PLC Programming Tutorial for Beginners_ Part-2
• PLC Programming Tutori...
==========================
In this lesson we will learn how to write a PLC program using an "S7 300” PLC and “STEP 7” software.
We have two pumps which are being used to transfer two separate liquids into this tank.Inside the tank there are two level switches installed in the lower and upper parts of the tank respectively.
There is also an electrically powered mixer inside the tank which starts working for a defined period of time, mixing the two liquids together after the tank has filled.
We also have a discharge valve in the bottom of the tank which controls the draining of the liquid from the tank.
When the level of the liquid drops to the level of the switch's position the contact closes, sending a 24 volt DC signal to the PLC input.
We want to write the program so that when the level of the liquid reaches this minimum, the pumps will be activated and begin filling the tank with the liquids.
The pumps continue filling the tank until the level reaches its maximum at the higher level switch. When this happens the open contacts in the switch will be closed and another 24-volt signal will be sent to the PLC input telling us that the tank is full.
When this signal has been sent, first the pumps should shut down so that no more liquid enters the tank, and then this mixer should be turned on.
We want the mixer to operate for seven seconds, mixing the liquids that have been pumped into the tank.
After seven seconds the mixer should automatically shut down and this discharge valve should open.
With the valve open the liquid will be discharged from the tank and transferred to another location within the factory to be processed.
When the level of the liquid in the tank drops to the minimum set level of the lower switch, the switch contacts will close again thus starting a repeat of the cycle!

I am working as maintenance engineer for 4 years. I am learning PLC programming by following your tutorials. Thank you brother.
Am an instrumentation graduate but I am working in construction field isted of maintenance could u please help me to get a job in maintenance field...
Oh sir I m Ethiopia I live city jigjiga I requested this campnay the manager accepted but unfortunately I miss my payment 😭
@@cribels9832 Skillwork, on indeed. They will get you into a maintenance position.
Sai can I contact you i wanna know more about it
@@madfrosty5228 Don't know if you still have that question but the counting goes from 0.0-0.7 then 1.0-1.7. So there is no 0.8 and 0.9
I remember getting a taste of this stuff when the processing room I used to work in was getting retooled and programmers were working to get all valves, mixers, sensors etc. operating correctly. I as a lowly operator got to see that. Never knew how much went into programming something simple as turning a mixer on or off.
Excellent clear explanation
Rodrigo, We're glad you found the video helpful. Tenha Um Bom Dia!
+RealPars could you explain how are you chosing hardware that you are using? Are those elements you work with in real work? Are they somehow better then others?
Hi there, Sorry it seems like we have not been notified for this comment. I know it's too late and you've have probably found the answer to your question but I'm answering this hoping it can be helpful to others. The PLC hardware that we use depends on the specifications of each project. For instance, when you have 12 digital input signals, you need to select a digital input card that has at least 12 inputs. In this case you can select a 16-point digital input card and use the additional 4 inputs as reserves in the case you needed to connect additional digital input to the PLC in the future. So the type and number of signals that you have in each project determines what PLC modules you need to use. The PLC hardware that we use in the software are exactly the same as the hardware we use in the electrical enclosure (the real world environment). I hope this help. Let us know if you have more questions.
Hello RealPars, im azhar from Indonesia'. Im your subsciber. GodBlessU. Im Programmer for PLC. i want to have permite from u to re-upload your Video every part using Indonesia language (bahasa). If u permite me'. I will very happy. Thanks

Glad you found the video helpful!
Very very helpful video thank you sir
I’m newly joined in a Switchgear firm as design support!!!
Really needed video
thanks bruh, i rarely subscribe to any channel that i usually watch... but yours really help me, a fresh graduate to learn instrumentation... god bless you
Thank you, your video is very helpful!
Very good. I have no programming experience and was able to grasp the concept easily. We use PLC's extensively and I wanted to get a grasp on how they're programmed. It's always been interesting to me how these are set up.
Great to hear that our course videos are so beneficial to you. Happy learning!
For the beginners,this video is very valuable to learn,thanks a lot.

