Structured PLC, DCS and RTU code for Rockwell, Siemens, Schneider, Beckhoff, Omron, ABB and CODESYS-based systems.
We write control code that is clear, structured and practical to maintain. The goal is not just to make the system work at commissioning, but to leave behind code that can be understood and supported later.
Deep working knowledge across the major PLC families and the development environments that go with them.
ControlLogix, CompactLogix, MicroLogix and legacy PLC-5 / SLC-500 systems.
S7-1500, S7-1200, S7-400 and S7-300 on TIA Portal and STEP 7.
Modicon M580, M340 and Quantum platforms.
TwinCAT-based control and motion applications.
WAGO, Phoenix Contact PLCnext, Revolution Pi and other CODESYS V3 systems.
Supported where the site base or process requires it.
Our scope can include functional specifications, code structure, object libraries, alarm logic, sequence design, FAT, commissioning and as-built documentation.
We use the IEC 61131-3 language best suited to the task and keep the structure readable for maintenance staff.
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.
We deliver PLC programming for mining, water, power, infrastructure, manufacturing, commercial and agricultural sites across Western Australia.

Running PLC-5, S5, S7-300, Modicon Quantum or Mitsubishi Q? Migration is a planning problem before it is an engineering one. See how we audit the lifecycle exposure and sequence the roadmap before touching the logic.
Tell us what you are building, migrating or repairing, and we will shape the programming approach around the site.
