Is there anyone using a software program like CODESYS that supports fuzzy logic? I particularly prefer Structured Text due to its readability and ease of modification. If anyone has a pre-existing Function Block for this purpose, I would greatly appreciate it. Why reinvent the wheel when a solution has already been developed?
**Inquiry from Shooter:** Is anyone using programming tools like CoDeSys that can implement fuzzy logic? I prefer using Structured Text due to its readability and ease of modification. If anyone has a Function Block available for this purpose, I'd greatly appreciate it. After all, there’s no need to reinvent the wheel when a solution already exists. **Response to Shooter:** Hello Shooter, I’ve developed a fuzzy logic Function Block specifically for the Wago 750-841 PLC, which has proven effective for my specific application. However, you may need to customize it to fit your own needs. Please feel free to utilize and modify the code as you see fit—just keep in mind that I cannot be held accountable for any unintended outcomes. I've saved the Function Block as a CoDeSys export file in a ZIP package, which you can easily import into a new CoDeSys project. Best regards!
Thank you, Mister K. I reviewed the project, and while there are several conditional statements (IFs) present, overall, it looks impressive and functions well. Additionally, it's not overly fuzzy; it’s more of a zone issue. The initial setup is strong, and I plan to use it. I even printed it out. One observation I’d like to make is regarding the membership aspect. I suggest changing the fixed numbers, like 1000 and 500, to variables instead. This adjustment will help avoid complications during compilation and reduce the fuzzy results caused by fluctuations.
I am working on a temperature control application for a cream mixing vessel. What input parameters should I set for your fuzzy controller if I aim to achieve a setpoint (SP) of 60 degrees Celsius with an approximate hysteresis of 2 degrees Celsius? Additionally, what parameters should I use for a setpoint of 40 degrees Celsius?
You can easily enter the temperatures directly, specifically 600 and 20. The output can be effortlessly converted into a Word document.
Fuzzy unther CoDeSysKP_EENG stated: "Shooter, I have developed a fuzzy logic function block designed for the Wago 750-841 PLC. This function block performs exceptionally well in my specific application; however, you may need to adjust it to meet your unique requirements. You are welcome to use and modify the code as needed, but please note that I cannot assume any liability for unintended outcomes. I have saved the function block as a CoDeSys export block within a ZIP file, allowing you to easily import it into a new CoDeSys project. Best regards." Additionally, I would like to ask: has anyone managed to implement this in CoDeSys V3? I am currently developing a system using a Raspberry Pi and have the CoDeSys software for Raspberry Pi installed. Regards.
I've used CODESYS with fuzzy logic applications, and I totally get where you're coming from—Structured Text really does make it easier to handle the logic without getting lost in the details. While I don't have a pre-built Function Block to share, I've come across some libraries online that could be a good starting point for your projects. It’s definitely worth checking out the CODESYS forums and GitHub; there might be something out there that fits your needs perfectly! Plus, collaborating with others can lead to even better solutions.
I haven't found a specific pre-existing Function Block for fuzzy logic in CODESYS, but I've seen some users in forums share their own implementations that might be worth checking out. If you’re comfortable with Structured Text, you could adapt one of those examples to suit your needs, as many of them are pretty modular. Also, don’t forget to look into library resources in the CODESYS environment; there might be some hidden gems that can save you time!

Answer: - Yes, CODESYS does support fuzzy logic, but it might require creating custom solutions or integrating third-party libraries since built-in support may not be directly available.
Answer: - Yes, you can implement fuzzy logic using Structured Text in CODESYS. Structured Text is a high-level, block-structured language that is ideal for complex algorithms like fuzzy logic due to its readability and ease of modification.
Answer: - While CODESYS may not have built-in Function Blocks specifically for fuzzy logic, there might be community-contributed libraries or third-party solutions available. It is always a good idea to check the CODESYS Store or forums for shared resources.
Answer: - Using pre-existing Function Blocks can save time and effort as they are often tested and optimized by other users. This allows you to focus on integrating and customizing them to fit your specific application needs rather than starting from scratch.
Answer: - You can look at the CODESYS Store, C
