Programmatically Enumerate and Sort Shared Variables From a Library Using the DSC Module

[charris]

Introduction

This program adapts and uses two previous examples.

Using these examples, it generates and deploys a library of shared variables, then enumerates that library and sorts the variables into separate arrays by data type.

The purpose of the example is to demonstrate the ease of programmatic Shared Variable Engine control and interaction using the LabVIEW Datalogging and Supervisory control module. These tasks would be much more complex and time consuming (or even impossible) without the DSC functionality. Additionally, this method provides for greater application scalability, as it greatly reduces the difficulty in working with large quantities of variables.

Instructions

1. Enter the desired name of the process/library to be generated.
2. Run the VI.

Additional Notes

This VI does not provide sorting for every datatype, but the framework is in place to allow scalability and handling more datatypes. See block diagram comments for further details.
