This is the solution

The assignment error of the variable writeData is removed (Error: can not convert from int to int [])
I get an error 'Starting address invalid or starting address + quantity invalid'

When I run the program, I'm a little raw on this, sorry.

Hi, I found this.
Would I have to send you this form of characters?

COMMAND CODE：03, READ MULTIPLE
REGISTER (T, C, D)
What is the maximum number of registers that can be read?
Example: Read coils T20~T27 from Slave ID#01
Master→ELC “: 01 03 06 14 00 08 DA CR LF”
Sent message:
Field Name ASCII
STX 3A (Hex)
Slave Address 01
Command code 03
Starting Address Hi 06
Starting Address Lo 14
Number of Points Hi 00
Number of Points Lo 08
Error Check (LRC) DA
END 1 0D
END 0 0A (Hex)

I do not understand.

In this area of the code I ask for the address of the record that I am going to use and the number:
int[] response = modbustcp.ReadInputRegisters(startAddres, quantity);
Any suggestions.

The code that I am using is this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using EasyModbus;

namespace comunicacion_tcp
{
class Program
{
private string IpAddress = "192.168.178.111";
private int port = 502;
private ushort startAddres = 258;
private ushort quantity = 1;
private ModbusClient modbustcp;
public Program()
{
modbustcp = new ModbusClient(IpAddress, port);
modbustcp.Connect();

int[] response = modbustcp.ReadInputRegisters(startAddres, quantity);
modbustcp.Disconnect();
Console.WriteLine("value of input register 1" + response[0].ToString());
Console.WriteLine("value of input register 2" + response[1].ToString());
}
static void Main(string[] args)
{
Program _program = new Program();
Console.ReadKey();
}
}
}
