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.
