FPGA Register Access Function
Reads from and writes to the FPGA register areas from the master station program.
There are two methods for reading from and writing to FPGA register areas. The appropriate method should be selected.
• Remote register method
• Method using remote buffer memory
Remote register method
This is used to periodically read from and write to the FPGA register areas (user circuit areas) from a program.
In CC-Link IE TSN communication mode, data is cyclically updated between the remote register areas and FPGA register
areas.
