Additional Information
The LabVIEW executable does not automatically deploy the shared variables to the Shared Variable Engine (SVE). As a result, you will have to configure the executable to deploy the variables in the Build Specifications, or deploy them programmatically.
The NI DSC Module provides the OPC Client I/O servers that connect to each OPC tag using the OPC DA standard. The SVE provides a
Publish-Subscribe-Protocol (PSP) URL for each OPC tag that other Shared Variables can bind to by enabling aliasing. Once you deploy the Shared Variables in the SVE and the Shared Variables receive values, LabVIEW can easily read and write to the Shared Variables using a VI.
