I/O STATIONS
10.4 Creating a Program
This section explains how the created program reads data from the remote input (RX)
and writes them to the remote output (RY) in communications with remote I/O stations.
The following illustrates the relation between the remote I/O stations’ I/O operations
and the user program when controlling the remote I/O stations. (The shaded areas
indicate the devices that are actually used.)

: When the remote net Ver.2 mode is selected, refer to the figure in Section 4.4.7(1).
When the remote net additional mode is selected, refer to the figure in Section 4.4.7(2).
User Program CC-Link Ver.2 Board
2) The remote input data (RX) of the CC-Link Ver.2
board are read out.
Arguments to be set:
Station No.=0xFF (own station)
Device type=0x1 (own station RX)
Device No. =0x0
3) Data are written to the remote output (RY) of the
CC-Link Ver.2 board.
Arguments to be set:
Station No.=0xFF (own station)
Device type=0x2 (own station RY)
Device No. =0x20
1) The input data (X) of the remote I/O station are
stored into the remote input (RX) on the CC-Link
Ver.2 board by the link scan.
4) The remote output data (RY) of the CC-Link Ver.2
board are output to the remote I/O station.
