Case Studies

At a Glance

A large renewable power plant, supplying clean electricity to 95,000 residents, chose Moxa’s EDS-4000 series and MGate due to their robust cybersecurity certification, high reliability in demanding environments, and seamless support for IEC 61850 standards. This ensured secure, standards-compliant communication and long-term operational stability.

Business Challenge

Amid regulatory ambiguity, a coastal energy facility with six substations needed a durable, standards-compliant network solution that ensured long-term cybersecurity. The customer prioritized a secure, future-ready architecture adaptable to evolving compliance and harsh coastal conditions.

Solution & Results

Moxa’s IEC 62443-4-2-certified EDS-4000 series was selected for its strong compliance, rapid delivery, and proven field performance. Distributor support and successful prior deployments built trust. With 200 devices now in place, the site delivers 340 MWh of power daily, meeting the needs of 95,000 people. Field engineers highlighted the EDS-4000 Series’ usability and rugged design, positioning Moxa as a key player in future energy projects.

A European copper mine upgraded its core network with Moxa’s rugged, NIS2-ready switches, engineered to endure extreme heat, shock, and vibration. Chosen for their exceptional reliability, the new infrastructure not only boosts operational stability but also sets a resilient benchmark for future mining expansions across the region.

Business Challenge

To mitigate operational risk, each of the three mines selected a different network vendor. One mine faced the toughest environmental challenges, requiring ultra-rugged equipment resilient to continuous explosions, intense heat, and vibrations, while also ensuring full compliance with stringent NIS2 cybersecurity requirements.

Solution & Results

Moxa implemented a secure, user-friendly network with EDS and PT-G switches, chosen for their seamless compatibility, intuitive design, and minimal installation effort. Fast deployment and simplified troubleshooting empowered diverse operators on-site. With a proven track record and broad portfolio, Moxa outperformed the competition, delivering a compliant, uniform, and scalable infrastructure that now serves as the reference model for future mining expansions.

To ensure clean and safe water for millions, One of Africa’s largest bulk water utility needed to replace its outdated control systems. Moxa delivered a secure and reliable network backbone that connected PLCs, HMIs, remote I/Os, and wireless systems enabling the utility to meet today’s standards in both water quality and cybersecurity.

Business Challenge

The utility’s legacy systems had been running for over 15 years. These systems were not designed to meet today’s cybersecurity requirements, prompting the need for a modernized, more secure infrastructure. At the same time, the solution had to ensure high reliability and minimize downtime during the upgrade.

Solution & Results

The utility deployed Moxa’s IEC 62443-4-2 SL2 certified EDS-G4000 Series of managed switches and the EDR-G9010 all-in-one secure router to build a modern, cybersecure network backbone. The new infrastructure enables reliable, high-performance communication across PLCs, HMIs, remote I/Os, and Wi-Fi, while supporting simplified OT management and long-term scalability and thereby fulfilling the highest standards in water quality.
