SCALANCE XB-200 Web Based Management

The SCALANCE XB-200 IE switches have the following properties:
● The Ethernet interfaces support the following modes:
– 10 Mbps and 100 Mbps both in full and half duplex
– Autocrossing
– Autopolarity
● EtherNet/IP
EtherNet/IP (Ethernet/Industrial Protocol) is an open industry standard for industrial real-
time Ethernet based on TCP/IP and UDP/IP.
● PROFINET IO
PROFINET (Process Field Network) is an open industry standard for industrial real-time
Ethernet based on TCP/IP and IT standards. Via PROFINET IO (Input/Output) distributed
IO devices can be connected to a controller.
● The Rapid Spanning Tree Protocol (RSTP) and the Spanning Tree Protocol (STP)
redundancy methods
The redundancy mechanism Spanning Tree defines several connection paths between
nodes in a network, only one of which is ever active. This suppresses loops and
optimizes the paths.
● Virtual networks (VLAN)
To structure Industrial Ethernet networks with a fast growing number of nodes, a physical
network can be divided into several virtual subnets.
● Load limitation when using multicast and broadcast protocols, for example video
transmission
By learning the multicast sources and destinations (IGMP snooping, IGMP querier), IE
switches can filter multicast data traffic and so reduce the load in the network. Multicast
and broadcast data traffic can be limited.
● Time-of-day synchronization
Diagnostics messages (log table entries, e-mails) are given a time stamp. The local time
is uniform throughout the network thanks to synchronization with a SICLOCK time
transmitter or SNTP/NTP server and therefore makes the identification of diagnostics
messages of several devices easier.
● Quality of Service for classification of the network traffic is according to CoS (Class of
Service - IEEE 802.11Q) and DSCP (Differentiated Services Code Point - RFC 2474)
