Address label: Unique MAC address preset for the CP
The CP ships with a default MAC address. The MAC address is printed on the housing.
Address label: Unique MAC address for the CP
The CP is supplied with total of 3 default MAC addresses with the following assignment:
● PROFINET interface
● One MAC address for each of the 2 Ethernet ports of the PROFINET interface
The MAC addresses of the Ethernet ports are required only for detection and evaluation
of neighborhood and topology relations.
The MAC address of the PROFINET interface is printed on the housing.
If you configure a MAC address (ISO transport connections), we recommend that you use
the MAC address printed on the module for module configuration!
● This ensures that you assign a unique MAC address in the subnet!
● If you replace a module, the MAC address of the predecessor is adopted when you load
the configuration data; configured ISO transport connections remain operable.
You should also refer to the information in the section Replacing a module (Page 59).
