The following provides an example of how the link device (W) on the CPU
module side is sent to an intelligent function module.
1) Data is sent to the remote master station W0.
2) W0 data is stored in the master module refresh data storage area (LW)
by link refresh.
3) The W0 data in the refresh data storage area (LW) is stored as W0 in
the link data storage area (LW) according to the common parameters.
4) The W0 data in the link data storage area (LW) is stored in the link
data storage area (LW) for the remote I/O module by link scan.
5) The W0 data in link data storage area (LW) is stored in refresh data
storage area (LW).
6) The W0 data is written to the remote I/O station intelligent function
