Use AI to explain programs you didn't write: tag tables, ladder rungs, SCL and STL. Learn to trace a signal from the field to the output and spot what the code really does.

Have AI draft ladder logic, then review it like a pro: seal-ins, timers, counters, compares and interlocks. Import it, run it in simulation and fix what's wrong.

The other four Siemens languages: FBD for analog and logic, SCL for state machines and recipes, STL for legacy code, S7-GRAPH for sequences. When to use each, and how AI handles them.

Scale 4-20 mA and raw counts into engineering units, detect wire breaks, and tune a PID loop on a simulated tank.

Write a test plan, force faults, and prove your program does what the spec says before it ever sees a real machine. A small version of a factory acceptance test.

A repeatable fault-finding method: symptoms, evidence, the program, the field. Use AI to narrow it down fast without guessing.

Build a simple operator screen, wire alarms, and get read-only machine data into a dashboard (MQTT, database, Grafana).

Turn electrical drawings into an I/O list and a program skeleton with AI help, and check a program against the drawings.

Put it all together: spec, program, HMI, test plan and commissioning report for a simulated line. Get feedback from the community.

71 copy-ready prompts for real PLC work: read and explain code, write LAD/SCL/STL/FBD/GRAPH, review AI output, analog and PID, test plans and FAT, troubleshooting, HMI and alarms, plant data, drawings and I/O lists, commissioning. Each card says what to attach and how to check the answer.

Download the real files behind the courses: the demo line PLC program and HMI, the read-only data stack (collector, MQTT, TimescaleDB, Grafana), Excel templates for FAT records, fault logs, I/O lists and alarm rationalization, and every Siemens reference solution compile-checked in TIA Portal V15.1.
