1． 概述 Overview
外置开合式互感器的导轨式多功能电力仪表，适用于冶炼、钢铁、电焊、半导体等高能耗行业的节能改造工
程，也适用于分布式光伏并网柜的功率监测、电力需求侧管理等应用。具有无需拆一次母线、接线简单方便、施
工安全，为用户节约改造成本、提高效率等特点。它集成全部电力参数的测量(如单相或者三相的电流、电压、
有功功率、无功功率、视在功率、频率、功率因数)以及电能监测和考核管理。同时它具有多种外围接口功能可
供用户选择：带有RS485通讯接口，采用MODBUS-RTU协议可满足通讯联网管理的需要；带开关量输入和继电
器输出可实现断路器开关的“遥信”和“遥控”的功能，采用LCD显示界面，通过面板按键来实现参数设置和控制，
非常适合于实时电力监控系统。
The rail-type multifunction electrical instrument with external Rogowski coil and split-core current transformer is
applicable for the energy-saving reconstruction project in high energy consumption industries including the smelting,
iron and steel, welding and semi-conductor industry. It is also suitable for applications such as the power monitoring of
grid-connected cabinet for distributed photovoltaic power cabinet and energy demand management. It boasts of no need
of bus removal, easy connection and safe construction, saving reconstruction cost and raising efficiency for the user. It
integrates the measurements of all electric parameters (including single-phase or three-phase current, voltage, active
power, reactive power, apparent power, frequency and power factor ）and comprehensive energy monitoring and
examination management. Meanwhile, it also has various peripheral interfaces for the user to choose: the RS485
communication interface with MODBUS-RTU protocol can meet the need of online communication management; the
interfaces with switch input and relay output can realize the remote signalling and remote control of the circuit breaker
switch. It is very suitable for real-time power monitoring system with an LCD display and the panel buttons to realize the
setting and control of parameters.

7．通讯接线 Communication Connection
该仪表提供异步半双工 RS485 通讯接口，采用 MODBUS-RTU 协议，各种数据信息均可在通讯线路上传送。理
论上在一条线路上可以同时连接多达 128 个仪表，每个仪表均可设定其通讯地址（Addr），通讯速率（baud）也
可通过设置选择。
The instrument provides asynchronous half-duplex RS485 communication interface wich adopts MODBUS-RTU
protocol so all kinds of data can be transmitted on the communication line. Theoretically, one communication line can be
connected with up to 128 instruments, each of which can set a communication address (Addr) and communication rate
(baud) via setting.
通讯连接建议使用三芯屏蔽线分别接 A、B、COM2，屏蔽层接大地，COM2 禁止接大地，布线时应使通讯线远
离强电电缆或其他强电场环境。
For the communication connection, we recommend to use the three-core shielding wire .The core wires are
connected to A,B,COM2 respectively and the shielding layer is connected to the ground. COM2 is forbidden to have
ground connection. When laying the wires, the communication line shall be kept away from the strong current cable or
other strong electric field.
建议最末端仪表的 A、B 之间加匹配电阻，阻值范围为 120Ω～10kΩ。
It is recommended to add a matching resistor between A and B of the end instruments. The resistance range is
120Ω～10kΩ.
具体接线实例见 7.6 所示。
See 7.6 for specific connection case.
7.1 传输方式 Transmitting Method
信息传输为异步方式，并以字节为单位，在主机和从机之间传递的通讯信息是 10 位字格式，包含 1 个起始
位、8 个数据位（最小的有效位先发送）、无奇偶校验位、1 个停止位，如设置为及奇偶校验位或 2 位停止位，
则为 11 位字格式。
The information transmission is asynchronous and in bytes. The communication message tranmitted from the master
to the slave is in 10-bit format including 1 start bit,8 data bit(LSB first delivered),no parity bit, one stop bit. If parity bit
or 2 stop bit is et, the format is 11-bit.

地址码：地址码在帧的开始部分，由一个字节（8 位二进制码）组成，十进制为 0～255，在 PZ 仪表中只使
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。
每个终端设备的地址必须是唯一的，仅仅被寻址到的终端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。
Address code: the address code is in the beginning of the frame, which is composed of a byte (8 bit binary
code)representing 0~255 in decimal system. The PZ instrument only uses 1 ～247 and keeps other addresses. The bits
indicate the address of the terminal device designated by the user. The device will receive the data from the linked master.

