7.2 Configuring access protection for the CPU
Configuring access levels
To set the access levels for the CPU by means of parameter assignment, follow these steps:
1. Open the properties of the CPU in the Inspector window.
2. Select the "Protection & Security" area.
A table with the possible access levels appears in the Inspector window.
Figure 7-1 Possible access levels
3. Activate the desired protection level in the first column of the table. The green check
marks in the columns to the right of the respective access level show you which
operations are still available without entering the password. In the example (Figure:
Possible access levels), read access and HMI access are still possible without a
password.
4. In the "Enter password" column, specify a password for the access level "Full access" in
the first row. In the "Confirm password" column, enter the selected password again to
guard against incorrect entries.
5. Assign additional passwords as required for other access levels.
6. Download the hardware configuration for the access level to take effect.
The CPU logs the following actions with an entry in the diagnostic buffer:
● Input of the correct or incorrect password
● Changes to access level configuration
