Issue Details

What is the difference between the Datalogging and Supervisory Control (DSC) >> Engine Control VIs >> Variables & I/O Servers VIs and the Data Communication VIs and Functions >> Shared Variable Node, VI, and Functions? Both seem to work with Shared Variables.

Solution

The primary difference is the Shared Variable VIs in the Data Communication palette are used to connect to and read/write from Shared Variables, whereas the Shared Variable VIs in the DSC/Engine Control palettes are used to create, configure, and delete shared variables.
