Hier erfahren Sie, wie Sie logisches Denken anwenden können, um Ihre Steuerungsstrategien für die industrielle Automatisierung zu verbessern.

Every process in Industry consists of different sub-processes which contains actuator (pumps & valves....) and sensors. Commonly, this process divides into two parts: 1. Control 2. Status We can implement a suitable logic for each part. For example, when the operator decides to start the process, all the signals of those process should be in ready mode and when the operator push start command all the signals relevant to actuator and signals change status.

Lors de notre dernier projet d'automatisation d'une ligne de production, nous étions confrontés à plusieurs options technologiques, chacune avec ses avantages et ses inconvénients. Pour nous aider à décider, nous avons utilisé un arbre de décision. Nous avons commencé par identifier nos objectifs principaux : réduire les coûts d'exploitation et améliorer l'efficacité. Ensuite, nous avons cartographié chaque option, en évaluant les coûts d'investissement, les temps de mise en œuvre, et les impacts sur la productivité. L'arbre de décision nous a permis de visualiser clairement les différentes voies possibles...

O raciocínio lógico é o alicerce da automação na engenharia de controle. Ao utilizar princípios como as declarações "se-então" nos CLPs, os engenheiros podem desenvolver sistemas que reajam de forma inteligente a condições variáveis, como mudanças de temperatura, pressão ou fluxo. Essa abordagem permite a criação de estratégias de controle precisas e eficazes, essenciais para melhorar a eficiência e a confiabilidade dos processos industriais. Ao simplificar ações complexas em passos lógicos, a engenharia de controle não apenas aumenta a automação, mas também a segurança e a capacidade de adaptação dos sistemas às necessidades específicas do ambiente de produção.

I found helpful by understanding what the system requires. Only then you can implement necessary controls to prevent unwanted or adverse reactions. Even with adverse situations, there should be a process to mitigate those mishaps. Every system should be proven before implementation.

Logical reasoning is key for any process control and automation system. It is the basis of which any control system is designed and operated. It tells you the outputs to expect giving certain variables as Inputs into a system.

1. Logical reasoning helps troubleshoot issues faster by breaking down complex problems into simpler components. 2. Analyzing sensor data logically helps identify bottlenecks and optimize production. 3. Applying logical conditions to PLC programming prevents costly errors and ensures consistent product quality. 4. Logical thinking helps design intuitive HMI screens for operators to easily monitor and control processes. 5. Logical reasoning enables creating predictive maintenance strategies to minimize downtime.

The use of operators such as AND, OR and NOT operators in PLC programming is very important because it gives you the flexibility to create interlocks for easy and smooth process operation with less or no effort from operators. They also help to ensure safe and reliable operation. For instance if an elevator motor will only be ready to run when a high high level switch is not activated and the last conveyor motor is also running then the only means to achieve this is through the use of these three critical operations

Totally agree, as the use of logic operators is very crucial to design a simple logic system and to ensure safe process and operation under certain circumstances.

O uso de operadores lógicos como AND, OR e NOT na programação de CLPs é essencial para garantir que as ações de automação sejam executadas com precisão e confiabilidade. O uso de operadores lógicos na programação de CLPs não só simplifica o controle de processos complexos, mas também permite uma adaptação mais ágil a diferentes cenários operacionais, garantindo uma produção mais consistente e confiável.

I agree. Each systems can be designed to specific function or functions. There are always ways to upgrade a system that isn’t working. If the systems logic are built only to do an AND, or OR functions and it is not working the way you wanted to be, you can manipulate each logic such as combining both logics to satisfy what you are trying to achieve. There is always room for improvements. Although, you have to justify your financial capabilities on how much you’d like to spend.

It is plausible to state that logical reasoning is essential for faut analysis and troubleshooting. Nevertheless before one starts working on a system or a problem, such a person should have a good understanding of how the system operates either through experience or a manual or a well designed diagram for guidance. For example there's a process that controls a temperature of let's say a steam and the control valve doesn't open again but there's power available at its terminal. One has to understand that this control system has a sensor ( temperature sensor), controller (PLC) and actuator (valve). So with this knowledge one can troubleshoot systemically and also help reduce downtime

Ao aplicar um raciocínio lógico estruturado, os profissionais podem reduzir significativamente o tempo necessário para diagnosticar e corrigir falhas, garantindo assim uma rápida retomada da produção e minimizando o tempo de inatividade. Além disso, essa abordagem aumenta a confiança na precisão das intervenções realizadas, promovendo uma manutenção mais eficiente e preventiva no longo prazo. Portanto, o raciocínio lógico não apenas ajuda a resolver problemas de maneira eficaz, mas também fortalece a capacidade dos engenheiros de entender profundamente o comportamento dos sistemas automatizados, melhorando assim sua capacidade de manutenção e otimização contínua.

By understanding how the system is designed and knowing the materials or devices manuals, troubleshooting becomes less troublesome. Instead of spending time going through each ways the system is connected to figure out the issue or issues, you can divide and conquer where it eliminates certain parts of the system that doesn’t need to be checked/ verified. This way, you can save time on troubleshooting. You can spare those saved times on different matter.

For fault analysis and troubleshooting you have to understand well the system behavior first (process, sensors, transducers, etc). This might be very important to troubleshoot any fault in the logic sequencing.

J'ai été impressionné par les fonctionnalités que l'API offrait. La programmation en langage ladder était intuitive sur le module Zelio logic de Schneider, et les outils de simulation ont permis de tester les séquences avant de les déployer sur les turbomoteur. L'un des principaux défis était de synchroniser plusieurs machines sur la ligne. Grâce à des fonctions avancées de l'API, comme la communication en temps réel entre les unités, nous avons réussi à optimiser le flux de production. Cela a réduit les temps d'arrêt de 60 %... De plus, l'intégration des capteurs et des actionneurs a été facilitée par les entrées/sorties modulaires du PLC, ce qui a rendu le câblage beaucoup plus simple...

Every decision in a given organization or system should have a strong management skills taking accounts of what’s happening inside and outside of their control. This way, you can plan according when or if something happens.

Using simulation tools is very important before installing and commissioning the PLC on site. You will be able to detect any fault on PLC programming, sequencing or communication. This saves time and cost during installation and commissioning and protects the process and the equipments.

A great way to implement something is to test and verify that each components, people, and tasks are understood and supported by who’s involved. Being able to test and verify a policy or a system is a great way to prove that it is proven to be effective.

Yes logical reasoning is very effective method in any scenario as it increases curiosity and we understand why we do what we do and questioning each scenario. Also it holds the answers to many questions and refine not only automation strategies but an individual as well who strives to give better performance.

Lors de l'intégration d'un PLC pour notre ligne de production secteur broyage (Turbomoteurs+Pignon), j'étais préoccupée par la transition. Rapidement, j'ai découvert la flexibilité de la programmation. L'interface intuitive m'a permis de créer et tester des séquences facilement. En optimisant nos capteurs de niveau, nous avons réduit le gaspillage de matière, augmentant l'efficacité de 42 %. De plus, la fonctionnalité de diagnostic à distance a diminué nos temps d'arrêt. Nous pouvons maintenant résoudre rapidement les problèmes. Cette automatisation par PLC a transformé notre production et est devenue essentielle pour notre compétitivité...
