Hey Tim! Hope this message reach you well. Love the video. Can you explain to me why you would use this method of sequencing over a GRAFCET? Can you give me a few examples of the benefits of sequencing with a ladder program as opposed to a grafcet? Thanks again Tim!
Yes, a very important reason. I get to look through LOTS of programs that people send me and I have only seen a handful of programs that have used GRAFCET or SFC. It may be the best method, but if technicians are not familiar with it then they will not accept it. The further I get in my career, the less likely I am to use the latest and greatest and the more likely I am to use basic methods that can easily be understood and can be used in any brand. Here is the who livestream showing many other methods and I talk about it more in it. ruclips.net/user/live8CGEp4LZGfE?feature=share
(From the same viewer using a different RUclips account). Oh, that make sense. I never taught about the fact that more experienced technicians might be "set in their ways" and prioritize ladder for sequencing. I'll look at the video again and try to integrate that method (even tho I am still partial towards Grafcet).
I'm not saying you shouldn't use Grafcet but just giving you something to consider. I don't think most programmers take into account the training cost of learning a new language. In the video I referenced earlier, skip to the SQI/SQO section which when I was coming up was the "correct" way to sequence machine steps. The maintenance manager who saw me use it told me if I used it again, I wouldn't do anymore work there. It wasn't a matter of their technicians being "set in their ways". It was that it wasn't 100% universal across platforms where as most of the other methods shown in that video were. I don't know the training cost of a new languages for technicians in a plant but is is over $100,000 to train the technicians in a plant on a new brand of PLC. That is why I chuckle every time someone post that they saved a company thousands of dollars on a project by using a different brand than the company normally uses. Gracfet is on my list to make some videos on but just to put in in proportion, I get about 400 questions a week and I think you are the 3rd person this year to ask about it.
Thanks again for the feedback. I'm currently enrolled in an automation degree in a French Canadian college and my teachers seems to priorize using a "command grafcet" to manage their sequencing and then refering to the steps of said grafcet in a ladder program (ex of ladder rung: If start button is pressed and the x.auto step ofthe Grafcet is active (NO contact x.auto.x) then the green light goes on). I appreciate you showing another way of doing it as I assume that the reality outside of school might differ from what I am being taught.
One thing I state in numerus videos videos is to never argue with your teacher :) As you start running into equipment, pull the program out of every PLC you can and see the different ways different programmers do things. There is no true right or wrong method, what is more important is that you understand the different methods because as you start out, you will spend much more time modifying and troubleshooting other peoples code than you will building new equipment.
Hi Tim, I have just found your videos and am really enjoying them. I teach PLCs to apprentice electricians and have a lot of experience with PLC-5, SLC500 and Control Logix. However I'm now moving to Micro800 and Connected Components Workbench. I have found the Master Control Relay instruction is missing from the Micro800. Do you have a video or CCW master control relay solution? Cheers.
Hi Simon. Honestly I think the MCR instruction makes troubleshooting difficult and am glad that there is not equivalent for the MCR instruction in CCW. I talk about some of the issues with the MCR instruction in this live stream. ruclips.net/video/xnQUI2q5s-U/видео.html
Here is the original video but the Studio 5000 version was done in our training class. It should give you some context of how these methods transfer across the platforms . ruclips.net/user/live8CGEp4LZGfE?feature=share
Hi Ali. It depends on what brands you think you will be working with but since this is an Allen Bradley video, I would start with this PLC trainer. Feel free to reach out to me with additional questions to help you select a specific model. twcontrols.com/plc-trainers/tw-controls-allen-bradley-micro800-plc-trainer-sku-trn-bas-micro820-aio
Sir, please Mack a video about Micrologix 850 for serial port data reading over RS-485 network interface from any selve device. ... please sir help me ....... THANKS & ❤️ From INDIA.
very helpful series thanks alot
You are welcome :)

Hey Tim, where can I find the original video that was made with studio 5000?

Hi Tim .I am new in PLC I would like to know which PLC I need to buy to start doing basic circuit. And let me know where I can find it. Thank

@@TimWilborne ok thank, How much it is.
Hi Tim. How did you become so knowledgeable? Did you go to school or on the job training or both?
Mostly on the job training and a lot of hard knocks!
Sir, please Mack a video about Micrologix 850 for serial port data reading over RS-485 network interface from any selve device. ... please sir help me ....... THANKS & ❤️ From INDIA.
We have some serial videos planned.
Thanks 🙏
