I Can Only Hope You Intended to Visit Today


In this website I will bridge the gap between web pages, the people write for fun, and a BLOG. I contend that if you start a blog you have something that you would like to show the outside would and you want them to comment on it. If on the other hand you don't care what people might think about your rants you should start your own website. Wait... I do care. I just don't want to hear for others.



The Automation Evolution: The almost PC PLC Story


The current generation of computers would not exist without the knowledge gained by industrial communication revolution. The concept of a programmable logic controller (PLC) was the overriding idea to replace thousands of hard-wired relays, cam timers, sequencers and loop controllers that operated in manufacturing plants the world over. The invention of the integrated circuit (microchip) in 1958 was a great leap forward for both computers and PLC's and for all of us who use computers today. The impact of the microchip at first was not easily understood. Eventually the manufacturing of the microchip would reduce the cost electric functions by a factor of about a million to one.

The development of the microchip didn't happen overnight and it didn't fully integrate into manufacturing until the late 1960's. In 1962 the first computer game was made. Spacewar was invented by Steve Russell at MIT. Does that shatters the allusion that porn was the driver for the first computer game.

If you build it, they MAY... consider using it?

If you look at the United States manufacturing alone, it was the GM Hyramatic the "automatic transmission division" of General Motors that started the push for programmable logic. GM thought they could build computers to replace relays, timers, sequencers and closed-loop controllers. Believe it or not computers in the "Dark Ages" required large, clean, well air-conditioned rooms to operate properly. You have to love punch cards. Computers would not operate on the manufacturing floor and they would not fit into a small space. Computers in the 1960's could not be moved room to room and you needed ear plugs to work near the processors. GM thought it was cost prohibitive to build and move computers so they challenged outside companies to design something new.

My guess is that they were sick of having to manually move and rewire thousands of hard-wired relays, cam timers, sequencers, and other electrical connections every year when a new car model came down for manufacturing. In 1968 GM requested a proposal for a replacement to their hard-wired relay systems. The core plan was to build a task orientated mechanism that could work in the manufacturing work environment. The device would also need to be reliable and reprogrammable. The PLC would be an sequential control computer built to run functions blocks for all equipment and relays. GM intended to make the giant electric erector set computer fit into one small box.

Bedford Associates designed the 084 (project 84) and the Modicon (Modular Digital Controller) was born. The good old 084, was it Barbra Streisand? memories like the corners of my mind?

This is the Modicon 084 PLC

Although more than one person worked on the PLC project, Dick Morley is called the "father" of the modern PLC. I invite you to read about Mr. Morley he is without a doubt quite the character. Either way you look at it the PLC called 084 provided almost twenty years of continuous service before it was retired. How many home computer have you had in the last twenty years? Have you been using a computer for twenty years?

Now that's Logical? Does everyone remember where we parked ?...

Early logic was represented as a series of Boolean algebra equations. With Boolean calculations logic could be programmed and be automated in a relative sequence. Automatically turning functions on or off essentially making it possible for devices to operate. With the logic represented with a True or False, On or Off, 1or 0 the complete functions could be repeated over and over. Automation was now as simple as the light switch. It was a great leap forward with its simplicity because a light switch is either up or down, the door is Open or Closed the machine is Running or Stopped. The problem was you could not differ from the program or determine the state of a function. What if you walk into a room with two light switches and three doors? One light switch may be up and the other may be down, the door on the left is 30% closed or 70% open. If this happens will that difference interrupt and stop the sequence of programming? Yes the early PLC programming lacked simple State Logic programming and it was a problem.

This is the 084 Travel PLC

My early experiences with this type of logic was programming a CNC turret Punch Press, it included loading "punch paper " (punch paper: is a long roll of paper tape with a series of holes punch it) into an automated punch press. Everything worked great until you needed to change the placement of a cutout. To change the position or state of anything you would need to edit the program on the tape while the equipment performed the set task. We did not have a way to view the logic so we ran the program until we found the action we needed to change. At that point we would manually change the punched paper and restart, all because you could not see the logic to make changes left to right punch.

"Ladder Lister" is a statement based PLC programming language. The introduction of Ladder logic allowed for " If?.. Then" statement programming. In 1979 Modicon introduced Modbus ,RTU (remote terminal units) and ASCII. Modbus later became the standard. Modbus was designed to allow communication between 240 devices on the same network and was a major step forward. In the mid 1980s PLC proprietary programming panels were introduced and interactive terminals evolved to control dedicated functions. For manufacturers the PLC more than met their needs and to top it off ladder logic empowered more than basic control. With a screen and programming you could read the state and control all attached equipment on the PLC from one location, with the fast reliable Modbus system speed and fixed controller you could perform all actions in real time and bypass failed devices.

Today we use touch screens attached to PLC controllers to provide full control and automate all of the equipment on a multiple manufacturing floors simultaneously.

PLC's are still evolving to meet the need of the environments they are in. PLC's are used in industrial manufacturing systems, residential logic systems, marine or shipboard monitoring control systems and much more. Communications have leapt forward as well with PLC's utilizing Modbs with TCP/IP and UDP supporting 32 bit Integer and Floating Point variables. PLC's are used to control lighting, HVAC systems, security systems, CCTV monitoring, motorized curtains and awnings, computer networking and logistics, electrical generators and even in remote access phone systems with event driven messaging. The next time you drive through an intersection you are driving past a PLC controlled system. PLC controllers still utilize serial port communications.

