Quick Start

EtherNet/IP Example

EtherNetIpClientConfig config = EtherNetIpClientConfig.builder("10.20.4.57")
        .setSerialNumber(0x00)
        .setVendorId(0x00)
        .setTimeout(Duration.ofSeconds(2))
        .build();

EtherNetIpClient client = new EtherNetIpClient(config);

client.connect().get();

client.listIdentity().whenComplete((li, ex) -> {
    if (li != null) {
        li.getIdentity().ifPresent(id -> {
            System.out.println("productName=" + id.getProductName());
            System.out.println("revisionMajor=" + id.getRevisionMajor());
            System.out.println("revisionMinor=" + id.getRevisionMinor());
        });
    } else {
        ex.printStackTrace();
    }
});

client.disconnect().get();

// Call this before application / JVM shutdown
EtherNetIpShared.releaseSharedResources();

CIP Service Example

EtherNetIpClientConfig config = EtherNetIpClientConfig.builder("10.20.4.57")
        .setSerialNumber(0x00)
        .setVendorId(0x00)
        .setTimeout(Duration.ofSeconds(2))
        .build();

// backplane, slot 0
PaddedEPath connectionPath = new PaddedEPath(
        new PortSegment(1, new byte[]{(byte) 0}));

CipClient client = new CipClient(config, connectionPath);

client.connect().get();

GetAttributeListService service = new GetAttributeListService(
        new PaddedEPath(new ClassId(0x01), new InstanceId(0x01)),
        new int[]{4},
        new int[]{2}
);

client.invokeUnconnected(service).whenComplete((as, ex) -> {
    if (as != null) {
        try {
            ByteBuf data = as[0].getData();
            int major = data.readUnsignedByte();
            int minor = data.readUnsignedByte();

            System.out.println(String.format("firmware v%s.%s", major, minor));
        } catch (Throwable t) {
            t.printStackTrace();
        } finally {
            Arrays.stream(as).forEach(a -> ReferenceCountUtil.release(a.getData()));
        }
    } else {
        ex.printStackTrace();
    }
});

client.disconnect().get();

// Call this before application / JVM shutdown
EtherNetIpShared.releaseSharedResources();
