Read single values from an array tag in an OPC Server

[Jorge_C]

Hi!

We are trying to work with an OPC server with some array tags defined. We can access the array tags perfectly.

If you request a single value from that OPC server (through an OPC client like Wonderware, Ifix, Control Maestro (Wizcon), WinCC, etc….), the OPC server sends a timestamp with the time in which that value was acquired. I have confirmed that there's no way to request single values from an array tag (neither with DSC, nor with DataSocket).

I don't know how hard to develop would this feature be, but I think it would be great.

Regards!!
