3.1.4.2.2 Remote I/O Area
The remote I/O of a remote device station is divided into the user-defined area
and system area as shown below.
In the table below, "m" denotes the register number assigned to each remote
station, and "n" denotes the last register number for the number of occupied
points (n = (2 * No. of occupied stations) - 1).
