Implementace Instrument je jiz komplikovanejsi. Instrument definuje sve Device, prirazuje jim Component a stara se o vycitani udaju z Component.

Instrument s sebou nese i sve vlastni nastaveni (metoda getSettingsService()), ktere je popsano v nasledujici casti.

Instrument je rovnez vazan k ExperimentType, coz je deklarovano v konstruktoru (ExperimentType s sebou nese deklaraci spousty trid a budu se mu venovat az pozdeji).

public class DokuwikiInstrument extends Instrument {
 
	Eurotherm eurotherm = new Eurotherm();
	LabJackT7 labjack = new LabJackT7();
 
	private DoubleValueIntAddrComponent thermometer;
	private DoubleValueIntAddrComponent tempSetPoint;
 
	private IntValueStringAddrComponent counter;
 
	public DokuwikiInstrument() {
		super();
		setDefaultExpType(new DokuwikiExpType());
 
		initEurotherm();
		initLabJack();
	}
 
	private void initEurotherm() {
		List<Component> components = new ArrayList<Component>();
 
		// setting Address = 1; Divisor = 10
		thermometer = new DoubleValueIntAddrComponent(eurotherm, 1, 10);
		thermometer.addGetCondition(new IntervalCondition(0, 1000));
		thermometer.setName("Loop.1.Main.PV");
		thermometer.setDescription("corrected temperature [˚C]");
		setTempCorrectioner();
		components.add(thermometer);
 
		tempSetPoint = new DoubleValueIntAddrComponent(eurotherm, 2, 10);
		tempSetPoint.addGetCondition(new IntervalCondition(0, 600));
		tempSetPoint.addSetCondition(new IntervalCondition(0, 600));
		tempSetPoint.setName("Loop.1.Main.TargetSP");
		tempSetPoint.setDescription("temp setPoint [˚C]");
		components.add(tempSetPoint);
 
		eurotherm.setComponents(components);
		eurotherm.setName("Eurotherm e3508");
		this.addDevice(eurotherm);
	}
 
	private void setTempCorrectioner() {
		DokuwikiInstrumentSettingsService instrumentSS = (DokuwikiInstrumentSettingsService) this.getSettingsService();
		thermometer.setCorrectioner(new Correctioner(instrumentSS.getTempCorrectioner()));
	}
 
	private void initLabJack() {
		List<Component> components = new ArrayList<Component>();
 
		counter = new IntValueStringAddrComponent(labjack, "DIO18_EF_READ_A");
		counter.addGetCondition(new GreaterThanCondition(0.));
		counter.setName("CIO2 counter");
		counter.setDescription("pulse counter");
		components.add(counter);
 
		labjack.setComponents(components);
		labjack.setName("LabJack T7");
		this.addDevice(labjack);
	}
 
 
	public Eurotherm getEurotherm() {
		return eurotherm;
	}
 
	public LabJackT7 getLabjack() {
		return labjack;
	}
 
	public double getTemperature() throws IOException, GetValueException, Exception {
		return thermometer.readValue(true);
	}
 
	public void setSetPoint(double setPoint) throws IOException, SetValueException, Exception {
		tempSetPoint.writeValue(setPoint);
	}
 
	public int getCounter() throws IOException, GetValueException, Exception {
		return counter.readValue(false);
	}
 
	@Override
	public InstrumentSettingsService getSettingsService() {
		return new DokuwikiInstrumentSettingsService(this);
	}
 
	@Override
	public void terminateProcedure() {
		// TODO Auto-generated method stub
	}
 
}

Jak muze byt videt u deklarace jednotlivych Comopnent, kazda Componenta pouziva tridu, ktera definuje, jaky typ hodnoty z adresy jakeho typu tato Componenta vycita.

	private DoubleValueIntAddrComponent thermometer;
	private DoubleValueIntAddrComponent tempSetPoint;
 
	private IntValueStringAddrComponent counter;

Pri inicializaci Device se tyto Componenty deklaruji. Nejzajimavejsi je metoda setTempCorrectioner(), ktera z nastaveni Instrumentu pretahne Correctioner na komponentu thermometer.
