四、软件设计
本模块设计结构，从功能上可以设计成两种工作模式：Modbus TCP从站模式，Modbus TCP主站模式。Modbus TCP从站模式，是把以太网总线Modbus TCP请求转化成串口总线Modbus RTU请求，也就是以太网设备从PLC读出数据；Modbus TCP主站模式，是把串口总线Modbus RTU请求转化成以太网Modbus TCP请求，也就是PLC从以太网设备读入数据。下面以Modbus TCP从站模式为例。
4.1 模块配置
表1 拨码功能配置表模块配置主要是通过8位拨码开关实现，通过这拨码开关配置模块的工作模式，以太网IP地址，串口RTU地址，波特率。如表1所示：
8位拨码配置
4.2 以太网驱动开发
驱动开发包括两部份：芯片物理层驱动(MAC，PHY)和TCP/IP协议层驱动。芯片物理层驱动主要是对LPC1758的以太网控制器和PHY芯片的初始化和控制输入输出的函数化打包，以便供TCP/IP协议层驱动调用。TCP/IP协议层驱动开发需要参考TCP/IP标准协议，下图4比较清晰明了的介绍TCP/IP协议状态变化图③。
图4 TCP的状态变迁图
对于从站模式（服务器模式），每一个TCP请求连接对应一组状态图，把这些状态归纳入一个结构体，然后再创建结构体链表，系统程序通过维护监测链表，可以实现多客户端同时请求通讯。
4.3 Modbus TCP和Modbus RTU协议开发
参考Modbus TCP和Modbus RTU协议标准，不难实现PLC与本模块的Modbus RTU以及本模块与外部以太网设备的Modbus TCP数据通讯。然后在本模块程序内部完成数据包的Modbus TCP和Modbus RTU之间数据转换，采用透明传输方式，即把从一个端口接收出来的数据转换后立即从另一个端口输出去。Modbus TCP相比Modbus RTU报文格式，多了六个字节的前缀，少了后面的CRC校验，它是采用TCP/IP 和链路层（以太网）校验和机制来校验分组交换的准确性。
