negative, set the option to on in the

meter menu, see section 6 menu programming

interface for details. 2. When the two current inputs are input by the

Hall current sensor, the power supply of the

second Hall current sensor cannot be used

with the built-in power supply of the meter, and the power module needs to be externally

connected. 3. When the current is input by the shunt, the

voltage value measured by the four-wire

method has an error of about one thousandth. 4. It is recommended to use a 0.75mm2 or

1mm2 shielded twisted pair for the current

signal line, and the shield layer needs to be

connected to the ground.

仪表开关量输出采用继电器输出，有两种控制

方式：1、报警方式（“SEL”选择不为零）；2、总线

控制方式（“SEL”选择为“0. do”,此时“dLy”设

置为 0 为电平输出方式，设置非零为脉冲方式动作

后延时设置的时间自动断开）

“SEL”中设置 DO 输出类型，“0. do”表示为

通信控制（此时如果 DLY 设置为 0 输出为电平方式，

否则为脉冲方式，如果 DLY 设置为 2，吸合后 0.02

秒自动断开），其他为报警控制（见下表）

“dLy”为报警延时（报警用时推荐不设置为

0 防止干扰误动。）

“bAnd”为不动作带设置

The switch output of the meter adopts relay

output. There are two control modes: 1. Alarm mode

("SEL" selection is not zero); 2. Bus control mode

("SEL" is selected as "0. do". When “dLy” is set to 0, it is the level output mode. Setting non-zero as the

pulse mode will automatically disconnect the delay

setting time. “SEL” sets the DO output type. “0. do” means

communication control. (If DLY is set to 0, the output

is in level mode , otherwise it is in pulse mode. If

DLY is set to 2, automatic shutdown will take 0.02

seconds after pull in. Open), same as alarm control

(see the following table) "dLy" is the alarm delay time (it is not

recommended to set to 0 during the alarm to prevent

interference error.) "BAnd" is set for the non action band

第一路继电器输出

First relay output

由通信控制的 DO 输出模式，此时“dLy”为 0 则为电平控制。设置其他

7.1 概述 Overview

DJSF1352-RN 仪表采用 Modbus-RTU 协议：

“9600，8，n，1”，其中 38400 为默认波特率，可

通过编程修改为 1200、2400、4800、9600 等，；8

表示有 8 个数据位；n 表示无奇偶校验位；1 表示

有 1 个停止位。

The DJSF1352-RN meter uses the Modbus-RTU

protocol: “9600, 8, n, 1”, where 38400 is the default

baud rate, which can be programmed to change to

1200, 2400, 4800, 9600, etc.; 8 means there are 8 data

bits ;n indicates no parity; 1 indicates 1 stop bit.错误检测：CRC16（循环冗余校验） Error detection: CRC16 (Cyclic Redundancy

DJSF1352-RN meter adopts DLT645 protocol, supports 07, 97 version. The meter number defaults to

12 digits after barcode. See menu settings for

details.The protocol supports reading of voltage, current, power, forward and reverse direction and

combined energy and reading of multi-rate energy. At

the same time, the version 07 protocol also supports

programming records, reading of 10 events of time

setting, and 12 months of multi-rate energy and

demand, 3 times data instantaneous freezing and 12

times frozen data query.注意：当仪表选配双路直流，第二路直流测量

数据读取时，通讯地址自动在原来地址上加 1。

（modbus 设备地址加 1,645 表号自增 1，合计占 2

个号，相当于 2 个表）。

Note: When the meter is equipped with double

DC input channels and the measurement data of

second DC channel is read, the communication

address is automatically added 1 to the original

address.(The modbus device address plus 1,645

number is incremented by 1, and it occupies 2

numbers in total, equivalent to 2 meters). 7.2 DLT645 规约 DLT645 protocol

帧的“信封”（数据头），读取数据，如果没有错误，

就执行数据所请求的任务，然后，它将自己生成的

数据加入到取得的“信封”中，把数据帧返回给发

送者。返回的响应数据中包含了以下内容：终端从

error, executes the task requested by the data, then it

will add its own data to the obtained "envelope" and

return the data frame to the sender. The returned

response data includes the following contents: the

terminal slave address(Address), the executed

command(Function), the requested data generated by

executing command(Data), and a check code(Check). There will be no successful response to any error, or

an error indication frame is returned. 7.3.1 数据帧 Data frame format

8-Bits 8-Bits N×8-Bits 16-Bits

7.3.2 地址(Address)域 Address domain

地址域在帧首，由一个字节（8-Bits，8 位二进

制码）组成，十进制为 0～255，在我们的系统中只

使用 1～247，其它地址保留。这些位标明了用户指

定的终端设备的地址，该设备将接收来自与之相连

的主机数据。同一总线上每个终端设备的地址必须

是唯一的，只有被寻址到的终端才会响应包含了该

地址的查询。当终端发送回一个响应，响应中的从

机地址数据便告诉了主机哪台终端正与之进行通

信。

The address domain is at the beginning of the

frame and consists of one byte (8-bits, 8-bit binary

code). The decimal value is 0 to 255. Only 1 to 247

are used in our system, and other addresses are

reserved. These bits indicate the address of the

user-specified terminal device that will receive data

from the host to which it is connected. The address of

each terminal device must be unique. Only the

terminal to which it is addressed will respond to a

query containing the address. When the terminal sends

back a response, the data of the slave address in the

response tells the host which terminal is

communicating with it. 7.3.3 功能(Function)域 Function domain

功能域代码告诉了被寻址到的终端执行何种

功能。下表列出了该系列仪表用到的功能码，以及

它们的意义和功能。

addressed terminal. The following table lists the

7.3.4 数据（Data）域 Data domain

数据域包含了终端执行特定功能所需的数据

或终端响应查询时采集到的数据。这些数据可能是

数值、参量地址或者设置值。

The data domain contains the data required for

the terminal to perform a specific function or the data

collected when the terminal responds to a query. These data may be numeric values, parameter

