7 Web Diagnostics
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.
