I am a teacher and a student of effective communication, esp. of the most difficult and challenging "simple concepts”, I find the PLCProf to be SPOT ON. The great teachers in my life are much like this man. He obviously cares about his subject. Teachers who are "fast-talkers" will have left students that already have a good grasp of, or don’t care about, the message. Students in THIS man's class will have confidence they have the info needed to proceed. DD's 3rd yr Elec. Majors love this too.
You have helped me understand PLCs. I am ordering your material. You are a very good person by sharing and teaching your knowledge . I always play your channel and enjoy listening to you. Thank You
I have been watching now 5th video and I basically like it more and more. PLC Professor know more the other videos and what is the best about all presentations is that he talk slowely.clearly and understundable in each part of video. I learned more than from other difficult books and videos. All the best Professor :)
Ive started a course in PLC training and they shoved a book in my face and said off ya go. Ive just gotta say how appreciative I am of your videos. They have explained a lot that I'm sure I 'might have learnt by reading, but your videos make the process so much more easy and enjoyable.
I shot many of the clips several times and finally made a judgement call on whether or not there was enough of the intended content viewable even with shots of the back of my hand. I am starting on a video today that covers just enough basic electricity to slide the beginner into a basic understanding PLCs.
PLC Professor. I have watched v1.0 thru v1.5 bac-to back and loved every moment. Loving this video too. You have done a really great job. Been thinking of purchasing your learning lab/ Rockwell 500. In any case it's really been a great help.
What always puzzles me are people who go to RU-vid for something FREE and then complain. Please do not waste your precious time on something that is unpalatable for your high intellect. My videos are not for you. I think that you should make a video showing how it should be done and I will watch yours.
Dry contacts are not polarity sensitive. We pick one "row" of lugs to ease soldering a straight line for a common. You could use any of the three, if it is a spdt type switch. The center lug is literally designated the common for the NC/NO contacts.
which model uses 24dc for both inputs and power supply? my micrologix1000 is 24vdc for inputs but 84-240vac for power supply, which is a little dangerous for external termination
Two reasons for using the L10BWB: least expensive considering a $7 24vdc wall wart (power adapter) or any unit with DC Inputs for safety reasons, you are correct in your assumption.
You would need to find the documentation online to compare the pin outs and connector configurations. Most RS232/USB adapters will work. If you go online and type in the part numbers, you will find the cable and adapter together for less than $25.
Each NO momentary pushbutton would be connected across the two pins used on each toggle switch as an alternative to closing the toggle switch and immediately switching it back to the open position. This would require two conductors connected to the input specific connection. This would not be good for the soldered pin do to overheating the pin and melting the plastic switch body.
I believe so but not required, you just need a toggle on/off and use just one set of contacts even if they are DPDT. In my new design I am wiring NO momentary pushbuttons in parallel with the toggled contacts allowing an easy momentary closure without actually having to toggle the switch. Since they are NO, they do not interfer with the toggle switches. Have fun: Tim Gates
For those of you interested in producing videos, I used two over the shoulder bright flourescents, a point and shoot Canon on a tripod and stitched the eleven clips together in Camtasia Studio from Techsmith. When recording closeup, such as soldering, it is almost impossible to not block the view on occasion without the help of an assistant that can manipulate the camera position and angle. Also, this point and shoot does not offer zoom during recording. More than one camera would have helped.
The reason that I recommend the BXB is that it requires 24vdc primary power which you can get from a power adapter. This prevents exposure to 115vac. Always, with any project, the first thing that I do is go to the mfg. site and download any documents that I can find for the components that I am going to use. If you type that part# into google, you will find the documentation and instructions for use. Make it a practice to do this, I have and it helps considerably.
You are right that these are on RU-vid, but I don't understand "Playlist". There are videos to the right side of the page, but how do I find only yours? I may want to see others but yours are the best I'm finding, and I've used PLCs since the PLC2s were new. Thank you so much.
The 120 volt version is probably the cheapest option because all you need to power the PLC is a piece of lamp cord with a polarized plug on the end of it.
Hi Tim. Thanks this is a wonderfully done video. I appreciate the time you took to throughly explain the steps to build this trainer. I was thinking as I watched about just what you say above about having the momentary NO in parallel. Do you have a diagram showing the wiring for that? I could probably figure out with enough time but if you have it, that would be great. Thanks again!
Everything is AB (Rockwell Automation) across the board. Each controller mfg. has there own proprietory programming software app. Once you learn one brand, the others are easy to pick up relative to the quality of the programming software app. RSLogix500 is one of the easiest for beginners.
I have never seen any thorough lecturers. It's an amazing work. I used your lecture RS LOGIX500 simulator to install into my pc, it's was supper it's cant any clear. I was wondering whether you have any videos on how to connect the actual plc configure it and download the program to the plc. It will be much appreciateed
Hello PLC professor - I notice in the video that you use switches that have 3 terminals on the back of the switch and you only use 2 terminals. I notice on Ebay/Amazon that "Toggle Switches" come in a multitude of variants: some with 2 terminals, some with 3 terminals, or more. Some of them, say "On/Off/On" as opposed to just "on/off", which is what I believe you were using, though you don't say that explicitly. Can you elaborate on the switches? Thx
A maintained single pole - single throw SPST will suffice or a SPDT, single pole, double throw. It needs to be maintained (not spring return); avoid center off switches. You only need one set of contacts that you can turn ON/OFF...but you can use any switch that will yield that function and the remaining contacts are unused.
I'm assuming you used an Allen Bradley Micrologix 1761-L10BWB PLC for building this lab trainer. I imagine that a 110V model like a 1761-L10BWA PLC would not be safe as a lab trainer because of the 110V being brought to the screw terminals (and you would still need a 24 volt supply for powering the DC digital inputs). Also, would other PLCs in the 1761 Micrologix family such as the 1761-L16xxx, 1761-L20xxx, and 1761-L32xxx be appropriate for your labs?
