I have to connect to OPC DA server from LabVIEW and read more than 400 tags synchronously/asynchronously. I know there is an option with NI DSC module to create LabVIEW OPC client. The problem is I do not want to buy NI DSC license because it has overhead functionality and hence costs a lot.
I am curios if you had an experience to connect OPC DA server without NI DSC from LabVIEW.
In addition to Yair's answer I have found an very useful toolkit here for $295 that provides fast and simple mechanism to connect to OPC servers from LabVIEW. I have tested with trial mode and it seems my problems are solved with this. http://opc-da.com/
