You configure user roles, associated access levels (privileges), and passwords (Page 604)
in the Web server user management properties of the STEP 7 device configuration of the
CPU.
Logging in
Typically, you do not have to log in to view the data in the standard Web pages. STEP 7
provides an "Everybody" user that, by default, has privileges to view all of the standard Web
pages. To perform certain actions such as changing the operating mode of the controller,
writing values to memory, and updating the CPU firmware you must have the required
privileges. Note that if you have set the protection level of the CPU to "Complete protection
(no access)", then the "Everybody" user cannot access the Web server.
To log in, follow these steps:
1. Enter the user name for the Username field.
2. Enter the user password in the Password field.
