Protection
8.2 Configuring access protection for the CPU
Parameterizing the procedure at access levels
To configure the access levels of an S7-1500 CPU, follow these steps:
1. Open the properties of the S7-1500 CPU in the Inspector window.
2. Open the "Protection" entry in the area navigation.
A table with the possible access levels appears in the Inspector window.
Figure 8-1 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.
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.
Ensure that the password is sufficiently secure, in other words, that is does not follow a
pattern that can be recognized by a machine!
5. Assign additional passwords as needed to other access levels if the selected access level
allows you to do so.
6. Download the hardware configuration for the access level to take effect.
The CPU logs the entry of the correct or incorrect password and any changes in the
configuration of the access levels by a corresponding entry in the diagnostics buffer.
