Hi friends, how are you doing? Today will integrate all of what we have learned so far in this series to build the first project based on ladder logic programming. Because we all are interested in industry, we pick one industrial project, Bottle Filling and Capping Projects, which is very common today. The problem we are going to solve today is bottle filling and capping. We have learned all basics of ladder logic including contacts and coils operation, logic gates, rising and falling edges, timers, and counters. So, today we will utilize all of these components to implement a complete ladder program of filling and capping problems.
For simplifying the operation of the process of filling and capping, fig. 1 shows the process flow which simply contains the main motor that drives the conveyor belt on which the bottles are running starting by hitting the start button. The conveyor belt starts running driven by motor M1 and the bottles move until sensor S2 detects one bottle, then motor M1 stops and the belt does so. At the same time, valve V1 opens to let water get dropped into the bottle until it reaches specific level thanks to level sensor S1. Then valve V1 closes and motor M1 goes on moving. Then when sensor S3 sees a bottle, the piston P1 is activated for capping the bottle and so on.
Fig. 1. The Filling and Capping Process
As you can see, for every single process in the industry, there are inputs and outputs. The inputs represent the sensors and user requests like starting and stopping the process. While the outputs are represented by actuators like motors, valves, and pistons. Table 1 lists the inputs and outputs of the filling and capping process. It shows the process consists of four inputs and three outputs including the function and description of each item.
Table 1: The list of Inputs and outputs of the Process
Before going to ladder programming, we should design the logic of the operation to build guidelines on which we can develop the ladder logic. According to the operation description we stated aforementioned above, we can express the logic in lines as follows:
As you see in these few lines, we just wrote the philosophy of the filling and capping process’s logic. And the process keeps repeating until user requests stop. So now let’s move to convert this written logic into ladder logic rungs and enjoy for sure simulating the process in our lab to verify the logic we designed is correct or we need to amend.
Before getting starting the filling and capping programming, we need to design the list of inputs and outputs of the program and their initial states. Table 2 shows a list of the inputs and outputs with their addresses and initial states.
Table 2: The Inputs and Outputs list with Addresses and Initial States
Figure 2 shows the first network in the designed ladder program. My friends, do not feel it a complicated because the fact is that, it is really simple. First of all, the start button to run the conveyor belt motor coil and latching is considered for letting the belt resumes running even after releasing the start button. Also, you should ask yourself during design two questions. The first is when the motor of the conveyor belt will be running and when to stop it? The answer to these two questions will end up with completing this network. For instance, the first question which inquiries about when to start the conveyor belt can show that the belt should be running by hitting the start push button to represent the request of the user to run the process. But, while the filling process is in progress marked by the activation of sensor S2, the conveyor should stop waiting for the filling process to complete by closing the valve when reaching the filling level limit noted by sensor S1. So, closing the valve is another signal that starts the conveyor once again. On the other hand, the conveyor belt should stop when the stop is requested by the operator in addition to sensor S2 that indicates a presence of a bottle in the filling station. So, you can notice two parallel branches to run the conveyor belt, one by start push button and one for latching. In addition, another parallel branch is added to run the belt by showing the completion of the filling process thanks to the signals of valve V1 status.
Fig. 2: Ladder Logic Network 1
Now, let’s have a look at the valve and ask ourselves the same question as what we have done with the motor of the conveyor belt (M1). what makes the valve V1 get closed and what causes it to open? For those causes to open the valve are the signal of sensor S1 that tells the bottle that is being filled is already filled and all set to move to cap station in addition to the latching consideration. So, we have two parallel branches, one branch for the sensor S1 and the other one from the valve status contact for latching. Those parrel branches connected in series to show “AND” logic with the sensor S2 to make sure of the presence of a bottle in the filling station. On the other hand, the stop push button represents an ending request received at any time from the user to close the valve.
Fig. 3: Ladder logic network 2
Now, the process goes on and the bottle has just left the filling station and has reached to capping station. That has been recognized thanks to sensor S3 that detects a bottle that has just arrived at the capping station. As a result, the piston should be activated. Firstly, a timer has been utilized to let the piston activated for some amount of time that is enough to let the capping process be comfortably completed. So, in-network 3 shown in fig. 4, a timer which is of off-delay type is utilized to activate the capping piston for plenty of time to let the capping process be completed as shown in fig. 5.
