Functions
8.3 Web server
• The IP parameters of the IO device are assigned online (static IP parameters).
• The IP parameters are created and assigned by the IO controller (dynamic IP parameters).
Note the information in chapter IP parameters (Page 61).
Note
Keeping IP parameters of the web server
If the web server should always be accessible via the same IP address, static IP parameters are
recommended.
Result
You have set the IP parameters and can establish a connection via the web.
8.3.5
Certificates
To access the web server via a secure https connection, the web browser requires a valid
certificate from the web server. For certain changes (e.g. IP address or major changes in date and
time) in the 3RW5 communication module or in the 3RW55 or 3RW55 Failsafe soft starter, the
web server generates a CA certificate with a validity of 30 years for this purpose. If the web
browser does not yet have a valid certificate, or an existing certificate is invalid or has expired,
install a current certificate.
Requirements
The current clock time and date are stored in the 3RW55 or 3RW55 Failsafe soft starter (manually
or with NTP (Page 90)).
Procedure
1. Click the " Download certificate" button on the "Home" page (Page 100).
2. Open and install the certificate.
8.3.6
Control via the web server
