Utgard. Unable to write the value of the tag on the OPC Server Codesys.

[Alexander Kuleshov]

Having difficulty write the tag on the OPC Server Codesys, although with other servers (Matrikon, Kepware) do not have such problems.

I chose specifically code fragment taken from your example (https://openscada.atlassian.net/wiki/display/OP/HowToStartWithUtgard):

public class Main 

{

 

    public static void main(String[] args) throws Exception 

    {

 

        final ConnectionInformation ci = new ConnectionInformation();

 

        ci.setHost("myhost");

        ci.setDomain("OPCHOST");

        ci.setUser("user");

        ci.setPassword("password");

        //ci.setProgId("SWToolbox.TOPServer.V5");

        ci.setClsid("7904C302-AC19-11d4-9E1E-00105A4AB1C6"); // if ProgId is not working, try it using the Clsid instead

        final String itemId = "PLC1:.arm_GKS_HA_03";

        // create a new server

        final Server server = new Server(ci, Executors.newSingleThreadScheduledExecutor());

        try 

        {

            // connect to server

            server.connect();

            // add sync access, poll every 500 ms

            final AccessBase access = new SyncAccess(server, 5000);

            access.addItem(itemId, new DataCallback() 

            {

                public void changed(Item item, ItemState state) 

                {

                try

{

System.out.println("Changed tag: ["+state+"\t, "+state.getValue().getObject());

} catch (JIException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}

                }

            });

 

            // Add a new group

            final Group group = server.addGroup("test");

            // Add a new item to the group

            final Item item = group.addItem(itemId);

 

            // start reading

            access.bind();

 

            // add a thread for writing a value every 3 seconds

            ScheduledExecutorService writeThread = Executors.newSingleThreadScheduledExecutor();

            //final AtomicInteger i = new AtomicInteger(0);

            writeThread.scheduleWithFixedDelay(new Runnable() 

            {

                public void run() {

                    //final JIVariant value = new JIVariant(i.incrementAndGet());

                final JIVariant value = new JIVariant(new Random().nextBoolean());

                    try 

                    {

                        System.out.println("Write value: "+value.getObject());

                        item.write(value);

                    } catch (JIException e) {

                        e.printStackTrace();

                    }

                }

            }, 5, 3, TimeUnit.SECONDS);

 

            // wait a little bit

            Thread.sleep(20 * 1000);

            writeThread.shutdownNow();

            // stop reading

            access.unbind();

        } catch (final JIException e) {

            System.out.println(String.format("%08X: %s", e.getErrorCode(), server.getErrorMessage(e.getErrorCode())));

        }

    }

}

As a result, I get an unspecified error:

The result comes from your OPC server.

So the question is, why does it return with 0x8004005?

Do you have any idea why I dont get this error when I use the Matrikon-Client for write the value of the tag?

Sorry, no.

Capturing ethernet traffic in both cases and comparing it could be usefull.

On the other hand it could be an error in codesys implementation, may be enabling logging in codesys could help also.