Fig. 4: Ladder Logic Network 3
Fig. 5: Ladder Logic Network 4
And finally, in-network 5 shown in fig.6, the falling edge signal of the piston denotes the completion of the capping process. So, a counter which is of type count-up timer is triggered to count up to determine the number of the processed bottle so far. The preset value has been set to a specific value i.e. 100 which can be used to perform maintenance or end a batch process for 100 bottles to be filled and capped.
Fig. 6: Ladder Logic Network 5
After translating the writing logic to a ladder program that is composed of a couple of rungs, the second compulsory step is to verify the syntax of the ladder program and make sure that the program is free of error. So, we show you in fig. 7 the compilation results to show there is no error with the written code so far. By doing this verification, we are all set now to upload the program to the controller and check the logic and operations.
Fig. 7: Compiling the Designed Ladder Logic Program
It is time to go to our lab and open the simulator to check the design and written ladder code. Figure 8 shows the initial state of the program before starting the process. It is clear that the conveyor belt is stopped and the status of all sensors, pushbuttons, actuators are as their aforementioned initial states.
Fig. 8: Initial State of the Inputs and Outputs Before Starting the Process
Now, let’s hit the start push button to start the process and watch what is going on. Figure 9 shows good news!!! By hitting the start button, the process correctly started and the motor M1 that drives the conveyor belt starts spinning. But, how about checking to release the start pushbutton by leaving our hand to see what’s going on?
Fig. 9: The status After Hitting Start the Process
WoW!!, well done, latching is working as shown in fig. 10 as the conveyor continues spinning even after releasing the start button thanks to applying the latching technique.
Fig. 10: Conveyor Still Running Even after Release start Push Button Thanks to Latching
Once a bottle is presented at the filling station, sensor S2 is activated. Consequently, the conveyor stops waiting for the filling process to complete. But, when does the filling process ended and how to know it’s done already to go further?
Fig. 11: Conveyor Stops when a Bottle Presents at S2 for Filling
Well! Sensor S1 is there to watch the level to which the liquid reaches in the bottle that is being filled. Once the limit is reached, sensor S1 is activated telling hey here we go, the filling process is over and now we ready to go further to the next step which is the capping station as shown in fig. 12.
Fig. 12: The Valve is Closed by reaching the Limit Level and S1 is ON
Because the valve is closed after the filling limit is reached, the conveyor continues spinning and sensor S2 is deactivated showing the bottle has been filled and left the filling station. However, the conveyor belt keeps running thanks to the latch again as shown in Fig. 12.
Fig. 13: The Conveyor belt Goes Running by Closing The Valve V1
Let’s now my friends check what’s happening by reaching the capping station? Astonishing !!! as we put there our agent to tell us a bottle has arrived for capping which is sensor S3, once that happened, sensor S3 is activated and hence activates the piston to retract and keep retracted for a sufficient amount of time to let the capping process be completed thanks to using a timer of type off-delay timer. So first fig. 14 shows in network number 3, the timer is activated and starts counting the time that is preset to 2 seconds and in the same time activates the piston to keep retracted during that time based on the nature of operation of an off-delay timer.
Fig. 14: The Piston is Activated by Reaching at Capping station When S3 is ON
And finally, the counter is utilized to count the processed bottles which are triggered by the falling edge of the piston denoting completion of a filling and capping process.
Fig. 15: The Counter Counts up Every item After the Capping Process
By reaching this line in our tutorial, I would like to congratulate you that you are now all set to think about complete basic problems in the industry and design the logic to solve them and write the ladder code. Is here the end station of our ladder logic tutorial? For sure no, we still have a lot to move forward from the basic level to become experts. So wait for the next tutorial in which we go deeply into details of math and logic functions and data processing.
In this step-by-step guide, we’ll look at all aspects of hiring Flutter app developers for your business, including interviewing, do’s and don’ts, and the pros and cons of using the Flutter UI.
