Configuring access protection for the CPU

Introduction
The following section describes how to use the various access levels of the CPUs. The
description applies to SIMATIC Drive Controllers up to CPU firmware version V3.0.
In later CPU firmware versions, use the local user management in the editor for users and
roles in the project tree. The access levels are represented there by function rights of the
same name which you assign to individual users via roles.
The SIMATIC Drive Controller offers you different access levels to limit access to specific
functions.
By setting up access levels and passwords, you limit the functions and memory areas that are
accessible without a password. The individual access levels and corresponding passwords are
specified in the object properties of the CPUs.
Rules for passwords
Ensure that passwords are sufficiently secure.
Apply the following rules:
• Assign a password that is at least 8 characters long.
• Use different cases and characters: uppercase/lowercase, numbers and special characters.
Access levels for the CPUs
Table 11- 1 Access levels and access restrictions
Access levels Access restrictions
Full access including Users of the TIA Portal and HMI applications will have access to all standard and failsafe functions.
failsafe
A password is not required.
(no protection)
Full access Users of the TIA Portal will have access to standard functions.
(no protection)
HMI applications can access all functions (failsafe and standard).
Required password:
For additional access to failsafe functions, the TIA Portal user must enter the password for "Full ac-
cess including failsafe".
Read access In this access level, only read access to the hardware configuration and the blocks is possible without
a password. HMI access and access to diagnostics data is also possible.
Neither blocks nor the hardware configuration can be downloaded to the CPUs without the pass-
word.
The following actions are not possible without the password either: Writing test functions and firm-
ware updates (online).
