Audit, plan and execute the modernisation of legacy PLC, SCADA, drives and networks — before unsupported software, vanishing spares and drifting safety standards turn into unplanned outage.
Most Australian process plants are running a control system that has already passed the vendor's stated end-of-life on at least one major component. PLC-5, SLC-500, S5 and S7-300, Modicon Quantum, InTouch 10, Vision-based Ignition projects, DH+ and Profibus networks — all still doing the job, all increasingly hard to support. The risk creeps up quietly: a control board fails, a spare costs ten times what it used to, the only engineer who remembers the logic has retired, and a cyber audit flags the flat OT network.
An honest migration is a planning problem before it is an engineering problem. ElcoTech leads with the audit and the roadmap so plant managers can sequence the work against shutdown windows and CapEx cycles — then executes the migration with proven cut-over discipline. Our engineers bring direct experience planning and executing PLC, SCADA and network migrations on major mining, water, power and process projects across Western Australia.
Six deliverables that turn an ageing control system into a sequenced, costed plan.
A full register of every PLC, HMI, SCADA server, drive and network device, tagged with the vendor's current lifecycle status — active, mature, end-of-sale, end-of-support.
What is still buyable new, what is grey-market only, what your storeroom is propping up. The honest version, not the salesperson's.
Drift against AS/NZS standards, IEC 62443 gaps, Essential Eight alignment on legacy OT networks — flagged with severity, not just listed.
Risk × cost × downtime impact, scored and ranked. So the next conversation is about sequence, not whether to start.
Sequenced execution plan with hold-points, shutdown windows, parallel-running strategy and rollback positions agreed before a tag is moved.
Multi-year budget shape with honest scope contingency — useful enough for board approval, not just for an engineer's spreadsheet.
Migration work that earns its keep preserves the operational knowledge embedded in the old system — tag names, alarm philosophy, sequence conventions, the workarounds that exist for a reason — while bringing the platform onto something supportable. ElcoTech is vendor-neutral by choice. The right migration path is the one that fits your installed base, your maintenance team, and your shutdown calendar — not the one a single vendor's account manager prefers.
Our engineers bring direct experience from major mining, water, power and process projects across WA — including brownfield PLC and SCADA migrations on iron ore handling, substation automation, lithium processing and water treatment sites. That track record shapes how we plan cut-overs: with rollback plans and witness points, not optimism.
PLC-5 / SLC-500 to ControlLogix, S5 / S7-300 to S7-1500 on TIA Portal, Modicon Quantum to M580, Mitsubishi Q to iQ-R — with logic re-structured to current standards, not just translated.
Wonderware InTouch and AVEVA upgrades, Ignition Vision to Perspective conversions, WinCC Classic to WinCC Unified, FactoryTalk View SE migrations — with tag history preserved.
Older PowerFlex, Micromaster and Altivar generations onto current platforms, with parameter sets recovered and re-tuned rather than guessed.
DH+ and Remote I/O to EtherNet/IP, Profibus DP to Profinet, serial Modbus to Modbus TCP, flat OT to Purdue-aligned segmented architectures.
Panel rebuilds, marshalling rationalisation, RIO rack swaps and switchgear refresh, tied into the wider migration so the shutdown window is used once, not three times.
Tag database recovery, P&ID re-mark-up, network diagrams, FAT and SAT packs — because most legacy systems arrive under-documented and the migration is the last chance to fix it.
ElcoTech plans and executes obsolescence and migration projects for mining and minerals processing, power and energy, water and wastewater, infrastructure, manufacturing and commercial buildings across Perth, the Pilbara, the Wheatbelt and the South West. Each sector carries its own lifecycle conventions — shutdown calendars, regulatory drivers, change-management norms — and we plan to yours, not ours.
Tell us what is ageing on your site — the platforms, the constraints, the shutdown windows. We will help you scope an obsolescence audit and a sequenced migration plan that fits.
