Contoh Mengakses PLC Dengan C# - I

 


Programmable Logic Controller, disingkat PLC merupakan peralatan elektronik yang dibangun dari mikroprosesor untuk memonitor keadaan dari peralatan input untuk kemudian di analisa sesuai dengan kebutuhan perencana (programmer) untuk mengontrol keadaan output. Sinyal input diberikan kedalam input card.
Ada 2 jenis input card, yaitu :
  • Analog input card
  • Digital input card

Contoh untuk mengakses PLC :

1. Connect to PLC

using PLCcom;

public class myTestClass

{

    //declare the Device 

    private PLCcomDevice Device;

    private void btnConnect_Click(object sender, System.EventArgs e)

    {

        //create TCP_ISO_Device instance from PLCcomDevice

        Device = new TCP_ISO_Device("192.168.1.2", 0, 2, ePLCType.S7_300_400_compatibel);

        //or create MPI_Device instance from PLCcomDevice 

        //Device = new MPI_Device("COM2", 0, 2, eBaudrate.b38400, eSpeed.Speed187k, ePLCType.S7_300_400_compatibel); 

        //or create PPI_Device instance from PLCcomDevice 

        //Device = new PPI_Device("COM2", 0, 2, eBaudrate.b9600, ePLCType.S7_200_compatibel);

 

        authentication.User = "";   //Enter User here

        authentication.Serial = ""; //Enter Serial here

         

        Device.Connecttimeout = 1000;

        Device.Readtimeout = 2000;

        ConnectResult res = Device.Connect();

 

        MessageBox.Show(res.Message);

    }

}


2. Disconnect from PLC

Untuk memutuskan koneksi ke PLC cukup 1 baris perintah : Device.DisConnect();


3. Automatic connect to PLC

using PLCcom;

public class myTestClass

{

    //declare the Device 

    private PLCcomDevice Device;

    private void btnConnect_Click(object sender, System.EventArgs e)

    {

        //create TCP_ISO_Device instance from PLCcomDevice

        Device = new TCP_ISO_Device("192.168.1.2", 0, 2, ePLCType.S7_300_400_compatibel);

        //or create MPI_Device instance from PLCcomDevice 

        //Device = new MPI_Device("COM2", 0, 2, eBaudrate.b38400, eSpeed.Speed187k, ePLCType.S7_300_400_compatibel); 

        //or create PPI_Device instance from PLCcomDevice 

        //Device = new PPI_Device("COM2", 0, 2, eBaudrate.b9600, ePLCType.S7_200_compatibel);

 

        authentication.User = "";

        authentication.Serial = "";

 

        //Set auto connect

        //The connection is opened automatically when it is needed. If after the expiry of the given period, no more requests are sent, the connection is automatically closed.

        Device.setAutoConnect(true, 10000);

    }

}


4. Simple reading data from PLC

using System;

using PLCcom;

using System.Windows.Forms;

namespace CodeDokuCSharp

{

    class newClass

    {

        PLCcomDevice Device;

 

        private void btnRead_Click(object sender, EventArgs e)

        {

            //declare a ReadRequest object

            //set the request parameters

            //read 10 Bytes from DB100

            ReadDataRequest myReadRequest = new ReadDataRequest(eRegion.DataBlock, 100, 0, eDataType.BYTE, 10);

 

            //read from device

            ReadDataResult res = Device.ReadData(myReadRequest);

 

            //evaluate results

            txtMessage.Text = res.Message;

            if (res.Quality == OperationResult.eQuality.GOOD)

            {

                foreach (byte b in (byte[])res.GetValues())

                {

                    txtResult.Text += b.ToString() + Environment.NewLine;

                }

                MessageBox.Show("OK", "Result:", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

            else

            {

                MessageBox.Show(res.Message, "Result:", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

        }

    }

}

Contoh Mengakses PLC Dengan Java - I

 

Programmable Logic Controller, disingkat PLC merupakan peralatan elektronik yang dibangun dari mikroprosesor untuk memonitor keadaan dari peralatan input untuk kemudian di analisa sesuai dengan kebutuhan perencana (programmer) untuk mengontrol keadaan output. Sinyal input diberikan kedalam input card.
Ada 2 jenis input card, yaitu :
  • Analog input card
  • Digital input card

Contoh untuk mengakses PLC :

1. Connect to PLC

import PLCCom.*;
import javax.swing.JOptionPane;
 
public class NewClass {
