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 multicast mode
This mode indicates the availability of connection with a network configuration device when "Communication Mode" under
"Application Settings" is set to "Multicast".
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 Since cyclic data is sent to the Ethernet device when the Ethernet device is connected to the master station with the firmware version
"1.002" or earlier, communication may not be possible depending on the type of the Ethernet device.
*4 Since cyclic data is sent to a CC-Link IE TSN Class A remote station when the CC-Link IE TSN Class A remote station is connected to
the master station with the firmware version "1.002" or earlier, communication may not be possible depending on the type of the CC-Link
IE TSN Class A remote station.
*5 If the firmware version of the master station is "1.002" or earlier, only one of P1 or P2 of the master station can be used. When using
both P1 and P2 of the master station, connect a local station or remote station that supports multicast filtering as a device on the master
station side.
*6 Use the devices that support multicast filtering for the local stations or remote stations on the master station side. To check whether
multicast filtering is supported or not, refer to the user's manuals for the devices used.
*7 When the device is connected on the end side via the industrial switch 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 industrial switch 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.
