truST — open IEC 61131-3 control workspace

Documentation: https://johannespettersson80.github.io/trust-platform/

truST is an open IEC 61131-3 control workspace: one project edited in VS Code, run by trust-runtime, observed through browser HMI, automated through CLI and Agent APIs, connected through truST Mesh, and assisted by AI tools that can read diagnostics and use typed truST surfaces.

Runs on Linux, including PREEMPT_RT soft-real-time deployments, macOS, Windows, and Raspberry Pi.

The same runtime also serves a browser IDE at /ide and an operator HMI at /hmi, so one project drives engineering, automation, and operation without separate project copies to reconcile.

Read One Project, Every Surface for the surface map and AI/tooling boundaries. Runtimes connect to each other and to plant systems through truST Mesh: one runtime, the right wire for each job.

Start

• Install truST
• Choose your workflow
• Program in VS Code
• Use AI assistance
• Operate in Browser HMI
• Migrate existing PLC work

Features

• IEC-aware diagnostics, formatting, rename, navigation, and refactors
• Editor AI tools for typed diagnostics, navigation, file edits, HMI work, telemetry, settings, and debug actions
• Runtime panel with live values, memory, and I/O inspection
• Debugger with breakpoints, stepping, locals, and call stack
• Browser IDE and operator HMI backed by the same project/runtime
• CLI, Agent API, deterministic test, and harness workflows
• truST Mesh for runtime-to-runtime and plant connectivity
• PLCopen XML import/export and visual editor support
