Java 套接字被中断-Modbus-J2Mod

我正在用Java开发一个modbus UDP实现[J2Mod（2.3.4）]。我几乎没有找到有用的文档。我写了一个奴隶，如下所示

它基本上是创建一个UDP从站，并为unitId=0和unitId=1添加processImage。然后它写出数字输入和数字输出

public class Slave {
    private SimpleProcessImage image;
    private ModbusSlave slave;
    public Slave(){
        image = new SimpleProcessImage();
        for (int i = 0; i < 62000; i++) {
            image.addDigitalOut(i, new SimpleDigitalOut(false));
            image.addDigitalIn(i, new SimpleDigitalIn(false));
         }
         (new Timer()).scheduleAtFixedRate(new TimerTask() {
            @Override
            public void run() {
                    read();
            }
        }, 10000, 10000);
        startServer();
    }

private void read() {
        System.out.print("Read In : ");
        for (int i = 0; i < interSize; i++) {
            System.out.print((image.getDigitalIn(i).isSet() ? 1 : 0) + " ");
        }
        System.out.print("Read Out: ");
        for (int i = 0; i < interSize; i++) {
            System.out.print((image.getDigitalOut(i).isSet() ? 1 : 0) + " ");
        }
}
    public void startServer() {
        try {
            slave = ModbusSlaveFactory.createUDPSlave(502);
            slave.addProcessImage(0, image);
            slave.addProcessImage(1, image);
            slave.open();
        } catch (ModbusException e) {
            e.printStackTrace();
        }
    }
}
