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();
