STATIONS
12.1.4 Creating a program
Create the program for reading the remote input (RX), writing the remote output (RY),
reading the remote registers (RWr) and writing remote registers (RWw) from/to the
local station.
The following illustrates the relation between the I/O operations and the user program
when sending/receiving data between the master station and local station.
(The shaded areas indicate the devices that are actually used.)