Before you start the recruitment process, in order to hire Flutter developers for the first time, you need to carefully consider all the pros and cons. It’s always tempting to go straight to the latest technology and assume it’s the best way forward, but you never know what’s around the corner in the IT world. Before you commit to a new language or tech stack, you should think about your goals and the apps you would like to build in the future. Evaluate the pros and cons of Flutter before you dive in and hire a Flutter developer.
Flutter’s main benefit is its speed to market. You can build multiple apps across multiple platforms (like desktop, mobile, and web) at the same time, which cuts development and testing. Apps built on Flutter are extremely user-friendly and intuitive, allowing you to add fine details and attractive interfaces that give you a real branding edge over your competition. That doesn’t mean that there aren’t any disadvantages. Flutter is very new and still evolving. If you hire Flutter app developers, chances are they haven’t had the years of experience you may need to really realize the full potential of your project. If you can’t find a very experienced team, you either have to contend with developers learning on your dime, or you may have to opt for a more stable and mature platform.
You’ve made the decision to hire Flutter developer. Now you need to figure out where you are going to find them. You can either put out a vacancy on LinkedIn, Marketplace or conventional job boards or hire workers on a contract basis. Again, whichever approach you choose will come with its own advantages and disadvantages.
If you have the time, looking for Flutter developers yourself can be rewarding. You can spend some time on forums and blogs or sites like Quora and Reddit to build up relationships and curate referrals, or just put a vacancy up on a job board and wait for the applications to roll in. Unfortunately, this approach can take months to complete. You’ll have to find the candidates, interview them, and onboard them. You can use a formal recruitment agency, but that’s a very expensive option and really not feasible for a start-up.
Most companies end up using freelancers or offshore agencies. Sites like Upwork or Fiverr will put you in touch with developers right away. They may be a little pricier than hiring someone via an offshore agency, and they may not be available to you exclusively, so bear that in mind. On the other hand, they will have experience working with a variety of clients. That means that they’ve learned a lot of lessons and gained a lot of experience.
Offshore agencies are a great way of finding skilled developers. This involves engaging with a trusted agency in a country like Ukraine to find talented Flutter developers for your project. It’s much cheaper and faster than doing the hiring on your own.
Before even considering someone’s application, you have to know the technical skills required from a good Flutter developer. Look for candidates with solid knowledge of native programming languages, particularly for Android app development. This includes Java, C, C#, Lua, Kotlin, and others. You should also pay close attention to their seniority. Flutter is easy to learn, but you will need a few senior developers along with the juniors if you want to launch your app quickly. Candidates should understand and have a good working knowledge of Git, GoF patterns, SQL, and how the software development life cycle works.
Make sure that at least some of your developers have worked on apps similar to the one you’d like to build or within the industry that you are targeting. It’ll shorten the learning curve for everyone (and might lead to some key discoveries and innovations).
Once you’ve found your candidates, you should put them to the test. You can provide them with a few coding challenges and ask them questions about their experience and approach. Don’t just focus on their technical capabilities. It’s a good idea to ask about their style of working and personality, too. You want to make sure that your new hires can fit in with your existing team and company culture.
A few good questions to ask could include:
Once you’ve picked your top candidates, always make sure to double-check their references. It’s always a good idea to give their previous employers a call.
Large enterprises and Silicon Valley-based tech companies are all turning to Flutter these days. Finding good Flutter developers for hire isn’t easy, but it’s a surefire way to ensure that your apps are built quickly and effectively. Follow these simple steps, and you’ll soon have your own team assembled.
Plastic injection molding involves exposing plastic pellets to extreme temperatures to melt and become malleable. Afterward, manufacturers inject the melted plastic into a mold cavity so that upon cooling, the plastic adopts a specific shape producing the final product.
