=============================
PLCs are essential components in modern control systems. Understanding the basic components of a PLC is crucial when it comes to troubleshooting and maintaining these systems.
In this video, we will review the fundamental components of a PLC and explore some basic and advanced troubleshooting techniques.
- CPU is the brain of the PLC and is responsible for processing the logic and making output decisions based on the inputs received. The processor executes the code stored in memory and controls the operation of the I/O modules.
- The power supply provides the necessary voltage and current to power the PLC and its components. Without a stable and reliable power supply, the PLC would not function correctly and can experience errors, faults, or even complete failure.
- I/O modules are responsible for communicating with the external devices in a control system. Input modules receive signals from sensors and output modules receive signals from the processor and convert them into signals that can control devices.
- Communication modules enable the PLC to communicate with other devices such as other PLCs, HMIs, SCADA systems, or other relevant devices. These modules typically use protocols such as Ethernet or Modbus to exchange data with other devices.
To effectively troubleshoot, start by gathering as much information as possible. Pinpoint the problem by identifying a specific system or component. Troubleshoot by using trial and error methods and recording the outcome of each alteration.
Once a solution is proposed, be cautious when implementing changes and consider adverse effects. Verify and test the solution, then take careful notes and notify appropriate individuals to prevent future issues.
During this process, it is crucial to use resources such as official vendor documentation, operation and maintenance manuals, and functional design specifications.
Online resources can provide helpful tips and solutions from other professionals who have encountered similar issues.
It is common to experience issues with wiring in a control system. You'll want to check for correct wiring throughout your PLC and control system.
You’ll also want to pay close attention to the main PLC components.
Verify that your power supply is working properly, your I/O modules are wired correctly and that they have been configured properly in your programming software, and that all PLC communication is wired up right and configured correctly.
Examine the program logic. This means looking at the ladder logic, function blocks, or structured text in your PLC program to see if there are any errors or issues.
By carefully monitoring the system, you can detect patterns that can reveal issues to help you toward a solution during troubleshooting. This can be done through a variety of tools such as trending, alarms, and event logs.
System audit involves reviewing the system's design and configuration by examining the system's documentation, checking wiring and cable connections, verifying settings on devices, and diving into the nitty gritty details of the PLC program.
PID loop tuning is another technique that can be used to optimize the performance of a control system.
PLC program debugging is also a useful tool when working with more complicated PLC code. Program debugging is a methodical approach to problem-solving and often involves taking steps through the code to pinpoint where errors are occurring.

Real pars is the best organization on automation education. You guys are on a league of your own. More troubleshooting please.
Thanks a million! We truly appreciate your support.
@@realpars I actually realized that you guys have a whole course on your website on the topic. I have done the first part. Can't wait for the second part.
@@realpars p
You guys are fantastic!
Amazing tips for PLC troubleshooting 101..very good solution
Glad it helped, happy learning!
Lovely Tip and Trick thank you somuch
Glad to hear that!
Thank you for sharing valuable trouble shooting information
You're very welcome!
Thanks for teaching
Our pleasure!
Thanks for another helpful video. I say " Keep It Up " ❤
Thank you, happy learning!
Thanks for useful information..
You're very welcome!
ELDER COCINA!!!! Good video...
Very Useful information, Thank you
Thank you for sharing! Happy learning
You make wonderful informative videos..😍
Keep it up😎
Thank you so much!
Plz make more videos on this topic
Excellent explanation
Glad it was helpful!
Your All video is very helpful ..❤❤
Thank you!
Thank you so much!
You're more than welcome, Kevin! Happy learning
@@realpars I feel happy reading this message of yours. 🥰
@@realpars I want to learn about the structure and working principle of some basic PCBA, can you help me?
As always 🔥🔥🔥
Please make more content on PLC
Sure, we will! We do have a large section on PLC Programming courses on our learning platform, feel free to check those out over here. www.realpars.com/courses
Happy learning!
What’s the first thing to do? Thumbs up! because I’m 100% sure always will be a great video
You're the best! Thank you for your support
Sir can you create a video with detail parts and how to read plc diagram and interpret it
Thanks for your topic suggestion, I will happily go ahead and forward this to our course developers.
Happy learning!
Pretty good.. What is the name of the tool used to create this video?
Thank you! Regarding your question, I am actually not completely sure, as this is created by our graphic and animation department.
@@realpars oh ok.. But i need the tool name.. Coz i'm in search of tool to create a animation video about my project
Hey ,how do I get the realpars app?
Hi Andrew,
We have recently optimized our learning platform which includes some highly requested features. We are happy to bring you these new improvements which will grant an even better learning experience, as a result we had to decide to no longer support the RealPars App. You can use our webpage to continue watching the video courses.
Hope this helps!
Troubleshooting by using Trial and Error method! You must be out of your mind. Using the logic mindset to trace the error and solve the problem.
In the real world I’ve used both and not blown anything, anyone or myself up to date.
It’s usually easier to have the ladder logic running on your laptop when the process is running to see where your fault is.
Failing that, if it’s an Allen Bradley SLC 500, take out the I/O cards and reseat them. 😂😂😂
@@PHealey1981 Do you know the anecdote about three engineers in the car that wouldn’t start? 😂
@Commenter yes, brilliant it is too! 😂😂😂
@@PHealey1981 Yeh! Late just get out and come back again! 😂
@Commenter 😂😂😂🤣🤣🤣👌👌👌

Lol, the illustration showing an output module going directly to a motor made me laugh a little.... In actuality, it's going to some type of device which CONTROLS the motor, likely a starter or a vfd or soft stat ✅😊‼️...It could be a servo motor though too, to be honest.
