Troubleshooting by Symptom

This section describes troubleshooting by symptom. Perform the troubleshooting by symptom when a data link cannot be
performed with the target station even though no error occurs in the Motion module. If an error has occurred in the Motion
module, identify the error cause using the engineering tool. ( Page 129 Checking the Network Status)
When cyclic transmission cannot be performed
The following table lists the actions to be taken if cyclic transmission cannot be performed to the master station.
Check item
Is the D LINK LED of the Motion module turned on?
Do the station types set in "Network Configuration Settings" of the master station
match those set for the connected device stations?
When "Connection Device Information" is set to "CC-Link IE TSN Class B Only", is a
TSN switching hub used?
When "Communication Speed" of the master station is set to "100 Mbps", is "Basic
Settings"  "Communication Period Setting"  "Basic Period Setting"  "System
Reservation Time" of the master station set to 20 s?
Does the IP filter setting mistakenly block communications from the IP address of
another station?
The connection device
information of the master
station is set to "CC-Link
IE TSN Class B Only".
The connection device
information of the master
station is set to "Mixture of
CC-Link IE TSN Class B/A
or CC-Link IE TSN Class
A Only".

8.4 Troubleshooting by Symptom
Are CC-Link IE TSN Class A devices connected?
Is a general-purpose switching hub connected between
CC-Link IE TSN Class B devices?
■For firmware version "1.001" or earlier
Are nine or more CC-Link IE TSN Class B devices and
switching hubs connected in total in the transmission
path from the master station to the CC-Link IE TSN
Class B device of the end?
Is a CC-Link IE TSN Class B device connected to a
station other than the master station in a star topology
via a general-purpose switching hub?
Is a general-purpose switching hub connected between
the master station and CC-Link IE TSN Class B
devices?
Is an Ethernet device connected to a place other than
the end of the network?
Is a general-purpose switching hub other than the
NZ2EHG-T8(N) and DT135TX used?
■For firmware version "1.002" or later
Is the event code 00C81 registered in the event history?
When the device stations to be used operate with the
CC-Link IE TSN Protocol version 2.0, is a master
station that does not support the CC-Link IE TSN
Protocol version 2.0 used?
Action
Perform troubleshooting for when the D LINK LED turns off or is
flashing. ( Page 124 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 that "Network Configuration Settings" of the master station
and the actual system configuration match.
Correct the switching hub and the switching hub settings. For the
setting method, refer to the manual for the switching hub used.
• When using a TSN switching 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 201 Communication cycle intervals) For the
switching hub delay time of the switching hub used, contact the
manufacturer.
Set "System Reservation Time" to 200 s.
Change the IP filter setting parameter to allow communication for the
IP address of another station.
Disconnect the CC-Link IE TSN Class A devices.
Check the connected device and disconnect the general-purpose
switching hub or replace it with a TSN switching hub.
Check the connected devices and reduce the number of CC-Link IE
TSN Class B devices and TSN switching hubs to eight or less in total 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 switching hub in star topology.
Alternatively, connect CC-Link IE TSN Class B devices to the TSN
switching hub in star topology.
Check the connected device and connect the master station to CC-Link
IE TSN Class B devices in line topology instead of using a general-
purpose switching hub.
Check the connected device and connect the master station with CC-
Link IE TSN Class B devices via a TSN switching hub.
Check the connected device and connect the Ethernet device at the
end of the network.
Use the NZ2EHG-T8(N) or DT135TX.
Change "CC-Link IE TSN Class Setting" under "Network Configuration
Setting" or "CC-Link IE TSN Class Setting" on the device station side
so that the "CC-Link IE TSN Class Setting" for each station match.
• Update the firmware of the master station to a version supporting the
CC-Link IE TSN Protocol version 2.0.
• Replace the master station with a master station supporting the CC-
Link IE TSN Protocol version 2.0.
