Hi!
We have just purchased a Compact DAQ with NI 9203, NI 9217 and a digital card 9421. In the application for which these parts have been purchased I want to measure flow, power, pressure, temperature and water and energy consumption of a sterilizer. I have connected the flowmeters, and pressuremeters to the analog current card 9203, the RTD termomters to the 9217 and three digital pulse outputs from two flowmeters and a poweranalyser to the 9421 card. I have configured the analog inputs on 9203 and 9217 to my satidafction. But now to my question. I want to configure VI to count the digital edges from the three channels in the 9421. I know that the card only has two counters but since my pulses only has a frequency of approximately 1 Hz I believe that i in some way should be possible to count the edges with a regular digital input channel as well.
I know I have signal from all three pulse outputs to the 9421 card, since I have tested this in the Measuremnet & Automation explorer.
Do I need to add an extra DAQ-assistant to be able to acquire the digital signal parallell to the analog signals from the two other cards?
And is it possible to count the edges of mylow frequency on say for example channel di0, di1 and di2 as i wish and not only on di0 and di5 which I think are the counter-channels?
Do i need to put the 9421 card in one particular slot on my cDAQ-station, this I also ask since my pulses frequnency is low and I don´t now if i really need to use the counter on slot 5-6 to count my pulses?
