The following items are known issues in LabVIEW 2011 and 2011 SP1 sorted by Category.
| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| Toolkit - Desktop Execution Trace Toolkit | ||||||
| 127647 Return | Save All Traces asks for a file name but does not use it When you right-click an application instance and select "Save All Traces", or select File»Save All Traces, the file name that is entered is not used. The files are instead named according to the date and time the traces were started. File name format: month_day_year _ hour_minute_second_fractionalsecond.ttd. For example, a traced started on January 1, 1904 at 01:22:33.444444 would be saved as 1_1_1904 _ 01_22_33_444444.ttd Workaround: Use Windows Explorer to manually rename the files once it's saved.
| |||||
| 144704 Return | DETT can record "DeQueue Element Awake" - "Awoke with Data" events in the wrong thread The code that records the particular event ("DeQueue Element Awake" - "Awoke with Data") can happen in such a way that we record it in the thread that enqueues the data. It does not mean that the primitive is actually waking up in the same thread. Workaround: N/A
| |||||
| 224367 Return | Desktop Execution Trace Toolkit does not trance a LabVIEW built DLL called from LabVIEW Because of the way LabVIEW calls DLLs built in the same or different versions, DETT cannot trace a LabVIEW built DLL. Workaround: N/A
| |||||
| 281507 Return | Desktop Execution Trace Toolkit 2010 Does Not Highlight the Traced Items Under LabVIEW 2010 Japanese Double-clicking a trace item does not highlight the item in question in the block diagram. Instead Error Code 1510 is returned. Workaround: N/A
| |||||
| 328834 Return | DETT doesn't correctly trace application if launched outside of LabVIEW Tools » Profile menu If Desktop Execution Trace toolkit is launched from Windows Explorer, and attempts to trace the execution of an instance of LabVIEW that doesn't have the default VI Server port (3364), no events will appear in the event log. Workaround: Launch DETT via LabVIEW's Tools » Profile » Trace Execution menu or change LabVIEW to use the default VI Server port.
| |||||
| Toolkit - Other | ||||||
| 177698 Return | [PID and Fuzzy Logic] Center of Sums, Center of Maximum, Mean of Maximum may give NaN result The Center of Sums, Center of Maximum, Mean of Maximum functions give a NaN result for an output variable if this variable contains a Gaussian or a Sigmoid membership function. Workaround: N/A
| |||||
| 125072 Return | [SIT] 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 | [SIT] 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 | [SIT] 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] 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/
| |||||
| 294984 Return | System Identification Toolkit Returns non-sensible error when input sizes are different SI Estimate Partially Known State-Space Model VI can incorrectly report error -20002 even when the input sequences are in fact the same size. Instead the error should be -41528 "The matrix exponential calculation overflowed." Workaround: N/A
| |||||
| 325714 Return | [MASM] Unexpected behaviour when using FFT VIs or Linear Algebra VIs in a timed loop On a desktop computer, unexpected results are returned on first iteration when FFT VIs or Linear Algebra VIs are placed inside of a timed loop. Workaround: Use a while loop instead.
| |||||
| 358379 Return | [MASM] Incorrect results are returned if FFT VIs or Linear Algebra VIs are used in a timed loop On a desktop computer, an incorrect result is returned on first iteration when FFT VIs or Linear Algebra VIs are placed inside of a timed loop on LabVIEW 2011 SP1 32-bit. Workaround: Use a while loop instead.
| |||||
| Toolkit - Report Generation | ||||||
| 200345 Return | The "Append Table to Report" VI displays incorrect values in MS Word 2010 and Report Generation Toolkit 2010. Using the "Append Table to Report" VI to add strings of Cyrillic font to a table in an MS Word report results in gibberish being added to the report. Workaround: N/A
| |||||
| 188911 Return | Control image alignment incorrect when "new report page" VI is used When using the "append control image to report" VI, the alignment of some images is ignored when the "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: Place 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) 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 RGT 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.
| |||||
| 313610 Return | Excel ActiveX methods lead to an error in Report Generation Toolkit 2011. When the examples are opened the VI has a broken run arrow and the error list says the SubVI's are not executable. SubVI's contain invoke nodes that are calling Active X methods that are not linked properly. Workaround: Right click on reference wire into broken invoke node and select Create » Create method for 'broken invoke node' to recreate the invoke node. Then rewire and VI is fixed.
| |||||
| 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.
