Communication via PROFINET IO
8.1.15.1
Communication services and port numbers used for PROFINET IO
The PROFINET boards of the SINAMICS G180 converter support the communication
protocols listed in the following table.
You require this information to match the security measures (e.g. a firewall) to protect the
automation system to the protocols being used.
(2) Link layer
(4) Transport layer
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:
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-
