Description
PROFINET protocols
DCP
Discovery and Configura-
tion Protocol
Not relevant
(2) Ethernet II, Ethertype 0x8892 DCP is used by PROFINET to de-
termine PROFINET devices and to
facilitate the basic fundamental set-
tings.
DCP uses the special Multicast-MAC
address:
01-0E-CF-00-00-0x, whereby x = 0:
Identify and x = 1: Hello
LLDP
Link Layer Discovery
Protocol
Not relevant
(2) Ethernet II, Ethertype 0x88CC LLDP is used by PROFINET to de-
termine and manage relationships
between the various PROFINET
devices.
LLDP uses the special Multicast-
MAC address:
01-80-C2-00-00-0E
MRP
Media Redundancy Proto-
col
Not relevant
(2) Ethernet II, Ethertype 0x88E3 MRP facilitates the control of redun-
dant communication paths through a
ring topology.
MRP uses the special Multicast-MAC
address:
01-15-4E-00-00-0x, whereby x = 1:
MC_Test and x = 2: MC_Control
PROFINET IO data
Not relevant
(2) Ethernet II, Ethertype 0x8892 PROFINET IO-telegrams are used
to transfer IO data cyclically between
PROFINET IO-Controller and IO-
Devices via Ethernet.
