Unable to load/find RTwatchdog.llb

[duelingcats]

I am trying to open Watchdog - RT Engine.vi in the LabVIEW 2015\examples\Real-Time Module\NI Watchdog directory. I am getting a problem where it cannot find a control nammed "Watchdog expiration actions.ctl" when opening the VI. I have LabVIEW 2015 with real time installed along with the device drivers. I can't find where this control is.

When loading, it is searching for:

<vilib>:\RTwatchdog.llb\Watchdog expiration actions.ctl

I opened the project (when working with RT targets and RT code, it is really necessary to use projects):

Watchdog - RT Engine.lvproj

in LabVIEW 2015\examples\Real-Time Module\NI Watchdog directory and was able to open the VI Watchdog - RT Engine.vi from the project. No missing dependencies.

path of RTwatchdog.llb should be

C:\Program Files (x86)\National Instruments\LabVIEW 2015\Targets\NI\RT\vi.lib\RTwatchdog.llb

If it is not there, either it got moved/removed, or RT installation had issue, in which case you would want to force reinstall LabVIEW Real Time.

I did the LabVIEW Real Time repair and it still wasn't there. Do I need to do a full reinstall?

Kelle, thank you! I was looking in a different directory this whole time. The RTwatchdog.llb file is in the directory you specified. The only thing I have remaining now is to find niwd4c.dll. I saw I have other dlls that start with niwd4c, but then contain other characters afterwards. Do you happen to know what package that dll is a part of?

[Kelle]

that dll should be located in

C:\Program Files (x86)\National Instruments\RT Images\NI-Watchdog\15.0

If it is not there, or if you do not have that folder, then you might be missing stuff.  Look at this forum thread too (http://forums.ni.com/t5/LabVIEW/Where-do-I-find-the-library-quot-niwd4c-quot/m-p/3180899).

Force reinstall is different than repair, as it goes through and reinstalls everything.  Repair will not necessarily reinstall items if it already finds that they exist.

Isn't the Watchdog Timer code installed with the Device Drivers?

Hi all,

I have the same issue, I can`t find the RTwatchdog.llb, but the topic in my case it's that I had the library present before installing Labview 2024 Q3.

Could someone explain me how can I do to have RTwatchdog again and  both Labview instalations (Labview 2015 SP1 32bits & Labview 2024 Q3 32bits) , Are them compatible?
