*1 For a device station with a communication speed of 100Mbps, set "Communication Period Setting" to "Basic Period" or "Normal-Speed".
*2 When the device is connected on the end side via the switching hub as shown below, communication may not be possible depending on
the type of the device.
The communication will be enabled by configuring settings with the switching hub so that the multicast frame (with multicast MAC
address 09:00:70:00:10:02 and 09:00:70:00:10:05) will not be transferred to the ports specified below.
Connection structure that cannot be communicated
A local station and Ethernet device coexist.
The local station and CC-Link IE TSN Class A remote station are mixed.
*3 For a local station or remote station of a device on the master station side, use a device supporting the multicast filter. ( Manual for
the device used)
Precautions
When a TSN hub is used, check the TSN hub specifications on the CC-Link Partner Association website (www.cc-link.org).
