Action
If an error has occurred in the FPGA module, a network parameter may be set to a value that the FPGA
module cannot handle. If following errors have occurred, eliminate them in order from the top one. (
Page 443 TROUBLESHOOTING DURING FPGA DEVELOPMENT)
• Communication cycle setting error (1Gbps) (error code: D023H)
• Communication cycle setting error (100Mbps) (error code: D024H)
• Communication cycle setting error (CC-Link IE TSN Class A) (error code: D028H)
• Number of RX/RY points error (error code: D021H)
• RWr/RWw number of points error (error code: D022H)
• Synchronization cycle setting error (error code: D026H)
• RWw/RWr setting error (error code: D025H)
• Network synchronous communication setting error (error code: D020H)
• Network synchronous communication setting change disable error (error code: D027H)
• Communication setting error 2 (error code: D001H)
• Communication setting error 1 (error code: D000H)
When the CC-Link IE TSN Class of the FPGA module is CC-Link IE TSN Class A, set it to CC-Link IE
TSN Class B or connect with line topology, star topology, or a mixture of star topology and line topology.
If the CC-Link IE TSN Class setting of the FPGA module is set to CC-Link IE TSN Class A, take the
following action.
• Check the version of the master station, and if the version does not support CC-Link IE TSN Protocol
version 2.0, please update the master station to the corresponding version.
If the "Communication Period Setting" of the FPGA module is "Low-Speed", check CC-Link IE TSN Class
A (Low-Speed) multiple (buffer memory address: 1294304) of the master module buffer memory. If the
value of CC-Link IE TSN Class A (Low-Speed) multiple (buffer memory address: 1294304) is 6 or higher,
set the value of basic period  multiple  CC-Link IE TSN Class A (Low-Speed) multiple (buffer memory
address: 1294304) to 2.5ms or higher and 6.4 seconds or lower in the communication period interval
settings. For details, refer to the manual for the master station used.
Reduce the load on the network.
• If a broadcast storm has occurred, eliminate the cause.
• If an Ethernet device is connected, reduce the frequency of packets sent by the Ethernet device.
Action
Identify the cause of the error from the "CC-Link IE TSN/CC-Link IE Field Diagnostics" window, Latest
error code (RWr0), or the value of the FPGA Module Configuration Tool, and take corrective action.
Action
After downloading the configuration data, turn on the module power off and on. ( Page 300 FPGA
Download Function)
Use the FPGA development software to regenerate the configuration data, download the configuration
data, and then turn off and on the power to the module.
Action
Check if the wiring is correct. ( Page 54 INSTALLATION AND WIRING)
Refer to the check items in "When the FPGA RUN LED does not turn on" to enable FPGA control. (
Page 434 When the FPGA RUN LED does not turn on)
Check if the settings match the input/output specifications. ( Page 188 Standard Circuit)
Operate function setting switch 6 so that the terminal number display LED of the terminal block turns on.
Depending on the input/output pulse frequency, the LED may not turn on or the LED brightness may
decrease, but this does not affect the input/output operation. To check whether pulse input/output is
performed normally, use a pulse input/output device or other similar device to check that pulses can be
counted normally.
