This document contains the LabVIEW Communications System Design Suite 2.1 known issues that were discovered before and since the release of LabVIEW Communications System Design Suite 2.1. Not every issue known to NI will appear on this list; it is intended to only show the severe and more common issues that can be encountered.
The following items are known issues in LabVIEW Communications System Design Suite 2.1 sorted by Date.
| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| 704824 Return | The Xilinx IP Generator fails to launch after clicking the "Configure Xilinx IP" button on some builds of Windows 10 (version 1709) Clicking the "Configure Xilinx IP" button on the Item tab of a Xilinx CORE Generator IP Node fails to launch the Xilinx IP Generator on some builds of Windows 10 (version 1709). Workaround: Update to a newer build of Windows 10 (version 1709).

| 703930 Return | It is not possible to use variable sized array controls in Optimized FPGA VIs As a result of the Known Issue tracked by ID 703080 all FPGA subVIs in a Library that are separate from the library that contains the top-level VI must be marked as exported. When a VI in an Optimized FPGA Library is marked as exported it is treated as a top-level VI and top-level Optimized FPGA VIs don't support variable sized array controls. Workaround: N/A
| |||||
| 703080 Return | FPGA compilations fail when dependencies in a Library are not exported When a Bitfile Application contains a VI that references an exported VI from a Library Document and that VI references a third VI that is not marked for export then an error is incorrectly thrown during compilation. VIs in a Library are marked for export by default. Workaround: Select the export checkbox for all affected VIs in the Library Document.

| 688821 Return | Installing LabVIEW Communications 2.1 on a machine with an existing installation of LabVIEW Communications 2.0 prevents the older version of the software from communicating with Real-time targets. Installing LabVIEW Communications 2.1 on a machine with an existing installation of LabVIEW Communications 2.0 prevents the older version of the software from communicating with Real-time targets. This is a result of LabVIEW Communications 2.1 upgrading software components used for system discovery and communication, rendering these components incompatible with LabVIEW Communications 2.0. Workaround: Maintain a separate PC for use only with LabVIEW Communications 2.0. Alternatively, fully uninstall both versions of LabVIEW Communications and related shared components from your system and then reinstall LabVIEW Communications 2.0.

| 706310 Return | Shared Library Interface documents that use Type Definitions as the type for function parameters are broken following conversion. Opening a LabVIEW Communications 2.0 project in LabVIEW Communications 2.1 that contains a Shared Library Interface document using Type Definitions as the type for function parameters are broken following conversion. Workaround: After conversion click on each affected function parameter and on the Item tab click the GType dropdown and select the correct GType from the list.

| 706319 Return | Some PXIe controllers mistakenly appear as Real-Time Compatible in SystemDesigner. The PXIe-8840, PXIe-8840 Quad-Core and PXIe-8821 mistakenly appear in SystemDesigner as supported Real-Time controllers. These controllers are not supported as Real-Time controllers at this time. Workaround: Use a PXIe-8880 or PXIe-8135 if a Real-Time controller is needed.

| 707042 Return | Any project containing a MathScript Node that had the 'Show Label' checkbox selected will fail to migrate properly. Migration fails when opening a LabVIEW Communications 2.0 project in LabVIEW Communications 2.1 that contains a MathScript Node that had the 'Show Label' checkbox selected. The failure will occur even if the 'Show Label' checkbox was later deselected. The Conversion dialog may report "Converting source files to components failed with unknown error" and when you attempt to open the VI that contained the MathScript Node an error is thrown stating that "The source file format is invalid." Workaround: In a backup copy of the LabVIEW Communications 2.0 project open the VI containing the MathScript Node, drop a new MathScript Node, copy the text from the old node into the new node, and delete the old node. Then rewire as necessary, save the VI and attempt the conversion process in LabVIEW Communications 2.1 again.
