Media redundancy

Overview
The converter supports media redundancy based on MRP (Media Redundancy Protocol). Media
redundancy is a function to increase system availability through redundant communication
paths.
MRP can be expanded to MRPD (Media Redundancy with Planned Duplication of frames).
Requirement
The following preconditions apply regarding media redundancy:
• PROFINET as ring topology with redundancy manager
• Each device in the ring topology supports MRP or MRPD
• Maximum of 50 devices for each ring topology
• MRPD requires a suitable controller. In addition, a topology must be configured.

PROFINET Medium Redundancy
IEEE 802.1Q and
MRP enables the control of redundant routes through a ring topology.
Ethertype 0x88E3
MRP uses the special multicast MAC address:
(PROFINET)
xx-xx-xx-01-15-4E,
xx-xx-xx = Organizationally Unique Identifier
PROFINET send clock and time synchronization, based on IEEE 1588
IEEE 802.1Q and
PTCP enables the send clock synchronization and time synchronization
Ethertype 0x8892
between RJ45 ports required for IRT operation.
(PROFINET)
PTCP uses the special multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique Identifier
PROFINET cyclic IO data transfer
IEEE 802.1Q and
The PROFINET IO telegrams transfer process data cyclically between the
Ethertype 0x8892
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).
