Thank you! Attached is a snapshot of the current code from the end user. I do not think it is being used properly, as "myargument" is not referred to again in the provided code.

Thank you!

Here is the code which the end user is using to set the autocondition to false. Is this correct?

UAMonitoredItemArguments myargument = newUAMonitoredItemArguments();
myargument.AutoConditionRefresh = false;

Initially, my thought was that this was in the incorrect location, but even after moving where this is placed within the code multiple times, we are still seeing the BadNotImplemented. Based on an additional Wireshark that was provided, it does seem that we are getting this for the same call as before.

At this point, I suspect we are doing something wrong with how we are setting the attribute, but I admit that coding knowledge is not my strongest suit.

Thank you very much for the clarification!

I requested a new capture and have attached what the customer provided to this response. Please let me know if you need anything else from us!

My hope is that we are just overlooking something simple here.

Hello!

We have a customer who is working on creating an OPC UA Alarms and Events client to connect with a server that has little documentation.

When using the SubscribeEvent method, this customer receives "OPC UA service result - {BadNotImplemented}. Requested operation is not implemented."

He is able to subscribe to the same event in UAExpert, so we ran a Wireshark to compare the two calls. The only difference I found was that we sent different values within the Array of Variant in the InputArugments field (image attached.)

After doing some digging, I could not determine what this variant is or whether we can change what variant we are sending, and I was hoping you could help shine some light on this.

As always, thank you in advance!
