Web operation via Synco IC takes place through an HTTPS encrypted connection
(Port 443) via TCP/IP. The required certificate is accredited.
Web operation without Synco IC takes place through an HTTPS encrypted con-
nection (Port 443) via TCP/IP. The required certificate is not accredited. The self
signed certificate by Siemens is saved on the web server for a period of 20 years
and cannot be changed.

driver is already included in the Windows operating systems for web server as of
version 7.0.

sent in an e-mail via SMTP. The e-mail is encrypted using TLS if supported by the
