Automation Panel Applications with Siemens S7-1200 PLC Course

Editorial Take

Automation is the backbone of modern manufacturing, and this course offers a rare hands-on entry point for beginners. Tolga TOLAN delivers a structured, practical curriculum focused on building real automation panels using the Siemens S7-1200 PLC. With a strong emphasis on wiring, component integration, and motor control, it bridges the gap between theory and shop-floor application.

Standout Strengths

• Hands-On Wiring Focus: The course excels in teaching physical PLC wiring and component layout. Learners gain confidence in assembling real automation panels from scratch.
• Motor Control Clarity: Direct and interlocked motor starting circuits are explained with precision. The step-by-step demonstrations make complex control logic easy to follow.
• Real Component Integration: Students learn to connect actual circuit components used in industrial panels. This practical knowledge is invaluable for field technicians and engineers.
• Timer Application Depth: The module on TP, TON, TOF, and TONR timers is exceptionally detailed. It covers timed motor stopping and periodic operation with real-world relevance.
• PNP and NPN Connector Mastery: The distinction between PNP and NPN sensor wiring is clearly explained. This foundational knowledge prevents common field errors in PLC installations.
• Beginner-Friendly Structure: The course is logically sequenced, starting with materials and progressing to full system operation. Each module builds on the last without overwhelming the learner.

Honest Limitations

• Limited Advanced Content: The course stops at basic timer applications. It does not cover advanced programming, HMI integration, or network communication protocols like Profinet.
• Hardware Dependency: Learners need access to physical components like PLCs, motors, and relays. This limits accessibility for those without lab access or training kits.
• Safety Standards Omission: While wiring is taught, there is minimal discussion on electrical safety, grounding, or compliance with IEC or NEC standards—critical in real installations.
• No Simulation Tools: The course does not include PLC simulation software practice. This could hinder learners who cannot immediately access hardware for experimentation.

How to Get the Most Out of It

• Study cadence: Follow a 2-week module plan with hands-on replication. This ensures retention and practical mastery of each wiring technique.
• Parallel project: Build a mini control panel alongside the course. Use a Siemens S7-1200 starter kit to replicate circuits in real life.
• Note-taking: Sketch every circuit diagram manually. This reinforces understanding of component interconnections and control logic flow.
• Community: Join Siemens automation forums and share your panel builds. Feedback from professionals enhances learning beyond the course.
• Practice: Repeat each motor control exercise three times—once following, once from memory, once modified. This builds true proficiency.
• Consistency: Dedicate 45 minutes daily to theory and 30 minutes to hands-on work. Regular engagement beats marathon sessions for skill retention.

Supplementary Resources

• Book: 'Programmable Logic Controllers' by Frank Petruzella. This textbook complements the course with deeper theory on PLC architecture and ladder logic.
• Tool: TIA Portal software (Siemens). Use the free trial to simulate logic before wiring, enhancing safety and understanding.
• Follow-up: Take a course on SCADA systems next. This builds on PLC knowledge to monitor and control entire processes.
• Reference: Siemens S7-1200 System Manual. Download the official PDF for detailed specifications and wiring diagrams.

Common Pitfalls

• Pitfall: Skipping safety grounding in practice builds. Always include grounding in your panel design to avoid equipment damage and personal risk.
• Pitfall: Confusing PNP and NPN inputs. Double-check sensor types before wiring to prevent PLC input damage or logic errors.
• Pitfall: Overlooking wire gauge selection. Using undersized wires can lead to overheating—always match wire size to motor load and distance.

Time & Money ROI

Time: The course requires 8–10 hours of focused learning. For career switchers, this investment yields immediate hands-on skills for entry-level automation roles.
• Cost-to-value: While paid, the course offers high value for the depth of practical content. Comparable lab training costs significantly more.
• Certificate: The completion certificate adds credibility to resumes, especially for technical job applications in manufacturing or maintenance.
• Alternative: Free YouTube tutorials lack structure and depth. This course’s organized, progressive approach justifies the price for serious learners.

Editorial Verdict

This course stands out in the crowded PLC training space by focusing on what most courses ignore: physical panel construction and real wiring. While many PLC courses stop at ladder logic, Tolga TOLAN goes further, teaching learners how to build the entire control system from the ground up. The emphasis on motor control circuits, timer applications, and sensor wiring makes it ideal for technicians, electricians, and engineers entering industrial automation. The hands-on nature ensures that learners don’t just watch—they build, connect, and power real systems.

That said, it’s not a complete automation curriculum. Those seeking advanced topics like HMI design, SCADA integration, or networked PLCs will need to look elsewhere. However, as a foundational course, it excels. The lack of safety protocol coverage is a concern, but this can be supplemented with external resources. For beginners with access to basic hardware, this course delivers exceptional value. It transforms theoretical knowledge into tangible skills, making it a strong recommendation for anyone serious about a career in automation. Pair it with simulation software and real-world practice, and it becomes a cornerstone of practical engineering education.
