Read OPC VT_CY data

[RasmusVistisen]

How do I read/convert the data type "VT_CY" using the "DataSocket Read.vi"?

Hi Rasmus,

according to Google and Microsoft "VT_CY" denotes a currency value and should contain a string…

When I try reading it as a string it returs an empty value

Hi RasmusVistisen,

Thank you the post. Apologies for the delay in the reponse of the post.

I am unfamilar with the "VT_CY" data type,  but I think it does represent a currency string. How are you trying to pass the data type through the dataSocket read vi? Can you post a vi snippet?

Ive attached examples of how to pass a string through the dataSocket Read.

Hi Dan,

thanks for the reply. I have more or less solved the problem by some reverseengineering. I found a OPC client that could read the data to compare with. I read the data as a variant (think it was 64 bytes....) and looked for the hexadecimal values that gave the right value and converted those. its not pretty, and a little shaky, since i don't know if it will work in all cases.
