■

SIMATIC Logon is a central user administration function with ac-

cess control based on Windows 2000/XP and Windows Server 

2003 for:
• System components of SIMATIC PCS 7 
• Non-system components linked via an interface 
It can be used to fulfill the validation requirements of 21 CFR Part 

11. An electronic signature function can also be used in conjunc-

tion with SIMATIC Logon.

All previous versions can be upgraded to the current version.

■

The optional chipcard reader can be used for access control in 

addition to the keyboard. SIMATIC Logon additionally supports 

logon devices which can be operated with a Microsoft device 

driver for the respective operating system (e.g. logon devices on 

a USB interface). It is also possible to connect logon devices via 

a separately created device-specific drive.
The number of SIMATIC Logon licenses required depends on 

the number of clients/single stations that access applications for 

which SIMATIC Logon is used for access protection.
SIMATIC Logon was developed for the SIMATIC PCS 7 process 

control system but can also be used together with other SIMATIC 

products in the context of Totally Integrated Automation (TIA), 

e.g. with SIMATIC WinCC. A requirement for working together is 

that user groups have already been created in the partner appli-

cations, or can be defined.

■

Using the SIMATIC Logon Admin Tool it is possible to assign the 

roles defined in the SIMATIC PCS 7 applications (e.g. Automa-

tion License Manager and SIMATIC BATCH) to the Windows 

users/user groups. Administrators with the necessary Windows 

administrator privileges can also use the SIMATIC Logon Admin 

Tool to edit Windows users and user groups.

The login dialog of the SIMATIC Logon Service is activated when 

an application is started which is managed by SIMATIC Logon. 

The user receives his specific privileges after making the login, 

password and domain entries. The SIMATIC Logon Service dia-

log for logoff, user change or password edit can be called in the 

applications.

The SIMATIC Electronic Signature means that operations cannot 

be performed until enabled by previously assigned Windows 

users/user groups. Users/user groups are assigned to the oper-

ations in the respective application. 
At the moment this function is implemented as a system function 

only on SIMATIC BATCH. However, the Electronic Signature can 

be used on any products in the specific applications.
The software products listed here under "Selection and ordering 

data" are only relevant to use in the TIA environment.
