1.任务详情
- Java实现OPC通信的代码实现
- 最终实现对西门子的S7-300的PLC变量的值读写
2.实现情况
- 使用utgard实现通信：Java实现OPC通信
- OPCserver：KEPserver6
- 配置DCOM：OPC和DCOM配置
- 制定变量列表：规定名称和类型
说明
- PC和PLC通信，PC用TAG1之类的地址，PLC用BD1.INT05之类的地址，个人总结的表格，方便说明
| OPCServer上定义的地址名称 | 硬件PLC上的地址 | 数据类型 | 说明：这个地址做什么用的 |
|---|---|---|---|
| TAG1 | DB1.INT00 | short | 心跳 |
| TAG2 | DB1.INT02 | short | 控制字 |
| TAG3 | DB1.STRING4,10 | string | 箱体信息 |
| TAG4 | DB1.D14 | float | 结果 |
- 地址定义在OPCServer上，实际截图
- 制定交互流程：控制字的状态
- 心跳变量：TAG1，表示软件和硬件(这里是PLC)连接状态，这个是自己随便定义的，我的是：PLC一直写1，PC收到1写2，5秒内一直收不到1就是断开了。
- 控制字(状态变量)：TAG2，作用是作为一个控制字，控制整个交互的流程，当是不同值时，PLC和PC要进行指定的读写动作。
这是我一开始画的
这是后来画的，就是PC和PLC的交互，比较清晰了
实际的PLC地址编辑界面截图
3. 代码实现
- 按照官方例子写了一个通信类：通过配置信息，启动server，添加要读取的地址
- 配置信息是单独一个类：从配置文件读取IP什么的
- 然后是回调函数：某个地址，读到了某个值要怎么做，，在这就2个回调，心跳TAG1：读到1写入2，5秒超时，TAG2：是某个值时，怎么做。。。
- 读值和写值可以单独算一个方法类：我用到的数据类型就是几个，short，string，Long Array，对应写了几个方法
- OPCServer上的地址配置也算是一个单独的类：我写在配置文件了，当时犹豫是不是放到数据库，感觉差别不大
- Utgard有两种数据访问方式——直接通过item的read/write方法或者使用AccessBase（读取数据）
- 心跳TAG1：PC写2，PLC写1，逻辑是PC收到1写2，超时提示
- 控制字TAG2：PLC写0,1,3,4,5,6/7，PC写2,8
- PC在写TAG2=1时，同时写入TAG3值
- PLC在写TAG2=6/7时，同时写入TAG4值
- 读线程：每隔500ms读一次值，读到值后执行回调方法DataCallback()
- 不用另起线程，直接用这个Access线程循环读取控制字的值，回调方法对应调用item的read/write方法读写值
final AccessBase access = new SyncAccess(server, 500);
access.addItem(itemId, new DataCallback() {
@Override
public void changed(Item item, ItemState state) {
System.out.println("-----" + state);
}
});
// start reading
access.bind();
