Accessing the Web server
To access the Web server, proceed as follows:
1. Connect the display device (PG/PC, HMI, mobile terminal device) with the CPU or a
communication module using a PROFINET interface.
If you are working with WLAN, activate the WLAN on the display device and establish a
connection to the access point (e.g. SCALANCE W788-1RR or SCALANCE W784-1),
which is in turn connected to the CPU.
2. Open the web browser on the display device.
3. Enter the IP address of the interface of the CPU which is connected to the client in the
"Address" field of the web browser in the following format: http://a.b.c.d or https://a.b.c.d
(example input: https://192.168.3.141).
The intro page of the CPU opens.
4. You need to perform the installation of the CA certificate again for each display device
you want to use. A valid CA certificate is available for download from the "Intro" web page
under "Download certificate". You can find instructions for installing the certificate in the
help system of your Web browser and in the FAQ with the entry ID 103528224 at the
Service&Support (https://support.industry.siemens.com/cs/ww/en/view/103528224)
website.
5. Click the NEXT link to go to the Web server pages.

You can find additional information on managing access rights in the "Configuring the
Web server" section of the Web server function manual
