Overview of the protective functions of the CPU
Introduction
This chapter describes the following functions for protecting the S7-1500 automation system
against unauthorized access:
● Access protection
● Know-how protection
● Copy protection
● Protection by locking the CPU
Further measures for protecting the CPU
The following measures additionally increase the protection against unauthorized access to
functions and data of the S7-1500 CPU from external sources and via the network:
● Deactivation of the Web server
● Deactivation of the time synchronization via an NTP Server
● Deactivation of the PUT/GET communication
When the Web server is used, you protect your S7-1500 automation system against
unauthorized access by setting password-protected access rights for specific users in the
user management.

Configuring access protection for the CPU
Introduction
The CPU offers four access levels, in order to limit access to specific functions.
By setting up the access levels and the passwords for a CPU, you limit the functions and
memory areas that are accessible without entering a password. The individual access levels
as well as the entry of their associated passwords are specified in the object properties of
the CPU.
