edundancy Protocol
in accordance with IEC 62439-3) are used to connect up to two
non-HSR-enabled terminal devices or network segments to a
ring-shaped HSR network structure. They can also be used for
simple and redundant transition from HSR to PRP (Parallel
Redundancy Protocol) network structures.
•
Electrical or optical connection to stations or network in
accordance with the port type of the devices
•
Media redundancy thanks to duplicate transmission of frames
in ring-shaped networks
•
High system availability since frames are sent simultaneously
via two routes in the ring
•
No reconfiguration times of the ring-shaped network are
required in the event of an error due to duplicate transmission
of frames in the ring
•
Simple and redundant connection of HSR and PRP network
structures
•
Redundant 24 V DC voltage infeed or wide-range power
supply unit, depending on device version
•
SNMP access, integrated Web server and automatic e-mail
transmission function for remote diagnostics and signaling via
the network
Product versions
•
Network access point in plastic enclosure with electrical ports
-
SCALANCE X204RNA for HSR networks;
for connecting up to two non-HSR-enabled terminal devices
to ring-topology networks with four electrical ports
•
Network access point in metal enclosure with electrical and
optical ports, as well as a wide-range power supply unit for
use under extended ambient conditions
-
SCALANCE X204RNA EEC for HSR networks;
for connecting up to two non-HSR-enabled terminal devices
to ring-shaped networks with two electrical terminal device
ports and two optical/electrical combo ports for network
connection
-
SCALANCE X204RNA EEC for PRP or HSR networks;
for connecting up to two non-PRP-enabled or non-HSR-
enabled terminal devices to redundant networks with two
electrical terminal device ports and two optical/electrical
combo ports for network connection. PRP or HSR function
can be defined by the user when starting the device (for
description of PRP function, see Section on X204RNA with
PRP function).

Benefits
•
Ideal solution for establishing Industrial Ethernet networks with
high network availability (bumpless media redundancy
through parallel data transfer in parallel network topologies)
•
Bumpless data transmission in ring-shaped network struc-
tures for high availability systems (e.g. process automation)
•
Fast and easy diagnosis with LEDs on the device, through the
integral Web server and through signaling contacts
•
Integration of the SCALANCE X-200RNA network access
points into the existing network management infrastructure
through SNMP access
•
Simple commissioning without mandatory configuring
•
Module replacement without the need for a programming
device, using the C-PLUG swap media for backing up the
configuration data
■
Application
The SCALANCE X-200RNA Industrial Ethernet network access
points with HSR functionality enable low-cost connection of
non-HSR-enabled terminal devices to ring-shaped networks in
which high availability is demanded. The devices with degree of
protection IP20 are designed for operation in the control cabinet.
Features:
•
Device diagnostics with LEDs (power, link status, data
communication)
•
Remote diagnostics possible via signaling contact
(signal screen can be set locally using buttons),
SNMP, and Web browser
•
With its extended ambient conditions, the SCALANCE
X204RNA EEC is suitable for use in power switching and
distribution systems (IEC 61850-3, IEEE 1613) in tough
industrial environments
