#Automatedo #proximitysensor #capacitivePLC Communication Module #ShortsAutomatedo2024-09-14 | 🎥 Mastering PLC Communication Module for Industry Success 🤖✨
Communication modules are essential in industrial automation systems, providing extra communication ports or protocols when needed. In this short video, you will learn how these modules enhance your PLC system by enabling communication between devices like HMIs and VFDs, even when different networks (like Profinet and Profibus) are involved.
Learn how communication modules provide additional ports for seamless data exchange between devices, making your automation systems more flexible and capable. Watch now to get a quick understanding!
- The last, but by no means the least, is the communication modules. Communication modules supply extra communication ports or protocols that an industrial system may need.
- Usually, the CPU contains communication ports such as Profinet to connect with other field devices like HMIs over an Ethernet network.
- What if this PLC system wants to exchange data with a VFD via the Profibus network?
- Since the CPU only has Profinet ports, we need the help of a communication module that has a Profibus port on it. This port provides a cable connection to have exchanging data between the PLC system and the VFD.
- So, we can say communication modules provide additional ports on top of the ports we currently have on the CPU.
#Automatedo #plc #plctutorialWhy Standard PLC IO Modules Fall Short in Motion Control Applications #ShortsAutomatedo2024-09-07 | 🎥 Understanding the Need for Function Modules in Motion Control Applications 🤖✨
In this video, you will learn why connecting motion control applications, like speed sensors, to standard PLC IO modules compromises accuracy and speed. Discover why function modules are essential for precision in high-demand systems
- The question that may arise here is why don't we connect our motion control application to standard input/output modules?
- The answer is in these types of applications, speed, and accuracy are a must, so if we connect our motion control application, like the speed sensor here, to a regular input module, this module cannot provide the accurate and precise data needed for this application.
- Function modules or FMs are another part of PLC hardware use in motion control applications with high accuracy.
- Whenever the input/output signals consist of high-frequency pulses, the function modules are needed to handle high-speed counting.
- An interesting point about function modules is they work independent of the CPU. What does this mean? You may ask.
- It means regardless of tracking and providing input/output signals, the function modules process the data as well, which results in taking the load off the CPU.
- This way, the CPU can process and handle the remaining signals much faster.
In this video, you dive into the fascinating world of PLC hardware and explore the crucial role of I/O modules. 🚀

Learn how these modules bridge the gap between PLCs and the real world, making automation seamless and efficient! 🌐
- The next component of PLC hardware that we discuss is I/O or input/output modules that connect to different types of field devices.
- Based on signals used within the process, we can divide I/O modules into two categories: digital input and output modules, and analog input and output modules. How so? You may ask
- In industry, there are two kinds of signals used extensively: digital signals and analog signals. Digital signals are either off or on, while analog signals have a range of values.
- Digital input and output modules respectively receive and transmit digital signals, and they connect to the field devices that only have two statuses. These devices are either completely off or completely on.
- On the other hand, analog input and output modules deal with analog signals. These modules wire to the field devices that can measure or produce a variable signal that lies between a specific range of values

We'll break it down for you in this video.
By watching this video, you’ll get the answer to the following question: - What is the PLC CPU module?
- The CPU is the most important module among all PLC hardware components, that’s why we call it the brain of the PLC system.
- The CPU controls and monitors all PLC system operations, especially executing the PLC program based on the status of input field devices so, it can decide what output field devices should do.
- If the CPU stops working for any reason and cannot process the program, the whole industrial system will shut down.
#Automatedo #plc #plctutorialNPN Sensor Explained | Working, Wiring, and TestingAutomatedo2023-08-06 | 🎥 When dealing with 24-Volt DC sensors, it is common to encounter the term NPN, which can be challenging to understand as it is frequently used in the industry.
By watching this video, you’ll get the answer to these questions: - What is an NPN sensor? - How to test an NPN sensor? - How to wire an NPN sensor? - What is an NPN output sensor? - How does an NPN sensor work? - What is an NPN sensor used for? - How to connect an NPN sensor to a PLC? - What are the components of an NPN sensor? - What are some typical applications of NPN sensors?
NPN Circuit - The first step is to check if the circuit is designed to accommodate NPN sensors
- The NPN is shorthand for negative-positive-negative. The middle letter P in NPN stands for Positive polarity and serves as a reminder of a direct connection of the load to the Positive side of the power supply.
NPN Sensor Diagram - The internal circuitry of a 3-wire NPN sensor typically contains two main components: the sensing element circuit and an NPN transistor.
NPN Sensor Wiring - Active solid-state 3-Wire NPN sensors typically require an operating power to function.
- The power wire, identified by its brown color, is connected to the positive side of the power supply, while the blue wire is attached to the power supply's negative terminal.
- The signal output wire of the sensor, which connects to the input terminal of the load, is identified by its black color. This wire is the third wire of the sensor.
