About this app
Learn PLC ladder logic programming from scratch with PLC Ladder Learn — an animated, hands-on simulator built for engineering students, technicians, and anyone new to industrial automation.
No expensive software, no real hardware needed. Open the app and start building and simulating real PLC ladder diagrams right on your phone.
▶ ANIMATED LESSONS
Every concept is taught with moving visuals. Watch timers count up, contacts open and close, current flow through the rung, and circuits operate step by step. You learn ladder logic with your eyes — not dry text.
▶ LIVE LADDER SIMULATOR (SANDBOX)
Build your own ladder diagrams and run them in real time:
• Place contacts (NO/NC), coils, SET/RESET, timers and counters
• Toggle inputs and watch outputs respond instantly
• Series (AND), parallel (OR) and combined logic
• Live signal graph (oscilloscope) to trace bits and values
• Undo/redo, address suggestions and custom labels
▶ WHAT YOU'LL LEARN
• Ladder logic & ladder diagram basics
• Normally Open / Normally Closed contacts and output coils
• Addressing (I, Q, M, DB) and the PLC scan cycle
• Timers — TON, TOF, TP
• Counters — CTU, CTD
• Memory bits, latching, SET/RESET
• Positive / negative edge detection
• Comparison, MOVE and math instructions
• Analog I/O — 4-20 mA, scaling, PID basics
• FC / FB blocks and program structure
• Industrial communication — RS-485, PROFIBUS, PROFINET, Modbus
▶ REAL-WORLD SCENARIOS
Practice with examples you'll meet on the job: start/stop motor control, conveyor logic, traffic lights, pump control, elevator sequencing, sequential start and alarm handling.
▶ QUIZZES & PRACTICE
Reinforce every lesson with quizzes and guided exercises that check your ladder solution automatically. Earn XP and track your progress as you learn.
▶ WHO IS THIS FOR?
• Engineering & vocational students (electrical, mechatronics, automation)
• Technicians and maintenance staff
• Career changers moving into PLC programming
• Anyone learning Siemens S7 / TIA Portal concepts or preparing for an automation job
▶ WHY PLC LADDER LEARN
• Learn by doing — build and simulate, don't just read
• Beginner-friendly, step-by-step path
• Works fully offline, anytime
• English & Turkish supported
