1) Sum the numbers of the occupied I/O points in Table 1 for all
slaves connected with a single I/O Link. The sum must satisfy the
following restriction :
Number of input points ≦ 1024 (per one I/O Link)
Number of output points ≦ 1024 (per one I/O Link)
2) Number of the occupied I/O points per one group must satisfy the
following restriction :
Number of input points ≦ 256 (per one group)
Number of output points ≦ 256 (per one group)
3) Determine the number of I/O points for the I/O Unit-A using the
following.
[Output points]
Sum of the actual output Occupied output
points in a group points
0 to 32 Þ 32 points
40 to 64 Þ 64 points
72 to 128 Þ 128 points
136 to 256 Þ 256 points
NOTE
Count AOA05E as 8 points AOA12F as 16 points.
[Input points]
Sum of the actual output Occupied output
points in a group points
0 to 32 Þ 32 points
40 to 64 Þ 64 points
72 to 128 Þ 128 points
136 to 256 Þ 256 points
However, as result of the calculation above, when the
number of input points is not larger than that of the output
points in a single group, the number of input points is
assumed to be equal to that of the output points.
Example 1 : When the following modules are used in the group
No. 0.
AOD32C 3 AID32A 5
AOA12F 2 AIA16G 3
[Output points]
32 × 3 + 16 × 2 = 128 Þ 128 points
[Input points]
32 × 5 + 16 × 3 = 208 Þ 256 points
Example 2: When the following modules are used in the group
No.2
AOD16C 7 AID16C 4
AOA05E 9 AIA16G 3
[Output points]
16 ×7 + 8 ×9 = 184 Þ 256 points
[Input points]
16 ×4 + 16×3 = 112 Þ 128 points
