Labview slows down / hangs

[khmlv]

Dear Sir,

We are developing an application in Labview 2012 in which data is read from MODBUS TCP/IP port. These data bits (about 100 bits) configured as boolean indicators are processed to generate events on value change. When multiple such events are generated, the response time of Labview's user interface slows down to a great extent or hangs sometimes.

Do you think this is because of multiple event execution?

If yes, is there any solution to this issue?

Our PC has 8GB RAM and core i5 processor with Windows 7 Ultimate 32 bit OS. Whether upgrading the OS to Windows 7 ultimate 64 bit can help resolve this problem?

Thanks,

Regards,

Did you miss out event structure unchecking the Lock Panel?

-Ideally the processing inside event strucutre should be such that it should be processed before any next event happens.

-The above could be my guessing, if you post the code/snippet it would explain the problem bit more clearly.

Dear Uday,

Thanks for your prompt reply.

You probably guessed it right ! 🙂 We feel this should solve our problem.

Just out of curiosity, do you think by upgrading Windows OS to 64 bit from 32 bit can help to improve Labview performance because of efficeint utilization of RAM (I guess)? 

Thanks again.

It only helps if you have LabVIEW 64bit. More info : http://digital.ni.com/public.nsf/allkb/71E9408E6DEAD76C8625760B006B6F98
