4.2.11.2 Protocols used
The converter supports the protocols listed in the following tables. The address parameters, the
relevant communication layer as well as the communication role and the communication
direction are specified for each protocol.
You require this information to set the appropriate safety measures to protect the automation
system, e.g. in the firewall.
As the security measures are limited to Ethernet and PROFINET networks, no PROFIBUS
protocols are listed in the table.

Accessible stations, PROFINET Discovery and configuration
DCP is used by PROFINET to determine PROFINET devices and to
make basic settings.
DCP uses the special multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique Identifier
LLDP:
Link Layer Dis‐
covery Protocol
Not rele‐
vant
(2) Ethernet II and
IEEE 802.1Q and
Ethertype 0x88CC
(PROFINET)
PROFINET Link Layer Discovery protocol
LLDP is used by PROFINET to determine and manage neighborhood
relationships between PROFINET devices.
LLDP uses the special multicast MAC address:
01-80-C2-00-00-0E
MRP:
Media Redun‐
dancy Protocol
Not rele‐
vant
(2) Ethernet II and
IEEE 802.1Q and
Ethertype 0x88E3
(PROFINET)
PROFINET medium redundancy
MRP enables the control of redundant routes through a ring topology.
MRP uses the special multicast MAC address:
xx-xx-xx-01-15-4E,
xx-xx-xx = Organizationally Unique Identifier
