Replied by support on topic .WriteItemValue (method was not found)

The WriteItemValue method still exists. Argument types etc. might have changed, though.

1. Which QuickOPC version are you now using?
2. Which tool/language is your code in?
3. Please post the relevant part of your code.
4. What is the precise error message?

Thank you

.WriteItemValue (method was not found) was created by webprog

We use QuickOPC in a web environment to provide simple web interfaces to devices connected to a Kepserver. Recently we upgraded to a new the latest version and adjusted some old code to point to the new class reference. [Class="OpcLabs.EasyOpc.DataAccess.EasyDAClient"]

it seems something has changed because the .readitemvalue(... works fine but .writeitemvalue(.. reports an error stating that the method was not found. How do I write values back to the OPC server with the new version?

Thanks!
