Programmable Logic Controllers (PLCs)
Reliable, scalable PLC solutions that simplify automation and enhance control across industrial environments.
Engineered for Seamless Integration
CSE W Arthur Fisher specialises in delivering Modicon PLC solutions from Schneider Electric, enabling industrial operators to take control of complex processes, improve productivity, and reduce downtime.
With one of the most established Modicon install bases in New Zealand, CSE W. Arthur Fisher has built a reputation for delivering reliable, high-performance automation systems across utilities, infrastructure, and industrial sectors.
Backed by Industry Experience
Our capability is underpinned by deep in-house expertise, having been directly involved since the early adoption of PLC technology in the market. This depth of experience ensures that we not only understand modern automation systems, but also the legacy platforms still widely deployed across New Zealand.
As a long-standing and trusted system integrator for Schneider Electric, we continue to support, upgrade and expand Modicon-based systems across a wide range of applications.
Industry Applications
Manufacturing and Assembly Lines
PLCs play a critical role in coordinating automated machinery, conveyor systems and quality control stations. They enable precise timing and synchronisation across production stages, helping manufacturers reduce waste, improve throughput and maintain consistent product quality. Advanced PLCs also support predictive maintenance and integration with MES systems for real-time production insights.
Water and Wastewater Treatment
In municipal and industrial treatment facilities, PLCs manage complex sequences involving pumps, valves, chemical dosing and filtration. Their ability to interface with sensors and SCADA platforms ensures accurate process control, regulatory compliance and efficient resource use. Redundancy and fail-safe features are essential for maintaining uptime in critical infrastructure.
Mining and Materials Handling
Mining operations demand rugged automation solutions. PLCs are used to control crushers, conveyors, hoists, ventilation systems and safety interlocks. Their robust design and support for distributed I/O make them ideal for remote and hazardous environments. Integration with telemetry and condition monitoring systems helps operators optimise performance and reduce unplanned downtime.
Power Generation and Distribution
PLCs are widely used in substations, switchgear and distributed energy systems to manage control, protection and automation functions. They enable fast response to grid conditions, support load balancing and provide secure communication with supervisory systems. In renewable energy applications, PLCs help coordinate inverters, battery storage and grid interface equipment.
Building Management Systems
Modern buildings rely on PLCs to automate HVAC, lighting, access control and energy metering. These systems improve occupant comfort, reduce energy consumption and support sustainability goals. PLCs offer flexible integration with other protocols, making them suitable for both new builds and retrofit projects.
Transport and Infrastructure Projects
PLCs are used in traffic signal control, tunnel ventilation, rail signalling and smart infrastructure systems. Their reliability and deterministic control make them ideal for safety-critical applications. Integration with sensors, cameras and centralised platforms enables real-time decision-making and improved public safety.