NPN Sensor Working - When the 3-wire NPN sensor doesn't sense any metal object, the active line goes low, causing the NPN transistor to switch off and function somewhat as an open switch. So, it leaves the NPN output circuit open, resulting in no current flowing through it and the alarm device remaining off.
- The sensor's detection of a metal object causes the active line to go high, then turns on the NPN transistor to act like a closed switch and activate the alarm device.
- Since the NPN sensor can be considered as receiving input power from the load for sinking it to the ground, it is commonly referred to as a sinking sensor.
NPN Sensor Connection to PLC - It is crucial to select a field sensor type that is complementary or opposite to the type of PLC discrete input module used to have reliable performance. Since the NPN or sinking sensor has been incorporated into this circuit, it is imperative to use a sourcing PLC discrete input module to match it.
- Finalizing the circuit requires attaching the sensor output, represented by the black wire, to the input of the PLC module and then linking the common terminal of the PLC module to the power supply's positive terminal.
Checking NPN Sensor - Lastly, you will discover how to test the NPN sensor to ensure it operates correctly. To do so, make sure you have a multimeter on hand.
- Attach the multimeter's red lead to the NPN sensor's black wire and connect the black lead of the multimeter to the ground.
- If the NPN sensor doesn't detect a metal object, then you can expect that the sensor's output voltage will be high, which indicates that it is supplying a voltage nearly equivalent to the power supply to the input of the PLC module.
- And you expect when a metal object enters the detection range of the sensor, the sensor's output voltage will be pulled down to almost zero volts.
#Automatedo #npn #sensorWhat is PNP Sensor? Working, Wiring and TestingAutomatedo2023-07-02 | 🎥 In the realm of 24-Volt DC sensors, it is inevitable to come across the term PNP, as it is a common and often confusing term used in the industry.
By watching this video, you’ll get the answer to these questions: - What is a PNP sensor? - How to test a PNP sensor? - How to wire a PNP sensor? - What is a PNP output sensor? - How does a PNP sensor work? - What is a PNP sensor used for? - How to connect a PNP sensor to a PLC? - What are the components of a PNP sensor? - What are some common applications of PNP sensors?
PNP Circuit - First, you should learn whether the circuit is designed for PNP sensors.
- The PNP is shorthand for positive-negative-positive. The letter N in the middle of PNP, short for Negative polarity, reminds you that the load should be connected directly to the Negative side of the power supply.
PNP Sensor Diagram - Let's take a closer look at the internal circuit design of a 3-wire PNP sensor. Generally, it consists of a sensing element circuitry and a PNP transistor.
PNP Sensor Wiring - Solid-state 3-Wire PNP sensors are classified as active devices and typically need a small amount of operating power.
- The brown wire of the PNP sensor, known as the power wire, is attached to the positive side of the power supply, and then the blue wire of the PNP sensor is connected to the power supply's negative terminal.
- The third wire of the PNP sensor, which is black, is identified as the signal output wire of the sensor that is going to connect to the input terminal of the load.
PNP Sensor Working - Whenever the PNP sensor doesn't detect any metal object, the active line is low. Thus, the PNP transistor is off and behaves somewhat as an open switch. As a result, no current flows in or out of the PNP output, and the light bulb is off.
- But detecting a metal object by the PNP sensor makes the active line goes high and subsequently turns the PNP transistor on to act somewhat as a closed switch. As a result, it enables the flow of current from the power supply's positive terminal, through the PNP transistor, towards the PNP sensor output and eventually to the negative terminal of the power supply via the load.
- So, the function of the PNP sensor in providing power to the load is why it is commonly known as the sourcing sensor.
PNP Sensor Connection to PLC - The type of field sensor used in the industry must be complementary to the PLC discrete input module type. Since you put the PNP or sourcing sensor here, you need a sinking PLC discrete input module to go along with it.
- Connect the black wire of the PNP sensor, which represents the PNP sensor output, to the input of the PLC module, and the power supply's negative terminal should be connected to the PLC module's common terminal.
Checking PNP Sensor - Finally, let's learn how to test the PNP sensor to see if it works correctly. To do so, you need to get your multimeter into play.
- Connect the red lead of the multimeter to the black wire of the PNP sensor and attach the multimeter's black lead to the ground.
- You expect if the PNP sensor does not sense the presence of a metal object, the PNP sensor's output voltage will be low, meaning the PNP sensor supplies almost zero volts to the input of the PLC module.
- And you expect if a metal object enters the PNP sensor detection range, the output voltage of the PNP sensor will be pulled up to almost nearly the same voltage of the power supply.
#Automatedo #pnp #sensorWhat is RTU? | Remote Terminal UnitAutomatedo2023-05-28 | 🎥 If you are searching for a solution to keep track of remote measuring stations, the Remote Terminal Unit or RTU is your best choice. The RTU is sometimes referred to by other terms such as Remote Telemetry Unit or Remote Telecontrol Unit.

