How to know TSN is synchronizing?

Highlighted

Hi all,

 

I have a TSN setup with a cRIO-9045 and cRIO-9040 and after 1 day they get out of sync. Is there a (preferably out of the box and easy) way to double check the synchronisation? On both cRIO-9045 and 9040 there is an NTP daemon running which is synchronizing to the same host machine. Is the combination TSN and NTP surely not conflicting?

 

Thanks!

 

Greets,

Filip.

Please review the following Table:

*Only needed if you need to control a TSN cDAQ from a cRIO (sync).

For cRIO-904x series, the minimum required software is the Software stack 2018, Therefore as you are using cRIO 904x, you need to use at least LabVIEW 2018.

Hi guys, I was digging further in this problem here. And it seems that NTP and the NI-Timesync are unable to work together (as I read in some NI official document). This is very problematic for me as I really need both. The two CompactRIOs need to be perfectly in sync with TSN for the acquisition. The master timebase needs to be the timebase of the company's NTP. Is there a way to tell NI-TimeSync that he needs to use the NTP clock as master timebase and then have all the others follow this NTP clock? 

 

FIY. I couldn't find anything wrong with the software stack. (see screenshots in attachment)

 

I also posted this question in the specific TSN group.
