Protection levels of the CPU
If you configure a protection level ≥ 2 in the configuration of the CPU ("Options” tab), this has
the following effects on the operation of the CP:
• Initialization of the CP / assigning an IP address using a different method
Using the Primary Setup Tool (PST) / SINEC PNI, you can only assign an IP address to the CP
once.
• No PST / SINEC PNI with IP configuration using DHCP or in the user program
If you have configured the setting of the IP addresses of the CP from a DHCP server or
using the user program (IP_CONFIG), you cannot assign an IP address to the CP via PST /
SINEC PNI.
• Formatting the C-PLUG
It is not possible to format the C-PLUG of the CP during operation of the station.
Set the CPU to STOP to perform this action.
• Resetting / memory reset
It is not possible to reset or to reset the memory of the CP during operation of the station.
Set the CPU to STOP to perform this action.

CP "EX11" or "GX11":
A change between data storage on the CPU and data storage on the CP is not possible.