Looks like it's only free with the 10 and not the 16. At least with the 16 you can only run it in demo mode according to the manual. I've also noticed that the bxb is at least $100 more on the used Market as opposed to the BWB. Can the BWB not also be run on 24 volt alone?
I don't think that it will matter. But, if you are using a 1200, then you must have access to a license of RSLogix500 that will work with the 1200. The free version only works with the 1000 and the 1100. Good programming: Tim Gates
Hello Professor: I like your videos. Each of your viewer's don,t have your materials but happens to view this video. I think this video is not intended for them. Right? In this case, I think, You need to explain how this trainer module is going to work. I am yours thankful.
Although i havent gone through all your lectures as of yet, I am building this setup, with 110ac micro 1200.. was going to follow the same procedure, but add small indicators lights and wire to outputs, will this screw with the tutorials? or is it a good thing? Great series for what i have been through already! Thanks in advance
somewhere on the page should be the word Playlist. However, if you look for RSLogix5000 you will find one that also says multiple programs something conveyor
Thank's for the videos Great job. Could you answer a dumb question of mine I would like to know if plc cables hm02 and pm02 are interchangeable? if so can they be adapted to usb without a huge fuss. Kep up the good work Thank's
Ok I'm a poor maintenance tech that has some control logic background and looking to learn plc's. We have micrologix5000 at work however If I understand correctly to save some money I can start learning with the micrologix1000. I have the m1000 now and prefer the experience of building everything myself with your online videos so thanks for the info. Once the build is done will order your books / videos to study. Question is once I have a grasp of the ladder logic and programming with the 1000 what will the expense be to learn the m5000. I will have access from time to time at work but to speed up the process would prefer to have home study also. And thanks again for publishing your knowledge. Trying to get more into the plc side before 50.
You will have to have CompactLogix or ControlLogix hardware at home as well as a license for RSLogix5000. RSLogix500 is inexpensive to learn, not so with 5000.
One other question. Concerning the power supply, I found a 24VDC/250mA power supply (70235K81) on McMaster-Carr. My questions are: Is the 250 mA sufficient? and How can i tell if this PLC requires center positive or center negative? Thanks in advance James
Hello Professor, lets say that I would like to add pushbuttons also along with the switches. Since there are only 5 input terminals how would I go about wiring the pushbuttons in the plc?
Plc professor, hey how are you? Are you still supplying the training manuals by any chance? We’ve a skill shortage within our organisation relating to legacy AB plc since our migration to Mitsubishi. Also, would you ship to the uk? Best Regards
Great video professor. Since its been a few years now, do you still recommend the same brand and model? I am looking for a PLC unit that is easier to program as I am new to operate a conveyor belt. Any economical option you recommend? Is there any website that you recommend to purchase from? Thanks!!!
We do not offer a kit in the Bookshop at the plcprofessor website, but we do offer the prebuilt and the manuals. Some of the videos have the website address on them, you cannot put a website address in a reply. We may offer a kit in the May or June timeframe.

Thanks professor. I will buy the books the materiak looks awesome. Can this lessons be applied to the slc 500 ? Regards
Dennis Javier Buján González There is very little difference between the programs in a Micrologix and a SLC500, You will have problems going to a SLC500 from learning on a MicroLogix1000/1100.
Dry contacts are not polarity sensitive. We pick one "row" of lugs to ease soldering a straight line for a common. You could use any of the three, if it is a dpst type switch. The center lug is literally designated the common for the NC/NO contacts.
In general, its a sequence of events. Like a Drilling mill using limit switches, . Im really having a hard time at school. Our proff does not even teach us he just lets us sit in front of the allen bradley and read the book.
dukeskylar Go to the plcprofessor website and buy the Complete PLCLearn Series manual, watch the playlists on this channel, do the labs and you will get everything that you are looking for. The is an entire lab just of sequencing.
I was just looking at the Allen Bradley website and getting ready to purchase the MicroLogix 1000, but found they are discontinuing that platform and recommend migrating to the Micro820 PLC Systems or Micro830 PLC Systems. Is this a problem for someone who is going to get started on all this business? Thanks in advance.
+djl Very few people like the Micro800 series and it is not a good platform to learn on, especially if you ever want to learn RSLogix5000. All of the Micrologix processors use the same software and there are many Micrologix processors that will be around for a long...long...long time.
Totally dependent upon the output circuit or the output modules circuit. Manuals for any of the I/O are accessible from the Mfg. website.Careful!!! each point has a maximum but the module as a whole is not equal to the number of points X max for one point.
Hi,i'm an electronics technician,for the last 30yrs i've been dealing with spinal injuries and juggling vacuum tube amplifier designs(i play guitar) as a sort of hobby,i'd like to get into PLC,i down loaded the RSlogix 500 emulator ,would the books you have in this video be compatible with this emulator software?.
Download the manuals from Rockwell for the processor that you are going to use and look at the voltage range for the inputs. I do not remember what the range is; we just always use 24vdc.
Thanks to watching some of yr training video , currently we are runnning a production line , and like to startsome simple PLC programme, can you highlight me of how to start with from ,type of LC logic control ? thks
khiev rotha It might be available on the Rockwell website. You would have to register and search for free downloads, micro starter lite. You also need RSLinx Lite. They are on a disk that we include with lab stations and kits.
where can i get the software? I was not able to download the rslinx or rslogix (just FYI, i did hear mention that it was free @ around 2:45 in the video)
The standard control voltage for industrial panels is 115vac or 24vdc, both for the field devices and the controllers themselves. All electronics requires DC, if there is an AC connection it them must be rectified and filtered to 24vdc.
