=============================
Allen-Bradley is the brand name of several product lines of factory automation equipment and today its owned by Rockwell Automation.
The company was founded by Lynde Bradley in 1903 with the financial support backing of investor Dr. Stanton Allen, the company eventually became the Allen-Bradley Company.
Today, the company manufactures programmable logic controllers (PLCs), human-machine interfaces, sensors, safety components and systems, software, drives and drive systems, contactors, and motor control centers.
Their first patented product was a carbon disc compression-type motor controller used for industrial cranes and the crane controller was exhibited at the St. Louis World’s Fair in 1904.
Allen-Bradley became involved with programmable logic controllers by the inventor, Odo Josef Struger. He is often referred to as the father of the programmable logic controller.
Allen-Bradley became a major PLC manufacturer in the United States during his employment with AB. He also contributed as a leader in the development of IEC 61131-3 PLC programming language standards.
The first Allen-Bradley PLC introduced to the market was the PLC-5 product family. The PLC-2 and PLC-3 were released in the 1980s and are now obsolete.
The PLC-5 family used the 6200 series programing software originally and then later RSLogix 5 programming software.
In 1991 the SLC500 product line was released.
This platform was much smaller in size and had a reduced instruction set.
SLC was an acronym for Small Logic Controller and the first SLC500 released was an integrated package (commonly referred to as a shoe block PLC) containing the CPU, power supply, and IO.
The Micrologix family and SLC 500 PLCs used the RSLogix 500 programming software.
In 2014, the MicroLogix family was introduced in response to address the need for a less expensive PLC solution to compete with other manufactures and the first MicroLogix introduced was MicroLogix 1000 supporting several types of IO combinations. The platform did not use a rack but instead, modules were connected at the end of the package.
The ControlLogix family was introduced in 1997. This platform was racked-based having much faster scan times (speed) and memory than the PLC-5 or SLC products. Communication modules supported Ethernet, DeviceNet, DH485, and ControlNet.
Servo motor control cards using SERCOS fiber-optics provided competitiveness in the coordinated system servo market.
The CompactLogix family was released in 2008 as a lower-cost solution to ControlLogix for competitive reasons. And like the MicroLogix, the products do not use a rack-based solution but instead, use add-on modules to the ends of the power supply or CPU modules.
Communications between the RSLogix programming and configuration software and PLC/PAC is handled using Rslinx software, a separate software package, that also supports DDE and OPC support.

First of all - great video!
Some things worth of note I think for future reference:
1. I know that is most likely overlooked but this timeline should not confuse the representation of PLC2/PLC3 with SLC5/02 5/03 numbers.
2. Micro800 Family exists as the currently Active PLC family with Free Support (8-5 CST) and Free Programming Software being CCW (Connected Components Workbench)
3. ControlLogix has many more capabilities, also achievable through encompass partners of Rockwell but more importantly - when it comes to motion it supported Analog motion and Hydraulics modules before Sercos and now supports Ethernet/IP (CIP) motion. (Not Mentioned also that it does need RSLogix 5000/Studio 5000 Logix Designer to operate)
4. MicroLogix (other than ML1400) is obsolete now, although does have free version called RSLogix 500 Micro Starter Lite which is up to v8 and does have MicroLogix Emulate
5. New Introduced CompactLogix series 5480 is also IoT and changes the way that you normally look at PLC so it is worth a note. IoT is independent from Logix Engine so it has 3rd party support for other solutions like visualization.
Overall - great job - just wanted to clarify some things.
I'd be happy to help or elaborate if you want on some stuff. I appreciate all content you are creating and keep up the great work!
John, thank you for your observations and comments! PLC's have evolved over time, and some of that history you have eloquently highlighted. As with the evolution of controllers for motion control, it will be exciting to see how (and if) products like ControlLogix 5480 with embedded IoT features will change the way control systems are designed. As hardware becomes more powerful and feature-rich, Control and Automation Engineers will have more choices of a platform for solving problems and adding value. Thanks again for your comment and your support!
