User pages
In the "User pages" area of the Web server you can upload HTML pages you have created
yourself for reading out data of the target system.
Figure 3-69
You create the pages with an HTML editor of your choice from which you generate data
blocks (Web control DB and Fragment DBs) in STEP 7 and download them to the CPU. The
"WWW" instruction synchronizes the user program with the Web server on the CPU and
initializes the Web server. With the first call of the "WWW" instruction, the link to the user
page is displayed on the web page of the CPU. A click on the link opens the user page in a
new window.
Note
Write access to user pages allows the process parameters and, thus, the operation of the
CPU to be influenced.
To prevent external manipulation, always assign a password for users with write access to
user pages in the user management. You will find information on user management in
section Configuring the Web server (Page 19) under "Amending user management".
