| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| Toolkit - Advanced Signal Processing | ||||||
| 431453 Return | TSA Principal Component Analysis (Array).vi does not correctly calculate the covariance matrix when the "unified?" input is sent to False. N/A Workaround: Use the TSA Covariance (Array).vi which is located at "vi.lib\addons\Time Series Analysis\Statistical Analysis.llb\TSA Covariance (Array).vi"
| |||||
| Toolkit - Database Connectivity | ||||||
| 347325 Return | DB Tools Insert Data.vi does not write dates correctly when OS language is set to French date format When Windows language format is set to French with the short date to dd/MM/yyyy, the DB Tools Insert Data.vi writes incorrect values to database files. Workaround: Convert timestamp data into strings before inserting into the database with the DB Tools Insert Data.vi.
| |||||
| 389996 Return | Error 1 Returned from DB Tools Insert Data.vi Error will be returned when writing array data to MS Access database, and column values are provided despite the database already having column values. Workaround: N/A
| |||||
| Toolkit - Other | ||||||
| 356420 Return | Robotics Wizard cannot load a manifest file in a folder with a Chinese character in the name Robotics Wizard cannot load a manifest file in a folder with a Chinese character in the name Workaround: Move the manifest file to a new location
| |||||
| 412822 Return | Issues with the Biomedical Workbench when you downgrade the Biomedical Toolkit from 2013 to 2012 If you downgrade the Biomedical Toolkit from the 2013 release to the 2012 release, the Biomedical Workbench reports an error, and the positions of the application icons are incorrect. Workaround: Delete the following files from the Biomedical Toolkit\Workbench\data directory to solve this problem: Applications.dat, IconsData.dat, and SeekBtnData.dat. This restores the Biomedical Workbench to the default setting. However, the Biomedical Workbench loses all application icons that you added to the Biomedical Workbench.
| |||||
| 510649 Return | Changing an indicator into a constant within a Control & Simulation Loop breaks the VI If you have an indicator within a Control & Simulation loop, changing that specific indicator into a constant can break the VI. Workaround: Create a new constant instead of changing an indicator into a constant.
| |||||
| Toolkit - PID and Fuzzy Logic | ||||||
| 514789 Return | Autotuning PID Online.VI Example Reads Proportional Gain 'NaN' with the Relay Technique. When running the Autotuning PID Online.vi example, with the Relay Technique the "Tuned PID gains" output of proportional gain (Kc) shows "NaN" when the program believes tuning is completed by flashing "tuning completed?". Workaround: Tune the individual terms first. Start by first tuning for P until the response is stable. Then continue to tune by switching to PI. Lastly, repeat the process for PID.
| |||||
| Toolkit - Report Generation | ||||||
| 188911 Return | Control image alignment incorrect when "new report page" VI is used When using Append Control Image to Report.vi, the alignment of some images are ignored when New Report Page.vi is used between appended images. This problem only exists with Office 2007. Other versions - Office 2003 and Office 2010 do not exhibit this behavior. Workaround: Use a New Report Line.vi between appending the image and the New Page.vi
| |||||
| 249185 Return | Unable to Create Report from Macro-Enabled Word or Excel Template (.dotm file) Macro-Enabled Word or Excel templates (.dotm) file types are not handled by the Word and Excel implementations of the New Report.vi Workaround: Add "mtod" to the case containing Word_Create_Document.vi to properly handle these templates. This case structure can be found within the NI_Word:lvclass:new report subVI.vi
| |||||
| 312071 Return | Error 7 when using Report Generation Toolkit VIs in a DLL By default Report Generation Toolkit VI's are compiled into the DLL, but can't be executed from within the DLL. Workaround: The DLL will run correctly if you include the Report Generation toolkit lvclass dependencies in a separate support directory and specify that they are always included in a data directory.
| |||||
| 382455 Return | Microsoft Excel Template named cell range font size is overwritten When appending cell data to named cell ranges from Microsoft Excel Templates, font size is always size 10pt. Workaround: Use Excel Set Cell Font.vi to manually set the desired font for each named range.
| |||||
| 391394 Return | Dates are Reversed by Excel Easy Table.vi on Non-US Languages The month and day are reversed when exporting data to Excel for languages other than US-English. For example 03/02/2013 (3rd of February 2013) in LabVIEW is exported as 02/03/2013 and considered as 2nd of March 2013 by Excel. Workaround: After investigations, we found that the problem was coming from NI_ReportGenerationToolkit.lvlib:Excel_Insert_Table.vi Indeed in this VI, there are three followed Range property nodes for "Value2". When desactivated the last two, the issue is not here anymore. However, when using this workaround, there are then problem with colors (??).
