Besst way

What is the best way to do this i Labview:

- combine multiple diffrent signal(boolean type - 0,1) to data logging

- then from this "data log" do some "background" calculation(in labview)

I was looking something with "Collector", "write to measurmetn"... is this easiest way; any advice please?

thanks

Any idea, advice... on that?

Your description is way to vague to give any specific advice.

OK. let's say, I have some input data(real signal from one process) which I must save to some sort of "data base". This could be an .txt or excel file whatever. In background of running this process I must calculate some values for example average, and time production, after that I will also add some graph(for analyse)..which I like to calculate from this already saved "data base". Now I'm searching for tutorial or any advice how to do this at easiest way?

I hope that now is more clear what I want to do.

Hi hlod,

There are still a few things that could do with clearing up:

- Where is your input data coming from?  What hardware are you using?

- Have you considered analysing the data before it is logged?

Everything you have eluded to sounds like it could be achieved using Express VIs - these are configuration based so the coding is minimal.  There is a tutorial which builds up an example of analysis and logging of a simulated signal - although you could adapt this using the DAQ Assistant to use real measurements from one of our data acquisition cards/devices.

Depending on your level of experience it may also be beneficial for you to have a read through the Getting Started with LabVIEW literature.

Hi,

well none of your link not working for me;

Input signals are digital and comes from PLC (OPC server)

I need analysing from data which I get from whole process, also need to make some history, so i can choose for example how mayn pieces was created 3 days before, what was average of product, time to make one piece...

thank you.

Hi hlod,

All the links work for me - have you tried again today?

Using OPC servers to speak to a PLC is a different discussion - what have you achieved so far?  A quick search of NI.com, and the Example Finder in LabVIEW (Help > Find Examples...) should get you some resources to get started.
