Example 1 with ModbusUDPListener

use of net.wimpi.modbus.net.ModbusUDPListener in project openhab1-addons by openhab.

the class UDPSlaveTest method main.

public static void main(String[] args) {
    ModbusUDPListener listener = null;
    SimpleProcessImage spi = null;
    int port = Modbus.DEFAULT_PORT;
    try {
        if (args != null && args.length == 1) {
            port = Integer.parseInt(args[0]);
        }
        System.out.println("jModbus Modbus/UDP Slave v0.1");
        // 1. Prepare a process image
        spi = new SimpleProcessImage();
        spi.addDigitalOut(new SimpleDigitalOut(true));

        ModbusCoupler.getReference().setMaster(false);
        ModbusCoupler.getReference().setUnitID(15);
        // 2. Setup and start listener
        listener = new ModbusUDPListener();
        listener.setPort(port);
        listener.start();
    } catch (Exception ex) {
        ex.printStackTrace();
