Industrial tools that run in your browser.

OpenPLC Web Studio

Write ladder logic, Structured Text, IL, FBD or SFC and run it on a PLC engine written in Rust and compiled to WebAssembly. Thirteen guided labs check your program against each lab's steps.

• Learn layout for beginners, Pro layout with every tool
• The I/O bench presses real inputs on the running program

AASX Voyager

Open an Asset Administration Shell package (.aasx) in the browser: browse submodels, read the digital nameplate and export JSON or CSV. The parser is Rust compiled to WebAssembly, so your files stay on your machine.

• Ships with a sample actuator package to try

AASX viewer component

The viewer as one custom element you can drop into an Angular or React app (npm package aasx-viewer). The page shows it with three sample packages.

3D heat city

1.39 million building footprints with estimated heights, Sentinel-2 imagery, terrain and today's IMD station readings. A surface heat model sits on top, checked against Landsat land-surface temperature.

• Lighting follows the real sun position for the chosen hour
• The heat layer is a model, and the page shows its error against Landsat

Road twin

The OpenStreetMap road network with structural chokepoint scores, a data-quality layer and Bengaluru Traffic Police signal timings, plus an open review of where each timed junction really is.

• No traffic simulation: open data has no vehicle counts

Ridgeview booster station

A water booster station with two copies of one PLC program, compiled to WebAssembly, running as primary and standby. The pump, tank, pipes, field network and instruments are simulated in the page.

• Press START on the pump faceplate to run it

Duplicate-order test

What happens when a lost acknowledgement makes an MES send the same dosing order twice, with and without an idempotent function block (FB_TxnGuard) on the PLC.

• FB_TxnGuard compiles with IronPLC and MATIEC (re-run 25 Oct 2026)
• The two machines on the page are a JavaScript model of it

Virtual PLC landscape

Thirteen virtual and software PLC runtimes compared on architecture, safety rating and protocols.

• Compiled from vendor documentation; only OpenPLC has been run here

Ornith PLC code model

A 9-billion-parameter model fine-tuned on PLC code, published as a LoRA adapter on Hugging Face, with a browser editor that checks Structured Text.

• The editor's checker is a JavaScript approximation, not IronPLC
• The benchmark scores have not been reproduced from saved results
