Recent PLC Projects Delivered

Chemical Plant

Full automation of a bottle filling line, including PLC programming, I/O mapping, and sensor integration for line efficiency and safety interlocks.

Food Manufacturing (Melbourne’s West)

Migration from Allen Bradley SLC 5/05 to CompactLogix system, transferring over 100 I/O points while minimising downtime during commissioning.

Agricultural Processing

Custom load cell analog scaling for screw conveyor throughput control, using Micro 820 PLC with integrated touchscreen HMI.

Craft Brewery

PLC-based modification of conveyor timing logic to improve line synchronisation and reduce bottlenecks in packaging.

DISCUSS YOUR REQUIREMENTS

We understand that no two facilities are the same. Integrating automation into existing equipment often requires deeper expertise than a greenfield install—especially when managing legacy systems, varying comms protocols, or limited downtime windows. That’s where our consultative approach and hands-on commissioning experience make the difference.

Our PLC Expertise Covers:

Siemens Automation
Omron Industrial Systems
Allen Bradley (MicroLogix, CompactLogix, ControlLogix)
SCADA integration (Ignition, FactoryTalk View)
Ethernet/IP, Modbus TCP, Profibus network integration
Remote diagnostics and fault recovery
Safety PLCs and SIL-rated system design (where required)

How PLC Automation Solves Real-World Problems

Process Reliability

Custom-programmed PLC systems eliminate manual intervention, reduce downtime, and ensure consistent operation—especially in critical batch, packaging, and conveying systems.

Production Efficiency

Automation logic is tailored to optimise cycle times, reduce waste, and handle I/O-heavy systems with precision—whether you're scaling throughput or upgrading older lines.

System Integration

We connect PLCs to SCADA, HMIs, remote I/O blocks, and industrial networks—ensuring seamless data flow between equipment, operators, and supervisory platforms.

Retrofit & Uptime Solutions

Need to modernise aging PLC hardware? We design, stage, and commission PLC upgrades in a way that minimises disruption, even in 24/7 operations.

Customised Solutions Tailored to your Operations

Benefits of PLC Automation for Production & Performance

Engineered for Harsh Environments: Our PLC systems are designed to thrive in industrial conditions—from hot, wet, or dusty plants to vibration-prone equipment rooms. They’re built for continuous performance where reliability is non-negotiable.
Rapid Changeover & Flexibility: Whether you’re producing multiple SKUs or updating logic between production runs, our automation setups support fast reprogramming and line reconfiguration—without costly rewiring or downtime.
Labour & Cost Efficiency: We reduce your operational overhead by replacing manual control with logic-driven automation. Expect fewer operator interventions, lower error rates, and more streamlined shift coverage.
Energy Use & Compliance: Our PLC systems integrate seamlessly with energy metering and SCADA dashboards, enabling smarter load management, emissions tracking, and power usage reporting—helping you stay compliant and cost-efficient.

Industries that Benefit from PLC Automation Systems

Automotive & Manufacturing

PLC automation is critical in automotive and heavy manufacturing environments. We support tasks like robotic welding, component assembly, fluid mixing, and paint lines—offering seamless production shifts and minimal changeover time.

Food & Beverage

Our automation solutions help food processors streamline batch control, manage CIP cycles, and meet HACCP and food safety standards. PLCs control everything from mixing and cooking to packaging and palletising.

Pharmaceuticals

We implement PLC systems for process validation, sequencing, ingredient dosing, and quality control—ensuring compliance with Australian TGA regulations and minimising risk of cross-contamination.

Utilities & Infrastructure

From water treatment to pumping stations and lighting control, PLCs are ideal for municipal and private utility systems. We design and install systems with SCADA integration and remote monitoring for maximum uptime and visibility.

Waste & Recycling

We’ve delivered PLC automation for waste separation lines, balers, conveyor sorters, and compacting systems—improving throughput, safety, and operational efficiency in high-volume facilities.

Warehousing & Logistics

PLCs drive automation for conveyors, sorting gates, and inventory flow in warehousing and packaging centres. Our systems integrate with sensors, barcode readers, and upstream ERP software to maximise efficiency.

Frequently Asked Questions

Don’t hesitate to reach out to us today for a consultation or to schedule an appointment.

Yes. We specialise in integrating new PLC hardware and logic into legacy machines and upstream systems. Whether you’re running SCADA (like Ignition or FactoryTalk), HMIs, or other vendor-specific controls, we ensure a seamless interface and minimal downtime.

We have deep expertise in Siemens, Allen-Bradley (Rockwell), and Omron platforms. Our team selects the right platform based on performance needs, existing site hardware, and cost-effectiveness.

That depends on your facility’s scale, I/O requirements, and integration needs. For smaller standalone systems, MicroLogix or Siemens S7-1200 may be ideal. For larger networked operations, CompactLogix or Siemens S7-1500 offers more flexibility.

Yes. We regularly upgrade outdated PLC systems (e.g., SLC 500, Siemens S5) to modern platforms. We handle programming migration, re-termination, and testing—often with minimal production disruption.

Timelines vary, but typical small-to-medium projects take 2–6 weeks from design to commissioning. We provide staged work to fit production schedules and reduce impact on your operations.

Yes. We offer both scheduled maintenance and rapid-response troubleshooting for clients across Melbourne and regional Victoria.

We’re not just electricians—we’re automation engineers with hands-on experience delivering tailored, scalable PLC systems. We understand your industry and back our work with strong project discipline, safety focus, and real outcomes.
