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. |

A Hardware Error Occurs After a CPU Spike on the CompactRIO ControllerA CPU spike on a cRIO-906x controller running an NI-XNET session can cause the error "A hardware error has occurred" to appear, and leave the XNET module in an unrecoverable state that requires a reboot of the controller. Workaround: Mitigate CPU usage on the CompactRIO controller. Other CompactRIO platforms seem not to be affected. |

LDF File is Not Loaded if Min/Max Value of Scaling is NegativeThe XNET Database Editor throws an error if the user tries to load a LIN description file (LDF) in which <physical_value> contains a negative integer for either <min_value> or <max_value>. The LIN specification states that min_value and max_value must be in range of 0 to 65535. Workaround: Use any ASCII text editor to edit the LDF file and manually change the minimum or maximum value of a scaling to zero (or any positive integer). |

Database with Japanese Characters in File Name Cannot Be Loaded on Japanese OSThe NI-XNET Database Editor running on a Japanese OS is unable to load a database file that contains Japanese characters in its file name. Workaround: On Japanese OS, use the old version of the NI-XNET Database Editor to open and edit the database or to create an alias that does not use Japanese characters.
In the new Database Editor, select File > Open Alias to load the database using the alias you created. |

Signal to CAN Frame Conversion Does Not Set Extended FlagCAN frames use arbitration identifiers that can be either standard or extended formats. In a Conversion Session, when a signal is converted to a CAN frame that uses an extended ID in the database, the extended flag is not being set
in the frame data.
Workaround: Programmatically set the extended? flag to True after the signal is converted by reading it from the database.
