Central, cross-plant user management


SIMATIC Logon offers a number of security mechanisms on both the administrator and user sides. Users are uniquely identified in the usual way by means of a user ID, a user name and a password. Functions like password aging, automatic log-off after a predefined time and blocking the password after entering it wrongly several times guarantee the highest levels of operating security. In addition administrators can set up new users online on a cross-plant and cross-application basis as well as lock these users.


  • Central, cross-plant user management, integrated in Windows User Management

  • High levels of security due to measures on both the administrator and user sides

  • Configurable login procedures (Keyboard input, chipcard)

  • Can be used in different configurations (single-user, client/server systems up to highly available solutions)

Design and functions

User management with SIMATIC Logon integrates itself in the safety system and user management of Windows and in this way meets the FDA requirements.

A configuration tool allows user specific settings:

  • Language (german, english, french)

  • Environment : Domain and workgroup

  • Login device: Keyboard / Chipcard Reader/other devices

Thus users can login in their own language via keyboard or with a chipcard on which name, domain and password are encrypted.

In the SIMATIC WinCC environment, you can use Logon on a wide variety of different structures such as single user stations or client/server configurations. With SIMATIC Logon, the high availability is provided by primary/ secondary domain controllers and the local Windows User Management system.

  • A client connected to the user administration needs an additional Remote Access License

  • For WinCC RT Professional SIMATIC Logon is in the scope of delivery, the clients need no additional licensing.
