Free PLC Programming Courses for Electrician Skills

Build job-ready automation skills with this selection of free online PLC programming courses designed for anyone pursuing or expanding electrician competencies. Programmable Logic Controllers (PLCs) are at the core of modern industrial control, powering everything from motor starters and conveyors to pump stations, safety interlocks, and process automation. These courses focus on practical, industry-relevant knowledge so you can understand how control panels, sensors, actuators, and industrial networks come together in real-world systems.

Whether you are starting from basic relay logic concepts or moving toward advanced troubleshooting, these free PLC courses help you learn how to read and create control logic, interpret I/O wiring, and work confidently with common PLC workflows. You will explore essential topics such as digital and analog signals, addressing, scan cycle behavior, timers and counters, latching, sequencing, and safe commissioning practices. For electrician-focused learners, PLC programming is a high-value skill that improves your ability to install, test, and maintain automated equipment while communicating effectively with maintenance and controls teams.

Courses included

• PLC Training Series Step – A structured set of lessons that introduces PLC fundamentals and builds toward hands-on logic development. Expect clear progression through core concepts like inputs/outputs, ladder logic patterns, timers/counters, and troubleshooting techniques that translate well to plant-floor tasks.
• Siemens PLC Training – A course pathway oriented around Siemens PLC environments, ideal for learning common industrial practices and terminology used in Siemens-based automation. Topics typically include program organization, addressing, diagnostics, and best practices for developing and testing logic.

What you can learn in these free PLC programming courses

• How PLCs control machines using the scan cycle, logic evaluation, and output updates
• How to design and interpret ladder logic for common electrician scenarios (start/stop circuits, interlocks, permissives)
• Use of timers, counters, comparators, and memory bits for sequencing and batching
• Basics of I/O mapping and how field wiring relates to software addresses
• Troubleshooting methods: reading status, forcing safely, fault isolation, and verifying signals
• Introduction to commissioning workflows, documentation, and change control habits

Who these courses are for

These free online PLC programming courses are well-suited for electricians, maintenance technicians, and automation beginners who want to strengthen control-system literacy. They also support experienced electrical workers who need a practical refresher on industrial logic and diagnostics to reduce downtime and improve safety.

Why learn PLC programming as an electrician

PLC skills help you move beyond wiring and installation into higher-value tasks like diagnosing intermittent faults, validating sensor feedback, confirming interlocks, and collaborating on equipment upgrades. By completing these free courses, you can develop a foundation that supports more advanced topics such as HMI integration, industrial networking, and structured troubleshooting across complex systems.
