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"
In the case of line topology, do the communication speed settings of each station
match?
Is there any reason why cyclic transmission cannot be performed on the device
station side?
Is the event code 00C44 registered in the event history?
Is the minimum value for communication cycle interval set to the "Communication
Period Interval Setting" in "Communication Period Setting" under "Basic Settings"
of the module parameter?
Is the minimum value for cyclic transmission time set to "Cyclic Transmission Time"
in "Communication Period Setting" under "Basic Settings" of the module
parameter?
In multicast mode, has an external device sent a frame to a station before data link
establishment of all stations?
When the communication speed setting of the master station is set to 1 Gbps, is the
total cyclic data size of all device stations on the 100 Mbps device side at the
boundary between CC-Link IE TSN Class B 1 Gbps devices other than the master
station and CC-Link IE TSN Class B 100 Mbps devices exceeding 2K bytes?
■For the version of Add-on baseSystem is "1.22" or earlier
When the communication speed of the master station and the device station of the
CC-Link IE TSN Class A is 1 Gbps, is the "Communication Period Setting" of the
device station of the CC-Link IE TSN Class A set to "Basic Period" or "Normal-
Speed"?

■When connected devices are protocol version
2.0
If "CC-Link IE TSN Class Setting" of the
general CC-Link IE TSN module added to the
station list in the "CC-Link IE TSN
Configuration" window is CC-Link IE TSN Class
A, are the minimum values of the
communication cycle interval and the cyclic
transmission time set to "Communication
Period Interval Setting" and "Cyclic
Transmission Time" in "Communication Period
Setting" under "Basic Settings"?
Is the event code 00C72 registered in the event
history?
■When the version of Add-on baseSystem is
"1.20 to 1.22"
Is a CC-Link IE TSN Class A device that
supports the CANopen profile with the protocol
version 2.0 connected?
Action
Select the actual device to be used from "Module List" in the "CC-Link IE
TSN Configuration" window and add it to the list of stations, or refer to
the manual for the device to be connected to check the maximum
response time for the time managed polling method and set the
calculated values to "Communication Period Interval Setting" and "Cyclic
Transmission Time".
• Update the engineering tool to the latest version.
• Update the device station firmware with IP address displayed in the
detailed information of the event history to the latest version.
Update the master station firmware to Add-on baseSystem version
"1.24" or later.
Check and correct the settings on the communication speed of each
station. For the setting method of the communication speed, refer to the
manual for each device.
• Check if an error has occurred on the device station.
• Check if the device station settings and parameters are correct.
• Refer to the manual of the device station for troubleshooting.
Match the communication speed of the master station to the
communication speed of the station for which the device station
parameter automatic setting is to be configured.
Set a value obtained by adding the largest out of the following to the
cyclic transmission time.
• 10% of the calculated minimum cyclic transmission time
• When the communication speed of the master station is set to 1 Gbps:
Number of device stations  2 s
• When the communication speed of the master station is set to 100
Mbps: Number of device stations  20 s
Ensure that the external device will not send a frame before data link
establishment of all stations, then reset the master station.
• Restrict the number of stations to be connected so that the total cyclic
data size of 100 Mbps devices does not exceed 2K bytes.
• Connect 100 Mbps devices to the master station.
• Update the Motion module to Add-on baseSystem version "1.24" or
later.
• Set the value set for "Communication Period Interval Setting" and
"Cyclic Transmission Time" in "Communication Period Setting" under
"Basic Settings" to greater than or equal to the calculation value of the
calculation formula. (Page 275 Communication cycle interval)
