2) The input status of a remote I/O station is stored automatically (for each
link scan) in the master station's "remote input RX" buffer memory.
3) The input status stored in the "remote input RX" buffer memory is
stored in the CPU device set with the automatic refresh parameters.

4) The on/off data of the CPU device set with the automatic refresh
parameters is stored in the "remote output RY" buffer memory.
5) The output status stored in the "remote output RY" buffer memory is
output automatically (for each link scan) to remote I/O stations.

• When setting the automatic refresh parameters, be sure to specify "Y" for the
remote output RY refresh device. If any value other than "Y" (e.g. M or L) is
specified when the CPU stops, the status of the device before the stop is retained
as is. For the method to stop a data link, see Section 4.4.10.
