Hello shankar78,

you need to aktivate the systemmessages in the Alarmlogging Editor.

see the manual:
"WinCC V7.4 SP1: Working with WinCC"
"How To Use System Messages"

Hello shankar78,

the users for Simatic Logon are managed inside the Windows OS.
If such a user change its password, it should be logged in
the Window eventlog Security.

Or you should see it in the "SIMATIC Logon Event Log Viewer".

see manual:
"SIMATIC Logon V1.6 Update3"
"How to Track Logons and Logoffs with the SIMATIC Logon Event Log Viewer"

Hello shankar78,

in WinCC are only the following systemmessages for users:
1008000  USERT:Connection to chip card reader paused
1008001  USERT:Incorrect login name/password
1008002  USERT:Incorrect login name/password by chip card
1008003  USERT:Manual Login
1008004  USERT:Login by chipcard
1008005  USERT:Manual Logout
1008006  USERT:Logout by chipcard
1008007  USERT:Automatic Logout by timeout
1008008  USERT: Authorizations of Service users/group effective

If you would like to have a message for changing password,
you need to generate it yourself.
You could create your own Login-Window for Simatic Logon and
use the functions from the "SL_ProgrammingGuide.pdf" in folder
"C:\Users\Public\Documents\Siemens\SIMATICLogon\developmentkit"
in a scripting.
part 5.3.3.9 ChangePassword

And in the same script you can generate a message, when the user
change the password.

see FAQ:
"How do you create user-defined operator input messages in WinCC?"
