在本章主要讲述如何利用软件通过通讯口来操控该系列仪表。本章内容的掌握需要您具有 MODBUS 协议的
知识储备并且通读了本册其他章节所有内容，对本产品功能和应用概念有较全面的了解。
This chapter focuses on how to use software to manipulate the series of instruments through a communication port.
The mastery of the content of this chapter requires that you have the knowledge reserve of MODBUS protocol and read
all the contents of the other chapters of this book, and have a comprehensive understanding of the functions and
application concepts of the product.
本章内容包括：MODBUS 协议简述，通讯应用格式详解，本机的应用细节及参量地址表。
The contents of this chapter include: brief introduction of MODBUS protocol, details of communication application
format, application details of the machine and parameter address table.
3.1 协议简述
3.1 The protocol explanation
3.1.1 传输方式
3.1.1 Transmission format
传输方式是指一个数据帧内，一系列独立的数据结构以及用于传输的数据的有限规则，下面定义了与
MODBUS 协议（RTU 方式）相兼容的传输方式。
Transport refers to a data frame, a series of separate data structure and used for the transmission of data to limited
rules, the following defines that is compatible with the MODBUS protocol (RTU) transmission mode.
每个字节的位
Bits per byte
 1个起始位
 1 start bit
 8个数据位，最小的有效位先发送
 8 data bits, the smallest valid bit is sent firstly
 无奇偶校验位
 Unexciting parity bit
 1个停止位
 1 stop bit
错误检测：CRC（循环冗余校验）
Error detection: CRC (Cyclic redundancy check)
3.1.2 协议
3.1.2 Protocol
当数据帧到达终端设备时，它通过一个简单的“端口”进入被寻址的设备，该设备去掉数据帧的“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。返回的响应数据帧中包含了以下内容：终端从机地址（Address）、被执行了的命令
（Function）、执行命令生成的被请求数据（Data）和一个校验码（Check）。发生任何错误都不会有成功的响应。
When data frames to terminal equipment, it by a simple "ports" to be addressing device, the device to remove the
"envelope" data frames (data), read the data, if there are no mistakes, will carry out the tasks of the requested data, then,
it will generate its own data to join the "envelope" of the data frame is returned to the sender. The response returned Data
frame contains the following contents: the terminal Address (Address), was carried out from the machine's command
(Function), execute the command to generate the requested Data (Data) and a Check code (Check). There will be no

11
successful response to any errors.
3.1.2.1 数据帧格式
3.1.2.1 Data frame format
Address Function Data Check
8-bits 8-bits N×8-bits 16-bits
3.1.2.2 地址域
3.1.2.2 Address code
地址域在帧的开始部分，由一个字节（8位二进制码）组成，十进制为 0～255，在我们的系统中只留用 1～
247，其它地址保留。这些位标明了用户指定的终端设备地址，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讯。
The Address is at head of the data, and it has 1 byte (8-bits binary code). The decimal is 0~255. In ARTM, it just
uses 1~247. It stores the slave address. These bits indicate the address of the terminal device specified by the user, which
will receive the host data that is connected to it. The address of each terminal device must be only one, and only the
addressable terminal will respond to the query containing the address. When the terminal sends back a response, the data
from the machine address in the response tells the host which terminal is communicating with it.
3.1.2.3 功能域
3.1.2.3 Function code
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。
The functional domain code tells what function the addressable terminal performs. The following table lists the
functional codes used in this series of instruments, as well as their meanings and functions.

设定二进制值到一系列多寄存器中
Put the binary value into multi hold register
3.1.2.4 数据域
3.1.2.4 Data code
数据域包括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：功能域码告诉终端读取一个寄存器，数据域则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。
The data domain includes the data that the terminal needs to perform a particular function, or the data collected
when the terminal responds to the query. The contents of these data may be numeric, reference addresses, or set values.
For example, code tells terminal functional domains to read from a register, data domain to indicate the starting which
register and read how many data, the embedded address and data in accordance with the type and different content varies
between machine.
3.1.2.5 错误校验域
3.1.2.5 Check code
该域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，一组数据在从一个设备传输到
另一个设备时在线路上可能会发生一些改变，出错校验能够保证主机或者终端不去响应那些传输过程中发生了改
变的数据，这就提高了系统的安全性和效率，错误校验使用了 16 位循环冗余的方法。
This code allows the error of transmission between the master and slave. Sometimes, there will be the errors when a
data transferred from equipment to another in the interference due to the electrical noise and other disturbances. The
check code can make the slave not to answer the error data in the transmission. This improves the security and efficiency

of the system. Check node uses 16-bits cyclic redundancy.
3.1.3 错误检测的方法
3.1.3 Check mode
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 值有传输设备计算出来，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，然后与就收到的 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 occupies 2 bytes, and it contains a binary value of 16 bits. It is got by the transmission equipment, and than it
is added in the data frame. The master will recalculate the CRC value, and then it compares the value to that received. If
2 values is not same, there must be 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，起始位和终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，则不作任何处理。
The CRC algorithm, you will preset a 16-bit register all to 1, then each byte in the data frame of eight consecutive
operation with the current value of the register, only 8 bits of each byte in generate CRC, start bit and stop bit and the
possibility of using parity bit does not affect the CRC. When generate CRC, each byte of eight different XOR with the
contents of the registers, then the results to the low displacement, high use 0, lowest (LSB) removed and test, if it is 1,
the register is fixed with a preset value (0A001H) for an XOR operation, if the lowest is 0, do not make any processing.
上述处理重复进行，直到执行完了 8次移位操作，当最后一位（第 8位）移位完成以后，下一个 8位字节与
寄存器的当前值进行异或运算，同样进行上述的另一个 8次移位异或操作，当数据帧中的所有字节都作了处理，
生成的最终值就是 CRC 值。
The above process repeated, until the end of the eight times perform shift operation, when the last one (eighth) after
the completion of the shift, an 8-bit bytes and register under the current value of XOR operation, another eight times for
the same shift XOR operation, when all the bytes of a data frame processing, generate the final value is CRC value.
生成一个 CRC 的流程为：
The process of generating a CRC is:
1、 预置一个 16 位寄存器为 0FFFFH（全 1），称之为 CRC 寄存器。
1、 Preset a 16-bit register to be 0FFFFH (all 1), which is called CRC register.
2、 把数据帧的第一个字节的 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。
2、XORing the 8 bits of the first byte of the data frame with the low byte in the CRC register, and the result is saved
back to the CRC register.
3、 将CRC 寄存器向右移一位，最高位填以 0，最低位移出并检测。
3、Move the CRC register to the right one, the highest position is 0, and the minimum displacement is detected.
4、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。
4、If the lowest level is 0: repeat step 3 (the next shift);If the lowest level is 1: the CRC register is XORed with a
preset fixed value (0A001H).
5、 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 8位。
5、Repeat step 3 and step 4 up to 8 shifts. This completes a complete 8 bit.
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。
6、Repeat step 2 to step 5 to handle the next 8 bit, knowing that all byte processing ends.
7、 最终 CRC 寄存器的值就是 CRC 的值。
7、The value of the final CRC register is the value of CRC.
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。

In addition, there is a way to use the default form of CRC calculation method, its main characteristic is computing
speed, but the form needs large storage space, the method is no longer here, please refer to the relevant information.
