Python TCP/IP PLC客户端到Java语言的演示

Question

我有一个用python制作的西门子s1200 plc TCP/IP客户端演示。我在Youtube上找到了它：https://www.youtube.com/watch?v=5KLLeQeB2EY

我的问题是，如何将这些代码翻译成java程序。我目前正在做一个项目，将数据从plc读取到java客户机（后来从java读取到plc），我目前被这个项目卡住了

这个python演示在运行时在控制台上写入“testi1”字符串，我希望从“output1”数据块中获得更多数据。附加的数据块图片

请帮忙

干杯

import socket

HOST = '192.168.0.1' #plc ip
PORT = 2000 # plc port

if __name__ == "__main__":
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as conn:
        conn.connect((HOST, PORT))
        print(conn.recv(1024).decode('UTF-8', errors='ignore')) #.decode('UTF-8', errors='ignore') erases some nonsense output

data block "output1"

一个简单的Ping模型

客户端类

import java.io.OutputStream;
import java.io.InputStream
import java.net.InetSocketAddress;
import java.net.Socket;


class Client 
{
 public static void main(String args[])
 {
  try(Socket client=new Socket())
  {
   client.connect(new InetSocketAddress("localhost",8000));

   Scanner scanner=new Scanner(System.in);
   String input;

 
   try(OutputStream out=client.getOutputStream();
        InputStream in=client.getInputStream())
   {
    while(!(input=scanner.nextLine()).equals("Bye"))
    { 
     out.write(input.getBytes());

     System.out.println("Server said "+new String(in.readAllBytes()));
    }
   }
   catch(IOException ex){ex.printStackTrace();}     
  }
  catch(IOException ex){ex.printStackTrace();}
 }
}

服务器类

import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import java.net.ServerSocket;
import java.net.Socket;


class Server 
{
 public static void main(String args[])
 {
  try(ServerSocket server=new ServerSocket())
  {
   server.bind(new InetSocketAddress("localhost",8000));
   System.out.println("Server Online");
   
   try(Socket client=server.accept())
   {
     try(InputStream in=client.getInputStream();
         OutputStream out=client.getOutputStream())
     {         
      while(true)
      { 
       String response=new String(in.readAllBytes());
       if(response.equals("Bye")){break;}
       else{out.write(("Echo "+response).getBytes());}
      }
     }
   catch(IOException ex){ex.printStackTrace();}
  }
  catch(IOException ex){ex.printStackTrace();}
 }
}

您可以根据自己的目的对其进行建模
