Topology display The option allows the display of topology information for the
networked PROFINET IO interfaces of the CP in the Web
server.
To collect and store the topology information, additional memory
is taken up on the CP. With complex project configurations
making high demands on the memory resources, it may
therefore be advisable to activate the option only temporarily for
service purposes.
With a large number of devices in a PROFINET IO system, the
size of the configuration data can exceed the maximum
permitted value. In this case, you need to deactivate the
topology display.
Download firmware via Web By enabling the option, the function for downloading the
firmware of the CP from the download center is enabled in the
Web server.
This option is not restricted by the user administration if security
is disabled. It is therefore recommended that the option is
enabled only when required.
Reload of language files for the
diagnostics displays via Web
Diagnostics displays of the CPs are shown in plain language in
the Web diagnostics buffer. These displays are language-
specific.
If you enable the option, the function for reloading missing
language files from the download center is enabled in the Web
server.
