Socket Communication Setup

Post by samir13k »


I'm trying to write a fairly simple program, I just want to press one button and have it send out a string (in this case "power on") to a universal robot using socket communications.

My robot IP address is
Socket I would like to communicate to is 29999
Script to send is "Power On"

Does anyone have any advice as to where to get started? I'm assuming that I will have to open a socket in C# in the backend of the beijer, however I'm lacking direction... Can anyone point me to a program using socket communications in the Beijer? It seems like most code I see makes this far more complicated than it has to be. Your help is appreciated in advance!

Hi Samir13k,
Here is an example script you can use to create a socket and send data at an interval:


// Press F1 to get help about using script.
// To access an object that is not located in the current class, start the call with Globals.
// When using events and timers be cautious not to generate memoryleaks,
// please see the help for more information.

namespace Neo.ApplicationFramework.Generated
using System.Windows.Forms;
using System;
using System.Drawing;
using Neo.ApplicationFramework.Tools;
using Neo.ApplicationFramework.Common.Graphics.Logic;
using Neo.ApplicationFramework.Controls;
using Neo.ApplicationFramework.Interfaces;
using System.Net.Sockets;
using System.Net;
using System.Threading;
using System.Text;

public partial class Screen1

static System.Windows.Forms.Timer mytimer = new System.Windows.Forms.Timer();
static Thread t;

void Screen1_Opened(System.Object sender, System.EventArgs e)
//t.IsBackground = true;
mytimer.Tick += Run_Timer;
mytimer.Interval = 40;
mytimer.Enabled = true;

private void Run_Timer(System.Object sender, System.EventArgs e)
// MessageBox.Show("Test");
t = new Thread(new ThreadStart(Connect));


private void Connect()

try {

// Establish the remote endpoint
// for the socket. This example
// uses port 11111 on the local
// computer.
IPHostEntry ipHost = Dns.GetHostEntry(Dns.GetHostName());
IPAddress ipAddr = IPAddress.Parse("");

IPEndPoint localEndPoint = new IPEndPoint(ipAddr, 3000);

// Creation TCP/IP Socket using
// Socket Class Costructor
Socket sendersock = new Socket(ipAddr.AddressFamily,
SocketType.Stream, ProtocolType.Tcp);

try {

// Connect Socket to the remote
// endpoint using method Connect()

// We print EndPoint information
// that we are connected

//Console.WriteLine("Socket connected to -> {0} ",

// Creation of messagge that
// we will send to Server
byte[] messageSent = Encoding.ASCII.GetBytes("This is the data that gets sent<EOF>");
int byteSent = sendersock.Send(messageSent);

// Data buffer
byte[] messageReceived = new byte[1024];

// We receive the messagge using
// the method Receive(). This
// method returns number of bytes
// received, that we'll use to
// convert them to string
int byteRecv = sendersock.Receive(messageReceived);
Console.WriteLine("Message from Server -> {0}",
0, byteRecv));

// Close Socket using
// the method Close()

// Manage of Socket's Exceptions

catch (SocketException se) {

//MessageBox.Show("SocketException : {0}", se.ToString());
