9.2 Security levels
You can define a protection level for your project in order to prevent unauthorized access to
the CPU programs. The objective of these protection level settings is to grant a user access
to specific programming device functions which are not protected by password, and to allow
that user to execute those functions on the CPU.
Setting protection levels
You can set the CPU protection levels 1 to 3 in HW Config.
The following table shows the protection levels of a CPU.
