Modbus由MODICON公司于1979年开发，是一种工业现场总线协议标准。1996年施耐德公司推出基于以太网TCP/IP的Modbus协议：ModbusTCP。Modbus协议是一项应用层报文传输协议，包括ASCII、RTU、TCP三种报文类型。标准的Modbus协议物理层接口有RS232、RS422、RS485和以太网接口，采用master/slave方式通信。
ModbusTCP的数据帧可分为两部分：MBAP+PDU。
MBAP为报文头，长度为7字节，组成如下：事务处理标识+协议标识+长度+单元标识
				
Tips：
　　1、目前NetCore下与Modbus通信的框架主要选择了Modbus.Net https://github.com/parallelbgls/Modbus.Net
　　2、modbus是常用的工业通信协议，在软件调试时可以通过modbus poll+slave模拟通信通过达到调试目的，下图是我使用软件
      1）为串口模拟工具
				
NModbus is a C# implementation of the Modbus protocol. Provides connectivity to Modbus slave compatible devices and applications. Supports serial ASCII, serial RTU, TCP, and UDP protocols. NModbus4 it's a fork of NModbus(https://code.google.com/p/nmodbus). NModbus4 differs from original NModbus in following:
1.removed USB support(FtdAdapter.dll)
2.removed log4net dependency
3.removed Unme.Common.dll dependency
4.assembly renamed to NModbus4.dll
5.target framework changed to .NET 4

MODBUS TCP 03功能码报文解析

初识Modbus TCP-------------C#编写Modbus TCP客户端程序(二）
0. 软件描述
目前此上位机软件一共有四个版本：
上位机软件v1.0版本功能：可以设置服务器的IP地址与端口号。客户端只能发送固定的报文，并接收服务器返回的报文，若要改变发送的报文，需要在程序中进行更改。
上位机软件v1.1版本功能：在v1.0基础上增加了
二、Modbus
1.最近在做Modbus有关的工作，根据杨更更的 Modbus软件开发实战  里面都是基于VS的很适合我这种C#开发人员，首先根据书里面的介绍LiModbus直接敲代码就OK，敲完自行测试哈，这里就暂时不多缀余。这个是基于C++
2.Nmodbus这个是基于C#开源的代码 网上也有先下载下来再说https://git...
				
web 编写遵循的核心协议就是http/tcp 协议。而这个核心的内容是就Socket编程。
Socket 是点对点的通讯模式，是全双工的。是靠IP地址进行寻址访问的。
根据设计又几种模式： 点对点 （适合两者之间大文件的传输） 服务器模式（聊天，webapi等）
这里主要讨论: 服务器模式
Socket 编程需要引用