Where RTU is used - Where most of the time, nobody is out there, there is no connection to the electricity grid, and no wired connection can be established
RTU Meaning - An RTU is a rugged standalone microprocessor-based electronic control device deployed in an industrial environment at specific locations, which informs plant operators about what's going on out there all the time.
RTU Function - The RTU acts as a local connection point to gather measured data from connected sensors. The RTU performs data processing on the aggregated data, and as a result, the received raw data is scaled and translated into a transmittable format. One way to achieve converted data from RTU is through the web interface via a PC.
RTU Communication with SCADA - When the number of RTUs increases, it is preferable to have a central master station. Here, RTUs establish interfaces between field instruments in physical processes and the automation control system.
RTU Hardware - The main components of an RTU include the power source, central processing unit (or CPU), discrete inputs, analog inputs, control relay outputs, and communication interface, which can be a port or an external antenna.
Differences between RTU and PLC - Although RTUs and PLCs share many common characteristics, there are some dividing lines.

RTD Sensor Working Principle - An RTD is a passive sensing device that uses a resistive element whose resistance is associated with the function of the temperature.
RTD Sensing Elements - Various metals are used to manufacture the RTD element. Typically, platinum is more often used.
Major Components of an RTD Sensor - The sensing element is the temperature-sensing component found at the end tip of the temperature sensor to which the process temperature is applied.
- Next, it consists of lead wires that attach the sensing element to the read-out devices.
- Next, we want to discuss the sensor sheath, which houses most of the temperature sensor's components to shield them from the surroundings.
- It is advised to have a thermowell when integrating the RTD sensor into an application.
RTD Sensor Types - Depending on the construction of the temperature sensing element, RTDs are divided into three basic types, which are the wire-wound, thin-film, and coiled element.
RTD Sensor Connection to PLC - Proportional to the temperature range, the temperature transmitter takes the change in resistance of the RTD element, changes it into a voltage, and converts the measured voltage into a four to twenty-milliamp analog signal.
#Automatedo #rtd #temperaturesensorOverload Relay Trip Class | Types of Overload RelayAutomatedo2023-03-26 | 🎥 If you want to know how overload relays trip and how long it takes for overload relays to trip under an overload condition, watch this video until the end.
By watching this video, you’ll get the answer to these questions: - What are two types of overload relays? - How does a dashpot overload relay work? - What is the trip class in the overload relay? - How does a bimetallic overload relay work? - How does a melting alloy overload relay work? - What are two types of thermal overload relays? - What are two types of magnetic overload relays? - How does an electronic (solid-state) overload relay work? - How long would it take for an overload relay to trip under an overload condition?
Overload Relay Explained - An overload relay is a sensory safety instrument that protects an electrical motor from a continual high current draw, preventing it from overheating. When the overload relay senses an overload condition that has persisted for a while, it will trip and notify a contactor of the problem, so the contactor interrupts the current flow and shuts off the motor.
Overload Relay Types - There are two different kinds of overload relays: thermal overload relays and magnetic overload relays. Two types of thermal overload relays exist, bimetallic and melting alloy. And the two main types of magnetic overload relays are dashpot and electronic.
Bimetallic Thermal Overload Relay - When an abnormally high current flows through the heating element, the bimetallic strip receives the heat produced by the heating element. As a result, the strip bends and causes the insulated rod and lever to be pushed to activate the tripping mechanism, which opens the normally closed contact, interrupts electricity to the contactor coil, and opens the power contacts to stop the motor.
Melting Alloy Thermal Overload Relay - When an overload condition happens, excessive current flows through, causing the heater coil to heat up sufficiently to melt the inner eutectic alloy. So, it enables the inner ratchet shaft to spin and releases the pawl, causing the spring-loaded contact to open, thus de-energizing the contactor coil and opening the power contact to stop the motor.
Dashpot Magnetic Overload Relay - Once the tripping current passes through the coils in the event of overloading, the magnetic field becomes more powerful, causing the plunger and piston to start moving upward against the displacement of viscose oil through the orifice. Due to the completion of upward movement of the plunger and piston, the normally open contact closes in the trip circuit and de-energizes the contactor coil, thus opening the power contact to turn off the motor.
Electronic Magnetic Overload Relay - When continual overloading occurs, the created current flowing through the CT wire increases, which is then processed by the circuit board. After the internal circuitry finds out that the motor is pulling a high current, it will send a command to open the auxiliary normally closed contact, thus interrupting the power to the contactor coil and deactivating the power contacts to stop the motor.
Overload Relay Trip Class - Each manufacturer should provide a graph displaying tripping time as a function of current. On a logarithmic scale, this graph shows tripping time on the y-axis and illustrates current as a multiple of the overload current on the x-axis.
