 CC-Link IE TSN Class B device area
 CC-Link IE TSN Class A device area
• The Ethernet devices (1 Gbps) can be directly connected to unused ports of the CC-Link IE TSN-compatible
devices without the switching hub.
• The Ethernet devices (100 Mbps) can be connected to the general-purpose switching hub on the boundary
between the CC-Link IE TSN Class B and CC-Link IE TSN Class A areas.
• 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
• Since the CC-Link IE TSN-compatible devices have a smaller memory capacity for packet reception
compared to the switching hub, packets may not reach external devices if the Ethernet devices are directly
connected and high-frequent communications are performed.
• 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.
