1. Understanding the Feasibility of Self-Learning PLCs
Many aspiring PLC programmers begin their journey by dedicating time to practicing programming at home, often before securing their first industry role. The crucial question isn’t just about learning, but whether you can transition from an unrelated field, like a production line worker, to a successful career in industrial automation through self-study. Let’s explore how individuals already in the field have started and how you can emulate their success.
1.1. The Common Path: Home Study Complements Formal Training
Many engineers and technicians who program PLCs have spent considerable time learning at home. While they may have had initial lessons during seminars or workplace training sessions, their dedication to home study has been crucial for mastering the craft. If professionals in the field supplement their formal education with self-directed learning, there’s no reason you can’t do the same.
1.2. The Real Question: From Unrelated Job to Automation Expert
The key question isn’t just whether you can learn PLC programming at home, but whether someone with no prior experience can train themselves and land a job as an automation engineer or technician. This is the core question we’ll address.
2. Building a Portfolio: Showcasing Your Skills
How do you demonstrate your capabilities without prior professional experience? The answer lies in building a robust portfolio. A strong collection of your work can effectively showcase your abilities to hiring managers, recruiters, and HR professionals, proving you have the skills to excel.
2.1. The Power of Today’s Technology
We live in an unprecedented era of technological accessibility. The internet, software, and readily available computers offer unparalleled opportunities for self-education. Even if you currently work an unrelated job, such as a lift truck operator, you can leverage these tools to transform your career.
2.2. Sparking Your Interest in Automation
Imagine meeting a controls engineer who sparks your interest in the field. After learning about their work and potential salary, you’re motivated to pursue this path. While education requirements might seem daunting at first, you discover that a formal degree isn’t always necessary to become a programmer.
2.3. Online Resources: Your Learning Hub
Fortunately, numerous excellent online training programs are available. You can learn after work, fitting education into your existing schedule. With clear goals, accessible education, and the ability to learn online, the path to becoming a PLC programmer is within reach.
2.4. Showcasing Your Abilities Through Examples
By creating a strong portfolio of your work, you can demonstrate to employers that you possess the necessary skills. This hands-on approach to learning and showcasing your abilities can be incredibly persuasive.
3. Finding Projects for Your Portfolio
Where can you find projects to build your portfolio, beyond the exercises in your training programs? The answer lies in real-world applications and contract work.
3.1. Contract Work: Getting Paid While You Learn
One of the best ways to find real-world projects and get paid for your work is through contract opportunities. Platforms like Guru.com, Freelancer.com, and Upwork.com list jobs/projects where programmers are needed. Many of these are well within the grasp of beginners.
3.2. Online Communities: Networking and Opportunities
Engage with online PLC programming communities such as Plctalk.com, Eng-Tips.com, and MrPLC.com. Inform the community that you are looking to build your portfolio. You’ll likely find individuals willing to offer projects and provide valuable feedback on your performance.
3.3. Starting Small: Avoiding Overwhelm
Be cautious when selecting projects. Initially, avoid those that are too complex. It’s better to be humble about your skills until you gain more experience. Taking on a project beyond your current capabilities can be discouraging.
3.4. Recognizing Your Limits: When to Step Back
How do you determine if a project is too difficult? If you struggle with basic concepts or constantly need to look up instructions, it’s a sign you need more practice with training exercises. There’s no shame in admitting you’re not ready for a particular project.
3.5. Typical Online Projects: Beginner-Friendly Tasks
Many online projects involve tasks such as adding small sections of code to a program, converting code from RSLogix 500 to PDF, or testing code. Other opportunities include building HMIs, drafting CAD drawings, or converting code between platforms (e.g., ladder logic to function block). These projects are perfect for beginners to build their portfolios.
4. No Degree? No Problem!
With a compelling portfolio showcasing your experience, the next question is whether a company will recognize your skills and the value you bring. Will they be eager to welcome you to their team and treat you as a professional?
4.1. The Skills-Based Hiring Approach
Ultimately, companies prioritize candidates who can perform the job over those with just a degree. Employers who hire inexperienced individuals take a risk, hoping the new employee can learn and is interested in programming. They also understand it will take significant time and resources to train the employee.
4.2. Skills Trumping Pedigree
It’s a harsh reality that even graduates may lack the practical skills employers need. However, the current demand for skilled professionals means that skills often outweigh formal qualifications.
4.3. Leveling the Playing Field: Self-Learning Advantages
Consider yourself on par with a college graduate, especially with the right at-home learning and portfolio development. Believing in your abilities and demonstrating your skills through tangible examples makes you a strong candidate.
4.4. Making a Strong First Impression
First impressions matter, so be prepared to showcase your skills during the interview. This proactive mindset and willingness to seize opportunities will define your future and launch your career as a PLC programmer. You could travel the world, work on cutting-edge technology, lead multi-million-dollar projects, and earn a substantial income.
5. Addressing Common Concerns: Can You Really Succeed?
The ultimate question is: Can you secure a good job if your only experience comes from learning PLC programming at home and working on small online projects?
5.1. The Answer: Yes, You Can!
The answer is a resounding YES. You can secure a great job by learning PLC programming at home and supplementing it with small online projects.
5.2. Employer Priorities: Skills Over Credentials
Employers often prioritize individuals who can do the job over those with traditional credentials. They recognize the value of practical skills and the potential for self-learners to excel.
