PLC Ladder Simulator 1.0

PLC Ladder Simulator by K&V is an intuitive tool for designing, testing, and debugging ladder logic without the need for physical PLC hardware. Build rungs, try out control sequences, and visualize scan behavior in a safe, interactive environment that’s ideal for learning, prototyping, and teaching.

Who it’s for:

• Students and trainees learning PLC fundamentals
• Technicians and engineers prototyping control logic
• Educators demonstrating ladder logic concepts in the classroom or lab

Key features:

• Drag-and-drop ladder editor with commonly used instructions, including contacts (NO/NC), coils, latches, timers (on-delay/off-delay), counters (up/down), and edge detection
• Real-time simulation with live rung status highlighting and scan visualization
• Virtual inputs and outputs (switches, buttons, indicators) to test logic quickly
• Tag and variable management with descriptions, forcing, and watch lists for efficient debugging
• Step-by-step and continuous run modes to validate sequences and timing
• Project save and load, with options to duplicate and share project files

Use PLC Ladder Simulator to practice core concepts, verify logic before deployment, and shorten the learning curve for PLC programming. Note: This simulator is intended for education and prototyping and is not a replacement for certified industrial control systems.