Do PLC's have any future controlling tomorrow's devices?

The short answer is. Yes? Apple may already have an app for that. What will the future hold?

  • 1. Most computers manufactured today do not or use or design in serial communication ports to their laptops. If you get a new laptop you need a USB to Serial connector. I would design a Bluetooth or wireless connection module for this problem. If PLC manufacturers do not wish to go that far an Ethernet CAT5e connection, USB 2.0, or Thunderbolt (good luck with that one) would do.

  • 2. When connected to a controller most programs operate at 32 bit. Most new computers come with 64 bit OS standard and most PLC communication is still 16 bit or floating 32 bit integers. PLC logic needs to catch up to the modern computer systems design s and fully adapt to the double register system. For the most part in-house programming and designer may be forced to handle the changes themselves.

  • 3. Most manufacturers need to catch up to the times. New PLC systems are designed every year but used PLC systems are quickly repurposed. The truth is manufacturers are often not interested in investing in new technology. "My Windows Me machine does everything I need."
  • These companies will need to be pushed, pulled and prodded into the future. Cost savings from old systems infrastructure will make it difficult to push for the future.

  • 4. Memory, processors and speed. PLC processing is generally handled over a closed network. To stay ahead of the game they should be designed or include a bigger brain and more memory. The amount of packets handled should be increased and broadcast failure should be prevented.

How to Build a Time Machine


What people really need today is extra time and maybe their morning coffee to wash it down. I don't know about you, but it seems like I never have enough time to just relax. Not that I would be able to relax or slow my life down if I had the opportunity. In Dog terms it just seems like I'm chasing my own tail.

I'm not really sure why Doc Brown actually built the time machine and in the end I don't know if he truly accomplished his goals. What is important is it was a fun ride. Once you use the Flux Capacitor can you really go back? Google I'm sure has a team working on this exact concept.

It may take Google a few months to come out with a good Bata time travel app. By then this article will be out of date or is out of date when you think three dimensionally. Any reference to the success of the test will be inserted here. If you are reading this article and you do not see an update to the story, it may indicate that I have not had enough time to write something new. I seem to have misplaced my stapler. Have you seen my stapler?


Welcome to the Search For Aliens


The people in this image are pointing at an object that does not really exist. I wanted something a little different from the usual smile at the camera. The difficulty is that people do not like to do anything outside of their comfort zone. Sometimes people actually have fun when they are pushed into a new situation even if change is embarrassing. This picture demonstrates that this small group of people has not lost the ability to change.

I told them I didn't want them to just smile at the camera, I wanted them to point at the giant spaceship hovering over the parking lot, and eventually I was able to get these people to point at the imaginary spaceship.

I find it interesting that when you first suggest to people over the age of ten that you want them to point at an object in the sky that does not exist, they will look at you as if your brain has been scrambled and it exploded. If you try this with people younger than ten they will happily oblige the any crazy notion without question. They may even make up a song for you and sing it for Youtube. From the age of ten why do we lose that wonder, the sheer joy of having fun without substance abuse?

Depicted here is the culmination of a fifteen minute attempt to force people out of their shells, and you can tell in the end they had fun. They will even remember this picture, and moment.

Monkey

From time to time I will fill this page up with mindless but clever interviews with people respected for the work they perform. I don't intend for this to be a bathroom reader and you will not need to fold out the "articles" or require the pixel space to read my likes and dislikes or my favorite dissert and I know you don't want my measurements.

SEO Friendly

The higher up content is in your page code, the more important it is considered by search engine algorithms. To make your website as optimised as possible your main page content must come before the side columns.

It doesn't matter which column has the longest content. I will only distract you with good content.

I'm Bullish

For the most part I am very optimistic. I would like this to be an optimistic site that gives detail to unresolved issues of the day and future. I am not 60 minutes and I will not have a hard hitting report on school issues. I will not tell you who to vote for or what religion to practice.

Focus on the future Ideas

I would like to put future ideas for the site here. I'm not talking White Papers. I'm not looking at being an authoritative guide builder, and I'm more than happy to help people learn how to perform functions they may not know about. If I happen to provide a better understanding of the function of a product I will write a good article not a technical Guide for sales.
What I see written here is articles that are in the starting gate for future plans. For example I'm working on generating a cloud service for a client. I may write an article on the subject. How does it work?

CSS is good for the smart phone generation

I will use my writing skills to expound on my understanding of the future of the computer marketing and sale of web based karma. Because of marketing and selling a product often requires having a fixed base I will attempt to fill my web pages with relevant information to the life and times of the day. I will attempt to use fact based samples for everything that I do.

Service With a Smile

I want to provide a service with my web site. I have found that not all of the people writing code and working for the future have malicious intent. I am happy to help others in my life when I am asked. No, I do not limit the help I provide to computer or networking services. In my life I have discovered that life is relational in contextual terms. If you believe you can't do something you will be unable to do it. If you use the skills you know you have and learn new skills then even with a few trial and errors you should be able to learn, repair, or build anything you want.
