Analog Output Units Section 5-5
The following table shows the additional time required for each function
(unit: ms).
Calculation Example When using two points, and applying scaling to the first input, and the cumula-
tive counter to the second input, the maximum AD conversion cycle time can
be obtained by using the following formula.
Formula: 2.42 + 0.055 + 0.035 = 2.51 ms
