Forty-plus lessons is a library. A path is a program. This is the trail from "what's a PLC?" to job-ready automation engineer — a single climb through five altitude bands, each resting on the one below. Follow the line down; every medallion opens its lesson and lights up once you've been there. The summit is a real engineer.
Finish the climb and you can read a P&ID and a schematic, wire a panel and reason about sinking vs sourcing, write structured logic with the right POU, scale an analog signal, tune a PID loop, size a motor, build an HMI, place MES and ERP, defend the network — and, above all, troubleshoot a dead machine methodically instead of guessing. That's not a beginner. That's an engineer.
