Overview
The SCALANCE XR-300EEC (
E
nhanced
E
nvironmental
C
onditions) industrial Ethernet switches are partly modular, high-
performance, industry-standard switches for the construction of
electrical and/or optical line, ring and star topologies at 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), of which 16 are integral RJ45 ports;
up to four electrical and/or optical 2-port media modules can
also be inserted in the media module slots of the basic device
•
Suitable for use in extremely harsh industrial environments
and in low-voltage and high-voltage switchgear thanks to:
- Extended temperature range
(-40 to +70 °C, briefly to +85 °C)
- Support for special protocols and standards
(IEEE 1613 and IEC 61850-3)
- Wide-range power supplies (60 to 250 V AC/DC)
•
High-speed media redundancy through integral redundancy
manager both for Gigabit Ethernet and Fast Ethernet
•
Seamless integration of automation networks into existing
corporate networks thanks to support for a host of
IT standards (VLANs, IGMP-Snooping/Querier, STP/RSTP,
Link Aggregation, Quality of Service)
•
Remote diagnostics by means of PROFINET diagnostics,
Web browser, CLI, or SNMP

■
Benefits
•
Increased availability of the network due to hardware and
software functions specially geared to the particular require-
ments of energy technology plants and extreme environ-
mental conditions
•
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
■
Application
The SCALANCE XR-300EEC is ideal for use in plant networks
and for integrating the industrial network into an existing corpo-
rate 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/or optical media modules.
The main area of application is found in high-performance
plant networks with interfaces to the corporate network.
Thanks to the immunity to electromagnetic interference of the
SCALANCE XR-300EEC switches, the devices can also be used
in medium/high voltage substations.
The SCALANCE XR-300EEC switch is suitable for establishing
optical Industrial Ethernet line, star or ring topologies with
24 ports, 16 of which are integrated RJ45 ports. Up to four
electrical and/or optical 2-port media modules can also be
inserted in the media module slots of the basic device.
The switch can also be used as a hub in the plant bus (redun-
dant connection is possible).
The use of media modules in partly and fully modular versions of
the SCALANCE X-300 switches supports:
•
Extension of networks by subsequent insertion of additional
media modules in unused media module slots
•
Changing of cabling technology, such as conversion from
copper to fiber-optic cables, or from multimode to single-
mode FOC
