CC-Link IE TSN Network Synchronous
Communication Function
Reads and writes to the FPGA at the synchronous cycle of a master station that supports the CC-Link IE TSN network
synchronous communication function.
This enables an A/D converter module to operate at the same timing as other remote stations on the same network.
Applicable version
When using the CC-Link IE TSN network synchronous communication function, check the version of the master station.
User's manual for the master station used
Operation
Reads and writes to the register areas of the FPGA standard circuit and user circuit for each synchronization cycle of the
master station. The value read from the FPGA is sent to the master station at the next synchronization cycle.
Also, the value to be written to the FPGA register received from the master station is written to the FPGA at the timing of the
next synchronization cycle.
