This document contains the SystemLink EAR known issues that were discovered before and since the release of the SystemLink EAR. 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 SystemLink Early Access Release sorted by Date.
| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| 572618 Return | Deploying a LabVIEW RT startup application through SystemLink will abort any currently running LabVIEW RT application When deploying a LabVIEW RT startup application with SystemLink to a managed system, any LabVIEW RT application that is currently running on the system will be aborted. This could lead to failures in the application. Workaround:
| |||||
| 626469 Return | Downloading multiple files from the File Viewer will only download one file in Internet Explorer 11 When selecting multiple files in the File Viewer and clicking Download, only one file will be downloaded. Workaround: Download each file individually, or use a different supported browser.
| |||||
| 633805 Return | Installing SystemLink Server will overwrite any existing RabbitMQ configuration already installed If SystemLink Server is installed on a system that has an existing installation of RabbitMQ, SystemLink will overwrite the existing RabbitMQ configuration. Workaround:
| |||||
| 613649 Return | Skyline Service Manager occasionally fails to start The Skyline Service Manager service can sometimes fail to start on boot, which will cause other dependent services to fail. SystemLink web applications will not load properly when a system is in this state. Workaround: Reboot your system, or manually start the Skyline Service Manager.
| |||||
| 642024 Return | Cannot set time using 24-hour format in Time Settings application Trying to change the time to 24-hour time format (e.g. 22:45) in the Time Settings view will display a red error box around the Time text field, and Save will be disabled. Workaround: Clear the Time text field first, then enter the time in 24-hour format. This will convert the time from 24-hour format to 12-hour format.
| |||||
| 643384 Return | NI Web Server cannot host NI SystemLink Web Application on system with only IPv6 enabled If a system only has IPv6 enabled and no IPv4 address, remote clients will not be able to access the NI SystemLink Web Application. Workaround:
| |||||
| 644770 Return | NI System Config Init/Close breaks the Skyline data APIs on subsequent interactive runs with LabVIEW RT If a Linux RT target is added to a LabVIEW project and you either Connect or Deploy a VI to that target, Skyline APIs on your host will return error -251021: AMQP error: Failed to create SSL socket. This will also occur in an application that uses both the System Configuration and Skyline APIs on a Linux RT target. The error will be returned from the Skyline APIs on the second run of the application unless the target has been restarted in between runs. Workaround: Restart LabVIEW to fix the error in your host VIs. Restart the Linux RT target to fix the error in an application where VIs using both System Configuration and the Skyline APIs are deployed to the target. Adding a HTTP Get VI from the HTTP Client palette with any URL to an application containing the Skyline VIs will prevent this error from returning.
| |||||
| 644771 Return | An application containing Scan Engine IO Variables will return error -65536 if the application is deployed to a system multiple times without restarting If you deploy an RT application containing Scan Engine IO Variables from SystemLink to a system without restarting, the IO Variable will return error -65536 after the 4th deployment of that application. Error -65536: Unable to communicate with the module. Reinsert the module and check connections. If the chassis is in FPGA Interface programming mode, make sure you have opened an FPGA reference to a bitfile or FPGA VI with Scan Interface support for the module you are trying to access using the Scan Interface. Workaround: Restart the system.
| |||||
| 650859 Return | Aborting a LabVIEW application that uses Skyline APIs can hang for up to 2 minutes A LabVIEW application using the Skyline APIs can take up to 2 minutes to abort if the system cannot connect to the SystemLink Server. Workaround:
| |||||
| 652482 Return | SystemLink applications may not work correctly if the SystemLink Server's hostname or IP address changes across reboot SystemLink applications may return errors if the hostname or IP address of the SystemLink Server changes across reboot. Workaround: Reboot your SystemLink Server a second time.

|---|---|---|---|---|---|---|
| Functions, VIs, and Express VIs | ||||||
| 644770 Return | Skyline APIs can return Error -251021 after connecting to a Linux RT system in LabVIEW or when used in an application that also uses System Configuration API on Linux RT If a Linux RT target is added to a LabVIEW project and you either Connect or Deploy a VI to that target, Skyline APIs on your host will return error -251021: AMQP error: Failed to create SSL socket. This will also occur in an application that uses both the System Configuration and Skyline APIs on a Linux RT target.