The versatility of the process makes plastic injection molding a highly beneficial method of producing plastic parts. It's similar to steel forging, finer grains are molded making the final product much stronger. If you decide to go for the plastic injection molding method of creating plastic parts, you will realize the reliability and simplicity that the technique provides. Here are some of the significant benefits of plastic injection molding to consider:
If you are looking for a way to produce plastic parts faster, plastic injection molding is your technique. This method of producing plastic parts offers high production output rates, making the process efficient and cost-effective. Many factors like the complexity and size of the mold will influence the speed at which you produce the final result.
However, cycle times remain tight, with the longest being two minutes, more than enough time to make more significant quantities of mold. Plastic injection molding is the best way to increase your profit margins. All you need to do is to leverage the short period between cycles that offer quick turn injection molding to produce more products for the market.
One of the things manufacturers seek when looking for a production method is handling complex part design and making precise replicas. The best way to ensure efficacy is to hire qualified designers to develop the right design that will maximize efficiency. Not all plans are immune to processing mistakes.
High-volume injection molding can help optimize efficiency in the process, but you will still need a good design that your machines can produce consistently. If you are a manufacturing manager, take time to learn about the fundamental design elements like wall thickness and rib design to ensure the injection process runs smoothly.
Before you begin the plastic injection molding process, you need to understand the flexibility and rigidity that the final product needs. Afterward, you can design a plastic part with appropriate integrating ribs or gussets that will offer the right strength to the final product.
Another essential factor in helping you determine how much strength and stability you need to incorporate into the plastic part is how the customer intends to use the product. It would be wise to carefully select suitable materials for your final product, especially considering its exposure to specific external environments.
One of the most incredible things about plastic injection molding is that manufacturers do not limit themselves to specific materials or colors. Although material and color are critical components influencing plastic parts creation, the possibilities are endless. If you want the best out of your injection molder, choose the one that can handle a wide variety of resin.
Some things to consider when choosing a plastic injection molder are water absorption, impact and tensile strength. Moreover, there are various coloring systems for plastics. Consider each coloring system's unique benefits, properties, and drawbacks before settling on one.
Manufacturers must comply with a company's green initiative. The production process should accommodate sustainability and safety while still preserving quality. It is not uncommon to generate excess plastic during the production process.
The wise thing to do would be to implement a circular economy model by finding another company, a recycling company, to help manage the excess plastic. Alternatively, manufacturing managers should have effective machinery to minimize waste.
Plastic injection molding offers high output rates. This advantage, coupled with the high-level production of plastic parts, contributes towards cost savings and effectiveness. Moreover, the entire process usually requires minimal supervision because molding equipment typically has automatic tools that ensure streamlined operations.
The final result of the plastic injection molding process is high-quality plastic parts that enhance customer satisfaction. The low labor costs enable manufacturers to enjoy high-profit margins.
If you are seeking a way to make high-quality plastic parts, purchase computerized and automated plastic injection machinery to enjoy the manufacturing advantages of this production method.
The usage of 3D printing has received a lot of attention, but what exactly is FDM 3D printing or FFF 3D printing? FDM 3D printing is used in a variety of sectors. Automobiles and a broad range of consumer products makers are among the industries. They use FDM to aid with product design, prototyping, and manufacturing. Some product companies employ FDM 3D printing since the thermoplastic utilized during creation is ideal for children's toys to sports gear.
FDM, as previously said, is among the most democratized 3D printing services, enabling hobbyists and amateurs to produce new goods quickly. They can quickly develop, iterate, revise, and print parts that meet their specifications.
The gifting business is also adopting 3D printing technology to make present products, riding the wave of customization. FDM 3D printing technology is ideal for gifting since it provides dimensionally correct, durable, and cost-effective options.
Furthermore, FDM 3D printed parts can be post-processed in various ways, allowing for the creation of visually pleasing goods.
It's a widespread misperception that FDM 3D printing can only be used to make gift items and prototypes. FDM is well-known for producing durable and valuable items that may be put in end-use applications.
Manufacturing 3D printers can generate end-user application components in aerospace, automobiles, production, and healthcare implementations.
FDM 3D printing innovation has aided many physicians worldwide in better planning surgeries by supplying them with organs that are an identical reproduction of the patient in question. They have a precise structure, may be made hollow or solid depending on the requirements, and can be printed in a matter of hours.
