FREE IO-LINK DEVELOPER TOOLS

Your assistant. Your IODD.

Create device descriptions, check parameters and process data, and export editable projects and firmware source. Connect your assistant, then use LabWired to check the supported sensor application.

No iolinki account needed. Hosted projects run on our server. Save an explicit recovery snapshot for up to 24 hours and keep its token private, or download a project for longer retention. Use local stdio when files should stay on your machine.

Prefer to run locally?

Install Node.js 22 or newer. This command downloads and starts the local stdio server. Local projects and snapshots are memory-only; export before restarting:

ChatGPT uses a hosted connection. For local files, use a supported desktop client below.

2. Ask for your first device

Create a switching-sensor IODD with my assigned vendor/device IDs and defaults. Inspect and validate it, export editable JSON/XML/ZIP, and save a recovery snapshot with its token kept private. Generate the source kit. If LabWired is connected, compile and verify the sensor application. Report schema, official Checker and execution results separately.

Open the exported project or ZIP in the browser editor to review and continue editing. Restore a saved snapshot in a new session using its private token; anyone holding the token can restore or delete it.

The 20 tools include firmware source and recovery. The sensor kit runs the released application on a modeled STM32F401 and checks thresholds, hysteresis, validity, parameters and process bytes. LabWired receives the submitted firmware source; report its actual verdict and model gaps. Physical IO-Link master, PHY and cable tests remain separate.

Give your agent the context

Stack guides, hardware references and IODD workflows in one place.

Basic model/CRC checks and validation against the pinned official October 2025 XSD package are separate results. The official IODD Checker is not configured on this hosted deployment; its official distribution is being checked separately; schema validity does not constitute official approval.
