🛢️ Industry-Specific Applications

Upstream Oil & Gas: Automate wellhead control, separator management, and tank farm operations across remote production sites. The CPU's autonomous operation ensures continuous production monitoring even when satellite or cellular links are temporarily unavailable, storing data locally for later transmission.

Pipeline & Midstream: Deploy at compressor stations, metering skids, and custody transfer points where precise flow measurement and regulatory reporting demand reliable edge computing. Built-in DNP3 protocol ensures seamless integration with utility-grade SCADA masters.

Water Distribution Networks: Control lift stations, pressure-reducing valves, and reservoir levels across geographically dispersed municipal infrastructure. Low power consumption enables solar-powered installations in areas without grid access.

💡 Innovative Control Solutions

Edge Intelligence: Execute complex control algorithms locally—PID loops, batch sequencing, alarm management—reducing dependency on central SCADA systems and improving response times from seconds to milliseconds.

Cybersecurity Hardening: Integrated firewall, encrypted communications, and role-based access control protect critical infrastructure from cyber threats while maintaining compliance with NERC CIP and API 1164 standards.

Retrofit Modernization: Replace aging RTUs and PLCs without rewiring field devices. The ControlWave Micro's flexible I/O architecture accepts legacy 4-20mA, discrete, and serial signals, accelerating brownfield upgrades while preserving existing infrastructure investments.

🔧 Engineering & Deployment

Program using ControlWave Designer software with intuitive graphical interfaces for ladder logic and function blocks. Built-in simulation mode validates logic before deployment. Hot-swappable design allows CPU replacement without de-energizing the chassis, minimizing downtime during maintenance windows.
