For example, log 1 uses 3 sectors, each sector saves 448 records, in total there will be 1344
records. When the user retrieves the data when 1340 records are used, the first sector of log
1 will be erased without being retrieved.
Data Retrieve Example
• The example is based on log 1.
• The logging content is Channel 1 Active Power, Channel 2 Active Power and Channel
3 Active Power (12 bytes), the logging interval is 1 minute, sector number is 10, register
number is 6, using log 1.
• The Offset is 0.
• There are no new records logged while retrieving.
a)Setup Log 1:
1. Set Tenant 1 Power, Tenant 2 Power, Tenant 3 Power into this log. Since each parameter
uses two Modbus registers, set 0x2102, 0x2103, 0x210e, 0x210f, 0x211a, 0x211b to 0x1302,
0x1303, 0x1304, 0x1305, 0x1306 and 0x1307.The descriptor is 2, so at the same time set
0x0202, 0x0200 to 0x1377, 0x1378
2. The register number is 6, it uses 10 sectors. So set 0x060A to 0x1300
3. The logging interval is 1 minute, set 0x0001 to 0x1301.
4. Log 1, set 0 to 0x13b9, the default is the log 1
b)Data Log Retrieve
The following describes how to retrieve from the earliest record to the latest record.
1. Calculate the max record number a window holds. The max record number = 246 /
Record Size. In this example, 246 / 24 = 10.
