[?-]: How to protect blocks REALLY in S7-300?

[Scarch]

Is there any protection other than the ridiculous know-how protect?
I mean to protect the blocks of the program with a password, similar than with the S7-200.
In the Simatic manager I see "access protection" but can not use that menu.
do I need to install some other software?
Many thanks

Hello,

Look at http://support.automation.siemens.com/W ... n/10154913 . Only one thing - all doors have keys (somewhere). Sometimes even is not necessary.

With regards,
Umencho

No, I mean to protect BLOCKS separately using other protection than the know-how

dear Scarch to use menu "access protection" in step7. It is necessary in addition to install program "simatic logon" http://support.automation.siemens.com/W ... 2&x=24&y=8
