Open protocol using C# socket programming for NutRunner.

Introduction  

In one of my projects, I had a chance to create an Atlas Copco PowerFocus (3000/4000) Nutrunner Tools communication using C# socket programming. The main aim of this article is, when I start the Nutrunner tool communication program it was like a blank page. I don’t have an idea of how to complete the task; I was googling for 2 or 3 days but couldn’t find a sample code to communicate with Nutrunner tools using C#. Finally I got a solution using an Open protocol. Today I will explain to you what is:

  1. Atlas Copco PowerFocus (3000/4000) Nutrunner Tools
  2. How to use the Open protocol
  3. C# socket communication program for Nutrunner tool communication

First, we start with:

1. Atlas Copco PowerFocus (3000/4000) Nutrunner Tools

Power Focus 3000/3100 is the latest generation of control and monitoring systems for advanced tightening technology. Power Focus 3000/3100 is a complete solution for the modern assembly industry with high demands and stringent quality and efficiency requirements. The concept offers full modularity through combinations of hardware and software. The PF 4000 is a new generation of control systems suitable for Tensor S, ST, DS, and ETX models. Unlike its predecessor the PF 3100, the PF 4000 is available in one model with two versions (Compact and Graph) that can handle all torque levels. This favors your maintenance budget, since fewer backup units are required.

Simply say Power Focus (3000/4000) is used to read the Torque data. It’s a machine where we can set the Bach Size, Batch Count, Tightening Status, Torque Status, Angle Status, Torque Min limit, Torque Max limit, and etc. We can get the final Torque data, compare the Limit value, and produce the final result.

2. How to use Open protocol

Open protocol is an interface for building applications for remote control or data subscription of controllers. It is platform independent and can be implemented on Linux, PLC, printers, and all Windows platforms for example. The Open protocol supports both serial and Ethernet connections.

Open protocol supports Power Focus and PowerMACS controllers.

Communication

The Open protocol can be run using Ethernet or serial communication. The Open protocol is a full duplex protocol, which means that data can be sent and received at the same time. Every communication partner must be able to operate a send and receive facility simultaneously.

Ethernet protocol

The integrator connects to the controller, and the controller accepts the connection. The controller is the server, and the integrator application is the client. The protocol used is TCP/IP. The default port used for the communication is 4545.

Serial ASCII protocol

All messages sent from the integrator to the controller must be stamped with a four ASCII character tag before the STX character: BEL (ASCII 0x07 bell) HT (ASCII 0x09 horizontal tab) BEL (ASCII 0x07) HT (ASCII 0x09). All messages must be encapsulated between STX (ASCII 0x02 Start of Text) and ETX (ASCII 0x03 End of Text).

Message structure

All information sent over the communication links is in ASCII format. A message consists of three parts: header, data field, and message end. For example here we see how to start a communication. For communication start, we need to use the MID 0001.

Communication messages

MID 0001 Communication start

This message enables the communication. The controller does not respond to any other command before this.

  • Message sent by: Integrator
  • Answers: MID 0002 Communication start acknowledge or MID 0004 Command error, Client already connected.

If the communication is accepted we can receive the result as MID 0002, if not we receive the MID 0004. For more details about Open protocol, please review the attached Open protocol PDF document.

3. C# Socket communication program for Nutrunner tool communication

  1. Connect
  2. Communicate
  3. Data send and receive
  4. Disconnect
The detailed code will be listed below.

Background

The main aim was to develop a simple and easy to use .NET communication program for Atlas Copco Power Focus (3000/4000) – Nutrunner Tool.

Using the code 

The code is very simple and has comments on all functions. The main aim is to make the program very simple and easy to use; all the functions have been well commented in the project.

  1. First we start with namespace declarations.
  2. using System.Net;
    using System.IO;
    using System.Net.Sockets;
  3. Variable declarations:
  4. Socket server;// Declare your Socket
    IPEndPoint ip; // Declare your IPEndpoint
  5. Connect (to connect the Nutrunner tool for communication).
  6. For connection we need the Nutrunner tool IP address. Here my tool's IP address is “10.126.224.186” and the default port for communication is “4545”. Cross check with your hardware engineer for the port used on your tools. Here we use the socket communication program for connection. After the connection is OK, we need to send the Communication Start signal to the NutRunner tool “ MID 0001” – (“00200001000000000000#).

