Web Diagnostics; Requirements - Siemens S7-300 Configuration Manual

Web diagnostics

With Web diagnostics, the CP provides you with the option of querying and displaying the
most important settings of a connected station. You can also call up the statuses of your
network connections and communications partners from a HTTP client on a PG/PC. It is also
possible to query the diagnostics buffer entries of the modules of the rack in which the CP is
located.
Note
Depending on the CP type
The diagnostics pages or parameters described below are not all available for every CP
type.
Depending on the CP type, you will find, for example, information on the device as
PROFINET IO controller or PROFINET IO device in the navigation panel under "PROFINET
IO". If the CP supports various PROFINET IO modes, this depends on the specific
configuration of the device.
Note
Module replacement - display of the Web pages
When replacing modules, they can be replaced by newer modules without adapting the
configuration data to the new module type.
In such situations, the newly used CP shows the Web pages that match the range of
functions of the replaced module in Web diagnostics.
The CP 443-1 Advanced (GX20), for example, does not support the firmware download
functionality via Web diagnostics. If you replace this CP with a CP 443-1 Advanced (GX30),
the update center will not be displayed although the new module type would support this
function. The full range of functions in Web diagnostics is only available after updating the
configuration data to the new CP type.
