Connection of Ethernet devices to a switching hub
The following figure shows connection of Ethernet devices to a TSN switching hub and general-purpose switching hubs.
No.0
Class B (1 Gbps)
No.0: Motion module (master station)
No.1: Servo amplifiers (remote station)
No.2: Remote I/O module (remote station)
No.3: Inverter (remote station)
(1), (2), (3), (4), (5): Ethernet device
• The Ethernet devices can be connected to the general-purpose switching hub connected to the end of the
line topology.
• 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 21 Performance Specifications of Ethernet
• When connecting the Ethernet device (100 Mbps), use switching hubs that support the communication
speed of 1 Gbps/100 Mbps.
• The CC-Link IE TSN Class B devices cannot be used by connecting them to the general-purpose switching
hubs 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.