- The trip class describes how long it takes for an overload relay to trip while carrying a current equivalent to six times its existing setting.
#Automatedo #relay #overloadWhat is an Overload Relay? Connection & Working PrincipleAutomatedo2023-02-26 | 🎥 If you are curious to know what an overload relay is, what an overload relay consists of, how an overload relay is coupled into a contactor to protect a motor, what differences it has with a circuit breaker, and how to test an overload relay to check if it is functioning, watch this video until the end.
By watching this video, you’ll get the answer to these questions: - What is a motor starter? - What is motor overload? - What is an overload relay? - How to test an overload relay? - How to wire an overload relay? - What causes overload current? - How does an overload relay work? - What are the components of an overload relay? - How to connect an overload relay to a contactor? - What is the difference between a circuit breaker and an overload relay?
What is Motor Overload - If a motor draws too much current and generates too much heat, it indicates running in overload. So, to protect products in industrial automation, an overload relay is used to attach to a contactor to prevent motors from operating in overload.
Overload Relay Operation - Once the overload relay detects an ongoing overload condition for a considerable time, it will trip and send feedback to the contactor, so the contactor breaks up the current flow and stops the motor.
Motor Overload Causes - When a rotor gets jammed, and there is a mechanical obstruction. - When the process of aligning shafts with each other is not properly executed. - When the ambient temperature is high, and there is inadequate ventilation. - When a motor is undersized to handle a load which causes additional stress on a motor, and - When bearings, responsible for supporting the shaft inside a motor, have been damaged.
Parts of an Overload Relay - Adjustable current setting: By using this dial, you can specify the amount of current the motor must draw to be considered overloaded. In other words, the motor's rated FLA or Full Load Amps can be set here.
- Built-in auxiliary contacts: A pair numbered 95 to 96 is normally closed, whereas a pair numbered 97 to 98 is normally open.
- Reset button: This design allows you to toggle between manual and automatic reset modes and functions as the reset button.
- Test trip button: It may be utilized to simulate a trip off the overload relay to check if the overload relay is working correctly.
- Trip indicator: provides the status of the overload relay visually. Meaning, when an overload condition happens, this indicator turns on.
Difference between Overload Relay and Circuit Breaker - Using a circuit breaker, you can protect a motor from sudden high-current events caused by a short circuit.
- On the other side, an overload relay protects a motor from the excessive current being drawn from the supply.
Overload Relay and Contactor Connection An overload relay cannot be used to operate a motor on its own, so you need to pair it with a contactor. Typically, an overload relay is positioned beneath a contactor, often having three prongs extend outside its housing coupled into the contactor load side terminals.
Overload Relay Testing Procedure Finally, we will show how to test the overload relay using a multimeter set to the Continuity Beeper.

- In this 4-wire current loop we have a power supply, a 4-20mA angular transmitter, and a receiving device such as a PLC analog input module.
- By bringing the power supply voltage to this 4-wire angular transmitter, we turn it on and make it operational. From here, the connection is pretty straightforward.
- The positive polarity of the transmitter milliamp signal connects to the positive polarity of the PLC analog input. Also, the negative side of the transmitter goes to the negative side of the PLC analog input.
- Through these separate cable cores, the transmitter brings the 4-20 milliamp signal right over to the PLC analog input with a return path.
#Automatedo #transmitter #wiringWhat is HMI? | Human Machine InterfaceAutomatedo2023-01-29 | 🎥 An HMI or Human Machine Interface is simply a control unit that facilitates the integration of operators into complicated industrial processes by delivering a user-friendly dashboard.
By watching this video, you’ll get the answer to these questions: - What is HMI? - Why is HMI used? - Where is HMI used? - What is HMI design? - How does HMI work? - What is HMI software? - What is HMI Hardware? - What is the HMI function? - What does HMI stand for? - What are the types of HMI? - What is HMI programming? - What is the purpose of HMI? - What are the advantages of HMI? - How does HMI communicate with a PLC?
HMI Explained - Because PLC is just hardware, it cannot display signal values instantly to operators unless technical staff with a personal computer and necessary software establish a connection to the PLC and check the program status online to keep an eye on signal values.
- It is not a practical method for operations employees to regularly check what the PLC is doing, and that’s where a human-machine interface, or HMI for short, comes into play.
HMI Types - A variety of HMIs is available in an industrial setting, such as touchscreen, screen with buttons, built-in screen, handheld screen, computer screen, and mobile screen
HMI Hardware - The hardware layouts of most actual HMIs are similar, which include the following: screen for monitoring, control panel, and communication port
HMI Software - The software configurations of most genuine HMIs are alike, which applies in two steps.
- First, development. A personal computer is used to program the HMI through special software. And the Second step that applies in the HMI software configuration is runtime.
