The Control Design and Simulation Module has the following requirements:
You can run the LabVIEW Control Design and Simulation Module installer on the following operating systems:
The LabVIEW Control Design and Simulation Module installer does not support Windows 2000/NT/Me/98/95 or the Windows Server non-R2 editions.
The LabVIEW Control Design and Simulation Module on Mac OS X and Linux does not support the following features:
The LabVIEW 2010 Control Design and Simulation Module incorporates the following new features and changes.
When you use subsystems on a simulation or block diagram, you can configure those subsystems to execute only when enabled or triggered. An enabled subsystem is one that executes when a Boolean input to the subsystem receives a TRUE value. A triggered subsystem is one that executes when an input signal to the subsystem crosses 0 or an offset from 0 that you specify. The same subsystem can be both enabled and triggered, and you can specify the behavior of individual outputs of the subsystem when that subsystem does not execute.
To configure enabling or triggering for a subsystem, double-click the subsystem to display the Subsystem Configuration dialog box. Select Execution Control from the Parameters list and use the options under Parameter Information to configure the basic execution behavior of the subsystem. Select individual outputs from the Parameters list to configure the behavior of those outputs when the subsystem does not execute.
Note: The Simulation Model Converter also supports the conversion of your .mdl files that contain enabled and triggered subsystems.
In previous versions of the LabVIEW Control Design and Simulation Module, some users experienced slow load times for simulation diagrams. The LabVIEW 2010 Control Design and Simulation Module improve load times for simulation diagrams.
The following table lists new keyboard shortcuts you can use to display the front panel and block diagram of a simulation subsystem.
Note: The <Ctrl> key in these shortcuts corresponds to the (Mac OS X) <Command> key.
| Keyboard Shortcut | Description |
|---|---|
| Ctrl-double-click | Displays the block diagram of the subsystem. |
| Shift-double-click | Displays the front panel of the subsystem. |
You can use the Implicit Systems functions to solve differential algebraic equations (DAEs) on a simulation diagram or within a Control & Simulation Loop. These functions enable you to use DAEs in building a simulation. Previous versions of the Control Design and Simulation module supported only ordinary differential equation (ODE) solvers. Navigate to Control Design & Simulation»Simulation»Implicit Systems on the Functions palette to access the following new functions:
Note: You must select the BDF solver in the Configure Simulation Parameters dialog box to use these functions.
In previous versions of the LabVIEW Control Design and Simulation Module, you could not save a VI that contained a Control & Simulation Loop for a previous version of LabVIEW. In the LabVIEW 2010 Control Design and Simulation Module, you can save VIs that contain a Control & Simulation Loop for LabVIEW 2009. You cannot save these VIs for LabVIEW versions prior to 2009.
The Simulation Model Converter converts your .mdl files that contain enabled and triggered subsystems and configures the resulting subsystems in LabVIEW. Select Tools»Control Design and Simulation»Simulation Model Converter to launch the Simulation Model Converter dialog box and convert your .mdl files.
In previous versions of the LabVIEW Control Design and Simulation Module, the Simulation Model Converter did not support the conversion of statecharts developed with The MathWorks, Inc. Stateflow® application software. In the LabVIEW 2010 Control Design and Simulation Module, the Simulation Model Converter converts statecharts developed with The MathWorks, Inc. Stateflow® application software into statecharts usable within the LabVIEW Statechart Module.
Note: To convert statecharts developed with The MathWorks, Inc. Stateflow® application software to statecharts usable within the LabVIEW Statechart Module, you must install the LabVIEW Statechart Module. Visit the National Instruments Web site for more information about the LabVIEW Statechart Module.
