As shown in the next figure, the configuration parameters related to the secure Web server are
located in the "General" tap at a CMU module (Hardware tree only). To secure the RTU500 series
Web server with a self-signed certificate follows these steps:
1 Select the checkbox "Secure HTTPS Web server".
2 Select the option "Self-created and self-signed certificate" in the drop-down menu "Web-server
authentication" (shall be pre-selected).

For the usage of an external HTTPS certificate, the certificate store has to be configured at first.
That means an entry has to be added to the certificate store representing the certificate used for
the Web server authentication. The certificate store configuration opens by pressing the button
"Configuration" shown in the figure above (near the text "Certificate Storage"). When selected a
dialog appears with several entries for certificates. Each entry represents a certificate that shall be
transferred to the CMU. To add a certificate, select the check box at the entry number and give the
entry a descriptive name. An example of the certificate store configuration is shown in the figure
below.
