Logging Interval: the time interval between two records. the unit is minute. The range is
0-1440. (when it is set as 0, logging will be disabled)
2. Parameter Address
Register: 1302H-1376H
Size: One parameter uses one, two or three Modbus register addresses, in total there are
117 addresses.
Modbus register address list, you can set the parameters that are recorded in the record
set the trend,
because some parameters, such as power and electricity, etc., takes up
two Modbus address, to record these parameters need to use two Modbus address to
characterize. Some parameter take up 3 Modbus address such as maximum demand
happening time.
For example: Register 2000H and 2001H is set in the trend recorded in the register list,
the trends recorded in these registers record access frequency value. Frequency Modbus
addresses is 2000H and 2001H.
Note:
when 117 registers are all fully assigned, be sure that no extra parameters will be
assigned. For example, all parameter registers are energy, when all 117 registers are full, it
leads to that the last energy only uses one Modbus address. The last value will be incorrect
because every energy uses two Modbus addresses.
•Unused register should be set as 0000H or FFFFH.
• Each logging size is decided by the above register number
3. Register property:
Register: 1377H-13B1H
Size: one register uses one byte, in total there are 117 descriptors.(59 register addresses)
The descriptor indicates how many register number one parameter uses. It can be set as 1