Excellent Explanation. liked it, thank you so much
I have an interview for a job to work as a controls engineer. I didn't pay attention in college and have a degree in aerospace engineering so that's why I'm here.
We're glad that you're here! Best of luck on your job interview!
Didn't pay attention in college but have an aerospace engineering degree. Hahaha. I bet people hate you
@@realpars I accepted the offer, video helped me with a question they asked. Thanks bud.
@@nicko9725 not really I wasn’t a great student, I got mostly B’s, I have a solid 3.1 CGPA
AllTheRage That's really not bad, especially once you consider the curriculum for that degree: calculus, physics, etc. I was the same way in HS and my first time to college and people hated me for it. Congrats on the job bud!
Thank you so much. Your videos really helps.

could you make videos for classsic control
Hi Omar, Great to hear your positive feedback! I assume that by "classic control" you mean creating videos on theory of control, formulas and stuff like that. correct? If so, I should say we're now more focused on practical side of things.
Thank you.
great video I am a student of industrial engineering and systems , has helped me a..... greeting from Mexico

I hardly know what you're doing but this seems very simple to learn. I am looking for things that would interest my 14 year old son. I have a very basic understanding of how a PLC works, I'm more of a math and science kinda gal. But, I've always told people, make your computer do your work for you!👍
Hi Anita,
Thanks for your comment!
Amazing that your 14-year-old son is interested in PLC's. We have a free course on PLC Hardware that might be of interest to him, bit.ly/2XnnUrF
Feel free to check it out! If he has any questions along the way, he can always leave them in the comment section below each video course.
Thanks for your work. Good job. 🙏🏻
You are very welcome, Erkan! Thanks for your support.

Thank you! very good
THANKS I GET GREAT HELP TO LEARN PLC .BEST REGARDS.
Good job
Love you guys!
very simple to understand
Great presentation! I will watch more!👍
Great! Happy learning.
My Senior Design group is trying to create a very similar application to this. The video was very helpful in determining what we need for PLC inputs. Do you have any recommendations on actual sensors that would operate similar to your high and low level sensors? We have found different proximity sensors and weren't really sure what to go with. Whatever you had envisioned for this program would work perfectly for us.
+Chris Daughters There are different brands for level switches you can choose from. We usually use "endress hauser" or "Rosemount" for our projects. Take a look at the following links:

Incredibly good explanation. Thank you very much for the video :)
Many thanks
thanks foe knowledge sharing
Janaka Kavinda My pleasure!
Great video tutorials! Could you please explain or refer to your videos on how to know it is 16 inputs ranging from I 0.0 to I 1.7! Thank you!
The inputs are identified by bytes, with 8 bits per byte. A 16-point input card requires 2 bytes. The first 8 inputs are in Byte 0 and are inputs 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7. The second 8 inputs are in Byte 1 and are inputs 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7.
Love this theme, thanks
Jean-François
You're very welcome!
Happy learning
Sweet!
Thanks for this. I got a feeling that sooner or later, I'm gonna go through this stuff. Lol
thank you very clear
Sir, Super Explanation....Thanks...🙏

Super training
Thank you for sharing, very informative and useful thumbs up 👍
You are very welcome, thanks for your support Darrel!
@@realpars you're most welcome ☺️
Good one
Wow Great 😍
Please I need your advise , I have a project where I am expected to come up with a diesel dispensing system such that the pump to discharge diesel discharges an amount of diesel based on how much of diesel is needed at that time just like typing in 2000 liters to be discharged in a storage tank , a good example is a fill station dispensing unit . Now we have on ground a pump , a flow meter and a batch controller but a solenoid valve , a valve and a manual valve to be installed just before the flow meter in case we need to carry out maintenance on the flow meter . now based on the work philosophy my question is what kind of solenoid valve and valve can you recommend I use for this processes as the solenoid is meant to actuate the valve so it will closes ones a certain amount of product imputed has fully reached its final point ,and the pump is cutoff immediately the solenoid valve actuates the valve and it closes to avoid further flow of the fluid down the line .
thank you... great tutorial.
You're very welcome, Jorge!
Really good content guys keep it continue. ❤️❤️
Thanks for your support, John!
Your videos have been very helpful, thank you. I have a question regarding the graphics display, please can you explain how the graphics display interact with the plc program? Also, how to build graphics display in PLC?
Hi Gena,
Thanks for your comment, and that's a great suggestion! I will happily pass this on to our course developers. Hopefully, they are able to create a video courses covering that, in the future.
Great video sir! Thank you!
Glad you enjoyed it!
this video is great for all
I like it , it is really good
Simple and best lecture. Many thanks
Gopendra Pratap Singh You're welcome!
In real production high level switch should on NC contact because is wire is damaged or sensors tank could be overfill
Don't forget the low level switch! And there should also be an emergency halt/shutdown routine in case both contacts are open.
Cool and nice explanation, I have a problem maybe you can help me out. At the ob1 programing window I mis all the yellow folders like bit logic. I only have the New network, FB, FC, SFB and SFC Blocks, Multiple instances and libraries do you now how i can add them Thanks .
Great tutorial instruction video. Thank you
Glad you liked it! Thanks for your support.
very good visualization
Really nice video and very helpful By the way How can I get the PLC software same as you using in this video? And Can I use in window 10?
