Latest NI LabVIEW DSC Module Features and DemosWhat's New in LabVIEW Datalogging and Supervisory Control (DSC)Support for Windows XP EmbeddedWith Windows XP Embedded support, you can now deploy HMI applications based on LabVIEW DSC with features such as alarming, logging, and trending to touch panel computers. Communicate with and display information from headless devices such as NI Compact FieldPoint, CompactRIO, and Compact Vision System programmable automation controllers (PACs). Navigation ControlsMinimize development time by using the new navigation controls to sequence and jump to different VIs without having to write any code. Tag APIUse the Tag API to build high-channel-count applications quickly. The tag API provides functions to access live and historical data and alarms. This high-level dynamic shared variable API provides the ability to write DSC applications using tag names instead of shared variable URLs. Automatic Shared Variable Deployment from ExecutablesBuild executables with NI Application Builder, which automatically absorbs dependent shared variable libraries and deploys them on execution. This new feature in the application builder also offers the ability to choose other shared variables libraries that need to be deployed on the execution of the built executable.

National Instruments LabVIEW 8 introduced the new LabVIEW shared variable, a unified API for communicating data among VIs executing on the same local machine or across a network. The NI LabVIEW DSC Module extends the data services portion of the LabVIEW shared variable by adding configuration-based logging, alarming, scaling, and more.
Previously, LabVIEW DSC users had to develop custom polling logic for applications that required programmatic response to alarm conditions or other system events. With LabVIEW DSC, you can register alarms and events as cases in the LabVIEW event structure to quickly implement event-driven applications without any separate polling.
Security is a vital aspect of application development, particularly for distributed applications. LabVIEW DSC features a number of enhanced security features, including domain-based security. Now you can configure unique security settings for individuals and user groups based on log-in domains. Additionally, security settings are network-based, so you can configure security for a single server and distribute those settings to all networked clients.
The new LabVIEW shared variable makes it easier than ever to integrate applications based on LabVIEW into your existing architecture. The LabVIEW shared variable engine — the feature that manages all of the shared variable communication — is an OPC 2.x and 3.0 client. Additionally, the LabVIEW DSC Module adds OPC 2.x and 3.0 server support and a Modbus TCP I/O server, so you can read and write to OPC- and Modbus TCP-compliant hardware.
