PLC Simulator & Automation Lab

PLCForge is a complete industrial automation lab in your pocket. Drag and drop components onto the canvas, wire them with real connections, program the
PLC with ladder logic, and watch your circuit run in real time — no hardware required.

Whether you're an automation student, an electrical technician, or an engineer, PLCForge lets you test your ideas safely and instantly.

▶ WHAT YOU CAN DO
• Place, wire, pan and zoom components on an interactive canvas
• Simulate a realistic power chain: 3~ AC supply → power supply → PLC → outputs
• Control the circuit live by tapping buttons, sensors and the E-stop
• Watch motors spin, lamps light up and contactors pull in

▶ MOTOR CONTROL CIRCUITS
Build classic control circuits the way they are wired in a real panel: contactors, overload relays, timer relays, push buttons and selector switches for DOL start-stop, seal-in, forward-reverse with electrical interlock, star-delta and sequential motor starters. Wire the control circuit and the power circuit on the same panel, run it and troubleshoot it.

▶ FULL SANDBOX PLC LADDER EDITOR
Tap the PLC and write your own ladder program:
• Contacts: NO / NC, rising & falling edge
• Coils: output, SET, RESET (latching / sealing)
• Timers: TON, TOF, TP
• Counters: CTU, CTD
• Compare (CMP) and math: ADD, SUB, MUL, DIV, MOV
• Live signal graph and input simulator

▶ RICH COMPONENT LIBRARY
PLC (CPU 1214C-style) + expansion modules (DI/DO/AI/AO) • push buttons (NO/NC) • emergency stop • selector & limit switches • contactor • thermal overload
relay • relay • 3-phase induction motor • PNP sensor • analog / temperature / pressure sensors • indicator lamps • buzzer • timer relay • DC power supply
• 3~ AC source • VFD (variable frequency drive) • servo drive • conveyor belt • pneumatic cylinder • solenoid valve

▶ FAULT SIMULATION
Inject real-world short-circuit and open-circuit faults across 27 components. The safest way to learn troubleshooting and understand how circuits behave
when things go wrong.

▶ STEP-BY-STEP GUIDED COURSE
An interactive curriculum of 24+ stops, from beginner to advanced:
Buttons → switches → emergency stop → lamps → relays → contactors → timers → counters → sensors → protection → motors → VFD → pneumatics → PLC basics →
digital I/O → ladder logic → analog I/O → compare & math → SET/RESET → capstone projects.
Every stop includes interactive demos and "Try on Canvas" circuits.

▶ CHALLENGES & READY-MADE TEMPLATES
• Challenge tasks ordered from easy to hard
• Prebuilt circuit templates: Motor Start-Stop, Sensor-Lamp, Timed Lamp, E-Stop Protected Motor, Conveyor System, Alarm Circuit, PLC Solenoid Valve,
Analog VFD Speed Control and more

▶ PROFESSIONAL TOOLS
• Save / load multiple projects
• Undo / redo
• Snap to grid
• Zoom to fit
• Wire labeling and coloring
• Build and save your own templates

▶ 14 LANGUAGES
Full support for English, Turkish, German, Spanish, Portuguese, Arabic, Indonesian, French, Italian, Polish, Czech, Vietnamese, Thai and Japanese.

▶ WHO IS IT FOR?
• Automation and electrical engineering students
• Vocational and technical school students
• Field technicians and maintenance staff
• Anyone learning PLCs from scratch
• Engineers who want to prototype ideas fast

Experiment as much as you like — no hardware to buy, no wiring risk. With PLCForge, learning automation is safe, hands-on and fun.
