Hi,
Your code looks ok to me, ie. passing 3000 as short to Variant.
But it might be that kepware doesn’t like passing null statuscode,
try “new DataValue(v, StatusCode.GOOD, null)” instead.

Subject: [milo-dev] Reply: Write node value error
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.
@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);
}

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.

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.
