Comments:

1. The power factor has its sign adjusted to indicate the direction of the current.
2. Positive refers to forward current, negative refers to reverse current.
3. The power sum demand calculation is for import - export.
4. Total active energy / reactive energy equals to Import + export.

For example:

1. Read Input Register — Read "Phase 1 line to neutral volts"

Request: 01 04 00 00 00 02 71 CB

01 = Meter address

04 = Function code

00 = High byte of registers starting address

00 = Low byte of registers starting address

00 = High byte of registers number

02 = Low byte of registers number

71 = CRC Low

CB = CRC High

Response: 01 04 04 43 66 33 34 1B 38

01 = Meter address

04 = Function code

04= Byte count

43 = Data, (High Word, High Byte)

66 = Data, (High Word, Low Byte)

33 = Data, (Low Word, High Byte)

34 = Data, (Low Word, Low Byte)

1B = CRC Low

38 = CRC High

Note: 43 66 33 34(Hex) = 230.2 (Floating point)

2. Write Holding Registers — Write "System type = 4"

Request: 01 10 00 0A 00 02 04 40 80 00 00 67 F8

01 = Meter address

10 = Function code

00 = High byte of registers starting address

0A = Low byte of registers starting address

00 = High byte of registers number

02 = Low byte of registers number

04 = Byte Count

40 = Data, (High Word, High Byte)

80 = Data, (High Word, Low Byte)

00 = Data, (Low Word, High Byte)

00 = Data, (Low Word, Low Byte)

67 = CRC Low

F8 = CRC High

Note: 40 80 00 00 (Hex) = 4 (Floating point)

Response: 01 10 00 0A 00 02 61 CA

01 = Meter address

10 = Function code

00 = High byte of registers starting address

OA = Low byte of registers starting address

00 = High byte of registers number

02 = Low byte of registers number

61 = CRC Low

CA = CRC High

3. Read Input Status — Read "DI1\~4 status"

Request: 01 02 00 00 00 04 79 C9

01 = Meter address

02 = Function code

00 = High byte of registers starting address

00 = Low byte of registers starting address

00 = High byte of read DI number

04 = Low byte of read DI number

79 = CRC Low

C9 = CRC High

Response: 01 02 01 03 E1 89

01 = Meter address

02 = Function code

01 = Byte Count

03 = Data, (DI status)

E1 = CRC Low

89 = CRC High

Note: Data=0 x 03 = 0000 0011 (Binary Value).

Bit 0 refers to the status of DI-1. The value is 1, which means DI-1 is on.

Bit 1 refers to the status of DI-2. The value is 1, which means DI-2 is on.

Bit 2 refers to the status of DI-3. The value is 0, which means DI-3 is off.

Bit 3 refers to the status of DI-4. The value is 0, which means DI-4 is off.
