In the previous video (Part 1) of this Siemens PLC Training course, we configured our PLC hardware in TIA Portal V15.1.
👉 upmation.com/plc-hardware-con...
In this video (Part 2), we are going to write a PLC program in Ladder Logic (LAD) for a simple "water pumping system".
👉 upmation.com/ladder-logic-plc...
In the next video (Part 3), you'll learn how to simulate our PLC program using the PLC simulator.
👉 upmation.com/simulate-the-plc...
In Part 4, we will continue our PLC programming journey with another simple, yet practical PLC program.
👉 upmation.com/plc-program/
Before we get into PLC programming we have to know what the logic behind the industrial process is. In the real situation, there are some documents for this purpose, such as Philosophy of operation, I/O lists, Piping and Instrumentation Diagrams (P&IDs), Internal wiring diagrams, and so on.
We will learn about the Control and Instrumentation documents, and drawings and how to design and draw them in software such as EPLAN or AutoCAD electrical in future videos.
In this Siemens PLC programming tutorial series, we will write some Ladder Logic PLC programs in the Siemens TIA Portal for some simple but real-world processes.
We start from the simplest PLC Programming examples and will grow to the advanced levels. You will definitely learn some useful tips and tricks in every single example that you can use in your automation projects.
You do not need any actual hardware to participate in this course. So having a laptop with a TIA Portal installed on that would be enough! In most of the examples, you can use Step 7 and WinCC as well.

interesting the video. Simple and pleasant. For my part I would add two input variables. One coming from the thermal relay of the contactor, to turn off the system and turn on a pilot light and the other to select between automatic and manual. Congrats

Can i ask why didn't you use OB35 for this project? Was it because the plc program didn't need a quick update cycle?

Better to use P or N switch in this scenario. SR stands for set and reset, so i was learnt to not use classic NO and NC contacs because they are not pulse. I think because of some bug, so its more reliable.

[@Upmation]

Hey! Thank you for the input! But We normally use P or N, for the signals that are naturally Pulse type and we want to get their inputs throughout their Positive or negative edges! In my experience using FFs does not causes bugs.

[@LC-qi5ff]

When the low level switch senses water won’t it turn off the motor?

[@Upmation]

Hi Li, the short answer is no! I believe you are assuming to turn on and off the pump only by means of the low-level switch (and you did not consider the high-level switch). In this case, the motor-pump will turn on and off intermittently and frequently IN SHORT PERIODS of time. This will lead to the motor breakdown very soon or the system will fail due to the frequent mechanical stresses (Of course, the motor thermal protection will shut down the motor before breakdown!). According to the scenario @1:12, after the HLS turns off the motor, we have enough water in the tank for some time. So the motor will remain shut down and will rest until we are in a lack of water in the tank again. In this way, we increase the period of ON and OFF sequences. I hope my answer was clear enough! Let us know if you have any other questions.

[@LC-qi5ff]

@@Upmation Thank you so much for replying. So how does the pump fill the tank up to the high level if the tank LLS switches off the pump when it senses water?

[@Upmation]

Hey Li, you're very welcome! As per my explanations, it is the High-Level Switch (HLS) that turns off the pump as soon as it senses the water (to prevent the tank from overflowing). On the contrary, the LLS will turn ON the pump when it DOES NOT sense the water (to fill the tank). By the way, if you watch this video about NO and NC contacts, it may help you more on this subject ( kzbin.info/www/bejne/qqm4k5yglth2kLc ). And please reread my previous reply and let me know if you found out your answer or not.

[@LC-qi5ff]

@@Upmation Thanks, I think my understanding of flip flops or latching relays was wrong. I think I get it now but correct me if i’m wrong: the output does not rely on a continuous pulse (1) from the set or reset inputs. So the pump will remain on after the LLS senses water (and the NC contacts in the program open), until the HLS senses water (and the NO contacts in the program close, causing it to reset the output).

[@Upmation]

@@LC-qi5ff Just as you said! We should not confuse the real (actual) contacts with the NO and NC contacts in the software. As you explained, when a switch (LLS for instance) is open and not sensing the water, then its corresponding NO contact in the software (I0.1 for example) is OFF! and at the same time, its NC contact in the software is ON and therefore the Flip Flop (in the example) is "Set". and vice versa... We'll have pointed out this, in another PLC programming example which is going to be published in December.

Hi youtube, can i know the components that u use? My college final year project want to do this. ^_^

Hey! What do you mean by the components? If you mean the software, that is TIA Portal V15.1.

[@jiarong1966]

Sensor and motor

[@Upmation]

@@jiarong1966 For the sensors you can consider them as Floating level switches. and consider a 20KW electric motor. However, these are some assumptions and can be changed from one project to another.

[@jiarong1966]

Thk for your reply^_^

[@Comedy_lover25]

please name of this software ....

[@elektromeha]

Why would you talk about using all three switches as NO and then taking from 'Instruction' tab NC and placing them for two low levels? 5:17

[@Upmation]

Using a physical NO contact does not mean that we should use the same thing in the software. The tank LLS is a physical NO contact with the I0.1 logical address in the PLC software; when the level of the water is higher than this switch, its physical NO contact is closed and the I0.1 is active. So, we use an NC contact for I0.1 in the software to say the PLC that whenever the I0.1 is NOT active do this or that! (In this case, start the pump cause the level of the water is lower than the LLS). I hope you got what I mean. But I strongly suggest you watch this video as well: kzbin.info/www/bejne/qqm4k5yglth2kLc

[@tipsinvestments9460]

but will the water level change the position of switch physically and what happens if you loose power when the water is half the tank