I am doing an engineer co-op program concentrated in process automation. Your videos help me a lot!!!! Thank you!!!!
That's great to hear, Ken! Best of luck with your program. If you have any questions along the way, feel free to reach out.
Thank you RealPars
Just a quick note on your very good outline here, Odo Struger's most prominent work around the early development of the original AB PLC dates to the period 1968 - 70 and specifically his most enduring legacy was the idea to animate the old electromechanical drawing standard into what we now call ladder logic. It was the first GUI in computing history as far as I know, and it remains the dominant language 6 decades later.
I had the enormous privilege of spending a day with him in Wellington NZ, (I worked for RA at the time) one on one, just a few weeks before his passing in late 1998. He was very clear the work Dick Morely was doing during the same period at Bedford Associates around the early RTOS and hardware implementations was very important to the whole development process. It must have been an exciting time to be a young engineer -
Thanks for sharing that, Philip! Truly appreciate such insightful comments!
'I've recently installed the rs logic 500 and RS linx both with emulation all free, this lesson was just on time to get familiarized with AB, thank you Realpars
Great timing! Thanks for sharing, Yasser - happy to hear that.
Outstanding, very informative, easy to follow!
Glad it was helpful!
x2 on the 'easy to follow' part. Look, I'm not even a native English speaker but I find it so amusing that it could even be understood by people who have less of a clue than I have
Thank you for this resume, very helpful !
You're very welcome!
Well, they got some product stuff wrong. The original Allen-Bradley PLC was simply called the Programmable Logic Controller. Some people now refer to it as the PLC-1, but that was never it's official name. It was introduced in the early 1970's. In the mid to late 1970's they introduced the PLC-2. This was an entirely new PLC system and little of the original PLC was compatible with this new system. They obsoleted the original PLC and upset many of their customers when they did not have a path to upgrade to the new system. A-B learned an extremely valuable lesson here and most of their future products provided a means to upgrade. The PLC-3 came out in the late 1970's or very early 1980's. It was not a replacement, it was an enhancement. It allowed one controller to control much larger processes than the PLC-2. The PLC-5 came out in 1985 which was the same year Rockwell purchased Allen-Bradley. It was intended as a replacement for the PLC-2. The PLC-5 was a huge success and essentially cemented A-B as one of the two biggest players in the PLC market. They later came out with a PLC-5/250 (Also known as the Pyramid Integrator) which was intended as a replacement for the PLC-3. The PLC-5 family used the same I/O as the older PLCs so users could very easily upgrade without having to rip out everything. The PLC-5 controllers were available for nearly 30 years.
There was also a PLC-4 which never really took off. It was intended as a small inexpensive PLC but A-B never put this into a catalog. As far as I can recall, the US Navy was one of the few customers that ever used this. A-B decided to pull this product and entered a partnership to brand label a small PLC from the Japanese company Nippondenso. A-B marketed and sold it as the SLC 100 and then later a newer one called the SLC 150. SLC = Small Logic Controller. In the early 1990's A-B released an all new SLC family called the SLC 500. There was a "brick" style unit that they called the Fixed Controller and then a modular controller called the SLC 5/01. They came out at the same time, not Fixed first then Modular as stated. The Fixed controller was eventually discontinued with the introduction and increasing popularity of the MicroLogix family. The Fixed controller was another brand labeled Japanese controller, but it was designed by A-B so it programmed identically to the modular units. The expiration of the labeling agreement drove A-B to develop the MicroLogix.
Other corrections:
The MicroLogix is part of the SLC 500 family and is considered a PLC, not a PAC. They were not introduced in 2014. Don't recall the date exactly but I believe it was the late 1990's. SLC products are referred to as "SLC 500" pronounced like "slick 500". Note the space. It is not SLC500 or SLC5/04. Instead, SLC 500 and SLC 5/04. The pictures at the beginning and end are mislabeled. They show a PLC-2 labeled as SLC5/02, a PLC-3 labeled as SLC5/03, and a PLC-5 labeled as SLC5/05.
