Hello,
here a part of code :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace AutomationSenseSpace
{
class SiemensPLC
{
public static libnodave.daveOSserialType fds; //declaration connection type
public static libnodave.daveInterface di; //declaration of connection interface
public static libnodave.daveConnection dc; //declaration of connection
public static int res; // déclaration of res value for fonction return
public static byte plcValue; //declaration of plcValue to Read from PLC it's a byte in this case
public static int memoryRes; //declaratiob of memoryRes memoryRes for ReadBytes function return
public static byte[] memoryBuffer = new byte[10]; //declaration of an byte array with 10 bytes value

// Let's code the connect function

public static void connectTo()

{
fds.rfd = libnodave.openSocket(102, "192.168.56.1"); //connect to PLC with IP address
fds.wfd = fds.rfd;
di = new libnodave.daveInterface(fds, "IF1", 0, libnodave.daveProtoISOTCP, libnodave.daveSpeed187k);
res = di.initAdapter();
dc = new libnodave.daveConnection(di, 0, 0, 2);
res = dc.connectPLC();
memoryRes = dc.readBytes(libnodave.daveFlags, 0, 0, 1, memoryBuffer); //read a buffer of 1 byte and put it on memoryBuffer variable
plcValue = memoryBuffer[0]; //put memoryBuffer byte value on plcValue variable
dc.disconnectPLC(); // disconnect PLC
di.disconnectAdapter(); //disconnect Adapter
libnodave.closePort(fds.rfd); // close connection


}

}
}

Hello Vilson Arantes,

That's normal your application freeze when you run it because you must put the library named libnodave.dll into the bin folder like this picture

Hello Yassine12,
Libnodave library is only for Siemens PLC.You must use DF1 library for Allen Bradley PLC
