Lost data trough VISA

Hi eveyone,

 

I'm implementing a .vi to adquire data from a device through VISA. My issue is that my device send the data from its eeprom every 1 second. I show the data received via VISA in a wave form char to see the value and I can see that the data update every second... It lasted much time to update it, so I think I'm losing data because it seems like Labview didn't have time to get it well!

 

It's is possible that the configuration VISA has a delay and made that I lose the syncronism of one second to read well the values?

 

It could be possible that was problem of waveform chart because not updated at time?

 

 

Please, help me with this issue! I dnt know how to do to solve it...

 

Thanks!

Hi mlop,

 

1) You only need to "configure VISA" once at start of your VI!

2) Show your VI for more detailed help/comments!

 

Are you talking about serial communication? VISA is a generic architecture allowing several different communication protocols aud busses...

Best regards,
