Software-Defined PLC Code Generator with AI SDK and Vercel AI Gateway

Translating operational logic into IEC 61131-3 Structured Text requires domain expertise and slows commissioning. Develop a software-driven automation generator using Vercel AI Gateway and the AI SDK to produce validated PLC code from plain text specifications. Reduce syntax errors to under 2% and streamline simulation validation.

What you are building

Build a web-connected software-defined automation generator with the Vercel AI SDK and AI Gateway to write and validate IEC 61131-3 Structured Text.

How work is evaluated

Evaluation

Test generated Structured Text PLC code against an IEC 61131-3 syntax parser and functional state transition tests.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

syntax_validity

Code contains no syntax or missing keyword errors

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

error_rate

Percentage of invalid ST constructs • target: 0.02 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Configure Vercel AI SDK with Vercel AI Gateway for robust LLM routing

  • Implement prompt templates for standard IEC 61131-3 Structured Text generation

  • Build automated syntax validation harnesses for PLC logic execution

  • Deploy interactive streaming interface for control engineers
