Access protection example
You can choose from four different access levels in the TIA Portal to restrict user access to
functions and memory areas.
Figure 3-9
If you only want to allow users access over HMI, for example, select the access level "HMI
access" in the TIA Portal. Only HMI access and access to diagnostics data is then possible
without entering a password.
Users can read and write tags over an HMI device with this access level.
Users cannot:
● Download blocks or the hardware configuration to the CPU
● Upload blocks or the hardware configuration from the CPU to the PG/PC
● Run writing test functions
● Change the operating state from the PG/PC
● Run CPU firmware updates