This has enhanced surgical preparation and quality, decreased surgery duration, and even helped patients have a more significant operation encounter.
This is one of the initial examples of FDM printing in action. It is well known that 3D printing was developed to produce prototypes fast, and as a result, 3D printing was dubbed Rapid Prototyping for a long time.
Because FDM printing can manufacture incredibly intricate items, it's an excellent alternative for companies that have to produce parts that must be fit and form checked.
As a result, prototyping remains one of the most common applications of FDM technology. FDM provides a simple, cost-effective, and rapid way to create prototypes.
Architectural prototypes of housing projects, power stations, arenas, and other structures were once created using various materials such as wood, polystyrene, acrylic, and other similar materials. In addition to the considerable production lead time, these were not only more expensive to produce but also more cumbersome to move.
Architectural models may now be quickly manufactured, carried in parts, and assembled on-site thanks to the advent of FDM 3D printing technology. They also have a strong resemblance to the original design.
Because of its ease of use and low cost, this additive manufacturing process is quite prevalent among businesses. Fused deposit modeling is a lifesaver for beginners, aspiring engineers, and bootstrapped firm owners.
Figuring out what to do can become even more overwhelming when you start asking whether you need a custom-made solution or you can purchase one off the shelf, if you need to simply upgrade a system or if an entire overhaul is necessary, and how much can be done in-house. You can find yourself lost in the details before you have even had a chance to really examine the big picture. However, the good news is that there is still a process you can follow even when the situation is a complex one. Consider the points below as you move forward.
Do you know what your problem is? Before you say yes, think carefully. It is not uncommon to confuse symptoms with the cause. It may be worthwhile to talk to others within your organization to make sure that you are correctly identifying the issue. If the issue is one that affects your customers, you may want to get some feedback from them. When choosing the right tech solution for your business, it's also worth considering how traditional marketing tools like a dental direct mailer can seamlessly integrate with digital systems to enhance patient outreach and retention.
You might be struggling with meeting compliance standards when it comes to dealing with refrigerated assets. You might assume that the issue is with some of your staff or with how these assets are handled. This could cause you to overlook the fact that reliable refrigeration monitoring systems are what you need. Reefer monitoring solutions are cost-effective, but you might need to dig to the root of your problem to identify them as the answer. Of course, there are a few additional steps you should also go through from examining the impact on employees to choosing the tech solution.
If your employees are affected by the change you're making and they are resistant to that change, you need to figure out why. It could be because there is something that you are unaware of in their processes that will be negatively affected. It might be because they have higher priority issues that they want you to address or because they have a different perspective on what the solution should be, which is one reason why you should seek feedback widely in the planning stages.
On the other hand, if the change is necessary, you will need to get them on board. This can be tricky because while there may be an overall advantage to the company, their own processes might become more cumbersome in certain ways. You will need to find a way to present the change to them that shows how it can benefit them as well. There is also simply the issue of resistance to change that many people have. In this case, they will eventually adjust, but you may need to provide incentives or find another way to balance the inconvenience of a potentially frustrating learning curve. Letting them be part of the discussion and the process can also help prevent the feeling that a top-down decision is being imposed on them.
Your solution needs to be in alignment with your organization's strategic plan over the next few years and your goals. How does it complement the priorities you have set? This can also help you decide whether the problem is something that needs to be addressed immediately or if there are other issues you should be focusing on more instead.
Sometimes, as in the case of compliance issues around refrigerated assets mentioned above, the issue is not one that can be shelved for a later date, but often teams and individuals can find themselves distracted by shiny new tech that can certainly deliver but which may not aid you in meeting your most important benchmarks in the years ahead. Taking all of this into account can also help you narrow down which solution might be the best since some may be better at aligning with your medium-term aims than others.
Planning can help you avoid some of the pitfalls described above. Is it true in other areas of life, like preventing your car from theft and putting identification on your pets’ tags in case they run off, planning does not prevent problems, but it can make them more manageable. There should be two aspects to this plan for finding tech solutions for your business.
