Control Systems Engineering
Robust, reliable, and safe automation solutions for critical industrial infrastructure — delivered by engineers who understand the stakes.
S5 System delivers comprehensive control systems engineering services across the entire project lifecycle. Whether you are commissioning a new facility, upgrading aging infrastructure, or optimising an existing system, our engineers bring the technical depth and practical experience to deliver outstanding outcomes.
PLC & DCS Programming
Our engineers are certified and experienced across all major industrial automation platforms. We develop high-quality, well-documented control logic that is maintainable, testable, and built to last. We work with Rockwell Automation (Allen-Bradley), Siemens (S7/TIA Portal), Schneider Electric (EcoStruxure), ABB (800xA), Emerson DeltaV, and Yokogawa CENTUM.
All code is developed in accordance with IEC 61131-3 standards and undergoes rigorous Factory Acceptance Testing (FAT) prior to site deployment. We maintain detailed version control and provide comprehensive as-built documentation as a standard deliverable.
SCADA & HMI Development
We design and build intuitive, high-performance operator interfaces that enhance situational awareness and reduce operator error. Our SCADA architectures are scalable, secure, and designed for long-term maintainability. We work with leading SCADA platforms including Ignition (Inductive Automation), Citect SCADA, AVEVA System Platform (Wonderware), and Rockwell FactoryTalk View.
All HMI designs conform to the ISA-101 Human Machine Interface standard, ensuring consistent, intuitive displays that reduce cognitive load on operators in high-pressure situations.
Functional Safety Engineering
Safety is non-negotiable in industrial environments. S5 System provides comprehensive functional safety lifecycle management in accordance with IEC 61508 and IEC 61511 (AS/NZS 61511 in Australia). Our services include:
- Hazard and Operability Studies (HAZOP)
- Layer of Protection Analysis (LOPA)
- Safety Integrity Level (SIL) determination and verification
- Safety Instrumented System (SIS) design and engineering
- Proof test procedure development
- Functional safety audits and assessments
Legacy System Upgrades & Migrations
Obsolete control systems represent a significant and growing risk to operational continuity. S5 System has developed a structured, low-risk methodology for migrating aging systems to modern platforms with minimal production impact. Our approach includes comprehensive pre-migration auditing, parallel simulation testing, and phased cutover strategies designed to protect your operations throughout the transition.
