real-time 9.0 startup delay

Starting with the real-time module for LabView 9.0 (2009) VIs deployed

to the RT target have a delay of up to 10 seconds before they are actually

executing.  This is quite annoying especially during development. Under LabView 8.6

I did not observe this issue. What could be causing this?

What kind of target are you using? I'm using multiple cRIO with LV2009 and i didn't experience a delay compared to 8.6.

Do you have more details about the code? Is the delay after the code is deployed or before?

My target is a PC running Interval Zeros ETS.

 

The delay occurs after deployment and only if the

VI was changed, e.g. redeployment without any

changes does not produce a delay.

 

I attached a minimal VI derived from one of the DAQmx

examples, which reproduces the delay.

The shared variable "recorded_data_io" uses a RT FIFO

for 1D double arrays containing 200 elements. 

 

Best regards

I don't think that we're supporting ETS RT OS. Can you run your VIs there directly? I would recommend you to use our LabVIEW RT Operating System (based on Pharlab).

Well maybe this was a misunderstanding. 

 

I'm talking about the RT OS shipped by National Instruments with

the RT Module 9.0.

 

The OS is still ETS formerly sold by Pharlap and now Interval Zero.

The deployment delays are encountered by all the members of our working group.

So this is certainly not a specific hardware-related problem of the host/target computer.

Yet, we are all using Windows XP as the host OS. Did nobody else observe similar

delays in their RT setup?
