4.4 Troubleshooting by Symptom
■For firmware version "13" or earlier
Are nine or more CC-Link IE TSN Class B devices and
TSN hubs connected in total to 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?
Is the CC-Link IE TSN Class B device other than 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?
■When connected devices are protocol version 2.0
Is the event code 00C80 registered in the event history?
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" under "Network Configuration
Settings" or CC-Link IE TSN Class settings on the slave station
side so that the CC-Link IE TSN Class settings 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.
Take one of the following actions.
• Check 'Station protocol version 2.0 support status' (SW01A0 to
SW01A7) and update the firmware of all slave stations to a
version that supports the protocol version 2.0. Alternatively,
replace with slave stations that support protocol version 2.0.
• For firmware version "15" or later, set 'Protocol setting'
(Un\G1294018) of the master station to '1: Protocol version 1.0
fixed'. ( Page 260 Protocol information (Un\G1294016 to
Un\G1294031))
• After powering on the slave stations and the devices on the
communication path, power on the master station.
