Keeping Connectivity Simple and Cybersecure for Your Serial Devices

At-a-glance

Air pollution, responsible for millions of deaths, is mainly caused by industry and transportation. The 2020 lockdown highlighted improvements in air quality, leading governments to enforce stricter policies to protect health and the economy.

Business Challenge

A Continuous Emission Monitoring System (CEMS) tracks pollutants like SO2 and NOx to ensure Environmental Protection Agency (EPA) compliance. Factories must meet specific data requirements and avoid fines for inaccurate data or exceeding limits, requiring reliable solutions for accurate data transmission.

Solution & Results

Moxa ensures reliable and secure data transmission with a comprehensive solution that includes managed Ethernet switches for network redundancy, the NPort 5000 Series for seamless serial-to-Ethernet connectivity, and the ioLogik E1200 & 2500 I/O Series integrated with MX-AOPC UA software. This setup not only enables smooth communication between serial and Ethernet devices, but also safeguards data integrity by locally backing up critical information and automatically recovering any missing data once the network is restored.

At-a-glance

A data center provider strengthens cybersecurity after facing data loss and penalties from cyberattacks. The initiative focuses on securing both server rooms and vulnerable power sources with exposed communication interfaces.

Business Challenge

The corporation will conduct monthly vulnerability scans and work with manufacturers to address security issues. IT departments must also secure OT devices like switchgear and PDUs, which require ongoing monitoring and firmware updates.

Solution & Results

Moxa’s MGate MB3170 and MB3660 protocol gateways are designed with embedded security based on the IEC 62443 standard. Regular vulnerability scans and tools like MXconfig and MCC simplify firmware updates, enhancing device security for both OT and IT users.

At-a-glance

The US state Department of Transportation (DOT) aims to centralize traffic control across five Traffic Management Centers (TMCs), using real-time data to manage incidents and communicate updates to drivers, ensuring safer and more efficient travel.

Business Challenge

Requirements include a gigabit network backbone for video data, NEMA TS2 compliance, network redundancy, secure data encryption, efficient traffic management, industrial durability for harsh conditions, and fiber interfaces for long-distance, scalable transmission.

Solution & Results

To connect serial-based traffic equipment like vehicle loop sensors and variable message signs to the Ethernet network, the DOT deployed Moxa’s NPort 6450-T terminal servers. These devices enabled secure, real-time access to legacy systems without costly upgrades and perform reliably in extreme roadside conditions. Paired with Moxa’s EDS-510A-T switches for a secure, redundant gigabit backbone over long distances, the solution supports both legacy and modern devices for statewide traffic management.