addresses, or setting values.例如：功能域告诉终端读取一个寄存器，数据

域则需要指明从哪个寄存器开始及读取多少个数

据，内嵌的地址和数据依照类型和从机之间的不同

而内容有所不同。

For example, the function domain tells the

terminal to read a register, and the data domain needs

to specify which register to start and how many data

to read. The embedded address and data differ

according to the type and the slave. 7.3.5 错误校验（Check）域 Error check domain

该域采用 CRC16 循环冗余校验，允许主机和终

端检查传输过程中的错误。有时由于电噪声和其它

干扰，一组数据从一个设备传输到另一个设备时，

在线路上可能会发生一些改变，错误校验能够保证

主机或从机不去响应那些发生改变的数据，这就提

高了系统的安全性、可靠性和效率。

This domain uses a CRC16 cyclic redundancy

check to allow hosts and terminals to check for errors

during transmission. Sometimes due to electrical noise

and other interference, when a group of data is

transferred from one device to another, some changes

may occur on the line. Error checking can ensure that

the master or slave does not respond to those changed

data. This improves the security, reliability, and

efficiency of system. 7.3.6 错误校验的方法Error check method

错误校验（CRC）域占用两个字节，包含了一

个 16 位的二进制值。CRC 值由传输设备计算出来，

然后附加到数据帧上，接收设备在接受数据时重新

计算 CRC 值，然后与接收到的 CRC 域中的值进行

比较，如果这两个值不相等，就发生了错误。

The error check (CRC) domain occupies two

bytes and contains a 16-bit binary value. The CRC

value is calculated by the transmitting device and then

appended to the data frame. The receiving device

recalculates the CRC value when receiving the data, and then compares it with the value in the received

CRC domain. If the two values are not equal, it occurs

error. CRC 运算时，首先将一个 16 位的寄存器预置

为全 1，然后连续把数据帧中的每个字节中的 8

位与该寄存器的当前值进行运算，仅仅每个字

节的 8 个数据位参与生成 CRC，起始位和停止位以

及可能使用的奇偶位都不影响 CRC。在生成 CRC

时，每个字节的 8 位与寄存器中的内容进行异或，

然后将结果向低位移位，高位则用“0”补充，最

低位（LSB）移出并检测，如果是 1，该寄存器就与

一个预设的固定值（0A001H）进行一次异或运算，

如果最低位为 0，不作任何处理。

In the CRC operation, a 16-bit register is first

preset to all ones, and then 8 bits in each byte in the

data frame are successively operated on with the

current value of the register, only 8 data bits per byte

participate in generating a CRC, and neither the start

and stop bits nor the parity bits that may be used affect

the CRC. When the CRC is generated, the 8-bit of

each byte is XORed with the contents of the register, and then the result is shifted to the low-order bit. The

high-order bit is complemented with "0" and the LSB

is shifted out and detected. If it is 1, This register is

XORed with a preset fixed value (0A001H). If the

least significant bit is 0, nothing is done.

CRC 生成流程：

1 预置一个 16 位寄存器为 0FFFFH（全 1），

称之为 CRC 寄存器。

2 把数据帧中的第一个字节的 8 位与 CRC 寄

存器中的低字节进行异或运算，结果存回 CRC 寄存

器。

3 将 CRC 寄存器向右移一位，最高位填 0，最

低位移出并检测。

4 如果最低位移出为 0：重复第 3 步（下一次

移位）；如果最低位移出为 1：将 CRC 寄存器与一

个预设固定值（0A001H）进行异或运算。

5 重复第 3 步和第 4 步直到 8 次移位。这样

就处理完了一个完整的 8 位。

6 重复第 2 步到第 5 步来处理下一个 8 位，

直到所有的字节处理结束。

7 最终 CRC 寄存器的值就是 CRC 的值。

此外还有一种利用查表计算 CRC 的方法，它的

主要特点是计算速度快，但是表格需要较大的存储

空间，该方法此处不再赘述，请查阅相关资料。

CRC generation process:

1 Preset a 16-bit register to 0FFFFH (all 1s) and

call it CRC register. 2 XOR the 8 bits of the first byte in the data

frame with the low byte in the CRC register

and store the result back in the CRC register. 3 Move the CRC register one bit to the right, fill “0” in the highest bit, and move the lowest bit

out and detect it. 4 If the shifted out minimum bit is 0: Repeat step

3 (next shift); if the shifted out minimum bit is

1: XOR the CRC register with a preset fixed

value (0A001H). 5 Repeat step 3 and 4 until 8 shifts to complete a

complete 8-bit processing. 6 Repeat step 2 to 5 to process the next 8 bits

until processing of all byte ends. 7 The final CRC register value is the CRC value. In addition, there is a method for calculating

CRC by using a look-up table. Its main feature

is that the calculation speed is fast, but the

table needs a large storage space. This method

is not described here any more. Please refer to
