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

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
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)
For those who came in a bit later -- turn your sound on an check this YouTube video on the Rockwell Retro Encabulator http://www.youtube.com/watch?v=RXJKdh1KZ0w
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?
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
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

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
