User administration and traceability


The option package SIMATIC Logon serves to create access privileges for projects and libraries in STEP 7. When access protection is activated, a change log can be recorded.


The following are recorded, for example:

  • Activation

  • Deactivation

  • Configuration of access protection and change log

  • Opening and closing of projects and libraries, including loading onto the target system and activities for changing the operating state

The changes can also be accompanied by a reason or other remarks.

SIMATIC Logon can be used to determine who is permitted to use a license (e.g. external personnel) or who can transfer a license and therefore has permission to download it from the server for servicing purposes.

Functions for meeting FDA requirements

With S7-Graph, S7-SCL and S7-HiGraph (from STEP 7 V5.4) in combination with the SIMATIC Logon option package, functions can be implemented that support tracking and tracing as required by the FDA(Food and Drug Administration):

  • Project password
    Access to projects and libraries can be protected by a project password.

  • Change log
    Access protection for projects and libraries can be used to maintain a change log. Online actions such as downloading, operating status changes, or memory reset are then logged. When executing these actions, operators are prompted to enter a comment giving a reason for the action.

SIMATIC Logon is also offered as an option package for the HMI software packages WinCC (up to V6.2) and WinCC flexible to meet requirements of user administration in the sector of operator control and monitoring.
