先介绍下一些基本定义
串行通信：通过的是PLC上的串行口RS232/RS422/485口，上位机链接系统 Hostlink系统是对于FA系统一种及优化有经济的通信方式。
适用于一台上位机与一台或者多台的PLC进行数据通信。
通讯协议分两种
1:C-mode commands
只可以通过串口进行通讯
2:Fins commands
既可以通过串口通讯也可以通过各类网络通讯(适应性较强)
本文只介绍fins通讯
fins (factory in terfave network service) 通讯协议是欧姆龙公司开发的一款自动化控制网络指令/响应系统的通讯协议；运用FINS指令可实现各种网络间的无缝通信
FINS帧结构
- 发送命令结构 命令码2个字节
- 响应命令结构 命令码2个字节
- 命令码 01 01读数据
- 命令码 01 02写数据
- 结束码 00 00无错误
1、获取PLC节点地址
上位机和PLC建立TCP通讯之后，可以发送以下命令来获得PLC的节点地址;
帧结构见下表：
| 列表 | Content（十六进制） | Description(说明) |
|---|---|---|
| 头 | 46 49 4E 53 | ASCII分别代表的是 F I N S |
| 长度 | 00 00 00 0C | 从Command之后的数据包的长度 |
| 错误代码 | 00 00 00 00 | 目前暂时没用，因为在服务器不需要检测内部错误 |
| 连接的节点地址 | 00000000~000000FE | 分别是0~254，当设置为0时表示自动获取客户端的Fins节点地址 |
2、命令码介绍
详细内容说明介绍见下表：
| 命令内容 | 命令代码(MR SR) | 说明 | 功能 |
|---|---|---|---|
| 访问I/O存储区 | 01 01 | 读内存区 | 读连续I/O存储区字的内容 |
| 访问I/O存储区 | 01 02 | 写内存区 | 写连续I/O存储区字的内容 |
| 访问I/O存储区 | 01 03 | 填充内存区 | 将相同的数据写入指定范围的I/O存储器区 |
| 访问I/O存储区 | 01 04 | 多个存储区读取 | 读取指定的非连续I/O存储区字 |
| 访问I/O存储区 | 01 05 | 存储区传输 | 将连续存储I/O存储区字内容复制到另外的I/O存储区 |
| 访问参数区 | 02 01 | 读取参数区 | 读取连续参数区字内容 |
| 访问参数区 | 02 02 | 写入参数区 | 写入连续参数区字内容 |
| 访问参数区 | 02 03 | 填充参数区 | 将相同数据写入到指定范围参数区域字 |
| 改变操作模式 | 04 01 | 设置CPU操作模式为RUN | 将CPU单元的操作模式更改为RUN或MONITOR |
| 改变操作模式 | 04 02 | 设置CPU操作模式为STOP | 将CPU单元的操作模式更改为编程 |
| 改变操作模式 | 06 01 | 读取CPU单元状态 | 读取CPU单元状态 |
| 错误日志 | 21 01 | 错误清除 | 清除错误或错误信息 |
| 错误日志 | 21 02 | 读取错误日志 | 读取错误日志 |
| 错误日志 | 21 03 | 清除错误日志 | 清除错误日志指针 |
3、I / O存储器地址标识
| 区域 | 数据类型 | 存储区代码 | 存储区地址范围 | 存储地址 | 字节长度 |
|---|---|---|---|---|---|
| DM | Bit | 02 | D0000000到D3276715 | 000000到7FFF0F | 1 |
| DM | Word | 82 | D00000到D32767 | 000000到7FFF00 | 2 |
鉴于我们在和PLC通讯时，一般只需要进行读取DM区寄存器操作，因为本文只介绍读取和写入DM区寄存器。其他的有需要的童鞋进行自己功能拓展。
举例：
读取DM区地址100，连续10个地址的数据
发送命令：010182006400000A
返回命令：010100000102030405060708090A
发送的命令进行说明：
- 1、01 01代表功能码，读连续I/O存储区字的内容
- 2、82代表进行字操作
- 3、00 64转成十进制就是100代表的是我们要读取的起始地址
- 4、00000A转成十进制就是10代表的是我们要读取得长度
响应的命令说明
- 1、01 01代表功能码，读连续I/O存储区字的内容
- 2、00 00代表结束码，当不是00 00的时候表明数据帧不对
- 3、01 02 03 04 05 06 07 08 09 0A分别代表要读取的十个寄存器的数据值
具体协议可以查看百度文库：欧姆龙fins通讯协议
综上，结合之前的博客，C#Socket客户端：C#Socket客户端我们可以整合得到一个欧姆龙fins的类，如下所示：
