Your PLC is discontinued. Your production isn't. Migrate before it fails — not after.

Thousands of Malaysian plants still run controllers their manufacturers stopped supporting years ago. We migrate legacy control systems to modern platforms on a schedule you control — over planned shutdowns and weekends, not in the middle of a crisis.

Request an obsolescence audit

Why migrate now

The cost of waiting compounds quietly — until it doesn't.

How a legacy PLC migration works: the old PLC is audited and its program converted on a laptop, then moved to a modern PLC connected to SCADA

Spares risk — discontinued modules now come from grey-market stock at inflated prices, with no warranty.
Knowledge risk — original documentation is often missing; we reverse-engineer and re-document as part of migration.
Capability gap — legacy platforms can't support modern IIoT, energy monitoring or remote access; migration unlocks them.
Insurance & audit pressure — aging control systems are increasingly flagged in risk assessments.

Our migration approach

The old system stays intact until the new one proves itself.

Audit

Installed-base inventory, obsolescence risk rating, documentation review.

Plan

Phased design, I/O mapping, convert-vs-rewrite, downtime windows.

Convert & simulate

Program conversion and offline testing before anything touches your line.

Cutover

Planned windows with rollback plans.

Document & train

Full as-built docs and operator/technician handover.

Platforms we migrate

Proven migration paths.

Siemens S5 / S7-300 / S7-400 → S7-1500 with TIA Portal
Legacy Modicon / Telemecanique → Schneider EcoStruxure (Alliance Partner expertise)
Allen-Bradley PLC-5 / SLC 500 → ControlLogix / CompactLogix
Proprietary or undocumented systems → assessed case by case
