PHOENIX CONTACT 108580_en_02
1.6.1 Product changes
Modifications to hardware and firmware of the device are not permitted.
Incorrect operation or modifications to the device can endanger your safety or damage the
device. If the device is defective, please contact Phoenix Contact.
Do not carry out any
repairs
Repairs may not be carried out on the RFC 4072S.
Do not open the housing/
security seal
It is strictly prohibited to open the RFC 4072S housing. In order to prevent manipulation of
the device supplied and to detect unauthorized opening of the device, a security seal is
applied to the device (see Figure 2-10 on page 40 ). This security seal is damaged in the
event of unauthorized opening. In this case, the correct operation of the device can no longer
be ensured.
1.6.2 Unauthorized network access
NOTE: Risk of unauthorized network access
Connecting devices to a network via Ethernet always entails the risk of unauthorized
access to the network.
Therefore, please check your application for an option for disabling active communication
channels (e.g., DCP, etc.) or setting passwords to prevent third parties from accessing the
controller without authorization and modifying the system.
Due to its communication interfaces, the controller should not be used in safety-critical
applications unless additional security appliances are used.
Please take additional protective measures in accordance with the IT security require-
ments and the standards applicable to your application (e.g., virtual networks (VPN) for
remote maintenance access, firewalls, etc.) for protection against unauthorized network
access.
On first request, you shall release Phoenix Contact and the companies associated with
Phoenix Contact GmbH & Co. KG, Flachsmarktstraße 8, 32825 Blomberg (hereinafter
collectively referred to as “Phoenix Contact”) in accordance with §§ 15 ff AktG or German
Stock Corporation Act from all third-party claims that are made due to improper use.
For the protection of networks for remote maintenance via VPN, Phoenix Contact offers
the mGuard product range of security appliances, a description of which you will find in
the latest Phoenix Contact catalog ( phoenixcontact.net/products ).
Additional measures for protection against unauthorized network access can be found in
the AH EN INDUSTRIAL SECURITY application note. The application note can be down-
loaded at phoenixcontact.net/product/1051328 .
