1.2 Sampling Values of Device Addresses
The MICRO/I samples values of target device addresses at a regular interval or when a value of device address
changes.
Sampling Value of Device Addresses at a Regular Interval
●
When sampling values of device addresses (D100 to D102) at a 5 minute interval (Time: 300 seconds) with the data
storage amount in the data storage area is set to 3, the MICRO/I samples Data Log data as follows.
12 : 05 : 00
12 : 10 : 00
12 : 15 : 00
1
5 minutes after data sampling starts, the MICRO/I stores the values for device addresses D100 to D102.
2
10 minutes after data sampling starts, the MICRO/I stores the values for device addresses D100 to D102.
3
15 minutes after data sampling starts, the MICRO/I stores the values for device addresses D100 to D102.

20 minutes after data sampling starts, 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.
