From source to verified behavior

The workflow

Six connected phases, with engineering judgement throughout. Understand the sources, connect the data, apply standards, review decisions, generate outputs, and validate the results.

Traceability stays with every phase. Existing projects can enter at the stage they need.

Understand sources

Give AI the same project context your engineers use.

Bring in P&IDs, instrument lists, spreadsheets, HMI displays, existing PLC and HMI code, and controller exports. Whether a project begins with documents, code, or both, Relay Control reads the available structure so the team can work directly from the source.

Source context includes documents, code, and controller exports.

Inputs: Project documents and code
Outputs: Identified equipment and source structure

Engineer decisionConfirm source context and extraction scope.

Connect engineering data

Connect engineering data without losing the evidence.

AI helps identify the same equipment, tag, value, or control concept across documents and existing code. Every proposed match carries the cell, table, page region, tag, routine, or code reference that produced it.

Every proposed connection retains its source evidence.

Inputs: Source references
Outputs: Proposed links with evidence

Engineer decisionInspect ambiguous relationships.

Apply engineering standards

Apply your team’s approved engineering standards.

Select approved modules, existing code patterns, and templates that fit the project. Signed Connectors are bound to an exact version, so the team can review which engineering assets and operations it is using.

Inputs: Linked data and approved assets
Outputs: Module selection and configuration

Engineer decisionConfirm applicability and versions.

Review and approve

Turn proposals into engineering decisions.

Inspect the proposed connections and configuration alongside the selected modules and source evidence. Engineers approve, reject, or request a correction. Conflicts stay visible until they are resolved.

Pending, approved, and conflicting items remain distinct.

Inputs: Proposals and configurations
Outputs: Accepted decisions and unresolved issues

Engineer decisionApprove, reject, or request correction.

Generate outputs

Generate consistent outputs with their sources attached.

Create vendor artifacts for Studio 5000 and TIA Portal from approved project data and reusable code. Keep generated values connected to their source locations, so engineers can inspect what changed and why.

Generated values retain their source references.

Inputs: Approved configuration
Outputs: Generated artifacts and source references

Engineer decisionInspect generated changes.

Test and validate

Check behavior against the requirements.

Define checks from engineering requirements, run them against supported simulator setups, and compare expected behavior with observed results. Review failures, cleanup status, and source evidence before accepting the outputs.

Assertion results and cleanup evidence are reviewed separately.

Inputs: Test definitions and prepared simulator
Outputs: Results, diagnostics, and cleanup evidence

Engineer decisionResolve failures and accept results.
