Assignment of MAC addresses
The CPU 1511-1 PN has a PROFINET interface with two ports. The PROFINET interface
itself has a MAC address, and each of the two PROFINET ports has its own MAC address.
There are therefore three MAC addresses in total for the CPU 1511-1 PN.
The MAC addresses of the PROFINET ports are needed for the LLDP protocol,
for example for the proximity detection function.
The number range of the MAC addresses is sequential. The first and last MAC address
is lasered on the right of each CPU 1511-1 PN.
The table below sets out the MAC address assignment.
