Getting NTP option on RT Controller

[TunaFish]

Hi all,

I'm trying to sync my real time controller to a NTP server. 

I followed all the instructions on the following below link, but wasn't able to get the time sync to work.

https://forums.ni.com/t5/Sync-Labs/TimeSync-for-SNTP-Getting-Started/gpm-p/3543825

The problem is when I installed timesync, the instructions told me to modify the file "/ni-rt/system/ni-timesync/ni-timesync-sntp.ini" which is nowhere to be found in the ni-timesync folder. I was able to find the ptp ini file but not the sntp. Do I have to create the ini file myself or should it have been created when I installed timesync program into my real time controller?

Any help would be useful! Thanks!

are you talking about the linux-based boxes (eg. cRIO-9064) ?

Hi

First thing that comes to mind is that your controller might not running VxWorks or Phar Lap OS. 

Which cRIO are you using? 

BTW here is a KB that can help you figure out what OS is running on your cRIO

No idea about pharlap's strange partial win32 clone (if one really looks for win32 clones - go for reactos), but if they still even requires reboot for trivial things like timezone changes, I wouldn't expect anything useful related to time synchronization.

Here are a couple of options if your OS is Linux RT

Some people have also had success by using this program to set the time.

time/clock handling is a can of worms:
