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.

Function Description
Accessible DCP is used by PROFINET to determine
nodes, PROFINET devices and to make basic
settings.
PROFINET
Discovery and DCP uses the special multicast MAC
configuration address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique
Identifier
PROFINET LLDP is used by PROFINET to determine
Link Layer and manage neighborhood relationships
Discovery between PROFINET devices.
protocol
LLDP uses the special multicast MAC
address:
01-80-C2-00-00-0E
PROFINET MRP enables the control of redundant
medium routes through a ring topology.
redundancy
MRP uses the special multicast MAC
address:
xx-xx-xx-01-15-4E,
xx-xx-xx = Organizationally Unique
Identifier
PROFINET PTC allows a time delay measurements to
be made between RJ45 ports – therefore
send clock and
send cycle synchronization and time
time synchroni-
synchronization.
zation, based
on IEEE 1588 PTCP uses the special multicast MAC
address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique
