Use AI to explain programs you didn't write: tag tables, ladder rungs, Structured Text and Instruction List. Trace a signal from the field to the output on any platform.

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.

FBD for analog and logic, Structured Text for state machines and recipes, IL for legacy code, SFC for sequences, on any platform. 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.
