LogoSoft‑Projects
A collection of Siemens LOGO! PLC automation projects built with LOGO!Soft Comfort (v8.x). Each folder contains source files (.lsc), documentation, and simulation assets for educational or hobbyist use.
⚡ 3-time lamp switching.lld Sequentially switches three lamps ON and OFF at preset intervals. Demonstrates the usage of multiple timers in series to control independent outputs.
🔄 counter basic.lld Implements a simple counter that increments with each input pulse and triggers an output when a preset value is reached—excellent for part counting or production batch detection.
🔒 latching.lld Classic PLC “seal-in” logic: press a Start button to latch power ON, and press Stop to release. Teaches relay-like memory using self‑holding circuits.
🔁 Star-delta starter.lld Automates a three-phase motor’s Star-to-Delta transition using a timer to reduce inrush current on startup. Includes timing sequence and interlocks for safe switching.
⏱ timer ladder.lld Demonstrates a simple ON-delay timer circuit: activate input, wait preset delay, then turn output ON. Great intro to TON instructions in ladder logic.
💡 Circuit Diagram1.lsc Circuit diagram for a basic control application (e.g., lamp or motor). Visualizes inputs, outputs, interlocks, and device connections—useful for understanding how ladder logic translates to real hardware.
