Sorensen XEL USB controls works but not great

[Sr Test Enigneer]

I am new with LabVIEW and I am trying to develope a program to control my power supply. I updated a small program I got on this site but it does not  do exactly what I want. Essentially, I would like to be able to select voltage and current and be able to turn on the output which, from the manual I need to use OP 0 to turn off the output and OP 1 to turn it on

Was wondering if anyone can help out?

Good Afternoon,

So I looks like you are trying to communicate with your power supply using VISA commands.  Since you are new to LabVIEW, I would first suggest opening up Measurement and Automation Explorer and opening a VISA Test Panel for the serial port connected to the power supply and trying to communicate that way.  This will allow you to verify that you are sending the correct commands, carriage return, etc. without having to run the LabVIEW code every time.

Also, have you been able to run code you attached with your power supply?  What kind of behavior have you seen?  I hope you have a great rest of the day!

Yes I did have MAX check if the code works and it does  OK. I also am able to run my labview code but it is just my program look awkward

When I run the code it does as expected, it gives me the ID of the unit and sets the power supply voltage and current

I wanted to be able to set the current from the frint panel insead of doing it in the code and was hoping someone can give me hints

I have created a VI that seems to work OK so far

Was wondering if anyone had suggestions on improving it or if they see errors in my code

Any help is appreciated

Senior,

Your code is looking good.

You may consider routing your errors outside of the while loop and using a single error handler.

Also, the sequence structures may not be necessary. You can use your error wires to verify code execution order.