    Server.Send()

    String szData = "00200001000000000000#";//Nutrunner Communication Start
    byte[] byData = Encoding.Default.GetBytes(szData);//convert the string as Byte
    int sent = server.Send(byData, SocketFlags.None);

    server.Receive()

    byte[] bytesFrom = new byte[1025];
    int iRx = server.Receive(bytesFrom);
    string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
    String resultchk = dataFromClient.Substring(4, 4).ToString();

    If we receive MID 0002 as result, then the communication start is successful. If we receive MID 0004 as result then there is an error in the communication start. The detail connect functions:

    private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            String ipaddress = “10.126.224.186”;
            ip = new IPEndPoint(IPAddress.Parse(ipaddress), 4545);
            server.Connect(ip);
            
            label2.BackColor = System.Drawing.Color.GreenYellow;
            label2.Text = "Connected";
            connectServer();
        }
        catch (Exception ex)
        {
        }
    }
    
    private void connectServer()
    {
        try
        {
            if (server.Connected == false)
            {
                label2.BackColor = System.Drawing.Color.Red;
                server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                String ipaddress = textips.Text.Trim();
                ip = new IPEndPoint(IPAddress.Parse(ipaddress), 4545);
                server.Connect(ip);
                label2.BackColor = System.Drawing.Color.GreenYellow;
                label2.Text = "Connected";
            }
            if (server.Connected == true)
            {
                String szData = "00200001000000000000#";//Nutrunner Communication Start
                byte[] byData = Encoding.Default.GetBytes(szData);//System.Text.Encoding.ASCII.GetBytes(szData);
    
                int sent = server.Send(byData, SocketFlags.None);
                byte[] bytesFrom = new byte[1025];
                //  string bytesSent = server.Send(
                int iRx = server.Receive(bytesFrom);
                string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
                String resultchk = dataFromClient.Substring(4, 4).ToString();
    
                ////String szData = "00200060000000000000#";//Nutrunner Communication Start
                ////byte[] byData = Encoding.Default.GetBytes(szData);//System.Text.Encoding.ASCII.GetBytes(szData);
                ////int sent = server.Send(byData, SocketFlags.None);
                timer1.Enabled = true;
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message.ToString());
        }
    }
  7. Torque Data Receive
  8. Here in my program I have used a Timer control for Torque data receive. In the timer we frequently check for the connection. If connection fails we reconnect to the NutRunner tools. To receive the Torque data we use the message ID MID 0060. For Torque data receive, we send the MID 0060 to the Nutrunner tool.

    MID 0060 Last tightening result data subscribe

    Set the subscription for the result tightening. The result of this command will be the transmission of the tightening result after the tightening is performed (push function). The MID revision in the header is used to subscribe to different revisions of MID 0061 Last tightening result data upload reply.

    • Message sent by: Integrator
    • Answer: MID 0005 Command accepted or MID 0004 Command error, Last tightening subscription already exists or MID revision not supported

    Send data to get Torque result:

    String szData = "00200060000000000000#";//Torque data Request Send
    byte[] byData = Encoding.Default.GetBytes(szData);
    int sent = server.Send(byData, SocketFlags.None);

    Receive Torque result

    byte[] bytesFrom = new byte[1025];
    int iRx = server.Receive(bytesFrom);
    string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
    String resultchk = dataFromClient.Substring(4, 4).ToString();

    We receive MID 0061 as result with the Torque data. We will receive the result data something like this: "023100610010 010001020103airbag7 04KPOL3456JKLO897 05000600307000008000009010011112000840 130014001400120015000739160000017099991800000 1900000202001-06-02:09:54:09212001-05-29:12:34:3322123345675 NUL". Format the result string and get the Torque final result. For example, I have used the substring and get the final torque result here:

    txtfinaltorque.Text = dataFromClient.Substring(132, 6).ToString();

