Basic safety instructions

2.6
IT security
We only provide a warranty if the device is installed and used as described in the
Operating Instructions. The device is equipped with security mechanisms to protect it
against any inadvertent changes to the device settings.
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.
2.7
Device-specific IT security
The device offers a range of specific functions to support protective measures on the
operator's side. These functions can be configured by the user and guarantee greater in-
operation safety if used correctly. An overview of the most important functions is provided
in the following section.
2.7.1
Protecting access via hardware write protection
Write access to the device parameters via the local display or operating tool (e.g. FieldCare,
DeviceCare) can be disabled via a write protection switch (DIP switch on the motherboard).
When hardware write protection is enabled, only read access to the parameters is possible.
2.7.2
Protecting access via a password
A password can be used to protect against write access to the device parameters.
This password locks write access to the device parameters via the local display or another
operating tool (e.g. FieldCare, DeviceCare) and, in terms of functionality, is equivalent to
hardware write protection. If the service interface CDI RJ-45 is used, read access is only
possible if the password is entered.
User-specific access code
Write access to the device parameters via the local display or operating tool (e.g. FieldCare,
DeviceCare) can be protected by the modifiable, user-specific access code (→ 118).
When the device is delivered, the device does not have an access code and is equivalent to
0000
(open).
General notes on the use of passwords
• The access code and network key supplied with the device should be changed during
commissioning.
• Follow the general rules for generating a secure password when defining and managing
the access code or network key.
• The user is responsible for the management and careful handling of the access code and
network key.
• For information on configuring the access code or on what to do if you lose the
password, see the "Write protection via access code" section → 118
2.7.3
Access via fieldbus
Cyclic fieldbus communication (read and write, e.g. measured value transmission) with a
higher-order system is not affected by the restrictions mentioned above.
