Overview
The SCALANCE XR-300 Industrial Ethernet switches are fully
modular, high-performance, industry-standard switches for the
construction of electrical and optical line, ring and star topol-
ogies with data transfer rates of 10/100/1 000 Mbit/s, designed
for installation in 19" control cabinets.
•
As many as 24 electrical and/or optical interfaces
(10/100/1 000 Mbit/s);
up to12 electrical and/or optical 2-port media modules can be
inserted at any position in the basic unit
•
High-speed media redundancy through integral redundancy
manager both for Gigabit Ethernet (with SCALANCE X-300,
X-400) and Fast Ethernet (e.g. in combination with
SCALANCE X-200 switches)
•
Seamless integration of automation networks into existing
corporate networks thanks to support for a host of IT standard
functions (VLANs, IGMP-Snooping/Querier, STP/RSTP, Link
Aggregation, Quality of Service)
•
Redundant integration into higher-level networks thanks to
support for standardized redundancy procedures (Spanning
Tree Protocol/Rapid Reconfiguration Spanning Tree Protocol/
MRP)
•
Remote diagnostics by means of PROFINET diagnostics,
Web browser, CLI, or SNMP
■
Benefits
•
Unlimited flexibility during network expansions (e.g. more
terminals) or conversion (e.g. switching from copper to fiber-
optic cable) and reduction of the storage costs due to the
modular construction using port modules
•
High availability of the network thanks to:
- Redundant power supply
- Redundant network structures based on fiber-optic or
twisted pair cables (redundancy manager, standby function,
and STP/RSTP are integrated)
-
Easy device replacement by means of plug-in C-PLUG swap
medium
- Very fast reconfiguration of the network in the event of a fault
•
Lower susceptibility to failure and higher availability of the
plant networking due to latching of the RJ45 FastConnect
connectors in the sleeve of the RJ45 port modules
•
Protection of investment due to integration into existing
network management systems by means of standardized
SNMP access
•
Time saving during engineering, commissioning and in the
operating phase of a plant by using the integrated configu-
ration and diagnostics in STEP 7, without additional software
•
Space savings in control cabinet due to flexible cable outlet
on the front or rear of the device
■
Application
The SCALANCE XR-300 is ideal for use in plant networks and
for integrating the industrial network into an existing corporate
network. Both at the field level and the control level, the switch
performs the network with the distributed field devices and
ensures high plant availability with extensive diagnostics options
and high transmission speeds. The modularity permits perfect
adaptation to the respective application through the use of
electrical and also optical media modules
The SCALANCE XR-300 switch is suitable for establishing elec-
trical and optical Industrial Ethernet line, star or ring topologies
with 24 ports that can be optionally equipped with electrical
and/or optical 2-port media modules. It can also be used as a
hub in the plant bus (redundant connection is possible).
The SCALANCE XR324-12M TS (TS = Transportation Systems)
is suitable for use in railway applications due to its specification
according to EN 50155.
