utgard访问OPC server

utgard是一个开源的项目，基于j-interop做的，用于和OPC SERVER通讯。

j-interop是纯java封装的用于COM/DCOM通讯的开源项目，这样就不必使用JNI

首先说下环境：

我的电脑是WIN7 64操作系统

eclipse3.3

OPC SERVER采用 samtatic net

本文目的：通过utgard与OPC SERVER通讯，从而达到控制PLC的功能。

下面是程序配置：

1、导入jar包

 

2、测试main程序(附件中的Test.java)

 

import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.Executors;

import org.jinterop.dcom.common.JIException;
import org.jinterop.dcom.core.JIVariant;
import org.openscada.opc.lib.common.ConnectionInformation;
import org.openscada.opc.lib.da.Group;
import org.openscada.opc.lib.da.Item;
import org.openscada.opc.lib.da.ItemState;
import org.openscada.opc.lib.da.Server;
import org.openscada.opc.lib.da.browser.Branch;
import org.openscada.opc.lib.da.browser.Leaf;


public class Test {
    public static void main ( final String[] args ) throws Throwable
    {
        // create connection information
        final ConnectionInformation ci = new ConnectionInformation ();
        ci.setHost("127.0.0.1");
        ci.setDomain("");
        // ci.setProgId("Matrikon.OPC.Simulation.1");
        ci.setProgId("OPC.SimaticNET"); //s7 注意 使用progId必须要求dcom配置正确
        //ci.setClsid("F8582CF2-88FB-11D0-B850-00C0F0104305");//other
        //ci.setClsid("B6EACB30-42D5-11D0-9517-0020AFAA4B3C");// simatic S7
        ci.setUser("Administrator");
        ci.setPassword("asd3839729");

        // create a new server
        final Server server = new Server ( ci, Executors.newSingleThreadScheduledExecutor () );
        try
        {
        	server.connect ();

	        Group group = server.addGroup ( "group" );
	        // group is initially active ... just for demonstration
	        group.setActive ( true );
	
	        // Add a new item to the group
	        final Item item = group.addItem ( "S7:[@LOCALSERVER]DB1,W0" );
	
	        String[] test = new String[]{"S7:[@LOCALSERVER]DB1,W2","S7:[@LOCALSERVER]DB1,W1"};
	
	            
	        Map<String,Item> map = new HashMap<String,Item>();
	        map = group.addItems(test);
	        
	        
	        System.out.println(map.keySet());
	        for(String s : map.keySet()){
	        	Item it = map.get(s);
	        	System.out.println(s + " ===============  " + it.read(true).getValue().getObjectAsUnsigned().getValue());
	        }
            
            
		    // Items are initially active ... just for demonstration
		    item.setActive ( true );
		    item.write(new  JIVariant("121"));
		    
		    System.out.println(item.read(true).getValue().getObjectAsUnsigned().getValue() + "  <------==");
		    
		    // Add some more items ... including one that is already existing
		   // final Map<String, Item> items = group.addItems ( "Saw-toothed Waves.Int2", "Saw-toothed Waves.Int4" );

            
        }
        catch ( final JIException e )
        {
            System.out.println ( String.format ( "%08X: %s", e.getErrorCode (), server.getErrorMessage ( e.getErrorCode () ) ) );
        }
    }
}

 

 

注：

a：诸如S7:[@LOCALSERVER]DB1,W0是我通过在本地OPC SERVER中定义的PLC地址，通过OPC SCOUT可以定义、查看

b：ProgId 其实就是注册表中的名称，对应的值就是Clsid 这些可以在注册表中找到，这里我的progid是OPC.SimaticNET，就是通过这个名称找到了它的值B6EACB30-42D5-11D0-9517-0020AFAA4B3C

需要注意的是，如果使用OPC.SimaticNet，你电脑的OPC SERVER的DCOM必须配置成功，否则连接不上，也或者直接用 setClsid("B6EACB30-42D5-11D0-9517-0020AFAA4B3C")，效果一样，WIN7 64位设置OPC SERVER DCOM与XP不太一样，附件  《Win7和Win7_SP1网络OPC配置.pdf》是详细配置步骤。

 

最近在研究J-INTEROP与DCOM的通讯，也是刚刚接触，希望有兴趣的一起探讨探讨。

你好，报错如下，是什么原因？

8 楼 讨厌淡紫色 2016-04-26  

我这边总是提示org.openscada.opc.lib.da.Group.addItems报错，opc server已经连接上了，请问下是什么原因

7 楼 tandemon 2015-05-04  

你好，我用的是Matrikon OPC的server，用你的代码总是添加不进数据，请问是什么原因？

6 楼 LeoLi_1221 2014-11-18  

请教楼主！
// add sync access采用监听模式
final AccessBase access = new Async20Access(server, 6000, true);
for(final String itemId : items){
access.addItem(itemId, new DataCallback(){
public void changed(Item item, ItemState state){
System.out.println(item.getId()+"-----------11-------"+state);
}
});
}
采用订阅方式与OPC Server连接，为什么读取一段时间的数据后，会报如下的错误呢？

我的总报没有联结到OPC服务器,请问需要注意哪些问题吗？

估计是没有给对clsid，先试试吧，或者把代码贴出来看看，截止到连接opcserver那就行

我以前用的JeasyOPc ,现在准备用UTGARD,请问一下在本机联OPC ，也要配置DCOM吗？
我的没有调 通。

本机连接可以不用配置，但是不能是用Clsid，只能使用progID
如 ci.setProgId("OPC.SimaticNET");就不能用，必须使用Clsid方式：//ci.setClsid("B6EACB30-42D5-11D0-9517-0020AFAA4B3C");// simatic S7
上面的clsid是SimaticNET的，不知道你用的是什么OPC SERVER
