Like the sliding block, a calculation period is set first, and the increment is also one
minute. However, only one demand is calculated in the whole period. So the interval of the
demand update is the calculation of the cycle time. The following example is a figure for
15-minute block interval:
4.2.2.2 Fix Block
4.3 Block transfer function
This function is mainly about allowing the user to gather alll the parameter values and
read them at one time.
Fill in the address of the parameter with 0x5000~0x504F in sequence, and then you can
read the value of the corresponding parameter from the address of 0x5100~0x514F.
Please refer to the setting range marked in the communication address table for the
address range that can be set.
For example:
When 0x5000 is written to 0x1001 (high byte address of V1 voltage of main loop A),
0x5001 is written to 0x1002 (low byte address of V1 voltage of main loop A), the value
obtained by reading 0x5100 and 0x5101 is the V1 voltage value of main loop A, and so on.
4.4 Data Logging function
In order to help users understand the history of the meter, the meter provides data
logging function.
Record a set of data at regular intervals. Meter is equipped with data storage capacity of
2MB for data recording. The meter has a real-time clock and each data log will be recorded.
