I will be working on a project that would aquire 4 signals from 4 moudles in the compact DAQ with diffrent sampling rate for each signal. I am looking for a hint to structure my code to do that and at the same time for all signals

Hi, Is it possible for LabView to aquire multiple analog signals at the same time with diffrent rate. Thanks

QUOTE (Dan DeFriese @ Jan 27 2009, 04:19 PM) Thanks fo ryour reply. actually, this would be finr if i wouldlike to have additional sognals from the same moudule (device) with the same rate. but, in my case I wfant the signals to be aquired from diffrent NI moudules f sampling rate. For this, sampling rate control need to be avaliable for each signal like the one on the front pannel. Can we do that. Thanks

Actually attached file is the developed VI to read and log one analog signal. It reads the signal and log it to TDMS file. The front panel and block diagram are also attached. Simply, I would like to have help to modify the attached VI to read 5 analog signalsle instead of one separately and with different rate, number of samples and max and minimum as it appears in the front panel controller configration. (To have similar front panel configration merged in one fron pannel for all) and working similtaniously at the same time to quire 5 analog signals Can any body help me to change the attachment to read 5 signals instead of one at the same time. I have tried my best to modify it but with no luck.

Hi, I have seen your great forum website while browsing the internet. First of all |I would like to introduce myself. My name is Walid . I am working in Research & Development Center. Currently I have been assigned a project to develop Data Acquisition System for I.C. Engine using Labview In our application, we need to acquire 5 analog signals from the research engine ( intake & exhaust pressures & temperatures and cylinder pressure). These signals to be synchronized at the same time with each other and triggered by speed encoder so that every 0.1 degree for example we will have a set of readings for all signals including the engine speed. Speeds here are fixed 600 and 900 rpm respectively for each test. Both the software and data question hardware were purchased from NI and Kistler as following: Software: · LabView Hardware: · NI Compact DAQ chaises with modular instrumentation 9205, 9211, 9215 and 9401 · Pressure transducers (Kistler) · Signal conditioning platform (Kistler) · Speed encoder with 3-TLL signal (kistler) data sheet and connection attached. I would be thankful if you could share with us some support in this project to develop the code and the software structure. · Looking to hear from you soon Best Regards, Walid