First, if you develop a kind of blueprint for implementation, you can see how the tech fits into the overall operation, including existing systems and processes. Like a good business plan, this can also highlight gaps in your thinking and anything else you may have overlooked. The other aspect of the plan is articulating criteria that will tell you whether the solution was the right one. This criterion should be as specific and measurable as possible in the same way that a goal should be. In fact, once you have established it, you can use it to work backward and see if what you have chosen is likely to deliver the necessary results.
When you start to look at the actual tech, there are a number of things you should consider before you make your decision. To start with, look for something that is scalable so that it can grow with your business. You should also look for an effective user interface. Look at how adaptable and customizable it is. Consider as well what kind of balance you want between accessibility and security. It may be important that employees can access a platform from anywhere.
However, you also need to make sure that any important data is protected. Be sure that you consider how much training will be necessary. Even if your employees are enthusiastic about the new tech, if learning how to use it is going to be very costly in terms of time and money, you may want to consider another option. Another thing to look at is how much support you will get with the transition, installation, updates and any troubleshooting. In all of these areas, see what experiences others report as well. You may not be an early adopter, but the advantage of this is that you can be more certain that the tech you have chosen is stable and reliable.

That’s All today. I hope you can understand the difference between examples and applications. Keep tuned and thanks for reading our tutorial.
There are two edge types:
Figure 3 shows the general symbol of a rising edge. The letter “P” denotes a positive edge. while fig. 4. Depicts the rising edge in ladder logic in the TIA portal of siemens software.
In ladder programming, the rising edge shows a positive rising edge received for the signals. In fig. 4, the rising edge is for the signal tagged as “TagIn_4” and the previously saved value is stored in “Tag_M”. the system can recognize a rising edge by comparing the buffered value stored in “Tag_M” and the current value in “TagIn_4”. For example, if the previous value stored in “Tag_M” is False, and the current value in “TagIn_4” shows high logic, this would mean a rising edge is received.
Figure 5 shows the general symbol of a falling edge. The letter “N” denotes a negative edge. while fig. 6. Depicts the falling edge in ladder logic in the TIA portal of siemens software.
In ladder programming, the rising edge shows a negative or falling edge received for the signals. In fig. 6, the falling edge is for the signal tagged as “TagIn_4” and the previously saved value is stored in “Tag_M”. the system can recognize a falling edge by comparing the buffered value stored in “Tag_M” and the current value in “TagIn_4”. For example, if the previous value stored in “Tag_M” is True, and the current value in “TagIn_4” shows low or false logic, this would mean a falling edge is received.
Now let’s do the same concept on the output side, fig. 7 shows the set output ladder instruction on a rising or positive edge. In this instruction, the result of the logic operation (RLO) which represents the left part before the output is evaluated to check the transition in its state. If the RLO changes from false to true then the output will be set for one scan cycle.
Figure 8 shows an example of the set output on a positive edge. On the most left, the coil with the letter “P” inside represents the instruction. The instruction works by saving the previous value of RLO into “Tag_M” and verifying the changes in a state with “TagOut”. For example, if the “Tag_M” holds a true state while the previously stored value in “Tag_M” was false. That would show a positive edge and the output will be set to true for the complete scan cycle.
Figure 9 shows the set output ladder instruction on a falling or negative edge. In this instruction, the result of the logic operation (RLO) which represents the left part before the output is evaluated to check the transition in its state. If the RLO changes from true to false then the output will be set for one scan cycle based on detecting a falling edge of RLO.
Figure 10 shows an example of the set output on a falling or negative edge. On the most left, the coil with the letter “N” inside represents the instruction. The instruction works by saving the previous value of RLO into “Tag_M” and verifying the changes in a state with “TagOut”. For example, if the “Tag_M” holds a false state while the previously stored value in “Tag_M” was true. That would show a negative or falling edge of the RLO. Consequently, the output will be set to true for the complete scan cycle.
Now let’s go to our lab and open a simulator to enjoy practicing very critical points in ladder logic programming. Yes, my friends, these are very critical points and are used smartly in solving very hard problems to solve. But, by comprehensive these points, you will be superb in your field as a prospective ladder logic programmer. Two points we are going to simulate, the first one is the ringing and falling edge of the inputs and their effects on activating and energizing the output for a complete pulse. And the rising and falling edge cases of the result of logic output (RLO) and its effects on energizing the output for a complete pulse.
Now, let’s assume we have a situation in the factory that, when specific action occurred, the output will be energized. In the example represented by fig. 11, when and only when input A, turned on, we need to start the output. That means the only scenario in which the output is turned on is when input A state changed from false to true. So let us simulate three scenarios, the first one shown in fig. 11, in this scenario the input previous status is saved in input B, while the current or new state is saved in input A. notice when the input does not change and it is false, the output is turned off.
Now let’s turn on input A, so now input changed from false to true as shown in Fig. 12. Ohh, notice the output comes true and that’s the rising edge at when the input changes from false to true.
And in the last scenario, when the input keeps true meaning the previous status was true and the current state is true, then the output is false as shown in Fig. 13.
In a conclusion, in rising edge, the output only gets true when the input changed from false to true.
Now, let’s assume we have another situation in the factory that, when an input or sensor turns off or changed from true to false, the output will be energized. In the example represented by fig. 14, when and only when input A, turned out from ON to off, the output will be energized. That means the only scenario in which the output is turned on is when input A state changed from true to false. So let us simulate three scenarios, the first one shown in fig. 14, in this scenario the input previous status is saved in input B, while the current or new state is saved in input A. notice when the input does not change and it is false, the output is turned off.
Now let’s turn on input A, so now input changed from false to true as shown in Fig. 15. Ohh, notice the output is false because that’s not a falling edge as the input changes from false to true.
And in the last scenario, when the input changed from true to false which is a falling edge. Therefore, the output turned on as in fig. 16.
In a conclusion, in a falling edge, the output only gets true when the input changed from true to false.
Now, my friends, we need to run the output for one pulse based on the result of logic output (RLO). Figure 17 shows the scenario of having a false state of the RLO, the output is false because there is no falling edge detected for the RLO.
Figure 18 shows the case when the RLO is turned from false to true, the output comes true but for one pulse notice the previous status represented by buffer has become false but the output after pulse time returns to false. However, the pulse of the output has been detected thanks to energizing output tag_5.
Figure 19 shows the very initial case of set output with a falling edge. To show, the case of the falling edge of RLO, we use another rung that would energize another output at Q0.6 when and only when the falling edge of the RLO occurs. In Fig. 19, the RLO was false. Therefore, there is no cause for a falling edge when RLO changed from true to false. So the output shows a false state.
Now let’s turn on the RLO, so the RLO changed from false to true which is still not a case of a falling edge of the RLO. SO the output is still false as shown in Fig. 20 represented by output Q0.6.
Figure .21 shows the scenario of the RLO turning from true to false which is a falling edge. In that case, the output will be turned on for one pulse and as a result, latching output at Q0.6 as shown in rung 2 of fig. 21.
Once more I would like to thank all my friends for continuing with our learning and practicing our PLC ladder logic series. Now we have learned the concept of edge detection, its importance, and how we can utilize the rising and following edge in some critical and accurate cases of logic. The rising and falling edge of the inputs can energize an output in a pulsative way or for only one pulse. This scenario exists in the industry and is very common. For example, when you want to energize a safety device by the occurrence of some conditions like increase of liquid level or temperature or pressure et cetera. Also, the result of logic output (RLO), can be used to set or reset output for one pulse. In the next tutorial, we are going to introduce the latching in more detail showing why we need to latch an output, the ways of latching with examples, and for sure enjoying our practicing with the PLC ladder logic simulator.
Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sensor works:
| Where To Buy? | ||||
|---|---|---|---|---|
| No. | Components | Distributor | Link To Buy | |
| 1 | ESP32 | Amazon | Buy Now | |
Capacitance is determined by the geometry of the conductors and the dielectric materials used. Changing any of these factors will result in changing the capacitance.
C = Ad
As we know, the human body also carries a small electric charge. So, when a body approaches the metallic plates(of a capacitor), the mutual capacitance between the two metal plates decreases. This change in capacitance is used to detect the touch in these capacitive sensors.
So, if someone touches any of these pins, ESP32 can easily detect it. The pin mapping of touch-sensitive pins in DOIT ESP32 DevKit V1 with GPIO pins is shown below:
| ESP32 Capacitive Touch Pins | ||||
|---|---|---|---|---|
| No. | Parameter Name | Parameter Value | ||

We are using the Arduino IDE development environment for programming ESP32. If you are new to Arduino IDE, read out How to Install ESP32 in Arduino IDE. Let's use the builtin Touch Sensor example in Arduino IDE:
In Arduino IDE there are two example codes available for the ESP32 touch sensor. We will discuss and implement both example codes in this tutorial. So, let's first open the TouchRead Code:
Here's the code for the TouchRead Example:
// ESP32 Touch Test
void setup()
{
Serial.begin(115200);
delay(1000); // give me time to bring up serial monitor
Serial.println("ESP32 Touch Test");
}
void loop()
{
Serial.println(touchRead(T0)); // get value using T0
delay(1000);
}Inside the setup() function, the serial monitor is initialized at a baud rate of 115200 to display the sensor readings. Finally, we printed the message(ESP32 Touch Test) on the Serial Monitor:
void setup()
{
Serial.begin(115200);
delay(1000); // give me time to bring up serial monitor
Serial.println("ESP32 Touch Test");
}void loop()
{
Serial.println(touchRead(T0)); // get value using T0
delay(1000);
}These capacitive touch sensor pins are mainly used to generate an external interrupt for waking up ESP32 from low power modes(deep sleep mode). Moreover, can also be used to control external peripherals like LED blinking or tuning on a DC motor, when a capacitive touch-interrupt is observed. So, let's have a look at How to Generate external interrupt by touching the ESP32 capacitive touch pins:
Here's the ESP32 Touch Interrupt Code:
const int CAPACITIVE_TOUCH_INPUT_PIN = T0; // GPIO pin 4
const int LED_OUTPUT_PIN = LED_BUILTIN;
const int TOUCH_THRESHOLD = 40; // turn on light if touchRead value < this threshold
volatile boolean _touchDetected = false;
void setup()
{
Serial.begin(115200);
pinMode(LED_OUTPUT_PIN, OUTPUT);
pinMode(LED_OUTPUT_PIN, LOW);
touchAttachInterrupt(CAPACITIVE_TOUCH_INPUT_PIN, touchDetected, TOUCH_THRESHOLD);
}
void touchDetected()
{
_touchDetected = true;
}
void loop()
{
if(_touchDetected)
{
Serial.println("Touch detected.");
_touchDetected = false;
Serial.println("blink the LED");
digitalWrite(LED_OUTPUT_PIN, HIGH);
delay(1000);
digitalWrite(LED_OUTPUT_PIN, LOW);
delay(1000);
}
}Let's understand the code by parts:
const int CAPACITIVE_TOUCH_INPUT_PIN = T0; // GPIO pin 4
const int LED_OUTPUT_PIN = LED_BUILTIN;
const int TOUCH_THRESHOLD = 40; // turn on light if touchRead value < this threshold
volatile boolean _touchDetected = false;void setup()
{
Serial.begin(115200);
pinMode(LED_OUTPUT_PIN, OUTPUT);
pinMode(LED_OUTPUT_PIN, LOW);
touchAttachInterrupt(CAPACITIVE_TOUCH_INPUT_PIN, touchDetected, TOUCH_THRESHOLD);
}void touchDetected()
{
_touchDetected = true;
}void loop()
{
if(_touchDetected)
{
Serial.println("Touch detected.");
_touchDetected = false;
Serial.println("blink the LED");
digitalWrite(LED_OUTPUT_PIN, HIGH);
delay(1000);
digitalWrite(LED_OUTPUT_PIN, LOW);
delay(1000);
}
}This concludes the tutorial; I hope you found this helpful and also hope to see you again with a new tutorial on ESP32.