HMI Design - If you are interested in HMI programming, you should consider some essential design tips, such as user awareness, visibility, simplicity, and consistency
HMI to PLC communication - For the HMI to provide an interface for a manufacturing line, the HMI usually needs to be connected to a programmable logic controller or PLC.
- Compatibility between the HMI and PLC is required, meaning they must be able to communicate with one another.
HMI Operation: - The PLC will receive information from sensors and will start processing the collected data into logical combinations.
- As soon as the PLC provides real-time data directly to the HMI, the HMI is used to convert complicated process variables into information in the form of a graphical way.
- At this point, the operator can send commands through the HMI screen, and the HMI will transfer user inputs to the PLC to be processed into the logical format.
- Then the PLC sends translated data to the actuators to be executed over a given industrial process system.
HMI Function - Most HMIs have the same basic and extensively utilized functionality, such as monitoring, controlling, alarms management, data logging, and troubleshooting
HMI Advantages: - And finally, let us talk about the benefits of implementing HMIs, including increased visibility, enhanced efficiency, decreased downtime, ensure safety, ease-of-use, and cost reduction.
#Automatedo #hmi #hmiprogrammingPLC Power Supply #ShortsAutomatedo2023-01-11 | 🎥 As a PLC expert, you should have a basic understanding of the physical components that make up a PLC system, and you should know each one of the PLC hardware components is designed to perform a specific function.
By watching this video, you’ll get the answer to the following questions: - How to power a PLC? - What is PLC power supply? - How much power does a PLC use? - How to select power supply for PLC? - How to connect power supply to PLC? - How does PLC power supply module work?
- Typically, the first module is a power supply that comes in different powers and sizes.
- The most common input voltage to a power supply is 120 or 230-volt AC. From this point, the power supply regulates and converts the AC input voltage to the DC output voltage, mostly 24-volt DC.
- To power up all other PLC modules to work correctly, we usually do the wiring between the power supply and each individual PLC component.
- In case of power supply, we need to consider two factors. First, the power supply we choose must provide the power needed for all PLC modules to keep the PLC system stable.
- And secondly, there is no data exchange between the power supply and other PLC components because the main job of the power supply is to provide the power needed by the PLC modules.
#Automatedo #plc #powersupplyWhat is Photodiode? | Explained its Working and ApplicationAutomatedo2022-12-24 | 🎥 A photodiode is a PN junction light-sensitive semiconductor device that when exposed to radiation, produces an electrical current. It means a photodiode receives light as input and generates current as output.
Photodiode vs LED: - The function of a photodiode is the opposite of an LED. An LED is also a diode but makes light out of electricity.
Photodiode Terminals: - There are two terminals that protrude from the end of a photodiode. The cathode terminal is the diode's shorter end, whereas the anode terminal is the diode's longer end.
Photodiode Symbol: - The photodiode symbol is nearly similar to the symbol of the PN junction diode, except that it includes two inward arrows representing light shining on a photodiode. The symbol also indicates the two terminals of a photodiode: cathode and anode.
Photodiode Construction: - If you are familiar with diodes, you know that in a PN junction, the P region majority carriers are holes, and the N region majority carriers are electrons. Also, there is a space in between, called the depletion region, which has no electrons or holes but only includes positive (or donor) ions, and negative (or acceptor) ions.
Photodiode Dark Current: - When the photodiode is under the reverse bias condition and in the absence of the incident light, only a minority reverse saturation current in the microampere goes through the photodiode, called the dark current.
Photodiode Working Principle: - It’s time to shine light over the depletion region of the photodiode to see what happens. If incident photons have enough energy, they can release electrons from the valence band and occupy them in the higher energy band called the conduction band.
- Therefore, we can see a free electron and a free hole have been generated within the depletion region. Because of the movement of these charge carriers, which is the result of throwing light, the electric current, known as photocurrent, is generated in the photodiode.
Photodiode Advantages and Disadvantages: - The main advantages of using a photodiode are low noise, reasonable price, lightweight, small and compact, long lifespan, no need for high voltage, fastest photodetector, mechanical stress-tolerant, and the output current has linearity as a function of incident light.
- The main disadvantages of using a photodiode are the need for external biasing, with a rise in temperature, the dark current increases, the active area is small, and the amplification is needed since the output is low.
Photodiode Application Example: - Finally, let us explore an application where the photodiode is used in an alarm system. Here we have a welding robot, and we do not want anyone to be present when the welding operation is going on since it may cause injury to the personnel.

#Automatedo #transmitter #wiringCapacitors Explained | Types and ApplicationAutomatedo2022-11-27 | 🎥 A capacitor, formerly known as a condenser, is a passive electronic component with two terminals that can store electrical charge.
