8.12 Project security
8.12.1 Overview
Design of the security system
The configuration engineer can protect the operation of a project by implementing
a security system.
The security system is based on authorizations, user groups and users.
If operating elements protected by a password are operated, the HMI device first requests
that you log on. A logon screen is displayed in which you enter your user name and
password. After logging on, you can operate the operating elements for which you have
the necessary authorizations.
The logon dialog can be set up by the configuration engineer via an individual
operating element.
In the same way, the configuration engineer can set up an operating element to log off. After
logging off, objects assigned password protection can no longer be operated; to do so,
log on again.
Further information on this may be available in your plant documentation.
User groups and authorizations
Project-specific user groups are created by the configuration engineer. The "Administrators"
and "PLC User" groups are included in all projects by default. User groups are assigned
authorizations. Authorization required for an operation is specifically defined for each
individual object and function in the project.
