I have personally witnessed the successful transition of two mechanical engineers into the field of instrumentation, automation, and controls. They were both highly respected and achieved great success in their new roles. One of my colleagues, who originally worked as an electrical engineer/designer, self-taught himself PLC programming and made a career switch to become a controls engineer with us. It is important to invest time in reading relevant books, following tutorials, and attending vendor training sessions to stay updated with the latest trends in the industry. Ignition University offers valuable resources for learning about SCADA software and its functionalities. Automation Direct in the United States is a recommended source for cost-effective PLC/PAC hardware and software solutions. If your background in engineering did not cover electrical and electronics basics, it is essential to fill in those knowledge gaps now. Do not hesitate to ask questions and seek guidance from experienced professionals in forums like this one. Wishing you the best of luck in your career endeavors!

Have you had previous experience with programming? The initial step is mastering the skill of breaking down complex problems into smaller, more manageable segments. This skill is crucial to develop and can only be honed through consistent practice. Understanding programming logic is essential for reviewing and analyzing your work, and there are numerous free Codesys resources available online to help you get started. For those interested in learning about Siemens programming, consider checking out hegamurl on Youtube. Codesys is a great option as it can be run directly on your laptop for demonstration purposes. While German brands may be the next natural progression, it's important to note that they often come with a price tag. Fortunately, Codesys shares similarities with Beckhoff and Siemens, making it easier to apply similar concepts. Keep in mind that programming knowledge shouldn't be limited to just one language. Mastery of multiple languages, along with understanding their individual strengths and weaknesses, is what sets apart competent programmers from the rest. When it comes to practical applications, traffic light control systems for intersections are a common project to work on. Ensure that your programming accounts for factors such as lamp status measurement and fault detection. You can also add intelligence by incorporating sensor inputs to identify traffic congestion and adjust opening times accordingly. Don't forget to create simulation logic to test your programming solutions. If you prefer working on processing tasks, consider projects like designing a car wash machine or an industrial soup maker. Begin by programming blocks for each process device, such as proportional valves, solenoid valves, motors, VFDs, and analog inputs, as well as developing simulation logic. With a background in electrical engineering, the transition to programming PLCs may seem natural. Further your knowledge by exploring SCADA systems, and platforms like Inductive University can be a valuable resource. Best of luck on your programming journey!

If you have any valuable insights to share, please contribute, and I will credit you. To start, it's important to understand and follow the specifications for any project, treating them as customer requirements. Here are some guidelines to ensure successful implementation: 1. Carefully read and review the specifications multiple times. 2. Write down a detailed understanding of the specifications in a step-by-step manner. 3. Review your notes and make modifications if necessary. 4. Collaborate with the mechanical designer to address any differences in opinions or operations, ensuring alignment on all points before proceeding. 5. Step through your notes as if you are the PLC, documenting each action taken. 6. Continue following the instructions and make necessary updates as you progress. 7. Ensure all sensors, motor auxiliary contacts, and outputs are documented and make adjustments as needed. 8. Repeat the process until no further modifications are necessary. 9. Organize your data in a structured manner as you write the PLC program. 10. Document all steps thoroughly, anticipating the need for revisions or enhancements. 11. Maintain open communication with maintenance personnel and incorporate their feedback to facilitate troubleshooting and program understanding. 12. When installing the program, leave it in program mode if possible for debugging purposes. 13. Utilize detailed notes from previous steps when creating instruction manuals, using clear language and specifying I/O, timers, counters, and outputs. 14. Understand the potential dangers of powering on a machine and PLC for the first time, as wiring configurations may not be known. 15. Carefully debug the program to ensure it functions as intended. 16. Be prepared to address any potential scenarios, no matter how unlikely, to avoid issues during production. 17. Consider incorporating subroutines into the main program for better organization and efficiency. Overall, maintaining clear documentation, fostering collaboration, and adapting to feedback are key principles in successful PLC programming.
