AI-Assisted PLC Test Validation

Turn AI-Generated Test Logic Into Engineering-Approved Tests

Close the gap between project specifications, PLC logic and FAT execution.

Test Manager gives engineers a structured workspace to review, correct and approve test logic before it reaches the execution stage.

It receives drafted test logic from the Spec-to-CSV Engine, puts engineering review at the centre of the workflow, and prepares approved tests for the CSV-to-PLC execution layer.

The Problem

Why Does FAT Still Become a Last-Minute Exercise?

Functional testing often becomes difficult at the end of a project—not because the PLC cannot execute the test, but because the information required to define, review, document and prove the test is spread across multiple documents and engineering systems.

Document Fragmentation

Specifications, narratives, I/O lists and PLC logic live in different places.

Engineers spend valuable time searching documents, cross-checking information and manually transferring requirements into test sheets.

Document Drift

The design document, test case and implemented PLC logic can gradually diverge.

Without a controlled review process, changes made during engineering and commissioning can create inconsistencies that are difficult to identify later.

Manual Test Preparation

Experienced engineers spend too much time preparing repetitive test documentation.

Copying requirements from specifications into Excel-based test procedures adds effort without adding engineering value.

Evidence at Handover

Test evidence needs to tell a clear story.

At handover, project teams need to demonstrate what was tested, against which requirement, who approved it, what happened during execution and what evidence was produced.

Positioning

Test Manager Is the Engineering Control Point

The Test Manager does not replace engineering judgement.

It creates a controlled workflow around it.

AI can help extract and structure potential test logic. The Test Manager gives Subject Matter Experts a central place to review that logic, make corrections, approve the final test and prepare it for controlled execution.

Automate the preparation. Keep engineering judgement in control.

The Ecosystem

One Workflow From Specification to Test Evidence

Test Manager sits between automated test preparation and automated test execution.

It connects the three stages of the ControlSpec validation workflow:

ControlSpec workflow: Spec-to-CSV Engine produces draft test logic, Test Manager provides SME review and approval, CSV-to-PLC executes tests and produces evidence for handover
Stage 1

Specification → Structured Test Logic

The Spec-to-CSV Engine performs the upstream document-processing work and produces structured draft test information.

Stage 2

Draft Logic → Engineering Approval

Test Manager is where engineers review the proposed logic, resolve issues and approve the test definition.

Stage 3

Approved Tests → Controlled Execution

CSV-to-PLC takes approved test information into the execution workflow.

Stage 4

Execution → Evidence

Results and execution evidence can be associated with the approved test definition for project records and handover.

Core Features

A Review Layer Designed for Engineers

Feature 01

Start With Structured Logic — Not a Blank Excel Sheet

Test Manager receives structured test logic prepared by the upstream Spec-to-CSV Engine.

Instead of starting from scratch, engineers work from a proposed test definition and focus their time on checking engineering intent, identifying gaps and making corrections.

Feature 02

Put Engineering Review at the Centre

Automation does not remove the need for engineering judgement.

Test Manager gives Subject Matter Experts a controlled environment to review proposed tests, edit information, add comments and approve the final test definition.

Feature 03

Know Why Every Test Exists

Connect each test to its originating requirement, specification reference or engineering intent.

This creates a clearer relationship between:

Requirement → Test Case → Approval → Execution → Evidence

Feature 04

Know What Is Ready — and What Is Not

Replace scattered spreadsheets and email updates with a central view of test progress.

Engineers can quickly identify tests that are:

Feature 05

Move Approved Tests Into Execution

Once the SME review is complete, approved test information can be passed to the CSV-to-PLC execution layer.

The objective is simple:

No uncontrolled handoff between test preparation and test execution.

Feature 06

Build the Evidence While You Test

Capture the relationship between the approved test, its execution result and the associated evidence.

Instead of reconstructing the test history at project close-out, create a structured record throughout the validation process.

Compliance & Engineering Standards

Designed Around Structured Functional Testing

Test Manager is designed to support structured functional testing and project documentation workflows, including workflows aligned with IEC 62381 requirements where applicable.

The platform should help engineering teams maintain consistent test definitions, review records and evidence without relying on manual reformatting between disconnected documents.

Built to support structured, traceable and reviewable functional testing workflows.

How It Works

From Draft to Approved Test in Four Steps

  1. 01

    Receive structured test logic

    Test Manager receives draft test information generated by the upstream Spec-to-CSV Engine.

  2. 02

    Engineer reviews the proposed test

    The SME checks the requirement, process intent, conditions, actions and expected results.

  3. 03

    Approve or return for correction

    The test is either approved or returned with changes required.

  4. 04

    Send approved tests to execution

    Approved tests move into the CSV-to-PLC execution workflow.
