Configuring access protection for the CPU

Introduction
The CPU provides you with various 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 as well as their associated
passwords are specified in the object properties of the CPU.
Rules for passwords
Ensure that passwords are sufficiently secure. Passwords must not follow a machine-
recognizable pattern.
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.
