EMERGINGPROMISEREALITYACCEPTANCEPROVEN
Low-code / no-code PLC & DCS configuration is placed at the Over-Promise stage, with an estimated time to proven use of 2–5 yrs (near-term) and evidence level E3, first production use. Stage reflects attention versus results; the evidence level reflects deployment proof. The height of the curve is illustrative only. October 2026 edition.

How it works

Low-code configuration replaces written logic with assembly from tested building blocks. An engineer selects equipment modules, such as a motor, a control valve or a dosing sequence, from a library, connects them graphically and sets parameters. The tool generates the controller code, the operator faceplates and the alarms together, so they stay consistent.

In modular process plants the same idea is applied one level up. Each process module arrives with its own controller and a standard description of the services it offers, and a supervisory layer orchestrates the modules without anyone reprogramming them. Bulk engineering tools take the approach further by generating whole configurations from instrument lists and templates.

Why it matters

Could meaningfully widen the pool of people able to safely configure standard control strategies, easing the controls-engineer skills shortage.

Where it fits

It works best where the application is standard and repeated: water treatment, building and utility systems, skid packages, modular pharmaceutical and fine-chemical plants. It is less suited to unusual sequences and complex interlocks, where engineers need to see and control exactly what the logic does. Most projects end up with a mixture of generated and hand-written code.

Why we place it at the Over-Promise stage

Strong vendor push across 2025–2026; independent evidence on time-to-competency and defect rates versus traditional engineering is still limited. Estimated time to the Proven in Use stage: 2–5 yrs. What the stages mean.

Key risk

Abstracting away logic detail can hide the very edge cases that matter most in safety-adjacent control — governance of what low-code is and isn't appropriate for is still being worked out.
