Configuring access levels
Proceed as follows to configure the access levels for the CPUs:
1. Open the properties of the CPUs in the Inspector window.
2. Open "Protection & Security" in the area navigation.
A table with the possible access levels appears in the Inspector window.
Figure 9-1 Possible access levels
3. Activate the required protection level in the first column of the table. The green check
marks in the columns to the right of the access level show which operations are still
possible 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
including failsafe" in the first row. In the "Confirm password" column, enter the selected
password again to avoid 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 CPUs log the following actions with an entry in the diagnostics buffer:
● Input of the correct or incorrect password
● Changes to access level configuration
