EPROM...EEPROM question

[Bart]

I have a controller that can control a servo motor amplifier. I can load
programs to it thru RS232 and run them but if I turn the controller off the
program disappears. The controller has a "Burn" command that will save the
program to an internal eprom chip and then if I turn off the controller and
then back on, the program is still there. My problem is I can't download
from the controller to my laptop so any programs I've loaded and run, and
edited and run some more, and edited till the program runs perfect....I
can't make a backup copy of it. I've opened the controller and there's no
battery inside, so could I remove the eprom from the controller and put it
in my eprom burner and download the file directly from the chip? And then if
I put the chip back in the controller the program will still be there to
run? Sorry I don't have the numbers off the chip 'cause I'm at home dwelling
on this problem.
Any advice is appreciated,
Bart

Hi John and thanks for your reply.
The controller has editing capabilities and the program that comes out
of the office is edited quite a bit in the controller till it performs
adequately
on the shop floor. The final "proven" program is sometimes quite different
than the original from the laptop. We've tried having the setup fellas
document
there edits but we end up with illegible notes on several scrap pieces of
paper.
The setup time is extensive and when a certain job is run again 3 months
later,
the setup guys take the original laptop program and "re-invent the wheel" so
to
speak. It would only take an hour to open the control and pull the chip and
place
it in the eprom burner in the lab and download it. It takes till noon for
the
setup guys to edit the original program out on the floor.

Ah, I get it.

Your "remove and read" scheme should work perfectly.

It might even be worthwhile reading the chip immediately after the
editing is done on the floor, no?

That way, you'll have the file no matter what happens to the
controller...

if the controller has editing facilities can't they be used to get a dump
of the contents of the memory?

Hi Jasen,
Unfortunately, no. The edit feature has no commands for a dump.

Hi Jasen,
Unfortunately, no. The edit feature has no commands for a dump.

so they have to edit the program without seeing what they're editing?

Bye.

I concur wholeheartedly with this, plus, maybe have some of the setup
guys brief somebody on what they've done - maybe a company edict or
company-provided shop logs or something...

Cheers!

It probably displays some codes on its own display, but doesn't have
a "send the codes back up the data line" command.

Cheers!
