0xFE Read Data Log Read the contents of data log

9.3.2 Modbus Communication Protocols

(1) Modbus RTU mode is adopted with Modbus Master sending out the Request, in which the Function

Code uses 0x03 to request response from Slave to correspond to values in Modbus address. In

Response, Modbus Slave responds to the values of Modbus address in the Master request. The

packet format of IEEE754 is used for the address of ﬂoating point numbers that corresponds to the

Low Word High Word

High Byte Low Byte High Byte Low Byte

The packet formats for the address of integers that corresponds to the register values found in table 7.1

are shown in the example below.

Example:

For Modbus Master, such as PLC or data collector, it uses Modbus communication protocol to get a

reading for the value of currents from the primary current transformer (register address 0x000E) on the

power meter (Modbus Slave) (Slave address 0x1). The register value is 1000.

The packet format for Request sent out by Modbus Master (PLC or data collector) is as follows:

Master Request

0x01 0x03 0x00 0x0E 0x0 0x01 CRC

Slave Address Function Code

Start Address

(Hi)

Start Address

(Lo)

Number of Points (Hi)

Number of

Points (Lo)

The packet format for Response responded by Modbus Slave (power meter) is as follows:

Slave Response

0x01 0x03 0x4 03 E8 CRC

After receiving response from the power meter, Modbus Master acquires the value of currents from the primary-side current transformer (register address 0x000E), which is 1000.

Slave Address Function Code

Byte Count Data

Should Modbus Slave (power meter) receive an abnormal Request, the format of the abnormal packet responded is as follows. Refer to Chapter 9 for the abnormal codes.

Slave Response

0x01 0x83 0x1 CRC

9.3.3 User-deﬁned Communication Protocol for Data Log Reading

(1) Take an approach similar to Modbus RTU mode. The Modbus Master sends out Request using

Function Code 0x03, which requests the Slave to response the value of the corresponding Modbus

address. The Modbus Slave will provide the value through Response.

Example:

If a Modbus Master (such as PLC or data collector) uses a user-dened communication protocol to read

the data log, the address is 0x0800. The packet format of Request sent by Modbus Master is as follows

(Similar as Modbus RTU, but the Number of Points can only be 1):

Master Request

0x01 0xFE 0x08 0x00 0x00 0x01 CRC

Slave Address Function Code

Start Address

(Hi)

Start Address

(Lo)

Numbers of

Points (Hi)

Numbers of

Points (Lo)

The packet format of Response responded by Modbus Slave (Power Meter) is as follows: (Similar to

Modbus RTU before Byte Count. The only difference is that the data is a sting of Log data, and the

sequence is as listed as follow. The total size is 66 bytes.)

Notes on selecting a current transformer

1. For the current transformer, the model with a closer maximal current on the primary side should be selected according to the maximal current actually input. For example: When the maximal current input is 700 A, DCT-S261C can be selected.

2. Wire over-length on the secondary side of the current transformer causes decrease in accuracy.
