Thanks, very useful information.

Iron

Thanks Max, lots of useful information.

Iron

Hi from Oregon to archive knowledge

Good lecture would have liked to hear it live.

Iron

Looking forward to seeing how VHDL code generation progresses ... thanks for mentioning it

Good overview and selection of slides.  Looking forward to the last class Clive.  I have a lot of DN and EE Times articles to review it seems ...

Hey? Did I see the oft mentioned and never yet shown "Ladder Diagram" (LD?)?

Okay ready to review another one

Thanks, I'm looking forward to the last session.

Iron

Good refresher Max.

 

Iron

another good presentation Max.

Iron

interesting material

Iron

answering your self could be considered a sign of insanity... :-)

Iron

Great info! Thanks Max!

Iron

Answering my own question:

Plankalkül by Konrad Zuse

 

Iron

Anybody have a link to the first programming language mentioned in this lesson?

Iron

Okay Part 4 Catchup and I'm Done Catching Up

Thanks Max, another good session

Iron

thanks jrjohns, i came back for a second look and got the link to the Chrysler version. it's great!

Iron

Looking forward for your next lecture.

Iron

@JrJohns, JL, Thanks for the tip guys!

Iron

Thanks Max and Joyce2.

 

Iron

thanks Max, great presentation

Iron

Thanks all for your interest and attending, and thanks for another great session, Max!

Iron

@Max - See ya tomorrow.  Thanks again.

Iron

Thanks Max and Joyce, see all tomorrow.

Iron

@JoeFromOzarks: Only $750,000,000 per the original version, so plan on that plus an adjustment for inflation.

Iron

Thanks to everyone for attending -- see you for the final session tomorrow

Blogger

@THasham - You bet, bro.

Iron

Thanks for the presentation, Max. Got to go now.

Hi Max,

Thanks for your presentation about LD. Having gotten started with Eiffel OOP a long time ago now and progressing to using LabView after attending both CORE 1 and CORE 2 training over a one week period in 2010. The Modicon Quantum PLC seems to be very easy to program using the provided ProWorx 32 software with the demo limited version.

"Rockwell Retro Encabulator "   I still can't see --- I laughed so hard I cried!!! (Still, I want one!!)   :)

the SparkFun website is good also

Blogger

@jl, arduino is a great way to get started, lots of tutorials on uC, electronics, construction projects. Ther're affordable too. wish this was available many years ago when I started.

Iron

Someone asked why folks are still using Ladder Diagrams - -again, it's bcause a lot of the folks in the factory floor don't have university degrees -- they are trained on th ejob by existing folks, who were themselves trained in the same way - -plus they don;t know programming or anything - -LDs are a visual map onto what's going on in the real world

Blogger

@Max - Thanks for the work.

Iron

@Joyce2 - Thanks for coming.

Iron

@Ran..can you post the yt link here? Thanks.

Iron

@ran "I'm sending this out to all my buds."

You've got buds? :-)

Blogger

@gpapich - Take a look at Parallax, Inc's web site.  They have some starter kits with instruction books for sale at reasonable cost

Iron

@gpapich - get Arduino and be sure to get the "Arduino Quick Starter Guide". you will be building electronic gadgets in a days time.

Iron

@Max - I knew you had a sense of humor, but after watching your suggested video on youtube, I can hardly catch my breath from laughing so hard.  That was absolution unreal.  Thanks for the reference.  That was just great.  I'm sending this out to all my buds.

Iron

Excellent, Max.  Thanks.  I think the run-through of LDs (and inclusion of example diagrams) was quite useful for providing the historical context from which modern-day methods for specifying and programming industrial control systems evolved.  See you tomorrow!

Anyone know of any basic electronic kits, breadboards, banana leads, etc. that can help a newb guy learn electronics and logics?  I'm a gearhead, mechanical-engineering biased History major with a minor in general engineering.  I need a sandbox to play in to learn this stuff.  Looking at going into design engineering as a business later on.  Need the dim-bulb to at least glimmer...Thanks!

Iron

@luizxosta "how are the PLC folks handling multi-threading/multi-core implementations."

23

Just joking -- I haven;t got a clue -- but we will be talking about thsi a bit tomorrow when we come to talk about things like "determinism" and "response time" and stuff

Blogger

Thank you Max. Geart session.

Iron

The earlier representations of RLL used Text components to display the Logic

Never had audio problem until today..blame on Solar storms..

Iron

GREAT BASICS ON SWITCHES AND LOGIC. THIS MAKES UNDERSTANDING THE PROGRAMMING EASIER TO UNDERSTAND,

thanks Max

We at Rockwell have had multipule processors in our controllers for some time now.

@We're gonna miss you around here, Max.

I'm only an email away (max@CliveMaxfield.com) -- also I blog on www.Microcontroller.com and act as the editoir for the EE Times Programmable Ligic Designline and Microcontroller Designline websites (go to www.eetimes.com and click on the Design Tab and then select the designline of choice)

Blogger

Max: how are the PLC folks handling multi-threading/multi-core implementations.

Iron

@"I don't think there a single best programming language..it all depends on the use."

 

I agree

Blogger

You're welcome, all, and great job Max!

Iron

We're gonna miss you around here, Max.

Iron

@jrjohns, i tripped over scilab and octave while looking for an arduino project.

Iron

Max, Thanks for the lecture & list

Iron

Thanks for a great session Max!

For those who came in a bit later -- turn your sound on an check this YouTube video on the Rockwell Retro Encabulator

Blogger

Thanks for another great session, Max!

Iron

@Joyce2 - Thanks for coming.

Iron

Thank you Max, and Joyce.

Iron

Thanks Max and Joyce...

