Issue in connecting sub VI programs through the main program

[ymanglik2009@gmail.com]

Can you please elaborate how to debug the code or checking of incorrect commands.

Hi ymanglik,

NI provides good beginners tutorials for LabVIEW. They also explain how to debug VIs using probes, highlighting and single stepping.

Go through the tutorials to learn the basics. Then debug your VIs...

Hello GerdW, thanks for your reply.

Actually I am totally new to labview programming so I am not able to understand how to check common codes/SCPI codes in the programming. Even I have go through the manual but still I didn't get any clue to solve this problem.

Can you please help me to understand how to do this???

Hi ymanglik,

SCPI commands of your device are explained in the Programmer's manual of your device. Read it...

- Then you have to check that every command you send to the device conforms to that manual!

- To learn debugging you should do some practicing. Read the LabVIEW manuals and try out basic tasks with all those example VIs coming with LabVIEW!

Hi,

I am using LabVIEW 2013, and a Keithley 2410 communicating through GPIB.

I made a simple program, sending a commando to the 2410 to source a given current, continuously.

Then at given time intervals, I want to read the current voltage for logging in a txt file. My Idea is to do this

simply by sending strings of commands to the Keithley 2410.but I have some trouble with this. On interfacing, it is giving one error:

Output Ërror code: 6 in GPIB write vi

I have attached the program. please check and tell how to remove the error.

urgentlly!!!

Send the commands in a loop in the small test program so you can see which one causes problem.

Actually I am new to labview so dont know how to create a test program.Can you please refer any example of test program like this?

[Yamaeda]

Just change your massive string in the simple program.vi (your test program) to an array of strings and loop through them. Either gather up the errors as an array so you can see which cause problems afterwards, or break on the first error.

Hi ymanglik,

you should have known by now that the Keithley is an external device which is control using VISA. You send some commands to the device and you can read it's answers.

All the commands are listed in the User Manual of the K2410. Read it…
