Refer to the LabVIEW Datalogging and Supervisory Control Module Release and Upgrade Notes for information about system requirements and installation instructions, a complete list of new features and changes, and compatibility and upgrade issues you might encounter when you use the LabVIEW 2013 Datalogging and Supervisory Control (DSC) Module.

Refer to the readme_DSC.html file in the labview\readme directory for a partial list of bugs fixed.

Supervisory Control and Data Acquisition System Sample Project

The Supervisory Control and Data Acquisition System sample project implements supervisory control and data acquisition (SCADA) for a simulated CompactRIO and PLC-based system. This sample project provides a scalable architecture for building systems with a large number of I/O points.

Access this sample project by selecting File»Create Project in LabVIEW.

New VIs

  • Register Server VI—Use the Register Server VI to register the OPC UA server with the UA Local Discovery Server (LDS). This VI is located on the OPC UA Server palette.
  • Unregister Server VI—Use the Unregister Server VI to unregister the OPC UA server with the UA Local Discovery Server (LDS). This VI is located on the OPC UA Server palette.

Behavior Changes

The DSC Module introduces the following behavior changes.

Variables & I/O Servers VIs

The following VIs on the Variables & I/O Servers palette include the new reset when disabled? input which specifies whether to reset the value you specify to the initial state when using this VI to disable a property.

SharedVariableIO Properties

You can use the SharedVariableIO properties without enabling the Enabled property.

In the DSC Module 2012 or earlier, when you disable the Enabled property, LabVIEW resets the value you specify for the SharedVariableIO properties to the initial state. In the DSC Module 2013, when you disable the Enabled property, LabVIEW retains the value you specify for the SharedVariableIO properties.
