Ethernet And Profinet Protocols That Are Used - Siemens SINAMICS G110M Function Manual

Introduction

2.1 Ethernet and PROFINET protocols that are used

2.1 Ethernet and PROFINET protocols that are used
The inverter 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.

Layer Function/description
(2) Link layer
(4) Transport layer
(2) Ethernet II and Accessible stations, PROFINET Discovery and configuration
IEEE 802.1Q and
DCP is used by PROFINET to determine PROFINET devices and to
Ethertype 0x8892
make basic settings.
(PROFINET)
DCP uses the special multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique Identifier
(2) Ethernet II and PROFINET Link Layer Discovery protocol
IEEE 802.1Q and
LLDP is used by PROFINET to determine and manage neigh-
Ethertype 0x88CC
borhood relationships between PROFINET devices.
(PROFINET)
LLDP uses the special multicast MAC address:
01-80-C2-00-00-0E
(2) Ethernet II and PROFINET medium redundancy
IEEE 802.1Q and
MRP enables the control of redundant routes through a ring topolo-
Ethertype 0x88E3
gy.
(PROFINET)
MRP uses the special multicast MAC address:
xx-xx-xx-01-15-4E,
xx-xx-xx = Organizationally Unique Identifier
(2) Ethernet II and PROFINET send clock and time synchronization, based on IEEE
IEEE 802.1Q and 1588
Ethertype 0x8892
PTC is used to implement send clock synchronization and time syn-
(PROFINET)
chronization between RJ45 ports, which are required for IRT opera-
tion.
PTCP uses the special multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique Identifier
(2) Ethernet II and PROFINET Cyclic IO data transfer
IEEE 802.1Q and
The PROFINET IO telegrams are used to transfer IO data cyclically
Ethertype 0x8892
between the PROFINET IO controller and IO devices via Ethernet.
(PROFINET)
(4) UDP PROFINET connection less RPC
The PROFINET context manager provides an endpoint mapper in
order to establish an application relationship (PROFINET AR).