And Odo Struger IS indeed the father of the term "PLC". And, he is the father of the Allen-Bradley PLC. But Dick Morley is the father of the PLC. They just didn't use that term "PLC". Instead it was the Modular Digital Controller and was eventually turned into a company called Modicon. Dick Morley's controller beat A-B to the market. Oh, and for a time these were called "PC's" for Programmable Controllers.
Hi, This is a great video, thank you. Here in Sweden i don't see AB so often. But ABB is up and coming with its AC500, the program is free to use for the basic version. This is great for beginners to start learning to program, it is based on Codesys.
What about ABBA? 😄
i know im asking the wrong place but does anybody know of a method to get back into an instagram account..?
I stupidly forgot the account password. I love any assistance you can offer me
@Bridger Cedric Instablaster :)
@Westley Titan Thanks so much for your reply. I got to the site thru google and Im waiting for the hacking stuff atm.
I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Westley Titan it did the trick and I actually got access to my account again. Im so happy:D
Thanks so much, you saved my account :D
Thank you!!
Great vid, interesting to learn about the history behind these companies, thanks for sharing.🐵
You're very welcome!
Hello sir, This is great video, I like it so much!
Realpars so great. I love this video. 🤗🤗🤗🤗🤗
Amazing!
CM Industry Supply Automation loves your video
Hi great video, congrats. I'm work at Rockwell, and just a Information: 1)micrologic is not a PAC, is a PLC.
2)now PLC5 is obsolete.
3) ControlLogix do not use Sercos network, anymore.
Thanks!!
Hi Renato!
Thanks for sharing your experience and knowledge with us! Truly appreciate it.
I think an important step of the evolution of the SLC is the SLC 100 and the SLC 150. I have a couple of 150's still alive and rocking. These set the stage for the Micrologix 1000.
Thanks for sharing that, Mark!
Amazing content . Thanks for sharing
Glad you enjoyed it!
I worked with Odo who later led the Allen Bradley Systems Division outside Cleveland. You pictured the PMC which was the first. Next came the 1774 Series, a black box with the CPU and 16K core memory and separate I/O racks. The program CRT was a heavy beast. I believe the Apollo transporter was originally controlled by a 1774. The PLC-2 then took over the product line. Systems Division expanded into CNC.
You're probably the second person I have encountered, on this planet so far, who knows what a 1774 is... and to read that you worked with Dr. Struger provokes in me a degree of awe!
I have a 1774 "Programmable Controller" setup in my living room, right here. It's a bit of a historical project for me. It's not entirely operable due to a good many failed 1774 ICs (which I am steadily diagnosing and replacing) but so far it is executing some ancient code that has survived on one of the 1774-MA modules I have - just no I/O comms, and it doesn't respond to my Program Panel (a newer 1770-TA, unfortunately I have not been able to obtain one of the authentic blue 1774 units).
I have schematic diagrams for the 1774 and 1778 series, but the real stumbling block has been the regular end user literature. I've only managed to obtain those for the '-CI2 Computer Interface (but this has been tremendously helpful). I fear all these documents have been lost to time.
I had a chuckle when this video called the power supply a "PLC".
Looking forward to upcoming videos on the AB line of controllers
Great to hear that, Mitch!
This is great video! I like it
Happy to hear that! Thanks for sharing.

Praise to the Almighty God that answered our long felt pray's for Rockwell Automation (RA) / Allen Bradley content. Its slow coming, but its progress on RealPars part. Keep us happy please. As someone that uses RA Hardware/Software, i learned quite a few things in this video as well in the back history of AB/RA.
Hi Ardent,
Great to hear that!
We are always extremely happy to hear such positive feedback! If you ever have any questions, feel free to reach out to us.
Happy learning!
Great video!
I would like to point out that the Micro 800 family was introduced in 2014, not the MicroLogix family, MicroLogix PLCs have been around since the 90s and are being obsoleted, the Micro 800 PLCs is in place to replace the MicroLogix PLCs.
Thanks for pointing that out, Peijie! Appreciate you sharing your knowledge with us.
