Code generation for TIA Portal

TIA Openness code generation

SCL import & export · AI generation · V15–V21 · Compile before deploy — and more
AI authors SCL blocks, the TIA Portal Openness API imports them, Studio compiles before rollout — programmatic instead of clicking block by block.

Code generation over TIA Openness

01

AI-generated SCL

Describe the logic — the AI assistant produces SCL blocks with full project context, on confirmation.
  • Project-wide context
  • FB / FC / DB / UDT
  • Editable in chat
02

Openness import

Generated blocks land straight in the TIA project via the Siemens Openness API — no manual copying.
  • Openness API V15–V21
  • Import & export
  • Programmatic
03

Compile before deploy

Studio compiles generated code against the real project before anything reaches the PLC.
  • Early error detection
  • No blind deploy
  • Against real interface
04

Bulk export/import

Export, generate, re-import and diff whole block groups while keeping the folder structure.
  • Folder structure kept
  • Diff after import
  • Mass operations
05

Typicals & reuse

With Forge, capture reusable block types and deploy the whole library into a PLC.
  • Block type library
  • From any project
  • Deploy to PLC
06

Verified by unit tests

Test generated code straight against PLCSIM Advanced or a real PLC — generate and prove in one flow.
  • SCL unit tests
  • PLCSIM & real PLC
  • CI/CD-ready

Code generation with TIA Openness — guide

TIA Openness is Siemens' official programming interface (API) for TIA Portal. Through it, projects, blocks and configurations can be read, written, exported and imported programmatically — the basis for generating SCL code instead of creating every block by hand in TIA Portal.

How does code generation work?

AnyAutomation Studio combines AI with the Openness API into one end-to-end flow: the AI assistant produces SCL blocks (FB, FC, DB, UDT) with full project context, the Openness API imports them straight into the TIA project, and Studio compiles the result against the real project before anything is rolled out. Repetitive, schematic code — typicals, standard blocks, interfaces — comes together in a fraction of the time.

Generate, import, verify

Generated code is only useful once it provably works. So the loop closes: AI generates → Openness imports → SCL unit tests verify against PLCSIM Advanced or real hardware → Git and CI/CD track every change. More on the AI in AI integration, more on Openness in the introduction.

Frequently asked questions

What is TIA Openness?

TIA Openness is Siemens' official API for TIA Portal. It lets you read, write, export and import projects and blocks programmatically — instead of doing everything manually in the TIA Portal UI.

Can AI generate SCL code for TIA Portal?

Yes. The AI assistant in AnyAutomation Studio generates SCL blocks with full project context on confirmation and imports them into the project via the Openness API. The code is compiled before deploy.

Which TIA Portal versions are supported?

Openness automation runs with TIA Portal V15 to V21 on Windows 10/11 (64-bit).

Is generated code compiled before rollout?

Yes. Studio compiles generated code against the real project before it reaches a PLC — errors surface early, not on the controller.

How does code generation relate to unit tests?

Generated blocks can be verified straight away with SCL unit tests against PLCSIM Advanced or real hardware — generate and prove in one continuous workflow.