    The detailed timer code:

    private void timer1_Tick(object sender, EventArgs e)
    {
        try
        {
            if (server.Connected == false)
            {
                label2.BackColor = System.Drawing.Color.Red;
                label2.Text = "Not Connected";
                server.Disconnect(true);
                server.Close();
                server.Dispose();
                connectServer();
            }
            String szData = "00200060000000000000#";//Nutrunner Communication Start
            byte[] byData = Encoding.Default.GetBytes(szData);//System.Text.Encoding.ASCII.GetBytes(szData);
    
            int sent = server.Send(byData, SocketFlags.None);
    
            byte[] bytesFrom = new byte[1025];
            //  string bytesSent = server.Send(
            int iRx = server.Receive(bytesFrom);
    
            string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
            String resultchk = dataFromClient.Substring(4, 4).ToString();
            if (resultchk == "0061")
            {
                label2.BackColor = Color.Violet;
                label2.Text = "Torque Data Readed ";
                textBox1.Text = dataFromClient.ToString();
    
                txtcellid.Text = dataFromClient.Substring(22, 4).ToString();
    
                txtchannelid.Text = dataFromClient.Substring(28, 2).ToString();
    
                txtjobid.Text = dataFromClient.Substring(86, 2).ToString();
    
                txtControlorName.Text = dataFromClient.Substring(32, 25).ToString();
    
                txtBatchSize.Text = dataFromClient.Substring(95, 4).ToString();
    
                txtBatchCount.Text = dataFromClient.Substring(101, 4).ToString();
    
                txttighteningstatus.Text = dataFromClient.Substring(107, 1).ToString();
                if (txttighteningstatus.Text.Trim() == "0")
                {
                    txttighteningstatusok.Text = "NOK";
                }
                else
                {
                    txttighteningstatusok.Text = "OK";
                }
    
                txttorquestatus.Text = dataFromClient.Substring(110, 1).ToString();
    
                if (txttorquestatus.Text.Trim() == "0")
                {
                    txttorquestatusok.Text = "Low";
                }
                else if (txttorquestatus.Text.Trim() == "1")
                {
                    txttorquestatusok.Text = "OK";
                }
                else 
                {
                    txttorquestatusok.Text = "High";
                }
    
                txtanglestatus.Text = dataFromClient.Substring(113, 1).ToString();
    
                txttorqueminlimit.Text = dataFromClient.Substring(116, 6).ToString();
    
                txttorquemax.Text = dataFromClient.Substring(124, 6).ToString();
    
                txtfinaltorque.Text = dataFromClient.Substring(132, 6).ToString();
    
    
                txttorque.Text = dataFromClient.Substring(142, 2).ToString() + "." + 
                  dataFromClient.Substring(144, 2).ToString();//dataFromClient.Substring(140,6).ToString()
    
                txtTighteningID.Text = dataFromClient.Substring(221, 10).ToString();
    
    
                String szData3 = "00200062000000000000#";//Nutrunner Communication Start
                byte[] byData3 = Encoding.Default.GetBytes(szData3);//System.Text.Encoding.ASCII.GetBytes(szData);
    
                int sent3 = server.Send(byData3, SocketFlags.None);
            }
        }
        catch (Exception ex)
        {
        }
    }
  9. Disconnect the connection
  10. Check for the connection if it's connected, then disconnect the communication in the detailed code below:

    private void button2_Click(object sender, EventArgs e)
    {
        if (server.Connected == true)
        {
            label2.BackColor = System.Drawing.Color.Red;
            label2.Text = "Not Connected";
            server.Disconnect(true);
            server.Close();
            server.Dispose();
            clears();
        }
    }

Points of Interest

I love to work and play with the HMI (Human Interface Program). I have worked with several HML programs using C# like PLC, sensor programming, and Nutrunner tool communication program. While working with this program I didn’t get the proper guides to achieve the result, but finally I got it to work. I want the end users who read this article to benefit from this program.
