Legacy machines
Mechanically sound machines with dead controls.

The machine is fine. It's the 20-year-old controller you can't buy spares for that's the problem.
Replace obsolete controls without replacing the whole machine.

Obsolescence assessmentLike-for-like upgradeMinimal downtime swapDocumented as-built
Plenty of perfectly good machines get scrapped because their controller went obsolete and nobody could support it. That's an expensive way to solve a cheap problem.
We assess what's obsolete, design a drop-in modern replacement — often Servonix hardware with documented logic — and plan the swap around your shutdown window so the line is down for the minimum time.
You keep the mechanical machine you know, and gain controls you can actually support for the next decade.

Stage by stage
What we actually do
01
Assess
We identify what's obsolete and unsupportable, and what can stay.
02
Design
A drop-in modern control package — hardware, logic and panel — engineered to the existing machine.
03
Pre-build
Panels built and programs written and simulated before the shutdown.
04
Swap
Executed in your shutdown window, commissioned, and fully documented as-built.
Configurations
Capability at a glance
Targets
PLC, drive, HMI, panel
Any obsolete control element, or the whole control system.
Downtime
Planned
Pre-built and simulated to fit your shutdown window.
Result
Supportable
Modern hardware with a decade of spares ahead of it.
