can labview7 express vi's and/or DAQ virtual channel wizard be used with only the tag engine and no add-in boards??

It looks like the express vi's are setup to work with add-in DAQ hardware rather than the tag engine. What I am wondering is if I could take a group of 1000 analog tags and write them to a single binary string memory tag. Then use this single memory tag with the express vi's to capture a single data sample at a time(maybe as a virtual channel). Maybe I would have to turn the data array into a waveform before writing to the memory tag. Are there any examples of using the express vi's with the tag engine??

Hi,

The LabVIEW DSC 7 still supports only the following tags :

Analog ; Discrete ; Discrete Array and String.

The Express VI's are not directly related to the DSC module, they are simplified VI's that allows configuration as opposed to programming (external wiring). A program using the Express VI's can write and read from tags as long as the value falls into the four categories above mentioned.