By watching this video, you’ll get the answer to these questions: - What is a capacitor? - What are capacitor types? - What is inside a capacitor? - How does a capacitor work? - What is a polarized capacitor? - How does a capacitor discharge? - What is a non-polarized capacitor? - What do capacitor markings mean? - How does a capacitor store energy? - What are the symbols for capacitors? - What is a capacitance capacitor unit? - What is capacitor application in electronics? - What is the difference between a capacitor and a battery?
Capacitor vs Battery - The first difference between them is their energy storage. The second distinction between them is their energy density. And the third main difference between them is the charge and discharge rate.
Capacitor Symbols - As an electrical engineer, you should know capacitors are represented in electrical drawings as shown in this video. We will focus on the polarized and non-polarized capacitors symbols
- They always come with two terminals that link the capacitor to the remainder of the circuit. The capacitors symbol is made of two parallel lines that might be flat or curved; the two parallel lines should be close but not touching.
- The curved line in the symbol shows that the capacitor is polarized, implying it is most likely an electrolytic capacitor. Please note that the curved line is a negative side and must be connected to the ground, and the flat one is a positive terminal and must be connected to the power.
- For the non-polarized symbol, which probably indicates a ceramic capacitor, it doesn’t matter which of the capacitor terminals is connected to the ground or power.
Capacitor Markings - One of the characteristics displayed over the larger capacitors, like electrolytic types, is usually capacitance. The capacitance of the capacitor is measured in the farad unit, abbreviated F.
- The other value we usually see on the side of the larger capacitors is the voltage, which is measured in volts, abbreviated V. This voltage value represents the highest voltage that the capacitor can handle.
- In the case of smaller capacitors, such as ceramic models, a shorthand notation is printed over the capacitor body consisting of a three-digit number and a letter, where the digits represent the capacitance in pico-farad and the letter indicates the capacitor tolerance.
Capacitor Structure - If you are curious to know what’s inside the capacitors, regardless of shape and size, it consists of two parallel metal plates separated from each other by an insulating material (dielectric).
Capacitor Working Principle - It’s time to connect the capacitor to the battery. Since we have an electrolytic capacitor here, we should configure which terminals of the capacitor should attach to the power or ground.
- Once we attach the battery to the capacitor, the electrons on the right side get attracted toward the battery-positive terminal. And then, from the battery's negative terminal, the electrons get repelled and pushed toward the left side.
- Since the number of electrons on the left side is more than protons, we consider the left plate negatively charged. And as the number of protons is more than electrons on the right side, the right plate becomes positively charged.
Capacitor Application - What about any fluctuations that may occur in the power supply? It can be deadly to an IC, resulting in the chip turning off abruptly. That’s when a capacitor comes into play to solve this issue.
#Automatedo #capacitor #capacitorsWhat is IIoT? | Industrial Internet of ThingsAutomatedo2022-10-29 | 🎥 Nowadays, we live in the middle of phase 4 of industrial automation, using data to create information. This evolved phase of automation is called Industry 4.0, and its vital technology is the Industrial Internet of Things or IIoT.

- Where you want your team members to be up-to-date and aware of current business and manufacturing procedures, IIoT is needed
- Where you want to increase productivity and profits and enhance client pleasure and experience, IIoT is needed
IIoT Architecture - The edge layer consists of physical components such as sensors and actuators
- The network layer includes IoT gateways, edge routers, or IIoT PLCs that navigate data within the factory
- The cloud layer is the processing engine and data handler, so we call it the core of the IIoT system
- Application layer includes computer-driven industrial applications
IIoT Working Principle - Sensors act as measurement devices to sense process parameters. Data is then broadcast across a network in the factory easily to reach edge controllers
- When edge controllers get data, they serve as the bridge connecting the local network to the cloud. The edge controllers use OPC UA or MQTT protocols to pass data to the cloud
- After the data has been stored in the cloud, you will have the power to monitor and control operations, analyze statistics on industry performance, anticipate upcoming behavior, and use advanced capabilities such as machine learning and artificial intelligence
IIoT Benefits - If any machinery operation faces alarm conditions, the alarm data is sent to the cloud. Then, the information is passed to monitoring systems to deliver immediate alerts to relevant personnel
- Another significant benefit of using the IIoT system is predictive maintenance. In this method, the IIoT monitors attribute to keep track of your equipment's health and set warning and alarm thresholds
- If you want to optimize production, you can count on two advanced technologies in the IIoT system: Machine Learning and Artificial Intelligence
IIoT Challenges - Data integration is one of the main challenges to implementing an IIoT system
- Another challenge is having insufficient knowledge of IIoT integration
- Another challenge is to have a reliable method for testing devices to determine if they are running the most recent firmware version and, if not, for installing new firmware
- Any outage or breakdown in the IIoT system can cause potentially fatal scenarios or significant financial losses
- The top potential risk of implementing the IIoT system is the security issue

- SCADA is made up of both software and hardware elements to create a control system used for industrial automation. It is a centralized system that allows you to keep an eye on a variety of equipment that provides information about particular processes that have become complex for humans to manage.
