About

Built by people who run plants, for people who run plants.

Consystence Pty Ltd is the platform. It’s built by Deftec — a 64-person industrial automation business with 20+ years delivering control systems to Tier-1 Australian miners — on code that already runs plants, not whiteboard speculation.

The story

Production code, not whiteboard speculation

The device library didn’t start on a whiteboard. It started as Deftec’s production codebase — 112 UDTs and 57 AOIs lifted from real PLC code that already runs plants. Every faceplate, alarm, command, and simulation profile traces back to equipment a foreman would recognise: pumps, conveyors, crushers, screens, MCC sections.

Deftec has spent 20+ years delivering control systems to Tier-1 Australian miners. Consystence is what we wanted on every site — one platform from the PLC to the cloud, standing on code that’s already proven in the field rather than written for a pitch.

Consystence is software. The skids, panels, and field commissioning stay withDeftecand its partners. A dam pump station was the first proving ground for the full PLC → edge → site → cloud chain.

Garry holds dual engineering degrees — software and electrical — and has spent 20+ years in industrial automation, delivering control systems to Tier-1 Australian miners through Deftec.

Consystence is the platform he wanted on every site: one system from the PLC to the cloud, built on the device library Deftec already ships. He writes the C# and the IEC 61131-3 Structured Text — the platform is shaped by someone who has stood at the MCC, not just at the keyboard.

One real engineer, one real codebase — no invented team, no borrowed logos.

What we believe

Five principles, no slogans

The line on AI is non-negotiable, and the line between software and steel keeps us honest.

Precise over fluffy

We make claims a foreman can check — real equipment, real units like kPa, kW and m³/h, and standards such as ISA 5.1 and IEC 61511. If we can’t defend it, we don’t say it.

Built for the floor

Designed with ops engineers and electrical foremen, not for a slide. The interface speaks tags, alarms, and commands — the language of the people actually running the plant.

AI advises; the PLC controls

AI explains what the PLC is doing — anomalies, likely causes, what to check. It never takes control. Hard interlocks stay in IO modules and safety relays, consistent with IEC 61511 and ISO 13849.

Australian-built, data stays here

Built in Australia for Australian sites. Customer data lives in Azure Australia East, and AI inference runs onshore in Australian regions.

Software, not skids

Consystence is software. Hardware, panels, and field commissioning stay with Deftec and its partners — clean lines, software margins, and everyone doing what they do best.

Deftec’s production assets — the foundation the platform stands on.
