ID | Known Issue | |||||
---|---|---|---|---|---|---|
899451 Return | NI-Digital does not validate Bit Order for Capture Engine reconfiguration If multiple capture waveforms are used within a single session, the NI-Digital driver should validate Sample Width, Pins, Waveform Type (Serial/Parallel), and Bit Order (MSB/LSB) to determine if the Capture Engine must be reconfigured. The Bit Order setting is not being validated. This means that if the two capture waveform configurations differ in Bit Order and the other 3 settings are consistent, then no reconfiguration will take place and the data for one of the waveforms will be returned with incorrect bit order.. Workaround: Configure all waveforms to be a consistent Bit Order and reorder in software as necessary. Alternatively, close and create a new NI-Digital session between waveforms with settings that differ only in Bit Order.

715045 Return | Frequency measurements are returned in ascending order of channels regardless of the channel list or pin list parameter. Frequency counter measurements will incorrectly return data in ascending channel order regardless of the channel list or the pin list. If the provided channel list or pin list input to the frequency measure function is not in ascending channel order, then the application will get incorrect results. Workaround: Install NI-Digital Pattern Driver and Digital Pattern Editor patch 17.0.4, 17.1.2, or 18.0.1.

716093 Return | Capture memory streaming may return incorrect samples when fetching more than a million samples per pattern burst. If less than one million capture samples are fetched in a single pattern burst, then the application is unaffected. Otherwise, incorrect samples may be returned. Workaround: Install NI-Digital Pattern Driver and Digital Pattern Editor patch 17.0.4, 17.1.2, or 18.0.1.
| |||||
692863 Return | The NI-Digital driver is not installing policy files that redirect between major/minor versions when using the .NET API. The lack of policy files means that code built against an older version of NI-Digital will have to be recompiled before it can be used on a system that only has the newer version. Workaround: If the source is available for the project that references NI-Digital, change the reference in the source and rebuild it. Additionally, this issue is resolved in the NI-Digital 17.0.3 patch and NI-Digital 18.0 and newer.
| |||||
681944 Return | Certain programming sequences can result in internal bus contention that, over time, could damage the instrument. Contention can occur after using source memory on the PXIe-6570 internal bus. Over time this can cause damage to the instrument. Workaround: Install NI-Digital Patch 16.0.2 or 17.0.2 to resolve this issue. Additionally, any future version of NI-Digital post NI-Digital 17.5 will resolve this issue.

673746 Return | HRAM may return an incomplete set of failures if HRAM is configured to use pretrigger samples and capture failures only If the HRAM settings within the Digital Pattern Editor are configured to have the Cycles to Capture to Failures Only and the Pretrigger Cycles is greater than 0, the failures captured may be different than the requested failures. All returned failures are actual failures, but some of the failures that were requested may not be returned. Workaround: Setting the Cycles to Capture to All will guarantee the correct samples are captured..

577343 Return | Loading large patterns in a 32-bit process runs out of memory As a result of limited system memory in a 32-bit process, loading a large pattern in a 32-bit process might fail. Workaround: Split large patterns loaded in a 32-bit process into patterns that are small enough to fit into the available system memory.

672536 Return | NI Example Finder does not filter for PXIe-6570 hardware Using hardware filtering in the NI Example Finder does not return any examples that support the PXIe-6570. Workaround: To find PXIe-6570 examples, use the NI Example Finder search feature with "6570" as the keyword or browse the task structure under Hardware Input and Output»Modular Instruments»NI-Digital Pattern Driver.
