When the DATA LINK LED flashes
When the DATA LINK LED flashes in CC-Link IE TSN communication mode, check the following items.
Check item
Do the IP addresses match?
Does the station type match?
Is the FPGA module a reserved station?
Is the IP address of the FPGA module duplicated
with that of other station?
In the network configuration settings of the master
station, is the third or fourth octet of the IP address
duplicated by that of another station?
In the network configuration settings of the master
station, does each network address (the subnet
mask part of IP address) match that of the master
station?
Is another station in which a communication error
has occurred connected between the master
station and the FPGA module?
Has another station been remotely reset or
powered off?
Does a station on the network link up at the
desired communication speed?
Does the time synchronization source module
operate normally?
Is a time synchronization source module with a
higher priority newly connected to the network?
Does the master station connected to the network
operate normally?
Does the model name of the device station set in
the network configuration settings match the
model name of the actual device?
Is the event code of 00C81H registered for the
FPGA module with event history of the master
station?
Is the event code of 00C71H registered for the
FPGA module with event history of the master
station?
Are the IP address and subnet mask that can be
used for the FPGA module set in the network
configuration settings?
In the network configuration settings, are the
number of points set for RX and RY within the
range that can be used for the FPGA module?
In the network configuration settings, are the
number of points set for RWr and RWw within the
range that can be used for the FPGA module?
When the CC-Link IE TSN Network synchronous
communication function is used, is the set
synchronization cycle supported by the FPGA
module?

Action
Match the IP address of the FPGA module with the IP address that is set in the network configuration
settings of the master station.
Match the station type of the FPGA module with the station type that is set in the network configuration
settings of the master station.
Change the setting of reserved/error invalid station to other than the reserved station in the network
configuration settings of the master station.
At least two IP addresses are overlapped. Change the setting so that all IP addresses differ.
Set the IP addresses so that there is no duplication in the third and fourth octets of the IP addresses for all
the stations.
Set each IP address and subnet mask so that the network addresses of all the stations are the same.
The FPGA module cannot establish data link if there is no path available with which the FPGA module can
communicate with the master station without relaying data via a station with a communication error. If a
communication error has occurred in two or more stations, clear the error one by one, starting from the
station closest to the master station on the communication path.
Disconnection temporarily occurs due to remote reset or power-off of another station. Wait until
communication restarts.
Change the communication speed of the module or the switching hub to satisfy the communication speed.
• If an error occurs in the time synchronization source module, clear the error.
• When the time synchronization source module is reset or powered off, disconnection temporarily occurs
due to switching of time synchronization sources. Wait until communication restarts.
Disconnection temporarily occurs due to switching of time synchronization sources. Wait until
communication restarts.
If an error occurs in the master station, clear the error in the master station.
Change the network configuration settings so that the model name of the device station set in the network
configuration settings matches the model name of the actual device. Or, in the network configuration
settings, set the FPGA module as a "general-purpose remote station".
Change the CC-Link IE TSN Class in the network configuration settings so that the CC-Link IE TSN Class
set in the network configuration settings matches the CC-Link IE TSN Class of the FPGA module.
Alternatively, change the CC-Link IE TSN Class of the FPGA module.
The CC-Link IE TSN Network synchronous communication function may be set to "Synchronous" for
FPGA modules that have the CC-Link IE TSN Class setting set to CC-Link IE TSN Class A. In this case,
set the CC-Link IE TSN Network synchronous communication function to "Asynchronous" or set the CC-
Link IE TSN Class of the FPGA module to "CC-Link IE TSN Class B".
If the event code of 00C71H is still registered even after the above actions are taken, check the manual for
the master station in use and eliminate the cause.
Set the IP address and subnet mask that can be used for the FPGA module. ( Page 54 IP address/
station number setting switch setting)
Set 112 or less for the number of points each for RX and RY.
Set 144 or less for the number of points for each of RWr and RWw.
When using the CC-Link IE TSN Network synchronous communication function, set values in the range
that the FPGA module supports for the synchronous cycle. ( Page 353 CC-Link IE TSN Network
Synchronous Communication Function)
