How to know the type of the object ?

[Valter Henrique]

Hi everyone,
i was thinking how to know if the object is 'analog output' or 'analog input' ? the same to binary type.

in Test2.java you can :

    private static void getObjectList(LocalDevice localDevice, String ip, int port, int deviceId) throws Exception {
        InetSocketAddress addr = new InetSocketAddress(InetAddress.getByName(ip), port);
        ReadPropertyRequest read = new ReadPropertyRequest(new ObjectIdentifier(ObjectType.device, deviceId), PropertyIdentifier.objectList);
        ReadPropertyAck ack = (ReadPropertyAck) localDevice.send(addr, null, 1476, Segmentation.segmentedBoth, read);

        System.out.println("IP: " + ip);
        SequenceOf<ObjectIdentifier> oids = (SequenceOf<ObjectIdentifier>) ack.getValue();
        for (ObjectIdentifier oid : oids)
            System.out.println("    " + oid);
    }

But if i try get only the analogOutput like this:

    private static void getAnalogOutputList(LocalDevice localDevice, String ip, int port, int deviceId) throws Exception {
        InetSocketAddress addr = new InetSocketAddress(InetAddress.getByName(ip), port);
        ReadPropertyRequest read = new ReadPropertyRequest(new ObjectIdentifier(ObjectType.analogOutput, deviceId), PropertyIdentifier.presentValue);
        ReadPropertyAck ack = (ReadPropertyAck) localDevice.send(addr, null, 1476, Segmentation.segmentedBoth, read);
        
        System.out.println("IP: " + ip);
        SequenceOf<ObjectIdentifier> oids = (SequenceOf<ObjectIdentifier>) ack.getValue();
        for (ObjectIdentifier oid : oids) {
            System.out.println("    " + oid);
        }
    }

Launch a exception:

ErrorAPDU(choice=12, errorClass=Object, errorCode=Unknown object)

Could anyone help me with this ?

you still need to ask for complete objectList
then only show analogOutput

	private static void getObjectList(LocalDevice localDevice, String ip, int port, int deviceId) throws Exception 
	{  
		InetSocketAddress addr = new InetSocketAddress(InetAddress.getByName(ip), port);  
		ReadPropertyRequest read = new ReadPropertyRequest(new ObjectIdentifier(ObjectType.device, deviceId), PropertyIdentifier.objectList);  
		ReadPropertyAck ack = (ReadPropertyAck) localDevice.send(addr, null, 1476, Segmentation.segmentedBoth, read);  

		System.out.println("IP: " + ip);  
		SequenceOf<ObjectIdentifier> oids = (SequenceOf<ObjectIdentifier>) ack.getValue();  
		for (ObjectIdentifier oid : oids)  
		{
			if(oid.getObjectType().intValue() == ObjectType.analogOutput.intValue())
			{
				System.out.println("    " + oid);
			}
		}
	}

sorry taking so long to reply friend. (I was involved in another project, but now returning to bacnet4j )

I try what you suggest but it just told me the value of the binary and the analog, which is :

Object type || value
Device : 8
Analog Value : 2
Binary Value : 5

What I need is a little more specific, how to know the int value of a binary input for example ?
