Sampling Values of Devices when a Value of Device Changes
If sample values of devices (D100 to D102), when a bit device or bit of the word 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 MICRO/I samples
Data Log data as follows.
1
When data sampling starts and the value of device configured as the sampling condition switches from 0 to 1, the
MICRO/I stores the values for devices D100 to D102.
2
When the value of device configured as the sampling condition switches from 0 to 1 the second time, the MICRO/I
stores the values for devices D100 to D102.
3
When the value of device configured as the sampling condition switches from 0 to 1 the third time, the MICRO/I
stores the values for devices D100 to D102.
4
When the value of device configured as the sampling condition switches from 0 to 1 the fourth time, the MICRO/I
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.
