Warning: Connection to the MyRIO-1900 hast been lost

[moidrissou]

Hey,

I am running a VI, which compares two camera Images and overlay the differences between both. this works like expected. but sometimes i am losing the Connection with the MyRIO target automaticaly or it does not even run. I then get the warning: Connection to the MyRIO has been lost or Deployment with Errors. but i can't see any Errors in my VI.

Can someone please get a look on my attached vi and may be tell me which mistake i am doing?

I use Labview 2016 and a Basler camera.

Hello moidrissou,

please monitor the CPU usage, if it is higher then 80% it could happend that the RIO lost the connection sometimes, because always some peaks can happen and the usage rise up to 100% and then first TCP/IP transfer will be canceled.

Also think about an meachanism like network streams to transfer the picture from the RIO to the host, you are doing front panel communication, which also need more CPU usage.

hey Alex,

thank for your Support. Your first solution was helpfull. The free Memory was bellow 5MB. I Formate my System and now it works.

Now i am using MAX to set a ROI for my camera.

Thank you again for your help
