Sampling Values of Device Addresses when a Value of Device Address Changes
●
If sample values of device addresses (D100 to D102), when the bit device or the bit number of the word device
configured as the Condition of Writing to Data Storage Area 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. (When Sampling Method is While
satisfying the condition of writing to data storage area)
0
1
When data sampling starts and the value of device address configured as the Condition of Writing to Data Storage
Area switches from 0 to 1,the MICRO/I stores the values for device addresses D100 to D102.
2
When the value of device address configured as the Condition of Writing to Data Storage Area switches from 0 to 1
the second time, the MICRO/I stores the values for device addresses D100 to D102.
3
When the value of device address configured as the Condition of Writing to Data Storage Area switches from 0 to 1
the third time, the MICRO/I stores the values for device addresses D100 to D102.

When the value of device address configured as the Condition of Writing to Data Storage Area switches from 0 to 1
the fourth time, the MICRO/I stores the values for device addresses 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.
