Note: 1. Read-write property: "RO" is read-only, parameter is read with 0X03H command; "R/W" is readable and writable, and system
parameter is written with 0X10H command. Do not write data to unlisted or unwritable Address.

For Int32 type data, the high bits are in the front and the low bits are in the back
2. Correspondence between communication value and actual value
It is agreed that Val_t is the communication readout value and Val_s is the actual value.
2.1 Voltage, Current, Power Factor, Frequency, Unbalance (Secondary)
The series of measured values are read with 03 command of the Modbus-RTU communication protocol. Each item occupies 1
word. The correspondence between the communication value and the actual secondary measurement value is shown in the following
table:
For example: To read phase A voltage Uan, the data can be read at address 243 in Int16eger reading mode by MODSCAN, the
communication read-out value Val_t is 2200,then Val_t = 2200*0.1=220V.
2.2 Voltage, Current, Power Factor, Frequency, Unbalance (Primary)
The series of measured values are read with 03 command of the Modbus-RTU communication protocol. The voltage and current
occupy 2 words, and the power factor, frequency, and unbalance occupy 1 byte. The correspondence between the communication value
and the actual secondary measurement value is shown in the following table:
