6.13 Communication services and used port numbers
The drive device supports the protocols listed in the following table. The address
parameters, the relevant communication layer as well as the communication role and the
communication direction are specified for each protocol.
This information allows you to match the security measures for the protection of the
automation system to the used protocols (e.g. firewall). As the security measures are limited
to Ethernet and PROFINET networks, no PROFIBUS protocols are listed in the table.
The following table shows the various layers and protocols that are used.

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

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

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

xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique
