🤔 This was really awesome from a junior programmer in Automations Controls perspective having watched both videos part 1 & 2. Clearly demonstrated from opening the program, setting the project configuration, clearly showing which exact buttons and tabs etc in configuring the logic controller setup, then clear details how to exactly configure the logic for the system. This should be applauded because many people just say but don’t actually show in details for someone learning and following along and you can be confused as to which button they clicked or drop tab for something. This 2 part video was very well explained and I’ve never even used Siemens Step 7 Software. Well not yet. But this tremendously helps if I did have it in understanding how to setup a project and configure. My 1 only suggestion would be in a future video if possible to use the very same tank, pump system and do a video using Rockwell Studio 5000 with ControlLogic controller in the same detail. As well in same video add a logic version maybe in simple Function Block programing demonstration of same logic for the input/outputs so any newer person learning can clearly see both versions of the logic programing in standard ladder and or including if using Function Blocks.
Thanks for sharing your thoughts and knowledge with us, Ardent! Regarding your topic request, I have forwarded this to our creator team to add to the list. Thanks a lot!
This fall (2021) I'm going to school for CNC certification, my first class is industrial robotics and PLC's I wanted to have an idea before I rushed in blind, and these videos are teaching me more than I could have hoped for. Thank you very much.
I was just introduce to PLC yesterday, and all I can say is that your the best. Please more video on how to use the various tools on processes will be appreciated
Hello RealPars... You are the master of PLC... I am new and very interested with the system like programming... i like to works with my laptop... Very easy to understand... in hopes you are doing class in Malaysia... Really appreciate it... looking forward for continued relationship...
Thank you for this tutorial! Gave me a good start in my Simatic PLC training. I do have one comment to make about it, and maybe you can clarify this for me. The two sensors (H_Level and L_Level), L_Level will always be active when the product is in the tank and approaching H_Level. When the product reaches H_Level, L_Level will still be active. This will make the SR Latch useless and it should instead be a JK flip-flop. Anyways, thank you once again, it does give me a good start on how to use the software and what can be accomplished using it! The animations were very helpful.
Appreciate the explanations you provide, some of us are moving into supporting this equipment from working with other larger gear and no training on even simple programming.
its very nice video. i do have a query related to network 3. you have used IO.1 high level as a input for valve which will be high or 1 or NC when fluid level is at max and then only output side of valve will be 1 and allow water to discharge at other place. but when fluid level is in the middle level during discharging time then input IO.1 will be low or 0 or NO then output side of the valve will be 0. Then how valve will be remain open to discharge rest fluid?
Nice content, thank you so much. Only question is: why in this case NC contact of Stop switch is used(signal is present in reset input of RS flip flop? Looks like in order to make system operate “Stop” button should be pushed all time long. Thank you.
Thank you RealPars. I think there is a mistake in the last step of the program. The 'stop' button must be modeled as a normally open contact in the program, or if we want to model it as a normally close contact, we should put it in series with the contacts in 'reset' signal path.
The FlipFlop is an SR type. Does it give preference to the SET input or RESET input when both are energized? In your example the SET was energized and then you have clicked on RESET. The pumps turned off , so it gave preference to the R input. Does Siemenes have a SR FF with preference to the S input?
The part 1 and the part 2 are amazing videos. Very easy to understand and follow. I have noticed. The low-level switch is open when there is water, and the high-level switch is closed when there is water. Should not we use the normally closed switch for the low-level switch?
Hello, Thank you for your question! We see in network 1 both switches are shown logically “open” before any action happens. And in the simulator they are also open which simulates the physical position of the switch “normally open.” But when we close the switch on the simulator the logic of the “L_LeveL” switch turns “green” meaning we made it a logic “1” because we have no water in the tank and we just closed it. As it is stated when the level passed the level of the low level switch we open it in the simulator and it will not be fully “green” as you can see. But it looks “open” because we are just changing the logic. Therefore, with this logic we can’t not make it a normally closed switch unless we change the logic. Hope this clarifies your question. Happy learning!
Great video... But i have a small question.. When the liquid reaches to maximum level and high level switch is activated. And mixer and valve are turned on respectively. But when the liquid goes below high level switch the status of high level switch will change and that will affect the entire process... What say?
The high-level switch, when triggered at high level, starts the agitator and stops the pumps. But unlike the low-level switch, the high-level switch initiates a timer, which, after it times out, opens the bottom valve. The level will go below the high-level switch, but there is no logic that is activated when this happens. When the low-level switch is reached the cycle starts over again
Your tutorials are very impressive, am grateful to your impartation. Thanks. I am currently operating on 2# electric gas kilns and using plc board in operating to the system, so your program is helpful to me. Keep up with your good job.
Thanks a lot for the tutorial, I just have two questions: since the stop button is normally closed, doesn't it just reset the flip flops immediately? Also actuating the stop button seems to just discontinue power to the reset part of the flop, please explain how the stop button works. Thank you.
The stop button is a normally closed pushbutton in the field, so the PLC input is high (or "1") when the button is not pressed. In the video, the stop pushbutton bit had to be set before demonstrating the logic, indicated "not pressed". When the pushbutton is pressed, the contact is broken and the input goes low, or "0". This causes the NC contact to activate the "R" input to each flip-flop, which resets the "Q" output. The "S" input will then need to be reset and then set again to once again set the "Q" output.
Great tutorial. I know this is a small and relatively basic system, but how much more complex would a typical project be for a control systems engineer? This one had a few processes, and only a handful of I/o devices. I know modular plcs can have significantly more inputs and outputs. I have worked in an engineering environment for nearly a decade, and even in a relatively complex setting, I feel like the programming wouldn’t be difficult, but perhaps tedious.
Low level should be negated contact. Otherwise sensor will give out sigal while liquid is above low level sensor and will be resetting dischage valve flip flop. So if we set LowLVL contact as a NC it will close once level drops below bottom level thus setting on pumps. Of course a relay with NC contact can be used to invert LowLVL signal, but that's aditional cost.

Great to hear that!
animation videos are always helpful and easy to understand....thank you
I did a similar project for my plc’s I final in school. Our instructor had us se it up for full and half batches as well as mix 1 and mix 2.
The way you say the word “energize” reminds me of Star Trek 😃
Great content!
It helps a lot especially when your have basic plc training.
Very easy way to understand the basic lvl plc programming. Thnks a lot
You are very welcome!
Nice video , but ... With this kind STOP button , your reset is active until stop button is not pushed
Thank you very much for this video. I am an Electrical Engineer, machines and drives.
Amazing, Ala! Thanks for sharing.

I think there is a mistake in the last step of the program. The 'stop' button must be modeled as a normally open contact in the program, or if we want to model it as a normally close contact, we should put it in series with the contacts in 'reset' signal path.
Yes. I noticed this too. An open circuit is required to stop. Accordingly, at the input "R" of the trigger, this signal needs an inversion.
I am also agree with you
Thank you bro , you are a great teacher

The RS flip flop has the opposite priority of S and R as the SR flip flop.

I think law level switch(L-LEVEL) should be normal close , not as mention to be normal open , then we may need to make some change after.
