概述
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);
最多可以提供电气和/或光学2端口介质模块
inserted at any position in the basic unit
•
通过积分冗余的高速介质冗余
manager both for Gigabit Ethernet (with SCALANCE X-300,
X-400) and Fast Ethernet (e.g. in combination with
SCALANCE x - 200开关)
•
自动化网络与现有的无缝集成
corporate networks thanks to support for a host of IT standard
functions (VLANs, IGMP-Snooping/Querier, STP/RSTP, Link
聚合，服务质量）
•
凭借的冗余集成到更高级别的网络
support for standardized redundancy procedures (Spanning
Tree Protocol/Rapid Reconfiguration Spanning Tree Protocol/
MRP)
•
通过PROFINET诊断，远程诊断，
Web浏览器，CLI或SNMP
■
好处
•
网络扩建期间的无限灵活性（例如，更多
terminals) or conversion (e.g. switching from copper to fiber-
光缆）和降低储存成本
使用端口模块的模块化施工
•
High availability of the network thanks to:
- Redundant power supply
- 基于光纤的冗余网络结构或
双绞线电缆（冗余管理器，待机功能，
和STP / RSTP已集成）
-
Easy device replacement by means of plug-in C-PLUG swap
medium
- 在发生故障时非常快速地重新配置网络
•
Lower susceptibility to failure and higher availability of the
由于RJ45 FastConnect的闭锁，植物网络
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-
步骤7中的分配和诊断，没有额外的软件
•
Space savings in control cabinet due to flexible cable outlet
on the front or rear of the device

Application
SCALANCE XR-300非常适用于植物网络和
for integrating the industrial network into an existing corporate
网络。两者均在现场等级和控制级别，开关
performs the network with the distributed field devices and
通过广泛的诊断选项确保高植物可用性
和高传输速度。模块化允许完美
通过使用适应各自的应用
electrical and also optical media modules
The SCALANCE XR-300 switch is suitable for establishing elec-
TRICK和光学工业以太网线，星形或环形拓扑
拥有24个港口，可选择配备电气
和/或光学2端口介质模块。它也可以用作
厂家总线中的集线器（冗余连接是可能的）。
