Hello,
I need to implement a program that is listening to a the barcode value change of the Cognex DM8700DX Scanner. I’m able to read the current value of the barcode in the scanner but polling is not an option for my customer.
So I figured out I need to use an OpenForwardRequest for this. But my code gets an exception when trying to decode the response. Can you please tell what I’m doing wrong.
That’s what my code looks like:

EtherNetIpClientConfig config = EtherNetIpClientConfig.builder("169.254.126.143")
		        .setSerialNumber(0x00)
		        .setVendorId(0x00)
		        .setTimeout(Duration.ofSeconds(5))
		        .build();
                PaddedEPath connectionPath = new PaddedEPath(new PortSegment(1, new byte[]{(byte) 0}));

		CipClient client = new CipClient(config, connectionPath);

		try {
			client.connect().get();
			
            int classId = 0x79;  
            int instanceId = 1;  

    		PaddedEPath servicePath = new PaddedEPath(
    				new LogicalSegment.ClassId(classId),
    				new LogicalSegment.InstanceId(instanceId),
    				new LogicalSegment.AttributeId(0x10)
    	            );
            
            NetworkConnectionParameters parameters = new NetworkConnectionParameters(
                    1, //1 connection ?
                    NetworkConnectionParameters.SizeType.Variable,
                    NetworkConnectionParameters.Priority.Low,
                    NetworkConnectionParameters.ConnectionType.PointToPoint,
                    false);
            
            ForwardOpenRequest request = new ForwardOpenRequest(
                    Duration.ofSeconds(15), // Connection timeout
                    0x10000001,  // O->T (Originator to Target) Connection ID
                    0x10000002,  // T->O (Target to Originator) Connection ID
                    new Random().nextInt(),
                    config.getVendorId(),
                    config.getSerialNumber(),
                    0x01, // Connection Timeout Multiplier
                    servicePath,
                    Duration.ofMillis(500), // O->T Requested Packet Interval (RPI)
                    parameters, // O->T Parameters
                    Duration.ofMillis(500), // T->O Requested Packet Interval (RPI)
                    parameters, // T->O Parameters
                    0xA3 // Transport Class and Trigger (Cyclic updates)
            );
            
            ForwardOpenService service = new ForwardOpenService(request);

            CompletableFuture<CipConnection> future = new CompletableFuture<>();
            //Get connection from pool
            client.sendUnconnectedData(service::encodeRequest).whenComplete((b, ex) -> {
                if (b != null) {
                    try {
                        ForwardOpenResponse response = service.decodeResponse(b);
                        
                        CipConnectionPool.CipConnection connection = new CipConnectionPool.CipConnection(
                        		Duration.ofSeconds(15).toNanos(),
                                response.getO2tConnectionId(),
                                response.getT2oConnectionId(),
                                response.getConnectionSerialNumber(),
                                response.getOriginatorVendorId(),
                                response.getOriginatorSerialNumber());

                        ReferenceCountUtil.release(response.getApplicationReply());

                        System.out.println("Connected to forward open");

                        future.complete(connection);
                    } catch (CipResponseException | CipService.PartialResponseException e) {
                        future.completeExceptionally(e);
                        e.printStackTrace();
                    } finally {
                        ReferenceCountUtil.release(b);
                    }
                } else {
                    future.completeExceptionally(ex);
                    ex.printStackTrace();
                }
            });
            

        } catch (Exception ex) {
            ex.printStackTrace();
        }

This is the link to the object model of the scanner.
This is the link describes the implicit messaging of the scanner

Thank you in advance
Kind regards

status=0x01 [connection failure] , additional=[0x011C]

I believe the extended response code for 0x011C is "Transport Class Not Supported"

Thank you. But what does it mean and where in the code is the mistake?

I think the "Transport Class and Trigger" parameter should be 0x01, not 0xA3.

But even if this works you're still very much on your own after that. The library only supports Class 3 (explicit messaging).

You'll need a copy of the EtherNet/IP spec and a healthy understanding of Class 1 to get any further I think.
