Troubleshooting Related to CC-Link IE TSN

Cyclic transmission failed
The following lists the actions to be taken if cyclic transmission cannot be performed.
Check item
Is the D LINK LED of the CC-Link IE TSN Plus module turned on?
Do the station types set in "Network Configuration Settings" under "Basic
Settings" of the master station match those set for the connected slave
stations?
When "Connection Device Information" under "Basic Settings" is set to "CC-
Link IE TSN Class B Only", is a dedicated TSN hub used?
When "Communication Speed" under "Application Settings" of the master
station is set to "100Mbps", is "System Reservation Time" in "Communication
Period Setting" under "Basic Settings" of the master station set to 20s?
Is "  " displayed on the dot matrix LED of the CC-Link IE TSN Plus
module?
When "Connection Are CC-Link IE TSN Class A devices connected?
Device Information"
under "Basic Settings" of
the master station is set
to "CC-Link IE TSN
Class B Only"
Is a general-purpose hub connected between CC-
Link IE TSN Class B devices?
When "Connection Are nine or more CC-Link IE TSN Class B devices
Device Information" and TSN hubs connected in total to each port of
under "Basic Settings" of the master station in the transmission path from
the master station is set the master station to the CC-Link IE TSN Class B
to "Mixture of CC-Link IE device of the end?
TSN Class B/A or CC-
Is a CC-Link IE TSN Class B device other than the
Link IE TSN Class A
master station connected in a star topology via a
Only"
general-purpose hub?
Is a CC-Link IE TSN Class B device connected to
the master station via a general-purpose hub?
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 "02" or later
Is the event code 00C81 registered in the event
history?
Action
Perform troubleshooting for when the D LINK LED turns off or is flashing.
( Page 365 When the D LINK LED turns off or is flashing)
Check 'Station type match status of each station' (SB00E8) and 'Station type
match status' (SW00E8 to SW00EF) to correct the station type of stations in
which the station type does not match.
• Correct the used switching hub and the switching hub settings. For the
setting method, refer to the manual for the switching hub used.
• When using a TSN hub, check the precautions and restrictions for system
configuration on the CC-Link Partner Association website (www.cc-link.org).
• Correct the switching hub delay time according to the switching hub used.
( Page 526 Communication cycle intervals) For the switching hub delay
time, refer to the manual for the switching hub used.
Set "System Reservation Time" to 200s.
Set the module parameters.
• Check the connected device and disconnect the CC-Link IE TSN Class A
devices.
• When connecting a CC-Link IE TSN Class A device, set "Connection
Device Information" of the master station to "Mixture of CC-Link IE TSN
Class B/A or CC-Link IE TSN Class A Only".
Check the connected device and disconnect the general-purpose hub or
replace it with a TSN hub.
Check the connected devices 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 CC-Link IE TSN Class A remote station to a local station or
remote station supporting the multicast filter.
• 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 Setting" on the slave station side so that
"CC-Link IE TSN Class Setting" for each station match.