Iron

Thanks Joyce, I did have a lot of problems with audio going in and out.  Did alot of Refreshes

Slide 18: Great for basics.  Stuff I forgot/never learned while at the Naval Academy.  Thanks!

Iron

Hi Joyce. Sorry I called you Alex. :o(

Iron

problems are in College Teaching PLC  so you are right M>N

@Max - Thanks for the work.

Iron

List of "notable" programming languages
http://en.wikipedia.org/wiki/List_of_programming_languages

Blogger

Scilab and Octave are both options, each of which has plusses and minuses

Iron

for example, why did the IEC 6-1131-3 have to define a new language, why did they just not standardize on C/C+

Iron

Thanks..danlafleur for the info!

Iron

Thanks Max, great presentation. 

not sure debating the 'best' programming language is as productive as standardizing on a common robust language

Iron

MathWorks works with Rockwell controllers e.g. Control Logix.

for anyone interested in matlab, have a look for scilab. this is open source and seems to compare quite well... and free.

scilab.org

Iron

If you ask N people what the best programming language is, you will get M different answers where M > N :-)

Iron

I think C and C+ are used for more general applications.

Iron

I don't think there a single best programming language..it all depends on the use.

Iron

thanks @dnlafleur - makes sense

Iron

 ISaGRAF is a Rockwell Automation Company.

Debate on the best programming language option, Which one is the best?

@jr, i guess that ladder diagrams, looking like a schematic, were meaningful when the logic was still hardwired. NOw it's just a logic sequence.

Iron

ladder diagrams don't seem to be very intuitive. less than function diagrams. are LD commonly used in the industry. is there a trend to get away from LD and toward FD?

Iron

@caa028: Refer to this link http://www.plctutor.com/index.php?page=relay-ladder-logic

Hope this helps.

Thank you for showing Rockwell's Logix 5000 editor environment.

A common start point and a common end point... ?

Iron

So, the "power rails" on LD do not represent actual power rails... but rather just parallel circuits?

Iron

If PLCs handle multithreading/multi-core, the scanning scheme is probably not held, is it?

Iron

IEC 6-1131-3 programming languages. PLCs are often programmed in ladder logic.

Do current ladder programming include multi-threading and multi-core?

Iron

C with Ladder diagram in the same "source code"?

Iron

What is the differenct between PLC and PAC? More complicated programming options?

Iron

I agree that a complete education includes where the technology came from.

Iron

A hardware failure occurred. I'm back.

Iron

I am, not sure which one Max is on

Iron

Are we still on Slide 3?

Iron

how about a BIG shout out to @miket

Iron

@jl not always back:-(

Iron

@bobybacs: Yours just came up when I posted that.

Iron

Hi folks - if F5 doesn't refresh your audio, you might consider trying an alternate browsser.

Iron

You may need to refresh more than once.

 

Iron

after second refresh audio is back ;)

Iron

Guys just refresh it.

Iron

the (F5) refresh got the audio back

Iron

Yeah, happened to me twice already.  First time that I have had a problem with the audio, though.

Iron

I've already tried that

Iron

Just the mention of the ISIL language causes disaster.

Iron

yep, audio lost for a while, must be another solar storm ;)

Iron

I would consider C/C+ more a low level language, closer to assembler. especially with its cryptic syntax.

Iron

refresh and he comes back

audio dropped for a second

 

Iron

Did we just lose Max?

Iron

Anyone heard if the ISIL language?

Iron

Hi Max! Sorry for a few minutes late.

Iron

Greetings everyone, thanks for joining us today. If you are having audio issues, please refresh your browser (F5).

Iron

yes, refresh worked for me too

Iron

March Madness is amoung us. What is your championship pick

Iron

sound is ok.  referesh - F5

Iron

hello joyce, hello max.

Iron

Oh, and Hello everyone!

Iron

hope Alex is doing OK

Iron

me too, refresh your browser

If anyone else is having that problem, I just refreshed and it started coming through fine.

Iron

hello joyce, hello all

Iron

Good you're back again Max.

Iron

I had the sound stuck in a loop for a few seconds there.

Iron

Oops.  I see Joyce is here today instead of Alex.  Sorry 'bout that.  Hi Joyce.

Iron

Good afternoon all.  It is a beautiful day in the Nation's Capitol

Hello Alex.  Hello everyone.

Iron

will have to go look for the Chrysler video later.

Iron

@max Liked the Dingle arm on the encabulator.

Iron

@cnorton "I'm ready to go."

You are? I'm like a fine racehorse pawing the ground before the start of a race (grin)

I minute to showtime...

Blogger

The Chrysler video of the same name is also great, particularly the use of props during the transmission repair. :-)

Iron

Hi Max and Alex, I'm ready to go.

Iron

Good afternoon, folks.

Iron

Thanks Max, great video. Blind with brilliance or baffle with B..lS..t

Iron

with regard to yesterday's talk on Human-Machine Interfaces (HMIs) -- take a look at the following blog I wrote -- look at the third one from the end – the automatic teller machine

http://www.eetimes.com/electronics-blogs/maxs-cool-beans-blog/4236502/-Worst--Building-contractor-of-the-year-awards

Blogger

Good time for industrial programming "philosophy" discussion.

That's a great video :-)

Iron

Did you ever see the YouTube video on the Rockwell Retro Encabulator?
It's brilliant -- make sure yuou have sound turned on
http://www.youtube.com/watch?v=RXJKdh1KZ0w
Tell me what you think

Blogger

Good morning Joyce, Max and all.

Max, I noticed some new slides today :-)

Iron

Welcome back Joyce..

Iron

Good day everyone. looking forward to another great lecture from Max.

Iron

Hello everyone.

Good aftrenon Joyce2.

Iron

Hello Everyone - The streaming audio player will appear on this web page when the show starts at 2pm eastern today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser.

Iron

good afternoon again!!
