Details of each item of detailed remote station information
1) Number of I/O points
The number of I/O points used in each station No. assigned to each buffer memory is stored
here.
The maximum number of points is 4 or 16 according to the number of points per station set
by the DIP switch.
For example, when a remote I/O unit having 16 I/O points is used in the 4-point mode, the
number of points per buffer memory is 4, and the I/O points of the remote I/O station are
assigned to four buffer memories.
In the case of composite I/O type remote unit, the larger amount between the number of
input points and the number of output points is stored.
