Project security
Overview
Operation of a project can be protected by the configuration engineer by implementing a
security system.
If operator control objects protected by a password are operated, the HMI device requests
the entry of a password. A logon dialog opens for you to enter the password.

Password:
OK

Press and hold the
+/–

key until the required character appears.
3.
To obtain additional characters, press
INS
and select the character with

You can use the protected control objects after you completed the logon.
The Logon dialog can be set up by the configuration engineer via an individual operator
control object.
In the same way, the configuration engineer can set up an operator control object 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.
Logoff time
A user logoff timeout can be set in the system. If the time between any two user actions, e.g,
entering a value or changing screens, exceeds this logoff time, the user is automatically
logged off. The user must then log on again to continue to operate objects assigned
password protection.
