Determine the number of I/O points for the I/O Unit –MODEL A using
the following.
Output points
Sum of the actual output Occupied output points
points in a group
0 to 32 32 points
40 to 64 64 points
72 to 128 128 points
136 to 256 256 points
(Note) Count AOA05E as 8 points and AOA12F as 16 points.
Input points
Sum of the actual input Occupied input points
points in a group
0 to 32 32 points
40 to 64 64 points
72 to 128 128 points
136 to 256 256 points
As a result of the calculation above, when the number of input points is
smaller 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. . . . . . . . . . . . . . . . . . . . . . . .
AOA12F 2. . . . . . . . . . . . . . . . . . . . . . . .
AID32A 5. . . . . . . . . . . . . . . . . . . . . . . .
AIA16G 3. . . . . . . . . . . . . . . . . . . . . . . .
[Input points]
32×5+16×3 = 208 256 points
[Output points]
32×3+16×2 = 128 128 points
Example 2:
When the following modules are used in the group No. 2.
AOD16C 7. . . . . . . . . . . . . . . . . . . . . . . .
AOA05F 9. . . . . . . . . . . . . . . . . . . . . . . .
AID16A 4. . . . . . . . . . . . . . . . . . . . . . . .
AIA16G 3. . . . . . . . . . . . . . . . . . . . . . . .
[Input points]
16×4+16×3 = 112 128 points
[Output points]
16×7+8×9 = 184 256 points
In this case, as the number of input points is smaller than that of the
output points, the number of input points is assumedl to be equal to
that of the output points, in other words, 256 points.
