Se enfrenta a plazos de fabricación ajustados. ¿Cómo se optimiza la programación de PLC para obtener la máxima eficiencia?

One of the most overlooked elements is the demolition of the original system. I am speaking strictly as a retrofit, the demolition and the care required to remove the old system, and the necessity to capture and document the missing information from the original design, even if the schematics exist. Based on experience, I suspect that there is a 25% deviation from the original design that has never been documented. We, as designers, are often motivated to write the code and get ahead, but contingency planning matters in optimization, especially if tight deadlines are involved.

Steps that have proven useful to me: 1. Thoroughly read and understand the process and its requirements of control. 2. Write steps for logic and identify crucial points in logic. 3. Map down all the I/Os before writing logic. 4. Try to make functional blocks for recurring logic steps to save time. 5. Use a simulator for testing logic before hand to avoid any unpredictable scenarios.

Always read THOROUGHLY through your schematics & drawings to ensure proper execution of the job being performed. There are always plenty of resources around your job area as well! Never be afraid to look for information & ask questions!

I am no expert, only using PLC's for home projects to get a better understanding of them & how they work. I mostly used esp boards & relays for Home Automation, but as long as you know what you are trying to accomplish & research the PLC that you want to use for your project, as well as the limitations of the program, you should be good. The only caveat I have found is the life of the board because of Monday or Friday production days.

Action: Review project specifications, define clear objectives, and map out the control logic before starting any programming. Why: Having a well-thought-out plan avoids confusion during programming, reduces errors, and ensures the project stays on track. Proper planning minimizes delays by identifying potential bottlenecks early.

Action: Use standardized programming practices and templates across projects. Why: Standardized code makes it easier for engineers to understand, modify, and debug, regardless of who originally wrote it. This approach enhances collaboration, simplifies maintenance, and reduces programming time on future projects.

Action: Create reusable function blocks or code modules for commonly used logic sequences. Why: Reusing pre-built blocks eliminates the need to program everything from scratch, saving time and reducing the likelihood of errors. It’s especially useful when dealing with similar systems or processes.

Action: Analyze and simplify control logic, removing redundant steps or unnecessary complexity. Why: Streamlined logic ensures that the PLC operates efficiently, reducing processing time and increasing system performance. Clear, concise logic is easier to test and troubleshoot, speeding up the development process.

Action: Work closely with mechanical, electrical, and other engineering teams to ensure alignment on system design and functionality. Why: Cross-team collaboration prevents miscommunication and ensures that all aspects of the system are fully integrated. Early problem-solving avoids rework, saving time and effort.

Action: Develop automated testing scripts or simulation models to verify the PLC logic. Why: Automated testing can quickly identify logic errors or unexpected behavior, reducing the time spent on manual testing. It speeds up the validation process and ensures the system works as expected before deployment.
