When transient transmission cannot be performed
The following lists the actions to be taken if transient transmission cannot be performed with the target station, and the
engineering tool cannot perform monitoring.
Check item
Is the D LINK LED of the Motion module flashing or turned on?
Is the data link status of the target station normal?
Are the following data set correctly when a module FB or dedicated instruction is
executed?
• Target station CPU type
• Target network number
• Target station number
Is the network number duplicated on the network?
Are multiple link dedicated instructions with the same channel setting executed
simultaneously?
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 TROUBLESHOOTING

8.4 Troubleshooting by Symptom
Are CC-Link IE TSN Class A devices connected?
Is a general-purpose switching hub connected?
■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?
■For firmware version "1.002" or later
Is the event code 00C80 registered in the event history?
■For firmware version Is 'CC-Link IE TSN
"1.002" or later Protocol version 2.0
Is 'Protocol operating support status for each
status' (Un\91270) set to station' (SW01A0 to
"2" (A device is operating SW01A7) set to "0: Not
with the CC-Link IE TSN supported"?
Protocol version 2.0)?
Action
Perform troubleshooting to be performed when the D LINK LED turns
off. ( Page 124 When the D LINK LED turns off or is flashing)
In the CC-Link IE TSN/CC-Link IE Field diagnostics, identify the cause
of the error and take action. ( Page 129 Checking the Network
Status)
Correct the section where the module FB or dedicated instruction is
executed in the program.
Correct the parameter so that duplication does not occur among
network numbers.
• Set a different channel to each instruction.
• Shift the execution timing of the link dedicated instructions.
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.
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.
• Check 'CC-Link IE TSN Protocol version 2.0 support status for each
station' (SW01A0 to SW01A7), and update the firmware of the
device station that does not support the CC-Link IE TSN Protocol
version 2.0 to a version supporting the CC-Link IE TSN Protocol
version 2.0.
• Replace the device station with a device station supporting the CC-
Link IE TSN Protocol version 2.0.
• Update the firmware of the device station that does not support the
CC-Link IE TSN Protocol version 2.0 to a version supporting the CC-
Link IE TSN Protocol version 2.0.
• Replace the device station with a device station supporting the CC-
Link IE TSN Protocol version 2.0.
• Power on the device stations and devices in the communication
path, and then power on the master station.
