When "Connection ■For firmware version "13" or earlier
Device Information" Are nine or more CC-Link IE TSN Class B devices
under "Basic Settings" and TSN hubs connected in total to each port of
of the master station is the master station in the transmission path from the
set to "Mixture of CC- master station to the CC-Link IE TSN Class B
Link IE TSN Class B/A device of the end?
or CC-Link IE TSN
Is the CC-Link IE TSN Class B device other than
Class A Only"
the master station connected in a star topology via
a general-purpose hub?
Is the master station connected with CC-Link IE
TSN Class B devices via a general-purpose hub?
■For firmware version "13" or earlier
In multicast mode, is the CC-Link IE TSN Class A
remote station connected to the master station?
In multicast mode, is the CC-Link IE TSN Class A
remote station connected to a local station or
remote station that does not support the multicast
filter?
In multicast mode, are a local station and a CC-
Link IE TSN Class A remote station connected on
the end side via a switching hub?
Is an Ethernet device connected to places other
than the end of the network?
Does the connected switching hub support the CC-
Link IE TSN Class used?
■For firmware version "14" or later
Is the event code 00C81 registered in the event
history?
If the slave stations being used support protocol
version 2.0, is an master station that does not
support protocol version 2.0 being used?
Action
Check the connected device and reduce the number of CC-Link IE TSN Class
B devices and TSN hubs to eight or less in total for each port of the master
station in the transmission path from the master station to the CC-Link IE TSN
Class B device of the end.
• Other than the master station, do not connect CC-Link IE TSN Class B
devices to a general-purpose hub in the star topology.
• Connect CC-Link IE TSN Class B devices to a TSN hub.
• Check the connected device and connect the master station to CC-Link IE
TSN Class B devices in a line topology without using a general-purpose
hub.
• Check the connected device and connect the master station and CC-Link IE
TSN Class B devices to a TSN hub.
• Connect the local station or remote station supporting the multicast filter to
the CC-Link IE TSN Class A remote station.
• Set unicast mode.
• Configure 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 port of the CC-Link IE TSN Class A remote station.
• Check the connected device and do not connect both a local station and a
CC-Link IE TSN Class A remote station on the end side of the switching
hub.
• Set unicast mode.
Check the connected device and connect the Ethernet device at the end of the
network.
Use the switching hubs that support "CC-Link IE TSN Class Setting" set to the
master station. For the models and usage methods of the switching hubs,
refer to the CC-Link Partner Association website (www.cc-link.org).
Change "CC-Link IE TSN Class Setting" under "Network Configuration
Settings" or "CC-Link IE TSN Class" on the slave station side so that the CC-
Link IE TSN Class settings for each station match.
Update the master station to a firmware version that supports protocol version
2.0. Alternatively, replace with a master station that supports protocol version
2.0.
