Updated Mar 10, 2020

Overview

This document contains the NI-TimeSync known issues that were discovered before and since the release of the NI-TimeSync 15.5. Not every issue known to NI will appear on this list; it is intended to only show the severe and common issues.

Known Issues by Date

The following items are known issues in NI-TimeSync 15.5 sorted by Date.

246727—Changing the priority in NI MAX or the Web-based Configuration & Monitoring Utility may leave ni-rt.ini in an inconsistent state.
477434—The NI-TimeSync Software-Based 1588 plug-in fails to synchronize properly when used with a secondary network adapter on PharLap ETS and VxWorks targets.
493251—Running an ARM-based Linux Real-Time target as a 1588 master may degrade synchronization
652137—Disabling/re-enabling primary ethernet ports in NI-MAX or in the commnad line will cause synchronization issues.



IDKnown Issue
246727

Return		Changing the priority in NI MAX or the Web-based Configuration & Monitoring Utility may leave ni-rt.ini in an inconsistent state.

Workaround: N/A

Reported Version: 1.1  Resolved Version: N/A  Added: 08/03/2015
477434

Return		The NI-TimeSync Software-Based 1588 plug-in fails to synchronize properly when used with a secondary network adapter on PharLap ETS and VxWorks targets.

Workaround: National Instruments recommends that you only use the primary network adapter when using the NI-TimeSync Software-Based 1588 plug-in.

Reported Version: 14.0  Resolved Version: N/A  Added: 08/03/2015
493251

Return		Running an ARM-based Linux Real-Time target as a 1588 master may degrade synchronization.

Workaround: National Instruments recommends that you only use ARM-based targets running NI Linux Real-Time as 1588 slaves. ARM-based targets running NI Linux Real-Time are slave only by default.

Reported Version: 14.0  Resolved Version: N/A  Added: 08/03/2015
652137

Return		Disabling/re-enabling an ethernet port on a cRIO-903x (Sync) or an IC-317x in NI-MAX or in the command line will cause synchronization issues unless the system is rebooted. Issues might appear as undefined static time offsets, asynchronous FPGA times or the Time Source I/O reporting “None”. Never disable eth0 on the cRIO-9035x (Sync) or eth1 on IC-317x, this will cause all synchronization to halt.

Workaround: N/A

Reported Version: 17.0  Resolved Version: N/A  Added: 07/07/2017
