Siemens Web-Server OZW772... V5.2 CE1N5701en
Building Technologies 2014-10-15
Web operation via portal takes place through an HTTPS encrypted connection
(Port 443) via TCP/IP. The required certificate is accredited.
Web operation without portal takes place through an HTTPS encrypted connec-
tion (Port 443) via TCP/IP. The required certificate is not accredited. The self
signed certificate by Siemens has saved on the web server for a period of 20
years. The certificate can be installed in the web browser as needed.
In addition, an HTTP (Port 80) connection is supported. Port 80 is disabled as de-
livered. The access via http is not secured. The user is responsible for enabling
Port 80.
A RNDIS driver on the PC/laptop is required for USB communication. The RNDIS
driver is automatically installed on PC/laptops connected to the Internet (provided
the network administrator enables "online update"). The RNDIS driver is also saved
to the web server under http://<IP address>/drivers/.
Fault messages, consumption data, energy indicator reports, and trend files are
sent in an e-mail via SMTP. The e-mail is encrypted using TLS if supported by the
mail server.
The web server can take its network configuration as client from a DHCP server.
Execution
The web server consists of a housing lower section containing printed circuit
boards with interfaces. The upper housing section covers the printed circuit boards.
The upper housing section contains the LED displays and one operating button.
The connection terminals and additional display and operating elements are locat-
ed under the removable cover for the upper housing section. All display and oper-
ating elements are labeled.
