Issue Details

I need to read values from a list of Shared Variables, which is returned by Get Shared Variable List VI from DSC Module, but Programmatical Shared Variable functions are not compatible with Network Variable (BV Tag) type.

Solution

When a shared variable is deployed, you can retrieve it's value by creating Variable Identifier URL and reading using Shared Variable programmatical access functions. Name and DataType of a Shared Variable can be get from a corresponding Property Node. This is illustrated below.
