One of the machines I programmed 9 years ago. This wasn't one of the more
difficult programs I done but it was a small machine with a lot going on, we
got it running in the shop, where I could video it, before delivering it. I
keep this on my USB stick, with other stuff, in case I get an interview and
they want to see something I've done more than the simple examples they have
you do.

Now once again I'm underemployed but it pays good for this area this time!

Roger, this looks pretty awesome, I would say.

Back in that time frame I made a robot cell that edgefolded carpet around a formed package
tray containing a CHMSL (Center high mounted stop light). The operator plugged in the
light (two bulbs) and I checked to see if we drew two bulbs worth of current at the end of
the hotmelt application, edgefold cycle.

Some of the bulbs we used didn't make it.

Thanks Iggy,
It's not that difficult to get a machine to do many processes at the same
time, the biggest obstacle is to un-learn what you learned about programming
through the examples that taught you to hold up the process while waiting
for a condition to be met.

Sounds related, the machine in the video was to supply bulbs for a
manufacturer of automotive lighting assemblies. Not in the video is a
station we added later to install O-rings on the sockets, the leak test
instrument could detect a hair under the O-rings. I also wired and
programmed some of their workcells that performed different operations on
the lighting assemblies. Some induction heated studs to press into the
fixtures, some welded housings, etc. It was a neat setup, they had machines
that operated like a press but the die sets were easily changeable for the
tooling for different model years.

Very nice. How are you with A-B SLC500 plc's? If I ever get back
to re-programming my Brown and Sharpe surface grinder I may have some
questions. I started a year ago and then got busy and have not had a
chance to get back to it.

Thank You,
Randy

Do you have to place your final product in a tray like roger did. That looks
to be the tuffest part of this little machine. Keeping track of part place
position through machine stops, Estops, and restarts can be a stone bitch.

Say, aren't you looking for an underemployed PLC ladder logic type a guy?
maybe there's a marriage made in RCM about to happen.

I was thinking about something on that line. At work we have Siemens (among
others) controls and have Siemens form Germany to go online with our
equipment for programming. I'm not sure of all the networking details but
Tom could probably set up a PC that I, or anyone he wanted, could VPN into
and program his equipment. He would need someone that could wire switches
and coils but once that was done the program could be downloaded,
troubleshot, and improved all by VPN (We use UltraVNC, free and works
great).

Y'know, that works great for some things. But there are just points in
the design & debug process where I want to be close to the power switch,
so I can slap it off if things start melting.

No chit. When I bought a license to RSLinkx I realized I could do some real damage from
my office. Had to change some wiring and programming to deal with that possibility.

SLC500 is one of my favorites, I have a SIC 5/04 (and a couple of PLY 5's)
at home that I play with. I got the PLY 5's because the 1771 rack cards are
relatively cheap and plentiful but I connect it to the SLC500. That
Mitsubishi PLC has the entire program in one ladder file, AFAIK they don't
have separate ladder files like a PLC5 or SLC500.

On the machine in the video I used the help of a spreadsheet to organize the
program and it is very easy to find out what is going on very quickly. Each
station has a set of bits for each step, if the thing doesn't index, you
just look at the index rung and one of the stations won't be ready for
index, go to that station and see what step it's hung up at. At the time of
the video I had just got it running that day and it had about 2500
instructions. The final program had around 5600 instructions, many of the
additional instructions were to display errors on the screen, if the machine
stopped they needed to know why without plugging in a PC.

I added an "index permissive" bit for each station that allowed the table to
index as soon as each station was clear of the table, it didn't have to wait
for each station to be done and home before indexing. This saved time and
the customer said this machine out ran all their other machines and they
were setting it up to run more different types of sockets.

Yeah, for the major part of the programming and start up the Germans were on
site, it would be kind of dangerous messing with 5000HP worth of motors and
drives from a long distance, then again you don't want to be too close
either.

In my programming experience I've learned from mistakes and I made a lot of
them so I guess that means I learned allot!(?) :-) The programmer doesn't
necessarily have to be on location but there has to be someone there to
operate the machine, make sure it's safe, and stop it in an emergency.

It seems like the Germans that program our equipment have a goal to make
something as complicated as possible, they seem to think it's cool if no-one
understands their program. I'm the opposite, I like to make things so
simple that even I can understand them! For the machine in the video, the
electrician at the plant was able to understand the program and add
additional parts himself. Product options included 1 or 2 filaments and
clear or amber bulbs. The station after the bulb insertion has 2 banner
mini-beam photo eyes, a red one could see through clear and amber bulbs and
detected if the base wasn't fully seated, the other photo eye was blue and
detected amber bulbs.

If you use cygwin to implement a ssh server, putty to tunnel with, you can then use a *VNC
to get a secure connection to a remote windows desktop. This is an all Windows example.

Until they changed the admin pw at work, I had a neat way to get back to my pc at home
using their copy of RealVNC with a tunnel using Putty on my usb drive. Oh well, it was
sweet while it worked.
