How do I get channel names written into a logged ascii file in Signal Express

[Omniquito]

Hi there,

This maybe a rookie question but I am a relative rookie to this software, and I hope it has an easy fix!

Background:

Take a load of analogue inputs from a DAQ device into Signal Express, first thing that hits me is that unlike labVIEW you cannot right click in the channel configuration window and change the name from say... Dev2_ai0 to Air Pressure? I feel that if this was possible then I would overcome my problem? anyway I can't so onwards...

I goto the DAQmx Acquire window on the top left and can right click and rename the channel, which is great... however this does not translate to the logged data as I get the ai0 channel names across the top of the columns and not the names that I have put in.

Is there anyway of getting data like the attached snippet?

Many thanks for your help in advance.

Hi,

You mention you right-clicked on the channel to rename it, which is correct. When you then click Record to acquire the signal, in the Logging Signal Selection box that appears, can you expand the channel tree by clicking the plus sign, and confirm whether the changed channel name is reflected here (as it should be changed here as well). I have tried right clicking the channel name as you describe and then viewing the log file, and the changed channel name is reflected in the log correctly, so I am just trying to see if your copy of SignalExpress is working correctly.

Hi Dan,

Thanks for the reply, that has certainly fixed my issue as I wasn't expanding the channel and selecting the channel that I had renamed.

One last thing though:

I now not only get the individual channel name but the prefix for the DAQmx Aquire, for instance I get the Input of Braketest and then the channels under the input data.

It looks a bit like this....

Braketest - Front Pres

Braketest - Rear Pres

Braketest - FR Temp

Braketest - FL Temp

etc etc...

Now all of the channel names at the top of the columns have this long name. Can this be rectified? can I remove the "Braketest" bit?

By the way I am saving it as an ASCII so that I can read it in excel.

Many thanks, Neil.

Hi again,

I think that the Braketest part (i.e the task name) is always appended by default, I can't find a way of removing this at the present time. I will respond if I find out how to do it.
