This is not related to the trial version.

And, we would throw an exception if the server had returned an error. So it looks more like a server issue.

1. Which OPC server are you using please?
2. What is the data type of the item on the server?
3. What is the data type of the 'value' you are passing in?
4. Is the server local or remote to the client?
5. Does it happen with all Write-s, or just some/sometimes?
6. Do reads work well?
7. Do subscriptions work well?
8. Please try to perform the same Write not using your code, but with the .NET-based Demo application that comes with the product - does it work then?

Thank you

There is no exception being thrown but the new value is not reflected on OPC server.

Not Able to write tag on software toolbox top server v4 was created by sushant1459
We are currently using TOP server v4 and v5 along with ADVOSOL client for connectivity from C# application. We are facing some issue with compatibility to new .Net version with ADVOSOL. Now to evaluate other options we started to use EasyOpc.DataAccess but we are facing an issue in writing tags. We are currently using the demo version of the DLLs. Please help me identify the issue. Is this due to the demo version.

I am using following code to write the tag.

easyDAClient.WriteItemValue(MachineName, ServerClass, tagName, value);

Thanks in advance
