Version 1.3.0
5.7.2.6 Web Protocols for WBM Access
The HTTP and HTTPS web protocols can be used to access the WBM pages for
the touch panels. HTTPS is preferred because it uses the SSL/TLS protocol. The
SSL/TLS protocol ensures secure communication through encryption and
authentication.
5.7.2.7 TLS Encryption
When an HTTPS connection is established, the Web browser and Webserver
negotiate what TLS version and what cryptographic method are to be used.
The “TLS Configuration” group of the WBM page “Security” can be used to switch
the cryptographic methods allowed for HTTPS and the TLS versions that can be
used.
The settings “Strong” and “Standard” are possible.
If “Strong” is set, the Webserver only allows TLS Version 1.2 and strong
algorithms.
Older software and older operating systems may not support TLS 1.2 and
encryption algorithms.
If “Standard” is set, TLS 1.0, TLS 1.1 and TLS 1.2 are allowed, as well as
cryptographic methods that are no longer considered secure.
BSI Technical Guidelines TR-02102
The rules for the “Strong” setting are based on technical guidelines TR-02102 of
the German Federal Office for Information Security.
You can find the guidelines on the Internet at: https://www.bsi.bund.de >
“Publications” > “Technical Guidelines.”
BSI Guidelines on Migration to TLS 1.2
The German Federal Office for Information Security guidelines on migration to
TLS 1.2 contain “compatibility matrices” that show what software is comparable
with TLS 1.2.
You can find the guidelines on the Internet at: https://www.bsi.bund.de > “Topics”
> “Standards and Criteria” > “Minimum Standards“.

5.7.3.1 Host Name/Domain Name
If the host name is not configured, the panel receives a default name based on
the last three values of the panel's MAC address. The name applies as long as
no host name is configured or no host name is given to the panel by DHCP (to
configure the panel, see section “Commissioning” > “Configuring in the Web-
