Selection guide for WinCC Logon and SIMATIC Logon
Criterion SIMATIC Logon WinCC Logon

SIMATIC BATCH, Route Control, Automation License Manager, SIMATIC Man‐
ager).
Suitable Not suitable
A client/server project with multiple OS clients is used. Suitable Not suitable
A single station is used, or a client/server project with just a few OS clients. The
OS clients are referenced OS clients.
Suitable Suitable
One central administration for users/user groups is required. Suitable Not suitable
No central administration for users/user groups is required. Suitable Suitable
Logon and logoff procedures are to be logged. Suitable Not suitable
SIMATIC Logon is supplied with "Contract License" in SIMATIC PCS 7 V7.1 and above.
This means there are no further licensing costs for SIMATIC Logon within PCS 7. As a result,
we generally recommend that SIMATIC Logon is used, as it provides more benefits than
WinCC Logon and is not associated with any additional costs.
Note
SIMATIC Logon and the User Administrator write different user information to a smart card.
SIMATIC Logon also requires the information as to which logon computer or domain controller
should be used for user authentication.
This is why the Smart card must be specified again with any change from SIMATIC Logon to
WinCC Logon or vice-versa.

is entered.
This means that the user will not be able to monitor or control the process in process mode.
If a properly logged-on user calls an OS functionality which is protected by an authorization,
the User Administrator checks whether the relevant authorizations permit this function to be
