Simulate PLC logic in real-time. All in your browser. ⚡ Live Demo  •  📚 Documentation  •  Quick Start  •  Features  •  Architecture Desktop Mobile     --- ⚡ What is this? Write IEC 61131-3 Structured Text code. Watch it transform into ladder diagrams instantly. Run live simulations with scan cycle execution. Toggle inputs. Watch outputs change. Debug visually. 🎯 Features 🔄 Real-Time Transformation Write ST code and watch the ladder diagram update instantly. Full bidirectional sync keeps everything in harmony. ⏱️ Timer Function Blocks TON (On-Delay), TOF (Off-Delay), TP (Pulse) — all IEC 61131-3 compliant with proper timing behavior. 🔢 Counter Function Blocks CTU (Count Up), CTD (Count Down), CTUD (Up/Down) — complete with preset values and output flags. 📈 Edge Detection R TRIG (Rising Edge), F TRIG (Falling Edge) — single-scan pulse generation for event-driven logic. ▶️ Live Simulation Run your ladder logic with real scan cycle execution. Toggle inputs, watch outputs respond, observe timer elapsed times. 👁️ Variable Watch Panel Monitor all variables in real-time. Click to toggle BOOLs. View timers and counters. Filter by type.
