Address label: Unique MAC address preset for the CP
The CP is supplied with a MAC address preset in the factory for the PROFINET
interface.
The gigabit interface has its own default MAC address.
The MAC addresses are 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!
S This ensures that you assign a unique MAC address in the subnet!
S 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.
