14.1 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 accesses
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.
