Installing a New Version of NI-XNET To Older LabVIEW Can Break I/O Control DialogsNI-XNET (full version) and the NI-XNET Runtime Engine include the four most recent versions of the XNET LabVIEW driver library. If you build an application with a version of LabVIEW that is more than four years old, after you install a new version of NI-XNET your deployable installer will not include support for NI-XNET.
Workaround: Do not install a new version of NI-XNET to use with a version of LabVIEW that is four years old or older.

Sending Multiple Data as Frames on AssignFrameIdRange is not SupportedThe LIN Specification indicates that multiple bits can be sent in a frame. If AssignFrameIdRange is used multiple times in a schedule, some data is lost and random values appear at the end of the
command. The following image compares the data used in the LDF file with the
data imported by NI-XNET.  Workaround: There is currently no known workaround for this issue. |

NI-XNET Component Fails to Load When Added to a LabVIEW ProjectWhen an XNET palette item is added to a blank VI in a
LabVIEW project, a conflict occurs in the project explorer dependency tree. After the project has been saved and closed, the component points to the wrong VI
paths.  Workaround: First create the VI with the XNET content, and only then add it to the project and save the project. |

A PHY can be put into low power mode when a PXIe-8520 link partner is not low-power capableWhen a
PXIe-8520 is configured to disable sleep capability, a paired link partner can
still initiate a TC10 sleep request and enter a low-power sleep state while the
paired PXIe-8520 port remains awake. This behavior differs from the existing
behavior seen with the PXIe-8523, where disabling sleep capability on a port
correctly prevents the paired link partner from entering a sleep state when
both PHYs on the link cannot sleep.
Workaround: Synchronizing
sleep capability states between paired ports should be handled explicitly from
the user application.
