● Sampling Values of Devices when Value of Device Changes
When sampling values of devices (D100 to D102), when a bit device configured as the sampling condition switches
from 0 to 1 and the data storage amount in the data storage area is set to 3, the Touch samples Data Log data as
follows.
1 When data sampling starts and the bit device configured as the sampling condition switches from 0 to 1, the Touch
stores the values for devices D100 to D102.
2 When the sampling condition device switches from 0 to 1 the second time, the Touch stores the values for devices
D100 to D102.
3 When the sampling condition device switches from 0 to 1 the third time, the Touch stores the values for devices D100
to D102.
4 When the sampling condition device switches from 0 to 1 the fourth time, the Touch stores the values for devices
D100 to D102.
Since the data storage amount in the data storage area is set to 3, the oldest data is deleted in order to make room
for the newest data.