| |||||
| 463584 Return | Append Horizontal Line to Report VI generates incorrect HTML code with width units in percent and decimal separator is set to "," Workaround: Set ". "as decimal separator, or change the string format in the vi to '%.;%f%%'
| |||||
| 472835 Return | The Save Report to File.vi requires the "report file path" terminal to be wired, but is not set as a required input The VI will return Error -41003 when running the VI if the path is not wired or empty. This requirement is enforced in the VI itself, so it will not break the run arrow. Workaround: Wire the file path of the report to the VI.
| |||||
| Toolkit - Simulation Interface | ||||||
| 125072 Return | Applications using only the SIT Scheduler VI will hang An application just using the SIT Scheduler VI will hang on the second iteration when calling the model DLL. Workaround: The SIT Model Update VI needs to be called directly after the SIT Scheduler VI. Or replace the SIT Schedule VI with the SIT Take Model Time Step VI
| |||||
| 257100 Return | Deleting an indicator in SIT 2010 VI breaks VI and does not recompile automatically Deleting an indicator from a compiled VI results in a broken error because of a blank event structure inside the SIT portion of the block diagram. Opening the SIT Connection Manager and clicking OK to recompile the SIT portion of the block diagram does not recompile the code and the VI remains broken. Workaround: Manually change the mapping in the Connection Manager and then click OK.
| |||||
| 276747 Return | Large arrays are grayed out and will not map to a Simulink model using the Simulation Interface Toolkit The Simulation Interface Toolkit cannot map an array larger than 10 elements to a Simulink model. If an array larger than 10 elements is mapped in the SIT Connection Manager, the array will become grayed out on the front panel. Workaround: Break up larger arrays into several smaller arrays with 10 or less elements. Re-combine the elements in Simulink by using the "Mux" block.
| |||||
| 301408 Return | SIT fails to create correct path for replay file on PXI controllers Error 14112 when using a replay file with SIT with some PXI controls. 8101 and 8108 models have shown this behavior. Workaround: Change Filename = "/1.tdms" to Filename = "1.tdms" in the ini file located at / replay config/
| |||||
| 367752 Return | Model with Custom S-Function Returns Null Pointer Exception on Pharlap OS If structs are defined inside a function on a Pharlap target the model will return a null pointer exception. Workaround: Structs should be defined in static memory when using a Pharlap target
| |||||
| Toolkit - Unit Test Framework | ||||||
| 120941 Return | Code Coverage analysis is not supported on LabVIEW Real-Time The Unit Test Framework Toolkit cannot measure code coverage on real-time (RT) targets. The result will always be zero. Workaround: N/A
| |||||
| 160115 Return | lvtest file can not be added to the LabVIEW project if it is in multi-level libraries If lvtest file is in a library, and the library is the child of another library, the lvtest file can not be added to the LabVIEW project by dragging & dropping from disk to the project or by using context menu "Add » Files..." Workaround: N/A
| |||||
| 175831 Return | Cannot create a test for an XY Graph If the VI has a XY Graph control as input or output, creating a test for this VI will fail, usually with the error "The following control name is not unique". You will get an error saying that the control name is not unique. Workaround: N/A
| |||||
| 171553 Return | File load conflict after dragging multiple LV Classes to another context You will get loading conflict for lvtest files if you open a project which has multiple LV Classes and those classes have lvtest files of the same name. Loading any VI will also be very slow if you have this loading conflict in your project. Workaround: Rename the lvtest files to different names. Or remove those lvtest files from the project and re-add them.
| |||||
| 420795 Return | When creating a custom LV project template with the Unit Test Framework .lvtest file, the new project will overwrite the original template when saving instead of creating a new instance with new files. Workaround: N/A
| |||||
| 466818 Return | Error 1527 will occur when running the example "Programmatically Run Tests from Projects.vi" referencing the example project "LV Class.lvproj." Workaround: 1. Open LV Class.lvproj 2. Open by double clicking in Windows Explorer "Programmatically Run Tests from Projects.vi" (Now the VI will be in the LV Class.lvproj LabVIEW instance) 3. Modify "Programmatically Run Tests from Projects.vi" to run LV Class.lvproj 4. Run the VI
| |||||
| 475037 Return | Enabling loop iteration parallelism in For Loops results lower code coverage than expected A For Loop configured for parallelism is incorrectly counted as an uncovered diagram when calculating code coverage Workaround: Turn off parallelism or set the for loop to "Allow debugging" for the code coverage test
| |||||
| 471993 Return | Cannot create Unit Test for VI with control connected to the terminal and inside a tab control This result in an error: LabVIEW: Type Mismatch: Object cannot be cast into the specified type. Workaround: If possible, do not have a control connected to the VI's terminal and inside a tab control.
