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.)
