Using the CP as an intermediary for diagnostics data
If you only want to use the CP as an intermediary for diagnostics data of the station, as of
firmware version 3.2 you can network only the gigabit interface and, for example, establish a
VPN tunnel to a PC via this interface. The PROFINET interface does not need to be
networked.
7.3 The CP as Web server
The CP provides you with the functionality of a web server for access by means of a web
browser.
Note
Please note the following special features when using IT functions:
The data exchange for productive communication (S7 connections + SEND/RECEIVE
connections + PROFINET IO) always has a higher priority than data exchange with the Web
browser. This can lead to delays in the HTML process control in the Web browser.
Beans and applets
When shipped, the file system of the CP contains S7 beans and further information.
S7 applets are Java applets specially written for SIMATIC S7 and that are used to allow write
or read access to the S7CPU. You can develop your own S7 applets with the supplied S7
beans and tailor them to your requirements. For information on this, refer to the manual /5/
(Page 118).
