Hi
I am using LabView IVI Driver to program/control AC power source.
My programm is working fine. I am able to control voltage and frequency of device and can measure the output parameters (voltage, current, power etc.) but there is latency problem in execution of control commands and measurement of data. Using the same interface rs232/settings, I can control device and measure data at very high speed (in ms) using device properiety control software.
I tried using fast execution time (1ms) for while loop but each of sub.vi using ‘DLL Call Library function’ take about 0.2sec to execute. (shown in attached snap). Totoal execution/data measurement time of main VI (ciLxs_LV_sample.vi) is about 1sec but I need to run it as fast as 1ms. I have also tried different technique given in knowledge base “VI Execution Speed” but execution time remain same.
Could you please advise how can I increase the execution time/speed of main VI and sub-vi’s (that are using DLL call liberary function)?
Thanks you and regards,
