Direct connection of Ethernet devices
The following figure shows direct connection of Ethernet devices to CC-Link IE TSN-compatible devices.
• The Ethernet devices (1Gbps) can be directly connected to unused ports of the CC-Link IE TSN-compatible
devices without the industrial switch.
• 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
• Since the CC-Link IE TSN-compatible devices have a smaller memory capacity for packet reception
compared to the industrial switches, packets may not reach external devices if the Ethernet devices are
directly connected and high-frequent communications are performed. This can be solved by using an
industrial switch (for CC-Link IE TSN Class B) and expanding the memory capacity for packet reception.
