<h1>LabVIEW Simulation Interface Toolkit 3.0.1 Readme</h1>
<p class="Body">March 2006</p>
<p class="Body">The Simulation Interface Toolkit (SIT) 3.0.1 updates <a href="#30">SIT 3.0</a> to support LabVIEW 8.0, the LabVIEW Real-Time Module 8.0, and the LabVIEW FPGA Module 8.0. You also can use SIT 3.0.1 with LabVIEW 7.1.<em>x</em>. However, you cannot install SIT 3.0.1 for both LabVIEW 8.0 and LabVIEW 7.1.<em>x</em>.</p>
<p class="Body">The following list pertains to SIT 3.0.1.</p>
<ul>
<li>When converting a model to a model DLL, you can improve conversion time by excluding signals from virtual blocks. However, if you exclude these signals, you cannot probe these signals unless you add a non-virtual block to the signal. Complete the following steps to exclude signals from virtual blocks.
<ol>
<li>Launch the Simulink application software and load the model you want to convert.</li>
<li>For the MathWorks, Inc. MATLAB® application software release 13, select <strong>Simulation»Simulation parameters</strong> to launch the <strong>Simulation Parameters</strong> dialog box.<br><br>For the MathWorks, Inc. MATLAB® application software release 14, select <strong>Simulation»Configuration Parameters</strong> to launch the <strong>Configuration Parameters</strong> dialog box.</li>
<li>Click the <strong>Real-Time Workshop</strong> tab. </li>
<li>Click the <strong>Browse</strong> button to launch the <strong>System Target File Browser</strong> dialog box. </li>
<li>Select <strong>nidll.tlc—NI Real-Time Target</strong> from the list.</li>
<li>Click the <strong>OK</strong> button.</li>
<li>For the MathWorks, Inc. MATLAB® application software release 13, enter <span id="Monospace">nidll.tlc -aNiDisableVirtualBlockMap=1</span> in the <strong>System target file</strong> text box.<br><br>For the MathWorks, Inc. MATLAB® application software release 14, enter <span id="Monospace">-aNiDisableVirtualBlockMap=1</span> in the <strong>TLC options</strong> text box.</li>
</ol></li>
<li>If you are using SIT 3.0.1 with LabVIEW 7.1.1f<em>x</em>, you cannot view custom FPGA VIs. <strong>Workaround:</strong> After you click the <strong>Browse</strong> button in the <strong>Add FPGA Device</strong> dialog box, select <strong>View All</strong> from the <strong>File Type</strong> drop-down list. If you are using a pre-defined FPGA VI that ships with SIT 3.0.1, you must rename the VI on disk to <span id="Monospace">sitfpga <em><device></em> 7_1_1_f<em>x</em> <em>devicetype</em>.vi</span>, where <span id="Monospace"><em><device></em></span> is the FPGA device, <span id="Monospace"><em>x</em></span> is the LabVIEW update number, and <span id="Monospace"><em>devicetype</em></span> is <em>master</em> or <em>slave</em>. </li>
<li>If you are running a simulation on the NI PXI-8146, you must install the LabVIEW Real-Time Module to the NI PXI-8146 before installing the Simulation Interface Toolkit 3.0.1.</li>
<li>If you open a host VI you saved in SIT 3.0, the <strong>SIT Connection Manager</strong> dialog box loads slowly the first time you launch this dialog box. The load time reduces the next time you launch this dialog box.</li>
<li>If you create a mapping using the <strong>SIT Connection Manager</strong> dialog box and then click the <strong>Cancel</strong> button, the new mapping is retained.</li>
<li>SIT 3.0.1 includes two VIs that enable datalogging for a custom host VI. These VIs, SIT FinishLogging VI and SIT Log Continuously VI, are located in the <span id="Monospace">labview\vi.lib\addons\Simulation Interface\driverblocks\</span> directory.</li>
<li>If you use the <strong>Project Explorer</strong> window to deploy a driver VI to a real-time target, you must run that VI before the host VI can connect to it. You must complete the following steps before running the driver VI.
<ol>
<li>Right-click the real-time (RT) target in the <strong>Project Explorer</strong> window and select <strong>Properties</strong> from the shortcut menu.</li>
<li>Select <strong>VI Server: Configuration</strong> in the <strong>Category</strong> list.</li>
<li>Place a checkmark in the <strong>TCP/IP</strong> checkbox.</li>
<li>Select <strong>VI Server: Machine Access</strong> in the <strong>Category</strong> list.</li>
<li>Click the <strong>Add</strong> button, and enter the IP address of the host computer in the <strong>Machine name/address</strong> text box.</li>
<li>Select <strong>VI Server: Exported VIs</strong> in the <strong>Category</strong> list.</li>
<li>Click the <strong>Add</strong> button, and enter the path and name of the driver VI in the <strong>Exported VI</strong> text box.</li>
<li>Click the <strong>OK</strong> button.</li>
</ol>
<br><br>If you build the model DLL again after running the simulation, you must remove the driver VI from memory before running simulation again.
<br><br>If you use the <strong>SIT Connection Manager</strong> dialog box to create and deploy a driver VI, you do not need to use the <strong>Project Explorer</strong> window.</li>
<li>If you run a driver VI on a non-RT target and want to connect to the driver VI by using a networked PC, you must run the driver VI before attempting to connect to it from the networked PC. You also must complete the following steps on the PC running the driver VI.
<ol>
<li>Launch LabVIEW and open the driver VI.</li>
<li>Select <strong>Tools»Options</strong> from the pull-down menu.</li>
<li>Select <strong>VI Server: Configuration</strong> in the <strong>Category</strong> list.</li>
<li>Place a checkmark in the <strong>TCP/IP</strong> checkbox.</li>
<li>Select <strong>VI Server: Machine Access</strong> in the <strong>Category</strong> list.</li>
<li>Click the <strong>Add</strong> button, and enter the IP address of the networked PC in the <strong>Machine name/address</strong> text box.</li>
<li>Select <strong>VI Server: Exported VIs</strong> in the <strong>Category</strong> list.</li>
<li>Click the <strong>Add</strong> button, and enter the path and name of the driver VI in the <strong>Exported VI</strong> text box.</li>
<li>Click the <strong>OK</strong> button.</li>
</ol></li>
<li>If you are running a multirate simulation using an NI FPGA device and a lower-priority task finishes late, this late finish forces the driver VI to report an overrun, which halts the simulation. This behavior occurs regardless of whether the <strong>Halt Simulation on Any Task Overrun</strong> checkbox contains a checkmark.</li>
</ul>
