最近在处理Java与西门子PLC通信的，摸索出通信方法，实现了java与西门子PLC间相互通信，可以方便的实现西门子PLC实现功能后，怎么做人机交互、APP控制等功能。

import com.github.s7connector.api.annotation.S7Variable;
    import com.github.s7connector.impl.utils.S7Type;
    public class PlcDb { 
    	@S7Variable(type = S7Type.BOOL, byteOffset = 0, bitOffset = 0)
        public boolean aaa;
    
        @S7Variable(type = S7Type.STRING, byteOffset = 2, bitOffset=0, size=10)
        public String bbb;
            
        @S7Variable(type = S7Type.BYTE, byteOffset = 258)
        public byte ccc;
    	public boolean isAaa() { 
    		return aaa;
    	}
    	public void setAaa(boolean aaa) { 
    		this.aaa = aaa;

    	}
    }

使用开源包

public static void main(String[] args) throws IOException, NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException { 
    		// TODO Auto-generated method stub
    		S7Connector connector = S7ConnectorFactory
                    .buildTCPConnector()
                    .withHost("192.168.253.49")
                    .withPort(102)
                    .withTimeout(10000)
                    .withRack(0) //optional
                    .withSlot(2) //optional
                    .build();
    
    		S7Serializer s7Serializer = S7SerializerFactory.buildSerializer(connector);
    		//开始读PLC数据
            if (null != connector) {         	
                S7Serializer serializer = S7SerializerFactory.buildSerializer(connector);
                //读数据
                PlcDb plcDbread = serializer.dispense(PlcDb.class, 1, 0);
                System.out.println("写入前数据-->"+JSON.toJSONString(plcDbread));
                
                //写数据
                PlcDb plcstr =new PlcDb();
                plcstr.setAaa(false);
                plcstr.setBbb("ABC00001");
                byte a = 2; 
                plcstr.setCcc(a);
                serializer.store(plcstr, 1, 0);
                
                //读数据
                plcDbread = serializer.dispense(PlcDb.class, 1, 0);
                System.out.println("写入后数据-->"+JSON.toJSONString(plcDbread));
                
                connector.close();
            }  
    		}
