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 2009 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.
The following sections describe the new features in the DSC Module.
Use the NI Distributed System Manager to create and monitor shared variables, network variables, processes, and I/O servers. You also can use the System Manager to manage security and aliases. In LabVIEW, select Tools»Distributed System Manager to launch the System Manager.
The DSC Module includes the following enhancements to the System Manager:
The DSC Module includes the following enhancements to custom I/O servers.
When you build an application that includes custom I/O servers, the LabVIEW Application Builder detects and copies all dependent custom I/O servers to the LVDSC folder inside the same directory as the build. When you deploy the built application to the target computer, LabVIEW distributes the custom I/O servers to the target computer automatically. You no longer have to copy the dependent custom I/O servers to the target computer.
LabVIEW upgrades dependent custom I/O servers to the latest version automatically when you deploy an application in the DSC Module or the DSC Module Run-Time System.
|Note The automatic upgrade feature supports only custom I/O servers configured in LabVIEW 8.5 or later.|
The System Manager displays status and error information about the custom I/O servers that you deploy to the SVE. Use the System Manager to monitor and debug custom I/O servers.
EPICS, or the Experimental Physics and Industrial Control System, is a set of open-source software tools you can use to develop large, distributed control systems. EPICS systems use the Channel Access (CA) network protocol to pass data between EPICS client and EPICS servers, also known as input/output controllers (IOCs). The CA network protocol is an Ethernet-based protocol.
The DSC Module acts as an EPICS server and an EPICS client. You can create EPICS Server I/O servers in the DSC Module to publish local and remote shared variables and I/O data to an EPICS network. Use EPICS Client I/O servers or third-party EPICS clients to monitor and update these shared variables.
In the Project Explorer window, right-click a target, such as the My Computer target, and select New»I/O Server from the shortcut menu. In the Create New I/O Server dialog box, select EPICS Server and click the Continue button to create an EPICS Server I/O server.
The DSC Module includes the following new VIs.
The Tags palette includes the new Utility palette with the following new VIs and functions:
You can distribute a built application to a Touch Panel target by installing the DSC Module Run-Time System on the Touch Panel device.
Use the navigation controls located on the System and Modern palettes to navigate through multiple front panels in an application. Navigation controls include the Previous Button, Next Button, and Jump Button controls.
The DSC Module includes the following new examples:
