configuring the network parameters
Subject to errors and modifications:
Entries made by the user on a Web page are first temporarily
stored by the browser and only sent to the server after clicking on
the
Submit or Temporary Storage button through a new TCP
connection.
If for example the browser is closed before the Temporary Storage
button is clicked, the entries are irretrievably lost. This can also
happen if the Web site is changed without sending the entries.
Nearly all the Web sites that can be opened from the navigation
tree offer the possibility of making or changiong entries. Once
you are finished with the entries on such a configuration page,
you must first click on the
Temporary Storage button and only
then change to a new Web site.
Once all the entries and configuration changes have been made,
the new settings must still be activated. Use the
Logout button
located on each configuration page, or use the menu path
Config >> Session Control >> LogOut.
After clicking on the Save button, all the settings are updated
in the Web-IO and the start page is refreshed in Default User
mode. To make additional setting changes, you must log in
again with the necessary access rights.
Login Timeout
If no entry is made in Adminstrator or Operatotmode for more
than 60 minutes, the Web-IO resets itself to Default User rights.
All entries and changes made to this point, even if they were
already sent to the Web-IO, are lost.