`
12
The address of every terminal device must be unique. Only the end addressed will correspond to the query containing its
address. When the terminal sends back a response, the responding slave address will tell the master which terminal is
communicating with it.
功能码：功能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。
Function code: the function code tells the addressed termnial to carry out which functions. The table below lists up
the function codes used by this instrument as well as their meanings and funcitons.

操作

03H/04H
读数据寄存器

获得一个或多个寄存器的当前二进制值
Obtaining the current binary value of one or more
registers.
10H
预置多寄存器
Preset multi-register
设定二进制值到一系列多寄存器中
Set the binary value into a series of multi-register
数据区：数据区包含了终端执行特定功能所需要的数据或者终端响应查询时采集到的数据。这些数据的内容
可能是数值、参考地址或者设置值。例如：功能码告诉终端读取一个寄存器，数据区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内容而有所不同。
Data zone: the data zone contains the data needed for carrying out certain functions or collected when the terminal
responds to the query. The content of the data may be number, reference address or set value. For example: if the
function code tells the terminal to read a register,the data zone needs to specifiy which register to start with and how
much data to be read. The embedded address and data will vary with types and different content of the slaves.
CRC 效验码：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，接收设备在接收数据时重新计算 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。
CRC check code:CRC field occupies two bytes including one 16-bit binary value. The CRC value is calculated by
the transmitting devicie then added to the data frame. The receiving device will recalculate the CRC value upon
receiving the data then compare it with the received value in the CRC field. If the two values are not identical, there is an
error.
生成一个 CRC 的流程为：The procedure to generate a CRC
a、预置一个 16 位寄存器为 0FFFFH（全 1），称之为 CRC 寄存器。
Preset a 16-bit register as 0FFFFH (full 1), which is called CRC register.
b、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。
Make XOR calculation with 8 bit of the first byte in the data frame and the lower byte in the CRC register and store
the result into the CRC register.
c、将 CRC 寄存器向右移一位，最高位填以 0，最低位移出并检测。
Shift the CRC register right a bit and fill the MSB with 0 and take out the LSB for checking.
d、如果最低位为 0，重复第三步（下一次移位）；如果最低位为 1，将 CRC 寄存器与一个预设的固定值（0A001H）
进行异或运算。
If the LSB is 0, repeat step 3 (one more shift); if the LSB is 1, m,ake XOR calculation with CRC register and
preset fixed value (0A001H).

`
13
e、重复第三步和第四步直到 8 次移位。这样处理完了一个完整的八位。
Repeat step three and step four until the 8th shift. The entire 8 bit processing is complete in this way.
f、重复第 2 步到第 5 步来处理下一个八位，直到所有的字节处理结束。
Repeat step two to five to process the next 8 bits until all bytes are processed.
g、最终 CRC 寄存器的值就是 CRC 的值。
Finally, the CRC register value becomes the CRC value.
此外还有一种利用预设的表格计算 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，请参阅相关资料
Besides, there is also a wayt to calculate CRC using the preset table. It is characterized by rapid calculation speed.
However, the table needs relatively large storage room. We will not introduce it here, please refer to relevant materials.
7.3 功能码简介 Function Code Introduction

bytes):UAB, UBC, UCA. Among them, UAB’s address is 0028H, UBC’s address is 0029H and UCA’s address is
002AH.

7.3.2 功能码 10H：写寄存器 Function Code 10H: Writing Register
功能码 10H 允许用户改变多个寄存器的内容，该仪表中系统参数、开关量输出状态等可用此功能号写入。
主机一次最多可以写入 16 个(32 字节)数据。
The function code 10H allows the user to change the contents of multiple registers. The function code can be used

`
14
to write the system parameters and switch output status. The master computer can write a maximum of 16 pieces of data
(32 bytes) at once.
下面的例子是预置地址为01的仪表输出开关量Do1。开关量输入/输出状态指示寄存器地址为0022H，第9-12
位对应DI1-DI4, 第13-14位分别对应DO1-DO2。
The following example shows than when the preset address is 01, the switch output is Do1. The switch input/output
status indication register’s address is 0022H. The 9-12 bit corresponds to DI1-DI4, the 13-14 bit corresponds to D01-D02
respectively.
