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 Motion module turned on?
Does the device station support the link device set in "Network Configuration
Settings" of the master station?
Do the station types set in "Network Configuration Settings" under "Basic Settings"
of the master station match those set for the connected device 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 using an CC-Link IE TSN Class B/A device with a communication speed of
100 Mbps in the basic cycle, is "System Reservation Time" in "Communication
Period Setting" under "Basic Settings" of the master station set to other than 200
s?
When "Connection Device
Information" under "Basic
Settings" of the master station is
set to "CC-Link IE TSN Class B
Only"
When "Connected Device
Information" under "Basic
Settings" of the master station is
set to "Mixture of Authentication
CC-Link IE TSN Class B/A or
CC-Link IE TSN Class A Only"

4.4 Troubleshooting by Symptom
Are CC-Link IE TSN Class A devices
connected?
Is a general-purpose hub connected between
CC-Link IE TSN Class B devices?
■When the version of Add-on baseSystem is
"1.18" 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 with a
general-purpose hub in star topology?
Is the master station connected with CC-Link IE
TSN Class B devices via a general-purpose
hub?
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?
Action
Perform troubleshooting for when the D LINK LED turns off or is flashing.
( Page 141 When the D LINK LED turns off or is flashing)
Correct the link device to be assigned to the device station in "Network
Configuration Settings" of the master station.
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 275 Communication cycle interval) For the switching
hub delay time, refer to the manual for the switching hub used.
Set "System Reservation Time" to 200s.
• 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 ofCC-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 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 star topology.
• Connect CC-Link IE TSN Class B devices to a TSN hub.
• Check the connected device and connect the master station and CC-
Link IE TSN Class B devices in 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 using 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).
