User-specific access code
Write access to the device parameters via the local display, web browser or operating tool
(e.g. FieldCare, DeviceCare) can be protected by the modifiable, user-specific access code
(→ 159).
When the device is delivered, the device does not have an access code and is equivalent to
0000 (open).
WLAN passphrase: Operation as WLAN access point
A connection between an operating unit (e.g. notebook or tablet) and the device via the
WLAN interface (→ 87), which can be ordered as an optional extra, is protected by
the network key. The WLAN authentication of the network key complies with the
IEEE 802.11 standard.
When the device is delivered, the network key is pre-defined depending on the device. It
can be changed via the WLAN settings submenu in the WLAN passphrase parameter
(→ 153).
Infrastructure mode
A connection between the device and WLAN access point is protected by means of an SSID
and passphrase on the system side. Please contact the relevant system administrator for
access.
General notes on the use of passwords
• The access code and network key supplied with the device should be changed during
commissioning for safety reasons.
• Follow the general rules for generating a secure password when defining and managing
the access code and 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, for example, see "Write protection via access code" → 159.
2.7.3 Access via web server
The integrated web server can be used to operate and configure the device via a web
browser → 79. The connection is established via the service interface (CDI-RJ45) or
the WLAN interface.
The web server is enabled when the device is delivered. The web server can be disabled via
the Web server functionality parameter if necessary (e.g., after commissioning).
The device and status information can be hidden on the login page. This prevents
unauthorized access to the information.
Detailed information on the device parameters:
"Description of device parameters" document .
2.7.4 Access via service interface (CDI-RJ45)
The device can be connected to a network via the service interface (CDI-RJ45). Device-
specific functions guarantee the secure operation of the device in a network.
The use of relevant industrial standards and guidelines that have been defined by national
and international safety committees, such as IEC/ISA62443 or the IEEE, is recommended.
