Operation principle

For accessing the IED using a web browser, WEBSERVER works as an interface function to accept
requests and send data. The actual webpages to be displayed are defined by HTML files stored in
the IED. WEBSERVER interacts with the authority system in the IED to validate user permissions.
Access to the IED from a web browser can be disabled by setting Operation to "Off".
It is possible to change IED parameters and settings through Web HMI. This feature can be disabled
by setting WriteMode to "Writing disabled".
From a security point of view, it is desirable to terminate a browser session if the user has been idle
for some duration. This duration can be set by SessionTimeout.
