Porperty "Descritpion" of a global channel

[Heinrich-Hans]

Hello all,

I have have to update a piece of software (written in LabVIEW 6.1) which read the description of a DAQ-Channels and dsiplays this information.
It uses the traditional DAQ functions (the channel descriptions can be set through the M&A Explorer).

After switching to LabVIEW 7.1 for the software and DAQmx for the hardware, I found, that the description of a channel could not be set through M&A.

With the property "Description" of a global channel used in LabVIEW, I can assign a description to a global channel. But this description is only available as long as the software is alive.

Two questions:
1. Where can I assign a description to a global channel
permanently (like to traditional DAQ channels)?
2. Is this the right place for my question?

Regards
Heinrich

Hi!

Sorry, but a description for a global channel isn't possible with DAQmx.

It's impossible, anyway, to change parameters or the description and save it back to MAX!

I will write a product suggestions for it!

Your question has one part of LV and onother of DAQ, therefore, i think, it doesn't matter whether you post it here or within the DAQ forum.

regards,

Hi - you can programatically update and write to a global channel in DAQmx 7.4 and higher, however you cannot do this through MAX directly, so you have to make your own utility to do this.

Have a look at http://www.ni.com/info

and type in daqmxpro in the box.

Hopefully that will give you enough information for the future.
