I am trying to achieve the 26kHz PID loop with a PCI-7041 RT card. But, just reading from the card (AI Config.vi+AI Start.vi+WHILE LOOP[AI S-Scan.vi] +AI Clear.vi) takes about 0.3 milliseconds per iteration(one reading). Setting the scan rate higher than 8000/s gives an overflow error message. AI Mult Pt.vi is fast, but I need to read the data point by point to be able to process it fast. I couldn't find a helpful example. Thank's !
