Assignment of the MAC addresses
The MAC address is a globally unique device identifier that is assigned to each PROFINET
device in the factory. Its 6 bytes are divided into 3 bytes for the manufacturer ID and 3 bytes
for the device ID (serial number). The front of the CPU 1510SP-1 PN is lasered with the
MAC address of the PROFINET interface.
The PROFINET interface (X1) of the CPU 1510SP-1 PN has three ports. Port 3 is located on
the CPU. Ports 1 and 2 are located on the optional BusAdapter. In addition to the
PROFINET interface, each PROFINET port also has a separate MAC address. There is
therefore a total of four MAC addresses for the CPU 1510SP-1 PN.
The MAC addresses of the PROFINET ports are needed for the LLDP protocol, for example
for the neighborhood discovery function.
The table below shows how the MAC addresses are assigned.
