Tlamatini PLC

A real PLC scan in your pocket.

Tlamatini PLC runs an Allen-Bradley-style scan on your phone. Rungs solve top to bottom, timers run on the clock, and the faults are the kind a real tech gets called for. Build ladder logic, run it and practice troubleshooting, all offline.

Coming to Google Play first. iPhone follows.

Start/stop seal-in rung Ladder rung: STOP contact in series with START, with a MOTOR seal-in contact in parallel with START, driving the MOTOR coil. Energized parts are highlighted green. STOP I:0/0 START I:0/1 MOTOR O:0/0 MOTOR O:0/0
Motor stopped

Hold Start, let go, then press Stop. The motor keeps running after you release Start because its own contact seals the rung in. It's the first circuit on every print, running on the same scan as the app.

Five tools, one engine

Simulate
Free
17 classic circuits running live: seal-ins, timers, a flasher, interlocks, counters, the Logix course prints and an analog tank with hysteresis. Flip inputs and watch the power flow.
Build
With unlock
A full touch editor with 50 devices, 30 rungs and nested branches like the real prints. XIC/XIO, compare boxes, OTE/OTL/OTU, TON/TOF/RTO, CTU/CTD, RES and MOV. Undo, autosave, PDF export.
Troubleshoot
2 calls free
A machine with a hidden field fault and everything a real tech gets: the complaint, the panel, the machine and the ladder online. The logic is healthy. The field is lying. Eight trouble calls in all.
Learn
First lab free
Guided labs that run on the live engine. Read a step, try it on the circuit, then prove it on the quiz.
Scaling
Free
4–20 mA or 0–10 V to raw counts to engineering units, with the slope and offset your SCP block wants.

Help us launch on Google Play

Google asks new developers to run a closed test with real people for 14 days before an app goes public. If you work with PLCs or you're learning them, send us the email on your Google Play account and we'll add you to the test.
