Mitsubishi Electric MELSEC iQ-R Series User Manual page 30

When writing data to the area in the link refresh range, directly access the link device and write the same data
in the device of the CPU module.
• Bad example (Only direct access to the link refresh target)
Link refresh overwrites the value.
• Good example (In addition to direct access, writing the same data to the device of the CPU module)
The value written by direct access is reflected.