I came to the comment section for this same reason. Thanks for the clarification. I have been working with MicroLogix systems way back in the 2000s.
Hi dear I am watching this video it's very informative.
Glad you liked it!
Very nicely explained ..Actually I just started my learning in plc programming...but as a fresher I don't understand from which company I should start working in.

@@siddharthtayde8355 ohk thanku soo much
Excellent Video! I only have one question:
PLC-2 and PLC-3 Families were never introduced into the market? Or why is it that the PLC-5 was the first family introduced into the market?
Just share some information, AB also Have small controller for support OEM , which is smaller controller than micrologix series called Micro 800 family.
Thanks then Realpars for sharing AB.
Thank you, Arya!
I think I've became decent with AB but theres always more to learn
Happy learning!
Give us one helpful tip please!
Thanks
Our pleasure!
Very interesting video. Glad to know about history of AB. Can you please make videos on types of IO module series available in AB. And which IO module series is compatible with control logix & compact logix.
Keep up the learning curve, Vishal! Thanks for sharing.

There is a PLC By AB that is not well known. This PLC was after PLC5 BUT before the Rslogix family, was called the Pyramid (?) AND it has a computer module based on Digital Alpha processor. I still belief that I have one in my old office
The Pyramid Integrator or formally known as the PLC5/250 was a transitional product. It clearly still belonged to the PLC5 technology platform, but introduced many new features that were also being developed for the Controllogix system. For instance the chassis backplane was the first AB product that allowed any module to be placed into any slot in any combination, and enabled peer to peer communication between them. IIRC it also introduced the first implementations of what we now call the CIP protocol.
It was sold in reasonable numbers to large projects in situations where the older single slot PLC5 CPU's had run out of puff. But everyone knew the future was going to be Controllogix; most of them have long been upgraded.
As for top secret AB products ... look up the PLC-4. That really was an orphan.
@@philipwilkie3239 The PLC 5/250 by itself was not called the Pyramid Integrator. Only when equipped with a MicroVAX was that name applicable. You could use the 5/250 without the MicroVAX. Many of our customers used the 5/250 without the VAX. I don't recall exact timing, but this might have been the first RA PLC that had Ethernet. I think it came out before the PLC-5/40E or the PLC-5 ethernet sidecar.
@@primecontrols1328 That's a good point Prime. All the marketing literature called it the "Pyramid Integrator" so that's the name that stuck, but in our part of the world I don't think we sold a single MicroVAX. Which is kind of a pity because there was an opportunity here for the industry to implement some nice UNIX based SCADA applications, but momentum carried us down the Microsoft path for better or worse.
@@philipwilkie3239 yeah, in a previous life I worked for A-B in a sales office, and we hired a guy away from DEC to be our guru since no one knew anything about VAX. He kept busy with one very large customer. But while several customers bought the 5/250, I don't recall any others using the VAX. As for CIP, it first came into play with DeviceNet and then ControlNet and I don't recall the 5/250 using either of those networks. CIP over Ethernet (EtherNet/IP) it definitely didn't do. It used PCCC. EtherNet/IP didn't even hit the ControlLogix until the second generation of Ethernet modules with the introduction of the 1756-ENBT module. That had to be.....maybe 2003 or so. At that time we got quite a few requests to convert 5/250 programs to the ControlLogix. You would think UNIX based SCADA would have taken off back then. Windows just wasn't up to the task.
@@primecontrols1328 I know the 5/250 only really did DH+/RIO for it's external networks, but what did it use across it's backplane? I always imagined this was some precursor form of CIP like the Controllogix backplane uses. Or have I got this wrong?
The question I can't answer is the CIP development timeline. It has to date at least from the early 90's because it's embedded into DeviceNet, and it was my impression that there was a development team (ACA ??) within Rockwell working to expand it's reach all through the 90's. Which is why I'm guessing it may have been used in the 5/250 backplane to enable the native bridging and routing it featured. On the other hand the 5/250 logic processor was a PLC5 based instruction set, which strongly suggests it would have been a PCCC protocol.
