Can ChatGPT Help to Write PLC Programming

Ever stared at your screen, wondering why a piece of code refuses to work despite looking perfect? You’re not alone.

Programmers, from beginners to pros, often struggle with tricky bugs, confusing errors, and the constant need to learn new languages. It’s like solving a puzzle where the pieces keep changing shape.

Computer technology has changed the way to operate the workings of industries by making processes more easy, reliable, and accurate. Programming logic controller (PLC) is the heart of modern computer systems and is used to operate machines, computer systems, and other machinery. PLCs are a critical part of our industries that range from manufacturing to water treatment and energy production.

PLC programming is not a child’s play. It requires some kind of special knowledge, hours of dedication, and a focused mind to operate the systems. That’s the point where ChatGPT comes in and makes your work simple and easier. Can ChatGPT help to write PLC programming and be used in troubleshooting? This post will help you understand how AI tools like ChatGPT make it valuable to write a PC code without dedicating a lot of time.

What is PLC programming?

A programmable logic controller (PLC) is a strengthened computer designed to operate industrial processes. PLCs are used to handle the critical conditions found in factories, like extreme temperatures, moisture, vibration, and electrical noise. It uses well-defined, programmed instructions to control machinery, processes, systems, and modern computers.

PLC programming is a process in which we write a code that tells PLC what task to perform. This code usually involves “ladder logic,” which is a graphically programming language that looks after electrical relay diagrams. In past times, a more textual form of programming had become a popular option for more critical automation.

Real-World Applications of PLC Programming

• Control in assembly lines: In a car manufacturing industry, PLCs control the group of vehicles on a conveyor belt. As in industry, different parts of machines pass through different stages. PLCs manage tasks like gripping, moving items, controlling the flow of the assembly line, or even tracking the product speed.
• Management of factory equipment: PLCs can be used to regulate ovens, mixing machines, or packing equipment in the food industry. The system can adjust temperature and turn the machine on and off. It can also ensure that everything is running according to the data you have already set.
• Management of energy systems: In power plants, PLC control turbines, generators, and boilers. They control critical components based on data to optimize energy generators and also ensure safety.

In each of these cases, PLC programming is crucial for reliable, continuous operation. A single mistake in the code could result in system failure, and the result could be default. These points make PLC programming essential for anyone working in industrial automation.

How ChatGPT Helps to Write PLC Programming

Can ChatGPT help to write PLC programming? Yes, ChatGPT is a powerful assistant to write and improve PLC programming. We have to check how it helps, from generating sample code to simplifying explanations and enhancing the overall programming process.

Generating Sample Code for PLC Languages

When you start writing a new programming code, ChatGPT can provide sample code in some PLC programming languages like ladder logic and functional block diagrams.

Example

If you have to write a PLC program to control a motor using a start and stop button. You can simply ask ChatGPT to write a basic ladder logic program to control start and stop operations.

Simplifying Syntax Explanations and Debugging

Those who are new to PLC programming syntax can be tricky, especially in structured text or instruction lists. This is the point where ChatGPT takes a roll to improve complex syntax into easy terms.

Example

You don’t understand a CASE statement in structured text. You can simply ask ChatGPT, and it will try to explain as simply as possible.

Helping with Logic Design, Troubleshooting, and Documentation

ChatGPT greatly helps in logic design and as well in troubleshooting in case of an error. ChatGPT is a very versatile tool; you can use it as you see fit, and it will tell you the solution to all of your problems.

Logic Design

If you are using a conveyor system, then simply ask ChatGPT to help you outline the logic:

• When an object is detected by a sensor, the conveyor is started.
• Stop it after 10 seconds or if an emergency button is pressed.

ChatGPT can write the program for this, and it even suggests the pseudocode or diagram to help you visualize the process.

Troubleshooting

Debugging can be boring and mind-numbing. ChatGPT helps by analyzing your code by pointing out mistakes, potential issues, and corrections of mistakes. If your motor is not starting, share your code with ChatGPT, and it can easily detect missing conditions or incorrect logic.

Documentation

Writing good documentation is critical for PLC programming. ChatGPT can help you write a clear explanation of your code by making it easier to understand for others.

Example

• Input descriptions
• Output functions
• Sequence explanation

In Action

If you are operating a temperature control system, the following is a procedure to generate relative output from ChatGPT.

• Generate a code for maintaining temperature with a specific range.
• You have to mention the temperature range, and ChatGPT will write you a PLC program to maintain temperature.

Benefits of ChatGPT for PLC Programming

Using ChatGPT for PLC programming can bring many benefits; it is usually used for professional-looking enhanced coding and also for skill development. Let’s see how this tool makes programming easier and more manageable.

Solve problem faster and instant code generation

ChatGPT can make code or logic ideas based on the programming description of a task in a short time. It saves a lot of time when you are facing day-to-day programming challenges.

Example

• Give ChatGPT only 10 seconds after you give it a prompt.
• The output of that prompt will come and go, ready for direct use.

Reduction in error

Debugging a code can be the most time-consuming for PLC programming. ChatGPT can help with the correction of your code and will suggest better logic structure. Prompt web pages for effective content creation and reduction in error of PLC program also exist.

Example

• It identifies mistakes in your code according to your prompt.
• It will recommend reliable and simple logic code.

ChatGPT’s Drawbacks for PLC Programming

ChatGPT can outstandingly detect mistakes in many areas of PLC programming, but it is not fit for all solutions. Understanding the limitations of ChatGPT is so crucial. Following are the challenges that we have to face while fetching data from ChatGPT for PLC programming.

Situations Where Human Expertise is Irreplaceable

While writing a PLC program, having deep knowledge about the industry and understanding of unique system requirements is very essential.

• Unique machinery requires unique PLC programs, such as sometimes custom robotics, and exclusive manufacturing equipment requires complex logic and hardware configurations that require on-site testing and repetitive refinement.
• During production, unexpected challenges like hardware faults, communication lags, and environmental impacts can arise. Experts use domain knowledge and hands-on testing to clear these unpredictable issues. 

PROMPT EXAMPLE

• Prompt for Basic ladder logic code

You are an expert PLC programmer. Your task is to write a ladder logic program for controlling a motor. The motor starts when a start button is pressed and stops with a stop button. Include interlocking logic to prevent accidental restarts. Make your words simple and add human touch.

• Prompt that sets timer function in PLC program

Act as a professional PLC programmer. Your task is to explain how timers work in PLC programming. Write a structured code snippet to activate an output for 10 seconds when an input is given. Provide clear comments within the code to make each line easy to understand.

• Prompt to detect fault for PLC program

You are a creative PLC programmer. Create a fault detection logic in ladder diagram format. When a motor fails to start after 3 seconds of activation, also display a fault signal and stop all outputs. Also give details on how this logic works in practical PLC programming.

•  Prompt for Troubleshooting Timer Errors

You are a professional PLC programmer. Today your task is to help me debug a PLC timer issue because my motor doesn’t stop after the timer expires. Also suggest possible reasons for this error in ladder logic. Write the correct ladder logic and provide an explanation for the fixing of the problem.
