88 hands-on lessons across IEC 61131‑3, Allen‑Bradley, Siemens SCL, Mitsubishi, Omron, Schneider, Delta, and Instruction List. The same physical scenario — a motor, a conveyor, a tank — taught in the syntax of the PLC brand you work with.
The same physical machine — a motor start/stop, a conveyor, a tank fill — taught in the syntax your actual employer uses. Mitsubishi GX Works, Siemens TIA Portal, Allen-Bradley Studio 5000, Omron Sysmac, Delta, Keyence, Panasonic, and IEC 61131‑3.

Four things that separate learning PLC syntax here from reading a manual.
Each lesson teaches a single physical concept — a seal-in circuit, a rising-edge trigger, a TON timer — expressed in the syntax of the PLC brand you work with. Switch dialects and the machine model stays identical; only the code changes. Your mental model transfers across brands.
The simulator runs a real scan cycle in a Phaser canvas. You type code, hit run, and watch the I/O respond. No install, no virtual machine, no hardware required. What you type is what gets executed.
Lessons 1 through 6 — output coil, NC contact, AND logic, OR-stop, seal-in, SET/RESET — are free on signup. That covers the core combinational and latching patterns that underpin 80% of real-world ladder rung logic.
Pro unlocks the worked solution for every lesson across all 8 dialects. If you are stuck on lesson 9 in Omron CX-Programmer syntax, the solution is one click away. Solutions are read-only — the sandbox is still yours to experiment in.
Each lesson runs across all 8 dialects. Lessons 1–6 are free; lessons 7–12 require Hobby+ or Pro. Worked solutions for every lesson require Pro.
