Accordingly, the I/O number of the individual FP0 I/O Link Unit
identified by the FP3/FP10SH is determined by the base word
number of the Master Unit and the station number of the FP0
I/O Link Unit.
In the remote I/O map, the Input numbers are allocated first.
For example, in the drawing shown above, when the FP0 I/O
Link Unit of station no. 1 is connected to a Master Unit whose
base word number is 64, the input number from the
FP3/FP10SH to the FP0 I/O Link Unit is WX64 and 65 (X640 to
65F), and the output number is WY66 and 67 (Y660 to 67F).
When the FP0 I/O Link Unit of station no. 2 is connected in the
same manner, the input number from FP3/FP10SH to the FP0
I/O Link Unit is WX68 and 69 (X680 to 69F), and the output
number is WY70 and 71 (Y700 to 71F).
The relationship between the input/output of the FP3/FP10SH
and that of the FP0 from the illustration above is shown below:

WY2,3 (Y20 to 3F)

WY2,3 (Y20 to 3F)
WX2,3 (X20 to 3F)
For example, when the Y20 in the FP0 at station no. 1 turns
ON, the X640 in the FP3/FP10SH turns ON. When the Y660 in
the FP3/FP10SH turns ON, the X20 in the FP0 at station no. 1
turns ON. Similarly, when the Y20 in the FP0 at station no. 2
turns ON, the X680 in the FP3/FP10SH turns ON. When the
Y700 in the FP3/FP10SH turns ON, the X20 in the FP0 at
station no. 2 turns ON. In this way, the FP0 I/O Link Unit can
exchange I/O information between the FP3/FP10SH and the
FP0.
