(8) Writing of remote output (RY)
(1) Create a program that instructs CC-Link refreshing and then starts the data link

(2) Create the following program, and read RXn0 to RX(n+1)F into X100 to X11F.
POINT
When using QCPU (Q mode) or QnACPU, setting automatic refresh parameters
refreshes the contents of the remote input (RX) and remote output (RY)
automatically. Thus, the above program is not required.