In 1999 I sold the first Logix platform outside of the USA (as I was told at the time) to a large sawmill that had about 40 nodes on a DH+. We installed a small Logix chassis with a 1756-ENET module and two 1756-DHRIO modules allowing us to split the DH+ segments into much smaller, more efficient segments, and then all their SCADA and programming sat on the new Ethernet side. It was at the time a big improvement.
Totally agree with you on Windows.
The 1400 micrologix was the best controller ever made.
please make a video on bus bar size calculation....
Thanks for the topic suggestion, I will definitely go ahead and forward this to our creator team. Happy learning!
The "Father of the PLC" is Richard E. "Dick" Morley.
Absolutely Dick led the team who built the first industrial real time controller hardware. (Incidentally that effort is a direct spin-off of the technology breakthrough from the Apollo Lunar Landing module guidance computer.) At the same time it was Dr Odo Struger while working for Allen Bradley who leveraged the electrical drawing standards of the day into what quickly became the industry's default programming language ... ladder logic. I've heard him tell the story of that breakthrough moment first hand.
I've met both men at some point in my life, both made essential contributions to that pioneering effort at GM in the early 1970's. But it was the immediate and intuitive appeal of Struger's ladder logic format which led to AB being selected as the winner of that tender process. Moreover Struger in the years before he passed away in the 90's led the team that did much of the early development work on the Controllogix platform.
Dick Morely deserves his wide recognition and I take nothing from it, but I'd argue Odo Struger should be better known as well. As for the "Father of the PLC" title, maybe they should be regarded as co-parents. :-)

Thanks for your suggestion and feedback!
Sir, I'm an electronics engineering student and I'm very confused.. whether to go with PLC SCADA (industrial automation) or not. My interest is in this field and I feel very good learning about this... But I want to know that is there good a future (with good income) in this field for electronics engineer or not?
Like everyone, I also want to earn very high... So is that possible with this option as a career?
Who so ever has the knowledge about it... Pls answr... That would be very much beneficial for me as I'm in the final year.
Thanks.
There is both a good prospect as well a good income potential in the Industrial/Manufacturing Industry or sector as a Control Systems Engineer or Controls Engineer. Basically your working Programming IACS - Industrial Automation Control Systems. Whether it be PLC's, PLC Systems or SCADA as well DCS Systems. With the Industrial sector ripe for overhauling from old systems to more modern as part of Industry 4.0 there is huge potential for engineers that can do Control Systems programming as well very knowledgeable of industrial controls and other software programming.
At least try to learn Rockwell or Seimens Systems as the big two and or better yet both which gives huge flexibility. Yet, learning some other systems as a backup is helpful as well for flexibility in what you can do. Also learning some Networking skills will be invaluable as many these systems are a network in their own right often isolated systems from the internet but in today's world are increasingly becoming more connected within companies to enterprise systems more increasingly. That poses a challenge in its own right and dealing with IT Personnel. But learning some good Networking skills can help. Make sure to watch the other RealPars video that talks about career options in the automation space: th-cam.com/video/rJvThzbMmHE/w-d-xo.html
@@ardentdfender4116 thanks a lot sir. I wish you good life and health ❤️ this explanation literally meant a lot to me
@@mohitbhatt784 I will give you an extra bit of information if it can help you in your prospects. I work for an Indian-American company that's an OEM and all our systems are in Industry at Power Plants or Energy company's Plant Site. I started as a Process Operations guy but moved over in my company into Field Service and Comissioning. The person I work for is an indian guy who is the Process Automations Engineer and Programmer. His original background coming from India was in Instruments Control. However he is a highly intelligent guy that I have worked with over the last 6 years together doing numerous projects for plant systems PLC Systems Upgrades. For me that was how i really learned PLC coming from Process Operations. However, what I have said before Is based on the Engineer I personally work with and he is a really damn good Engineer, Programmer and Control Systems Engineer all together. He knows Rockwell Systems Hardware very well, some Siemens and Ignition Software a little bit. What makes him good is he knows how to come up with solutions to our customer problems that other companies think hard to find a good easy solution.
