Re: [PSES] Safety Testing Sotware

[Doug Powell]

Brian,

Although I prefer a structured approach to programming, I had a good
experience with Labview, even though it is an icon driven programming
environment.  I think of it as more of a flow chart than a state machine.
In many ways it is similar to ETS-LIndgren Tile!

Your comment about ARM is intriguing and Python seems to be the language
du-jur. I wonder how agencies are to accepting data from single board
computers, I know it shouldn't matter and the idea of dedicated hardware
watching over a long environmental tests is compelling.  I personally don't
prefer Arduino, it is a good learning environment and has lots of expansion
possibilities but I feel it is somewhat limited on networking abilities.
In general, Raspberry PI certainly has more processing power, the linux OS
is pretty lean and it has good networking, but is probably not a good
choice for real-time processes since it is so interrupt driven.  I believe
Beaglebone may have some potential but have not really evaluated this
option yet.

All the best and have a wonderful Christmas,

Doug

Re: [PSES] Safety Testing Sotware

[Brian O'Connell]

We have had similar discussions on the automation of Type Tests. Might be worth 
one's time to search the archives.

Canned code that comes with the instrument can be effective. Have use 
Benchlink, and with regret, have noted that Keysight people have ruined a once 
very reliable (for windoze) utility (some of Benchlink's problems have been 
fixed by the Win10 USB implementation). Have droned at length on LabView, so 
will, at least once, spare our group from further my rants of 25 years of using 
this unsupportable nightmare (will somebody explain to these Austin PhDs how a 
state machine is supposed to work). Excel VBA can be surprisingly effective, 
but instrument drivers and other hardware-dependent code are frequently broken 
from each progression of versioning for either windoze or MS Office.

Test automation is more than data logging. Test automation adds smarts by 
watching the data stream and removing the human from any control of test 
conditions. Test Automation requires the use of deterministic response to 
hardware events. Test Automation requires the reliable and continued recording 
of data when things go wrong. Test automation systems know when something is 
wrong with the test instruments.

Typically have done Type Test automation using Python/C++ on a Linux platform. 
But as of late, have been using multiple ARM processors (at least M4) that 
control the tests, talk to the instruments, and stream buffered data to the 
computer.

My next big project will be to put Type Test systems into the factory for my 
employer's large magnetic stuff.

All,

Am aware of several EMC testing software packages available.  Today, I am 
curious to know if you use automated software for safety type testing 
(engineering tests).  I am also aware of solutions intended for high volume 
production line testing.  From my experience it seems that the most valuable 
software tools for safety type testing are available with the instrument, Excel 
VBA scripting, Labview or an in-house compiled solution.  I have used Benchlink 
from HP/Agilent/Keysight and if a custom application is needed with several 
instruments then I've used Excel or Labview.

What has been your experience?

Thanks!

[PSES] Safety Testing Sotware

[Doug Powell]

All,

Am aware of several EMC testing software packages available.  Today, I am
curious to know if you use automated software for safety type testing
(engineering tests).  I am also aware of solutions intended for high volume
production line testing.  From my experience it seems that the most
valuable software tools for safety type testing are available with the
instrument, Excel VBA scripting, Labview or an in-house compiled solution.
I have used Benchlink from HP/Agilent/Keysight and if a custom application
is needed with several instruments then I've used Excel or Labview.

What has been your experience?

Thanks!
