Address label: Unique MAC address preset for the CP
The CP is supplied with total of 3 default MAC addresses with the following assignment:
● PROFINET interface
● 1 MAC address for each port of the PROFINET interface
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 addresses 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.
