Связь между visual studio C # и ПЛК

---

Hello,

I need to make a system in Visual Studio (C #) that allows me to communicate with the PLC, I am using Delta PLC DVP28SV and Delta module DVPEN01.


I was reading the MODBUS TCP / IP communication, I can not understand.

How would you send the information to a specific PLC register from C # and how to identify that registry?

I would appreciate if someone could guide me on the subject.

Greetings.

Что я уже пробовал:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.NetworkInformation;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using ModbusTcp;


namespace Console_ping_Sr2_Electronico
{
    class Program
    {
        static void Main(string[] args)
        {

            System.Net.NetworkInformation.Ping Pings = new System.Net.NetworkInformation.Ping();
            int timeout = 1000;
            int i = 0;
            while (i != 1)
            {
                {
                    if (Pings.Send("192.168.178.111", timeout).Status == IPStatus.Success)
                    {
                        Console.WriteLine("Exito");
                        Thread.Sleep(2000);
                        Console.Clear();
                    }
                    else
                    {
                        
                            Console.WriteLine("Error");
                        Thread.Sleep(2000);
                        Console.Clear();

                    }
                }
            }
        }
