PLC Programming Languages: Ladder Diagram & Function Block Diagram
🎥In this video, part 1 of the PLC programming languages, we will cover the essential features of Ladder Diagram and Function Block Diagram languages. You'll gain an understanding of their core structure, advantages, disadvantages, and the scenarios in which they are most suitable.
======================================================
💬 Video Summary:
What is a PLC?
- A Programmable Logic Controller or PLC is a small, industrial computer engineered for supervising equipment and processes in industrial settings from one central location.
A PLC requires programming in a particular language and downloading the program directly into the PLC CPU to function correctly.
PLC Programming Languages Types
- Under the IEC section 61131-3 standard, there are five programming languages utilized for different PLC hardware platforms, namely Ladder Diagram (LD), Function Block Diagram (FBD), Sequential Function Charts (SFC), Structured Text (ST), and Instruction List (IL).
Ladder Diagram Basics
- Ladder Diagram serves as a graphical, top-level PLC programming language. The Ladder Diagram is the initial programming language for PLCs, evolving naturally due to its close resemblance to electrical relay circuit schematics.
- A Ladder Diagram is arranged as horizontal lines, known as rungs, with two vertical bars at either end called power rails.
- The input instructions, called contacts, are located on the left of each rung. The right side features output instructions, known as coils.
- The reading direction is first from the left side to the right and then downward from the top.
Ladder Diagram Advantages
- The Ladder Diagram's capability for online editing enables users to make real-time modifications to the control logic of a running system, all while ensuring that the system continues to operate smoothly without any interruptions.
Ladder Diagram Disadvantages
- In the Ladder Diagram, the absence of specific instructions can introduce complexities, potentially making programming operations such as motion control procedures challenging.
Ladder Diagram Application
- Ladder Diagram emerges as a premier programming language for systems that manage extensive and complex Boolean logic.
Function Block Diagram Basics
- FBD relies on standardized blocks whose purpose is to determine the relationship between the input and output statuses. Function Blocks sit on a workspace sheet where they are linked to one another through lines of connection.
Function Block Diagram Advantages
- FBD offers the benefit of consolidating various programming lines into single or multiple functional blocks, thus streamlining the design process and enhancing organization.
Function Block Diagram Disadvantages
- Programming in FBD can be messy. If blocks are not placed in an organized manner on the sheet, it can quickly become a confusing mess, making it hard to grasp what's happening.
Function Block Diagram Application
- FBD works well with continuous process management, repetitive tasks with regular code usage, systems needing motion control, and PID control mechanisms.

Does DCV Supply matter if Full or Half wave?
A full-wave rectifier provides a smoother DC voltage compared to a half-wave, which might result in less ripple and more stable operation for sensitive equipment like transmitters 🤖✨

I am learning and I start to understand, but then i get brainfreeze when i see minus connected to both connectors on the motor. So I guess I dont understand
The negative (ground) connection is typically shared across the motor, controller, and power supply, which is why it may seem like it's connected to both ends. The potentiometer just adjusts the control signal, while the motor's negative terminal is common to all parts of the circuit 🤖✨

Can I use a potentiometer to control the speed of a bldc motor?
Yes, you can use a potentiometer to control the speed of a BLDC (Brushless DC) motor, but you'll need a motor controller that supports analog input for speed control.

More information would be appreciated in understanding how the three prong set up is used as a voltage divider. does the circuit require a diode to the back wire to direct current through the potentiometer? would it not just bypass the potentiometer in the circuit? And if the current flow doesn't bypass the potentiometer doesn't that mean the current is flowing through the entire resistive strip to connect the circuit from the negative and positive terminals of the pot?
Great explanation but the topic is confusing! 😟
Thanks for your feedback! 😊 We totally get that the topic can be a bit confusing at first - potentiometers have a lot of details to understand.

Thanks for the instructions. Could you provide us with a couple of programming software that we could use to practice writing programs for both LD and FBD? Many thanks for considering my request.
Thank you for your kind words! I'm glad you found the tutorial useful. Siemens TIA Portal: This is user-friendly software for Siemens LOGO! PLCs that supports both LD and FBD programming. It's perfect for beginners and allows you to simulate your programs before deploying them. CODESYS: A widely used PLC programming platform that supports multiple programming languages, including LD and FBD. It’s free for practice and works with virtual PLCs for simulation.
4:22 Can you tell me how its opens the power contact while it turns from NO to NC which means the contactor is energies. I'm lil confused.
That means this relay is automatic. We don't need to reset it ??
3:12 I understood till you said that inner alloy melted. So, it enables the inner ratchet shaft. I didn't understand 😕 that. How it works.. what leads to move the ratchet shaft.
You have really good tutorials, please continue
Thanks for the encouragement! We're glad you're finding the tutorials helpful. 😊
Teşekkür ederim.
You're welcome! 😊 We're glad we could help!
This was a great video. I'd like to see you do more videos on the various protocols out there. The BACnet/IP, MSPT, and others, to demonstrate networking, data storage, graphics rendering and controls of industrial automation in facilities.

Hi thanks for the great video. I was just wondering. Can you put just two hot wires from a two pole fuse holder to a three pole overload relay (ex. L1✓ L2✓ L3×)?? Thanks again
Yes, it’s possible, but always verify the relay’s manual or technical sheet for specific instructions on using it with fewer than three phases. And as always, ensure proper wiring and safety measures during installation! 😊 If you’d like a diagram or additional clarification, just let me know! 🚀
@@Automatedo Thanks I will. So I got an electrical manual for a back panel and a qps Personnel asked me to fuse the primary and secondary of the single phase step down transformer in it. In the manual the circuit breaker of the primary of the transformer has a rating of 15A/5KA labelled for it? What is the 5KA signify? Is that the rating of the breaker or is it 15A? The secondary is connected to the 200V terminal and has a 9A in the manual. Is that the one I have to fuse? I have a main supply of 208V 3Ph for this machine.
Thanks sir🎉
You’re very welcome! 😊🎉 I’m glad I could help! If you have more questions, feel free to ask anytime. Keep learning and exploring! 🚀📚✨

Which configuration to use for audio volume control? Would the 2 wire solution be sufficient?
For most audio volume controls, the 2-wire potentiometer should be enough. It will allow you to adjust the audio signal's amplitude without needing the extra complexity of a 3-wire setup. 😊 If you're setting up a circuit for a more advanced audio system or specific equipment, you may want to consider other factors, but for basic usage, the 2-wire is perfectly fine! 🎶
