Delete access rights".
You can limit access to a password-protected CPU in the RUN mode locally in the display so
that access with a password is also not possible.On the display of an CPU, you can block access to a password-protected CPU
(local lock). The access lock is only in effect, when the mode selector is in the RUN position.
The access block requires a configured protection level in STEP 7. The access block is
effective regardless of the password protection. This means that even if someone accesses
the CPU via a connected programming device and has entered the correct password,
access to the CPU remains disabled.
The access block can be set separately for each access level on the display, so that, for
example, read access is allowed locally, but write access is not allowed locally.If an access level with a password is configured in STEP 7, access can be blocked using the
display.
Proceed as follows to set the local access protection for an CPU on the display:
1. On the display, select Settings > Protection menu.
2. Confirm the selection using "OK", and configure for each access level, whether access at
the RUN mode selector is allowed or not:
Allow: Access to the CPU is possible with the corresponding password in STEP 7.
Disabled in RUN: When the mode selector is in the RUN position, no more users with
privileges for this access level can log in to the CPU, even if they know the password. In
STOP mode, access is possible with password entry.A password can be configured for the display in STEP 7 in the properties of the CPU so that
the local access protection is protected by a local password.In addition to restricting access to the display, you can also restrict access to a passwordprotected
CPU in STEP 7 using the instruction ENDIS_PW. You can find a description of this
block in the online help under the keyword "ENDIS_PW: Limit and enable password
legitimation". You can use know-how protection to protect one or more blocks of the OB, FB, FC type and
global data blocks in your program from unauthorized access. Enter a password to restrict
access to a block. The password offers high-level protection against unauthorized reading or
manipulation of the block.As an alternative to manual entry of password, you can connect a password provider to
STEP 7. When using a password provider, you select a password from a list of available
passwords. When a protected block is opened, STEP 7 connects to the password provider
and retrieves the corresponding password.
To connect a password provider you have to install and activate it. A settings file in which
you define the use of a password provider is also required.
A password provider offers you the following advantages:
● The password provider defines and manages the passwords. When know-how protected
blocks are opened, you work with symbolic names for passwords. A password is