- Where you need to visualize real-time data on connected equipment located across a plant, SCADA is needed
- SCADA is required where you need a safe environment and want the measurement parameters to be within specific ranges to avoid harmful circumstances.
- Where you want to supervise and control numerous industrial sites while you don’t have sufficient personnel to cover them, SCADA is needed.
- SCADA is a suitable solution for remote operating capability.
- Level 0 includes field devices, such as sensors that recognize operations inputs and actuators that control operations mechanisms.
- Level 1 includes field controllers such as Remote Terminal Unit or RTU and Programmable Logic Controller or PLC.
- Level 2 contains a control center, including a SCADA server alongside SQL database, mobile HMI, and supervisory computer.
- The SCADA function can be divided into four categories: 1. Data acquisition 2. Data communication 3. Data presentation 4. Control
- Since the processing time in the SCADA system is almost fast, it is suitable for time-sensitive processes.
- If security is a priority, then the SCADA system is not a suggested solution
- The SCADA system can anticipate possible failures before they happen and send out immediate warnings to the responsible personnel to fix the issue before it causes serious problems.
- Sometimes, multiple servers are arranged in a dual-redundant configuration to enhance the system integrity.

- In a 2-wire current loop, we have a power supply, a 4-20mA transmitter, and a receiving device such as a PLC analog input module.
- Let us trace the current through this loop. The current goes from the positive side of the power supply to the positive side of the transmitter, which powers up the pressure transmitter.
- Here is where it gets a little tricky is from there, the current goes from the negative side of the transmitter to the positive side of the PLC analog input.
- Then it goes back out of the negative side of the PLC analog input to the negative side of the power supply, and that will make our current loop.
#Automatedo #transmitter #wiringSolenoid Valve Explained | Types and ApplicationAutomatedo2022-08-21 | 🎥 The solenoid valve is one of the inseparable tools of the industry, which is used in a wide variety of applications across many industries. In this video, we will discuss how solenoid valves work. We also cover three types of solenoid valves used in industry and one of the well-known applications in which solenoid valve is most frequently used.
By watching this video, you’ll get the answer to these questions: - What is a solenoid valve? - What are solenoid valve types? - How does a solenoid valve work? - What is a direct-acting solenoid valve? - What is an indirect-acting solenoid valve? - What is a semi-direct acting solenoid valve? - What are the components of a solenoid valve?
- The solenoid valve is an electromechanical actuator that converts electrical energy into a linear mechanical pull/push action.
- We have three main types of solenoid valves based on the operating principle: Direct-acting, Indirect-acting, and, Semi-direct acting
- Direct-acting solenoid valve: For a normally-closed valve in the rest position, the spring pushes down the plunger to effectively block the orifice and prevent the media flow from entering the orifice.
- Indirect-Acting Solenoid Valve: Consider a normally-closed valve as an example. Two chambers are separated by a diaphragm within the valve. A pinhole in the diaphragm where the media can flow from the inlet into the upper chamber, making the pressure equal in both chambers. However, the pressurized media in the upper chamber acts across a much broader area of the diaphragm than the media in the inlet. Therefore, the downward force above the diaphragm is greater than the upward force below it. This high pressure above the diaphragm, together with the presence of the supporting spring, will keep the valve closed, and the media cannot flow. The chamber above the diaphragm is connected to the low-pressure port by a small channel (called a pilot orifice) The plunger blocks this channel in the closed position.
- Semi-direct acting solenoid valve: It combines the characteristics of a direct and indirect valve with the difference that in this type of solenoid valve, the plunger is attached directly to the diaphragm. Take a look at the normally-closed valve as an example. There are two chambers in the valve, separated by the diaphragm. A tiny hole in the diaphragm connects these chambers, causing the pressure in both to equalize. The media in the upper chamber has more contact with the diaphragm than the media in the inlet. So, the diaphragm is forced down towards the valve seat, and as a result, the valve closes.
- Finally, we focus on an industrial application in which the solenoid valve is used as an actuator to control the level of liquid in the tank.
#Automatedo #solenoidvalve #valveWhat is DCS? | Distributed Control SystemAutomatedo2022-07-24 | 🎥 As a control engineer, you know about the challenges that today’s industrial automation systems are facing. So, you can put your trust in a powerful, versatile, safe process control technology that can maximize production asset utilization to get higher efficiency which is called DCS.
By watching this video, you’ll get the answer to these questions: - What is DCS mean? - What is DCS stands for? - What are DCS features? - What is DCS architecture? - What are DCS applications? - What are DCS components? - What is DCS working principle?
