Sending a boolean to an Android PLC

I was able to establish a connection with the PLC to read data from it. Now there is one problem, and I have to write a method to modify the data from the PLC. To do this, I have to send two values ​​to the PLC: int value and boolean value. I got int value resolved through classes from net.wimpi.modbus package. But when it comes to logical meaning, I have no idea what to do.

If someone had the same problem as I have now, could you please send me a link where I can find a solution or a link to a really good tutorial to solve my problem? Someone posted a couple of links in this question , but he sends me to textbooks that have little to do with communication with PLCs and how to process PLC data.

EDIT

I have established communication with the Modicon M340 controller, and for connection I use the classes of the net.wimpi.modbus package. I made a connection in my code through the ModbusTCPTransactionand classes TCPMasterConnection, and I read the values ​​through the ReadMultipleRegistersRequestand classes ReadMultipleRegistersResponse.

The code I made to connect:

    private InetAddress m_Address;
private ModbusTCPTransaction m_Transaction = null;
private TCPMasterConnection m_Connection = null;

int port = Modbus.DEFAULT_PORT;
private Activity activity;


public ModbusConnection(Activity activity, String ip)
{
    this.activity = activity;

    try {
        m_Address = InetAddress.getByName(ip); 
    } catch (UnknownHostException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } // the slave'saddress
}

public void getTransaction(InetAddress inet) throws Exception
{
    /*Variables for the reading of the PLC data*/
    int port = Modbus.DEFAULT_PORT;

    /*Data initialization for the reading of the PLC data*/
    m_Connection = new TCPMasterConnection(inet);
    m_Connection.setPort(port);
    m_Connection.connect();
    m_Transaction = new ModbusTCPTransaction(m_Connection);
}

{

    ReadMultipleRegistersResponse rRes = null; // the response

    try {

        rReq = new ReadMultipleRegistersRequest(offset, count);
        m_Transaction.setRequest(rReq);
        m_Transaction.execute();
        rRes = (ReadMultipleRegistersResponse) m_Transaction.getResponse();

    } catch (Exception e) {
        e.printStackTrace();
        Log.i("AsyncTask", "doInBackground: Exception");
    }
    return rRes;    
}
