Setting the Number of
AD Conversion Points
Note
420
Normally, when using a four-point Input Unit, the values for the four inputs are
converted in sequence. The setting can be changed, however, so that unused
inputs are not converted. By reducing the number of conversion points, the
conversion cycle speed is increased. For details on conversion cycle time,
refer to 6-4-3 Calculating the Conversion Cycle.
Conversion points
4 points (default)
3 points
2 points
1 point
Four points of input analog data are used regardless of the setting of the num-
ber of AD conversion points.
