Discovery and
configuration
DCP is used by PROFINET to determine
PROFINET devices and to make basic
settings.
DCP uses the special multicast MAC ad-
dress:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique Identi-
fier

LLDP is used by PROFINET to determine
and manage neighborhood relationships
between PROFINET devices.
LLDP uses the special multicast MAC
address:

MRP enables the control of redundant
routes through a ring topology.
MRP uses the special multicast MAC
address:

PTC allows a time delay measurements to
be made between RJ45 ports – therefore
send cycle synchronization and time syn-
chronization.
PTCP uses the special multicast MAC
address:

The PROFINET IO telegrams are used to
cyclically transfer I/O data between the
PROFINET IO controller and IO devices
via Ethernet.