He also got his CISCO CCNA for Industrial CCNA and that made him so much better in understanding Networking of the industrial systems. Rockwell has a CPWA Architecture that they recommend for proper design of good systems or when upgrading also. Having his CCNA was not or is not required by my company. But he persued it and got not only his CISCO CCNA but also his Industrial CCNA both. It allowed him greater understanding of design concepts and understanding to do his job on a huge scale. Again not required but extremely helpful. He started way back as just an instrument guy. But at the end of last year in 2019 both him and i did the largest upgrade in our company history in New Mexico at a power plant where he totally upgraded and rewired a 15 Node PLC System at a Power Plant in just 3 weeks and with minimal issue. He architectured the entire project. So the prospect as a Automations Engineer is huge. But its what you learn as well along the way that helps to make you better and in prospect to whatever job you choose to do. The future will be where you can sit on your laptop with much the software needed to do your job remotely and do programming with some travel. Wish you well in your future.
@@ardentdfender4116 can't thank you enough for your these efforts for me (an unknown guy) sir. You are such a humble person. Thanks a lot for typing this much, and most importantly, taking out your such a precious time out of your busy schedule to make me understand. Really, thanks a lot.❤️

what is difference between plc and pac..?
Hi Divyang,
Thanks for your comment, this will make for a great topic suggestion.
I will go ahead and pass this on to our course developers.
Happy learning!
@@realpars Thanks for the response...
love from india 🇮🇳
The video is well made and easy to understand, professionally narrated, undoubtedly their lessons must be real good. However, I'd like to point out a few things: The Micrologix is not a PAC, as shown in this video. It fails to mention the PLC, the first that Allen-Bradley sold, which is significant because it really was the very first. I was trained on that first PLC and have been working AB's PLCs since 1980. It used to be the best and easiest to work PLC in the world, but not anymore. Considering only the Studio 5000, it has a miriad of versions running in industry, each one with flaws and bugs particular to each version, even sensitive to operating systems it is run on. A real Babel tower. There are far more issues making things more complicated. Granted there are things that are made easier with AB PLCs, but not too many.
Thanks for your sharing your knowledge and perspectives with us, Antonio! We appreciate that.
Antonio, you seem well experienced with Studio 5000 and its flaws but to be honest it happens with all manufacturers at some point. I completely agree that working on PLC5 or SLC500 is far easier to get around than working on some of the newer PLCs due to complexity but many features have been introduced. I really recommend you to take a look at Micro800 family, expecially micro850/870 as its programming software is more user-friendly and resembles the vision behind RSLogix 5/500. Granted it doesn't have many options CLX/CMX has but still is good/not expensive variant.
Back to Studio 5000 - versions can be little overwhelming and it should be overhauled- I get that point. I do believe with newer approach to more IoT based systems it has potential to be changed to more friendly version.
@@Rotaldy What you say is true, however. with such a complex (and expensive) suite of products, you would expect a far better support (which lefts much to be desired) and you, as user, end up being on your own. And you end up paying until it hurts for said support. It may be great to keep your SW up to date, but that is the end of it. I lived through more than one bad experience when requesting support. What support suggested was carried out without the problem being solved, after $5,000 were spent. One of the good experiences I had with tech support was back when it was offered feee of charge. Many of the other manufacturers, specially the less known ones, do not have many of the features the logix family has, neither the support, and most of the time you end up on your own as well. As I said, there are many things that are possible with (and only with) Logix PACs, which I like very much. But many of the customers aren't willing to pay for the expenses incurred when AB is offered. As for the Micro 800, the free software provided is not exactly friendly. I do not know if the paid version is any better, but is similar enough to other brands, as if AB's had a regression. As for functionality, it is OK, it does the job. But then again, so those other less known brands do. Thanks for replying to my posting.
Although siemens is a good plc. ab owns north america.
The plc 5 is obsolete. Also the micrologix was released in 1994.
