4.3 Advanced Setups
4.3.1 Auto Metering
Energy 1: Enable or disable auto metering Group 1. The Default setting is disabled. Corresponding
Modbus address is 0x502.
Auto Day 1: Set the date to conclude the monthly accumulated energy value; options are 1–31; 0 is
default. Corresponding Modbus address is 0x504
Energy 2: Enable or disable auto metering Group 2. The Default is disabled. Corresponding Modbus
address is 0x507.
Auto Day 2: Set the date to conclude the monthly accumulated energy value; options are 1–31; 0 is
default. Corresponding Modbus address is 0x509.
4.3.2 Data Log
Interval: Parameter intervals; the first two digits represent minute(s), the last two digits represent
second(s). The minimum interval is 0 minute 5 seconds; the maximum is 60 minutes. If 0 minute 0
second is set for the Interval, it means the function is disabled (default). Corresponding Modbus address
is 0x501.
Example: To record the Voltage L-N and Current values, write 1 (the code for Voltage L-N) into the
Modbus address 0x55B with function code 0x06 (single write) or 0x10 (multi-write) first, and then write 2
(the code for Current) into the Modbus address 0x55C with function code 0x06 (single write) or 0x10
(multi-write). Refer to section 5.1 for more information on the codes and Modbus addresses.
Note
(1) Before setting up Interval, make sure to first set the recording parameter codes, or only date and time are
recorded. You can set the Interval through a user interface (using the Set up Steps above), or through Modbus
Communication (the address is 0x501).
(2) The following table lists the various parameters you can select according to different Intervals.
