Structured, tested and well-documented PLC code across Allen-Bradley, Siemens, Schneider, Beckhoff and CODESYS — built around the way your process actually works.
Your control system is the heartbeat of the operation. The logic behind it needs to be reliable, clear and easy to support — long after commissioning. ElcoTech is a vendor-neutral PLC programming and integration partner, working across every major platform used in Australian industry.
From small machine control to large process plants, safety-rated shutdown systems and remote telemetry RTUs, we deliver code that is structured, tested, version-controlled and documented in a way your maintenance team can actually pick up and extend.
Deep working knowledge across the major PLC families — and the dev environments that go with them.
ControlLogix, CompactLogix, MicroLogix and PLC-5 / SLC-500 legacy. Studio 5000 Logix Designer, RSLogix 5000 and FactoryTalk.
S7-1500, S7-1200, S7-400 and S7-300 across TIA Portal and STEP 7 / Classic, including Safety Integrated and PROFINET architectures.
Modicon M580, M340 and Quantum on EcoStruxure Control Expert (Unity Pro), plus Magelis HMI and Modbus TCP integration.
TwinCAT 3 PLC and motion runtime on Beckhoff Industrial PCs and EtherCAT I/O for high-performance machine control.
WAGO, Phoenix Contact PLCnext, Revolution Pi and other CODESYS V3 platforms — useful for edge, OEM and cost-sensitive applications.
ABB AC500, Omron NX / NJ, and Emerson DeltaV / RX3i — supported where your installed base or process demands them.
PLC work goes well beyond writing ladder. Our scope covers the functional specification, code structure, library and UDT design, alarm logic, sequence design, FAT, site commissioning and as-built documentation — built in the IEC 61131-3 languages best suited to the task. Structured text for math and parsing, function block for instrument and motor objects, ladder for interlocks and machine logic that maintenance staff can read at the panel.
Our engineers bring direct experience from major mining, minerals processing and power generation projects across Western Australia — PLC and SCADA delivery on iron ore handling, lithium and process plants, substation automation, and brownfield migrations on heavy industrial sites. That track record shapes how we structure code, name tags and write handover documentation: for the people who have to live with the system at 2 a.m., not just the people who built it.
Every project ships with a code structure document so the next engineer can find their way around without guessing.
Continuous control, batch sequences, interlocking and machine state-machines built against a clear functional spec.
SIL-rated safety logic for emergency shutdown, fire and gas and machine safety on Siemens F-Series, AB GuardLogix and equivalent platforms.
Remote site RTU programming, water and gas SCADA, pipeline supervisory control and DNP3 / Modbus integration.
PLC-5 to ControlLogix, S7-300 to S7-1500, Quantum to M580 and other modernisations that preserve proven logic and operator knowledge.
Structured FAT with I/O simulation, sequence walk-throughs, alarm verification and signed-off test records before the system leaves the workshop.
Loop checking, point-to-point verification, dynamic testing and structured handover to your operations and maintenance teams.
ElcoTech delivers PLC programming for mining and minerals processing, power and energy, water and wastewater, infrastructure, manufacturing, commercial buildings and agriculture across Perth, the Pilbara, the Wheatbelt and the South West. Every sector has its own conventions — naming, alarm philosophy, document deliverables — and we work to yours, not ours.
