managed Industrial Ethernet network access points with PRP
functionality (

rotocol in accordance with
IEC 62439-3) are used to connect up to two non-PRP-enabled
terminal devices or network segments to parallel networks.
•
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 two parallel, separate networks
•
High system availability since frames are sent simultaneously
over two separate networks
•
Reconfiguration times in a subnetwork do not affect the
propagation time because the frames are transmitted via two
separate networks (bumpless redundancy)
•
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 PRP networks;
for connecting up to two non-PRP-enabled terminal devices
to redundant 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 PRP networks;
for connecting up to two non-PRP-enabled terminal devices
to redundant 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 HSR function, see Section on X204RNA
with HSR function).

Benefits
•
Ideal solution for establishing Industrial Ethernet networks with
high network availability (bumpless media redundancy
through parallel data transfer in parallel network topologies)
•
The reconfiguration time of a subnetwork does not influence
frame transmission
•
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 enable low-cost connection of non-PRP-enabled terminal
equipment to parallel, separate networks in which high availabil-
ity 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
