TC100 parameterization. This can result in the
time being adjusted. Individual or even all clients to be synchronized can be remo-
ved from the synchronization cycle. This has the potential to cause failures or
damage throughout the plant.

Please adhere to the following safety measures:

− Ensure that your network is protected against unauthorized access by instal-

ling a firewall at all Ethernet ports.

− Change the default password immediately after commissioning.
− Limit the number of people to whom this password is known to the absolute

minimum.

− Change the password regularly.
