Tlamatini

The line is down. Here's the contact that stopped it.

Open the PLC program on your phone, mark the inputs you see lit on the I/O card, and Tlamatini follows the logic back from the output that won't turn on to the device you need to check.

Try it below with a sample conveyor program. Tap a contact to change an input; tap a coil to ask why it's off.

How it works

  1. 1Export the program. In Studio 5000, File → Save As → .L5X. Anyone with the software can do it once and send you the file.
  2. 2Mark what you see. Which inputs are lit on the card: the stop, the guard switch, the photo-eye.
  3. 3Ask why. Pick the output that won't turn on. Tlamatini shows the rung, the contact that blocks it, and why — rung after rung, down to the device.

Your program stays on your device

The file is read inside your browser. It is never uploaded, and Tlamatini never connects to a PLC: it reads and simulates, nothing else.

The answer comes from the ladder logic itself, evaluated the way the controller does — not from a guess. When the program uses an instruction this prototype doesn't evaluate yet, it says so.

Prototype: Allen-Bradley Logix ladder (.L5X). Evaluates XIC, XIO, OTE, OTL, OTU, ONS, OSR, OSF, TON, TOF, RTO, CTU, CTD, RES, EQU, NEQ, GRT, GEQ, LES, LEQ, LIM, MOV, CLR, ADD, SUB, MUL, DIV, CPT, ABS, JSR, JMP/LBL, RET, TND and MCR.

Get the app when it's ready

We're deciding what to build next with the people who'd use it. Leave your email and we'll write when there's something new to try.

Your email is used only to write about Tlamatini. Reply to any of those emails and we'll delete it.

Describe it, get the ladder

Write what the machine should do and in what order — “start the conveyor when the guard is closed, stop it after 10 boxes” — and get the rungs written for you, tested in the simulator before you see them.

Not built yet. If you'd use it, tell us and we'll build it sooner.
