With Web diagnostics, the CP provides you with the option of calling up the most
important settings of a connected station and the status of their network
connections and communication partners from an HTTP client on a PG/PC. You
can also query the diagnostic buffer entries of the modules of the rack in which the
CP is located.

Using Web diagnostics, you can only read the data of the connected station.

Check the following settings that are necessary for access to the diagnostic data:

S To load diagnostic data, Java Script must be enabled in the Internet browser.
S The browser must support frames.
S Cookies must be accepted.
S The browser should be set so that it downloads the current data from the server

automatically each time it accesses a page.
