1.4 Access to the Web server
The integrated Web server of the RTU500 series is accessed by a Web browser, using the IP ad-
dress of one of the Ethernet Interfaces of the RTU Communication Unit. The figure below shows an
example with the Microsoft Internet Explorer.

The access to the RTU500 series Web server is enabled by default, but it is possible to disable the
access for each Ethernet interface in the configuration tool RTUtil500 [2]. See chapter "RTUtil500
configuration" for information how to disable the RTU500 series Web server.
Besides the secure standard HTTPS access, the RTU500 series Web server supports also HTTP.
For more information about the secure access see chapter 7-1. This chapter describes the
configuration and the certificate handling required for the secure HTTPS access.
After a successful connection, the RTU500 series Web server requests a user name and password
for log-in. An example for the log-in dialog presented by the Web browser is shown in the figure
below. Information about the default user names and passwords can be found in chapter "User
Accounts / Passwords".
