The LabVIEW Datalogging and Supervisory Control (DSC) Module extends the LabVIEW graphical development environment with additional functionality for the rapid development of distributed measurement, control, and high-channel-count monitoring applications.
The DSC Module also enhances the LabVIEW shared variable. Use the shared variable to access and pass data among VIs and devices on the local computer and across a network. A shared variable can represent a value or an I/O point. With the DSC Module, you can log data automatically; add alarming, scaling, and security to the shared variable; and configure the shared variable programmatically.
The DSC Module also enhances the NI Distributed System Manager. You can use the System Manager to monitor, configure, and acknowledge alarms. You also can use the System Manager to monitor and acknowledge events.
To use the System Manager, launch LabVIEW and select Tools»Distributed System Manager.
The DSC Module also provides tools for graphing historical or real-time trends, enhancing the security of front panels, and writing custom I/O servers. You can read or write to OLE for Process Control (OPC) connections, programmable logic controllers (PLCs), or custom I/O servers that you write. The DSC Module provides solutions for supervisory control of a wide variety of distributed systems using graphical LabVIEW programming.
