Connection of Ethernet devices to an industrial switch
The configuration for connecting Ethernet devices to industrial switches (for CC-Link IE TSN Class B) and industrial switches
(for CC-Link IE TSN Class A) in the configuration is shown below.
• The Ethernet devices can be connected to the industrial switch (for CC-Link IE TSN Class A) connected to
the end of the line topology. The Ethernet devices can also be connected to an industrial switch (for CC-Link
IE TSN Class B) in the network or an industrial switch (for CC-Link IE TSN Class A) connected to the
industrial switch (for CC-Link IE TSN Class B).
• The Ethernet devices can perform MELSOFT connection and SLMP communications with the master
station. They also can communicate with each other using a protocol that supports each other. For the
maximum number of MELSOFT connection and SLMP communications, refer to the following.
Page 17 Performance Specifications of Ethernet
• When connecting the Ethernet device (100Mbps), use an industrial switch that supports the communication
speed of 1Gbps/100Mbps.
• The CC-Link IE TSN Class B devices cannot be used by connecting them to the industrial switches (for CC-
Link IE TSN Class A) installed for Ethernet device connection. CC-Link IE TSN Class A devices can be
used by connecting to them.
• Since Ethernet communications use the transient transmission band on CC-Link IE TSN, the throughput of
the Ethernet communications may decrease when the basic communication cycle is extremely short or
when a large number of packets are communicated. This can be solved by correcting the communication
frequency and the number of connected Ethernet devices.
