LadderSimLab vs PLC Ladder Logic Simulator

PLC Ladder Logic, made visual. LadderSimLab is a complete, hands-on learning environment for understanding PLC programming and industrial automation. Build ladder circuits, run them through a live PLC scan engine, interact with virtual inputs and watch every output respond in real time. Whether you are learning from zero, studying automation, preparing for technical work or refreshing your PLC knowledge, LadderSimLab turns abstract logic into something you can see, control and understand. LEARN BY BUILDING Your first launch begins with a guided project. The app highlights the correct control at every step and helps you build a working ladder circuit without getting lost. Continue learning with: • 12 focused PLC lessons • 15 automated programming challenges • A 10-part illustrated visual guide • Editable example circuits • Clear explanations of contacts, coils, timers, counters, memory and safety logic BUILD AND SIMULATE Create your own PLC projects using a visual Ladder Logic editor. • Add and arrange ladder rungs • Use normally open and normally closed contacts • Add output, set and reset coils • Work with TON timers and CTU counters • Build parallel branches • Use comparisons, edge detection and memory instructions • Run, pause, reset or advance the PLC one scan at a time • Monitor scan count and execution time • Control virtual inputs and observe outputs instantly • Save and reopen your projects LIVE MACHINE LABS Go beyond individual circuits and see how PLC logic controls complete physical processes. Explore six interactive machine labs: • Conveyor Cell • Water Tank • Bottle Filling • Traffic Intersection • Industrial Motor • Two-Floor Elevator Sensors automatically feed the PLC while outputs drive animated actuators. Watch packages move, tanks fill, bottles process, traffic lights change, motors run and elevators travel between floors. PRACTICE WITH REAL CHALLENGES Open a challenge, build your solution and let the app test it automatically. Progress from direct outputs and contact logic to motor seal-in circuits, emergency-stop systems, timers, counters and interlocks. Challenges provide a safe place to experiment, identify mistakes and improve your logic without requiring physical PLC hardware. DESIGNED FOR CLARITY LadderSimLab uses a modern visual interface with live power-flow highlighting, clear hardware mapping and readable PLC symbols. Active circuits glow as the scan engine evaluates them, making it easier to understand why an output is ON or OFF. IDEAL FOR • Industrial automation students • Electrical and electronics students • PLC beginners • Technicians and engineers • Instructors and training environments • Makers and automation enthusiasts FULLY OFFLINE Lessons, guides, challenges, projects, examples and machine simulations work offline. The complete learning experience is included with no subscriptions or locked modules. Learn the logic. Build the circuit. Watch the machine respond. LadderSimLab is an independent educational simulator. It is not affiliated with any PLC manufacturer and is not intended to replace certified industrial engineering tools or safety systems.

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 iPhone or iPad. 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 50 REAL-WORLD PROBLEMS Solve graded automation problems from easy to hard: motor start/stop, burglar alarm, automatic door, conveyor control, mixing reactor, star-delta starter, paint booth airlock and many more. Your ladder solution is checked automatically, and selected problems show the real process animated live while your program runs.
