Hello guys. i want real time acquiring data from multichannel tempretaure datalogger ( 45 channel ) each channel acquires tempretaure, and plot it in a waveform graph or chart ( still dnt know what to use ) . this temperature device is the hikoi datalogger. But i m facing an issue : the user of the device must set the acquisition period before turning on the measurement . the acquistion period can be 30s ,1min,2min,5min,10min,20min,30min,1h. How could i acquire all the data from each acquistion period and avoid data lost and garanty the synchronisation . I'm trying to use a cnsumer producer design pattern but i m still dnt use it well . Could you help me please .
While I have never used that exact instrument I have used similar instruments from Agilent and Keysite...
Instead of using the instruments internal timer to take measurements at regular intervals and store them.
You LabVIEW program needs configure the instrument, run the timer, take the measurements, and transfer measurements from the instrument at regular intervals.
I can't see you VI (I'm on LV 2020) but I imagine you can set up your producer loop to look for data available (as provided by the driver you are using). Grab the data and send it to the consumer loop to save or process.
PS. there is no such thing as real time in programming, there is only real fast : )

thank you ..so should i fix the loop time as like as the interval of acqusition? ( every user can put his own interval as i said above ) ie the execution time of the producer loop must take as an input ( control ) the value of the inerval ?
