Pick Instrument from IDN? result (case from string)

[kornyguy06]

I'm trying to figure out how to read from several differently formatted instruments' IDN? result (GPIB) in Labview and pick a case to control that specific instrument. I've tried several different string search/scans and nothing seems to work quite right. The method used in the attached vi is taken from the NI official intialize driver for a E5071 network analyzer. but since it only works for Agilent ENA series VNA's it doesnt account for another IDN? format. The other two analyzers we have are 8714ES and 8753.

Thanks,

Jamie

Fortunately, those identification strings are intended to be human readable -- but not computer parseable.

So why is it that you don't know ahead of time what Imstruments are installed?

I do, I'm creating a program for the production floor however and the fewer variables the less likely the cannibals out there can mess something up. Basically when I'm done all the inputs will just be 1 scan from a barcode and then it will do all the testing and print out a report/save the data to a sever.

Can you post a 2013 version?

I hear what you are saying, and your end goal is very good so don't let anyone dissuade you. However, concerning the "cannibals' that sounds more like an HR problem.

Well, maybe I was a bit too harsh on them... Maybe just monkey's. Does anybody have a solution?

Attached for version 8.5 (just in case) and 2013 as requested.

Does this work?

Yeah, the solution is real simple:

"You take parts out of a production system without prior approval and you're fired. Period."

"You make modifications to a production system without prior approval and you're fired. Period."

Real simple problem to solve.

I think that'll work! Thank you mcduff! I looked over all the threads I could find on here about this and couldnt figure this out, didn't think to read it as a comma deliminated array.

mike- the application will be built so I'm not worried about the code, they already have that fear of being fired about touching the instruments and computers. I was more worried about them not changing a control for the particular analyzer they are using and having to get a manager or me over to them complaining they can't do any work because the program won't run.
