[milo-dev] Reply: Write node value error

["george.ray" <george.ray@xxxxxxxxxx>]

I modified WriteExample.java, and wrote node value through KEP Server.

In KEP Server the node data type is Word, value is 2500, I want to modify the value to 3000.

This is the souce code :

@Override
public void run(OpcUaClient client, CompletableFuture<OpcUaClient> future) throws Exception {
    // synchronous connect
    client.connect().get();
    List<NodeId> nodeIds = ImmutableList.of(new NodeId(2, "ChannelTest.DeviceTest.Tag190"));
    Variant v = new Variant((short)3000);
    DataValue dv = new DataValue(v, null, null);
    CompletableFuture<StatusCode> f = client.writeValue(nodeIds.get(0), dv);
    StatusCode status = f.get();

    if (status.isGood()) {
        logger.info("Wrote '{}' to nodeId={} success", v, nodeIds.get(0));
    }
    else
        logger.info("Wrote '{}' to nodeId={} failed", v, nodeIds.get(0));

    future.complete(client);
}

How to set values type in Eclipse Milo when writing Node?

If you post your code I could tell you more, but OPC UA requires that you write values of the correct type for the Node you're writing to.

Hi，

I am testing write node value function by WriteExample, but getting “StatusCode{name=Bad_TypeMismatch, value=0x80740000, quality=bad}” error.

What's the reseason of this issue? Maybe the value type is error, but I don't known how to set the type when writing value.

Thanks!

Best regards,

George Ray
