Configuring Web server users
You can configure users with various privilege levels for accessing the CPU through the Web
server.
To configure Web server users and their associated privileges, follow these steps:
1. Select the CPU in the Device Configuration view.
2. In the inspector window, select "Web server" from the CPU properties and enable the
Web server (Page 1003).
3. Select "User management" in the Web server properties.
4. Enter user names, access levels, and passwords for the user logins that you want to
provide.
After you download the configuration to the CPU, only authorized users can access Web
server functions for which they have privileges.
