ni_tagger_lv_write

[woully]

Hello,

i try to exchange values between 2 labview applications with a shared variable. Sometimes, the error "Ni_tagger_lv_Write -1950679023 Communication to server has been killed" appears.

The variable is configured as network variable.

Both applications can read/write this shared variable. Sometimes the application runs perfectly, sometimes the error stop the application.

Someone knows what happens ?

thanks

Woully

Hi Woully,

If the computer running the shared variable engine goes down or crashes for some reason, any subscribers will receive error -1950679023  from the shared variable node error out terminal.

I have some questions:
Which version of LAbVIEW do you use?
Do these two applications run on the same machine?
Is this failure reproducable? Meant does the error occour at startup or after a  defined amount of time?
Have you tried DataSocket instead of shared variables?

In addition, you can find a good tutorial using shared variables following this link: http://zone.ni.com/devzone/cda/tut/p/id/4679

Hello Kilian,

i am using Labview 8.0.

Both application runs on the same pc.

The failure appears on the start of the software, but not systematically. It's very strange. I've read on a forum that the firewall can produce such an error. I've tested the software without any firewall or antivirus on the pc, but that have changed anything.

I used several shared variables, and curiously it's only one which occurs the error....

Hi Woully,

Thanks