- DCS is short for Distributed Control System, but as its term is developed over time, nowadays, the DCS is known as Decentralized Control System.
- The DCS is a computerized control system that coordinates and monitors a whole process or factory that consists of many autonomous controllers deployed across a facility that can handle many continuous operations with lots of analog signals and intricate PID control loops.
- DCS is well-known in the continuous manufacturing processes such as petrochemicals, nuclear power plants, water management systems, and automobile industries, among others.
- A typical facility starts with the integrated operator control center, often referred to as the Operator Station, which is the heart of the system.
- In the next level of components, we find the Server, Archiving Computer (Storage Computer, Historian), and Designing Station (Engineering Station).
- We see the master Controllers (Process Stations) and Supervision and Command units (HMIs) at the next level.
- To measure and control the different parameters in industrial processes, we need instrumentations like sensors and actuators located at the field device level. This level also includes Distributed or Remote IOs that can sense and control digital and analog signals by their IO modules.
- There would be two CPUs instead of one in a DCS control cabinet. One is our primary CPU, while the other is a redundant CPU.
- Because a DCS takes a lot of time to analyze data, it is not the best choice when response times are crucial.
- DCS is a scalable platform, which means it can handle newly installed equipment and data integration to unify the whole control system.
- And at last, relying on DCS will increase the system safety. Because the manufacturer provides both the control and monitoring equipment as an integrated package which minimizes the chances of integration faults.

- The basic PLC hardware components include the following: power supply, central processing unit (or CPU), input and output modules, function modules, and communication modules. Having PLC hardware components together is crucial to make the PLC operates effectively.
- Typically, the first module is a power supply. The most common input voltage to a power supply is 120 or 230-volt AC. From this point, the power supply regulates and converts the AC input voltage to the DC output voltage, mostly 24-volt DC.
- The second module that we are talking about is the Central Processing Unit or CPU. The CPU controls and monitors all PLC system operations especially executing the PLC program based on the status of input field devices so, it can decide what output field devices should do.
- The next component of PLC hardware that we discuss is I/O or input/output modules that connect to different types of field devices. Digital input and output modules connect to the field devices that only have two statuses. These devices are either completely off or completely on. Analog input and output modules can measure or produce a variable signal that lies between a specific range of values.
- Function modules or FMs are another part of PLC hardware use in motion control applications with high accuracy. Whenever the input/output signals consist of high-frequency pulses, the function modules are needed to handle high-speed counting.
- The last, but by no means the least, is the communication modules. Communication modules supply extra communication ports or protocols that an industrial system may need. The communication modules provide additional ports on top of the ports we currently have on the CPU.

- A transmitter is a device that senses the real-world signal from a sensor and converts it into the control signal. A broad range of voltage or current output signals is provided on transmitters. So far, the most frequent analog signal used in industrial applications is 4 to 20 milliamps.
- You should know that several types of 4 to 20 milliamp transmitters wiring exist, and they can be divided into three categories: 2-wire, 3-wire, and 4-wire configurations. These current loops have three things in common: a transmitter, a power supply, and a receiving device such as a PLC.
- In the 2-wire current loop, the current goes from the positive side of the power supply to the positive side of the transmitter. From there, the current goes from the negative side of the transmitter to the positive side of the PLC analog input. Then it goes back out of the negative side of the PLC analog input to the negative side of the power supply, and that will make our current loop.
- In the 3-wire current loop, from the positive side of the power supply, we bring 24 volts to power up the transmitter. Then the transmitter generates its desired signal current, which is the 4 to 20 milliamp signal going to the analog input of the PLC. And as the common side of the transmitter and the common side of the PLC analog input are the same connection, this is the return path of the 4 to 20 milliamp signal.
- In the 4-wire current loop by bringing the power supply voltage to the 4-wire transmitter, we make it operational. The positive polarity of the transmitter milliamp signal connects to the positive polarity of the PLC analog input. Also, the negative side of the transmitter goes to the negative side of the PLC analog input.

PLC Application PLC is short for Programmable Logic Controller and it’s widely used in various industries such as steel, textile, chemical, automobile, oil and gas, and robotics among other industries.
PLC Overview A PLC is a compact industrialized computer that has been adapted for the control of equipment and process in an industrial facility from one location. In another word, PLC is the main key behind almost every automated control process.
PLC Function The functions of a simple PLC can be divided into three categories: Input, Central Processing Unit or CPU, and Output.
1. Reading input: which detects the state of the proximity sensor that is connected to the PLC Input. 2. Executing the PLC Program: based on the information received from the PLC Input, and 3. Writing output: which sends commands to the pusher that is connected to the PLC Output.
PLC Programming Engineers must write a program according to their process requirement, also known as PLC Program, and then download it directly to the CPU of the PLC. The PLC Program is stored in non-volatile memory so it is not lost in the event of a power failure
