How do I display a task in a graph?

[daveyK]

Hello all.

OK I'm using LabView 7.1 and I have a DAQCard-6024E in my laptop.  All I'm trying to do is log 5 voltage signals simultaneously.

I've created a task that should get my five signals.  I place this task in LabView and try to connect it to a waveform graph.  It doesn’t work because it says one side is a task and the other is a 1-D doube (the graph).

Does anyone know what I'm doing wrong or if there is a simple way of doing it?

Shouldn't I be able to do this without using a task and just use the Instrument I/O assistant and pick the DAQcard from there?  When I do that it just says COM1 and I can't pick PCMCIA which is where the card is. 

All I need is just these 5 signals graphed.

Thanks for your time,

Dave

A task is a reference to a DAQ function - it is not the data returned from an acquisition. If you have a DAQmx Read, then you would wire the 'data' output to your graph.

You don't use the Instrument I/O Assistant for DAQ. That is for serial/gpib/vxi/.etc instruments. For DAQ, you use the DAQ Assistant that is on the DAQmx palette. If you use this, you would simply wire the 'Data' output to the graph.

Thank you very much Dennis.

How do I get to the DAQmx palette?  Would it be in the "Input" button?  Because if so then I don't have it and that would explain it.

Thanks,
Dave

OK I have the DAQ assistant here on my desktop but not on the laptop.   I have two CD's here...NI-DAQmx and Traditional NI-DAQ(Legacy) which one would be the one to install on my laptop?

Thanks,
Dave

To get the DAQ Assistant and DAQmx, install DAQmx.
