3. Number of I/O points (b4 to b0)
The number of I/O points used in the BFM dependent station number is stored here.
The maximum number of points is 4 or 16 in accordance with the number of points per station set by the DIP
switch for operation setting.
When a remote I/O unit with 16 I/O points is used in 4-point mode, the number of points per buffer memory is
4, and the I/O points of the remote I/O unit are assigned to four buffer memories.
In the case of a composite I/O unit, the larger quantity between the number of input points and the number of
output points is stored here.
In the case of a remote device station, 16 points are stored here.
4. Input flag (b8) and output flag (b9)
The type of the corresponding remote module (input unit, output unit, composite I/O unit or remote device
station) is stored here.

5. RD station flag (b10)
When the station is a RD station, "1 (ON)" is stored.
When one unit occupies two or more stations, this bit is set to ON in the corresponding stations.
