After completing the working session it is recommended to log-off from the RTU500 series Web
server and to close the used Web browser. This prevents the usage of supplied user names and
passwords by unauthorized persons. The log-off is done by selecting the link "Logout" as shown in
the figure below. The appearing dialog must be confirmed with Ok to execute the log-off.

Additional to the manual log-off, the user will be logged off by the RTU500 series after a configurable
time of inactivity. The timeout for automatic logout after user inactivity could be disabled and is
configurable between 1 minute and 24 hours. In RTUtil500 the inactivity timeout parameter is placed
in the "Parameter" tap at an RTU (Network or Hardware tree). The figure below shows the according
RTUtil500 parameter user interface.
