Time Coded Analog SIgnal

[HYDAC_R_and_D_Lab]

Hello Alipio,

I wired the origional version to my DAQ device, it worked but the trigger would not reset some some readings were inaccurate.  Also, I have two devices with this signal on two seperate channels on my DAQ.  I will wire in this new code to the DAQ and give it a test run.

Thanks,

Brian

Hello Alipio,

I used the updated code, much better.  Thanks this is fantastic!  I scaled the anolg signal output signals to their respective values and the reluslt are good so far. I have a  question.  What is the best way to run two sets of these loops (the Producer Loop and Consumer Loop)?  I used the code for both devices and since they basically gave the same signal, differing only in amplituce for the 5 signals, the results were the same-it worked.  Thank you for your help with this project.

Thanks,

Brian

Hello.

Probably, you will need only a producer loop adquirig 2 channel simultaneously. Then, separate the channels to  fill 2 different queues.

In that way, you will need to duplicate the consumer loop to have the tu signals processed. To avoif  probelm wiht subvis, make a copy of every subvi and rename it or try to make then reentrant.

If have problems, Next week iI will try to make it for you.

Cheers

Hello Alipio,

I have not had time lately to try your suggestion for using two different "time coded" signals in one LabVIEW program; shift in projects.  I am now back to continue and finish this project so I should be able to attempt it later today or tomorrow.  Thanks again for your help.

Hello Alipio,

The code works for the two devices that have this signal, perfect.  Now I need to develope a program that can incorporate at least two such deivces with this signal pattern.  I tried to make a sub vi on the code you had written but no luck.  I made a simple program with a DAQ assistant to bring in data then connnect the data to my a signal in terminal on the sub vi.  How can I make the code work so I have a sub vi, or is it easiser to modify the current code to accept two such signals.  I am pushing for the sub vi because I have several 4-20mA analog signals in the program (temperature, pressure etc).

Thank you for your help!

Here is the sample code.

Hello.

No problem to use the code for various channels. You have to code the processing part as a subvi and make it reentrant.

I have no Labview on hand right now, so I will try to look yor code in 2 or 3 days.

Will post back when solved.

Cheers

Alipio,

Nice, thank you for your help.

Cheers and have a good weekend,

Hello.

I have no labview.

I will try to get one as soon as posible.

In the meanwhile, you can try to make a subvi of processing part and make it reentrant.

Cheers
