5 SYSTEM CONFIGURATION
5.4 Structure of CC-Link IE TSN Class B/A Devices (CC-Link IE TSN Protocol Version 1.0 Only) and Ethernet Devices
Structure of unicast mode
This mode indicates the availability of connection with a network configuration device when "Communication Mode" under
"Application Settings" is set to "Unicast".
When the communication speed for the master station is set to 1Gbps
The following table lists the availability of connection with a network configuration device when the communication speed for
the master station is set to 1Gbps.
: Connection available, : Connection available via an industrial switch, : Connection not available
S: Industrial switches (for CC-Link IE TSN Class B) can be used.
H: Industrial switches (for CC-Link IE TSN Class A) can be used.
*1 For a device station with a communication speed of 100Mbps, set "Communication Period Setting" to "Low-Speed".
*2 Connection cannot be made if the total cyclic data size of all device stations on the CC-Link IE TSN Class A device side that form a
boundary between CC-Link IE TSN Class B and CC-Link IE TSN Class A devices exceeds 2K bytes. ( Page 124 Calculation of the
total cyclic data size)
*3 If the firmware version of the master station is "1.002" or earlier, only one of P1 or P2 can be used. When using both P1 and P2,
configure the system with the devices that support the multicast mode. (Page 100 Structure of multicast mode)
*4 A connection cannot be established if the total cyclic data size of all device stations on the 100Mbps device side exceeds 2K bytes. This
includes the devices with a communication speed of 100Mbps that form a boundary between the communication speed of 1Gbps and
100Mbps. ( Page 124 Calculation of the total cyclic data size)
When an industrial switch (for CC-Link IE TSN Class B) is used, check the industrial switch (for CC-Link IE TSN Class B)
specifications on the CC-Link Partner Association website (www.cc-link.org).
