Moxa: the trusted partner in automation

moxa automation

Railway operators from around the world have discovered new levels of operational efficiency by deploying Moxa railway automation technologies, such as intelligent wireless inter-carriage connections, millisecond-level ethernet redundancy, and WLAN roaming solutions.

With more than 35 years of experience in industrial networking, Moxa has a proven record of developing long-lasting and reliable devices. In addition, Moxa has been part of hundreds of successful deployments in major railway systems worldwide to enhance passenger comfort and network operations.

Moxa’s portfolio includes more than 400 railway-specific products ranging from onboard to trackside, and end devices to network architecture.

Moxa senior engineer Angie Chen tells Rail Express that the company provides integrated IP solutions that enhance the safety and efficiency of railway operations.

“Its end devices include computers tailor-made for deployment on trains, and controllers and remote I/O products for condition monitoring. For railway IP network design, it uses its industrial networking expertise to provide a variety of ethernet switches for onboard, trackside, train stations, control centres, wireless AP/client for train-to-ground communications, and smart network management software to help optimise the efficiency of the network,” she said.

“The hundreds of successful deployments of Moxa’s products in major railway systems such as CCTV, PIS (Passenger Infotainment Systems), CBTC (Communication-based Train Control), and TCMS (Train Control Management Systems) have proven that our leading IP solutions are capable of providing high reliability and network availability that meet the demands of the rail industry.”

To bring more devices to the network, MOXA’s terminal server is an important bridge between legacy serial devices and IP-based networks, facilitating effortless integration without the need for costly upgrades. 

In the latest generation, the terminal server can also encrypt the serial data to ensure secure data transmission in the network. 

Apart from the serial terminal server, MOXA offers gateways and converters that covers major industrial protocols, including PROFINET, EtherNet/IP, and Modbus TCP, enhancing the competitiveness of MOXA’s edge solution.

Moxa’s reputation in the industry is anchored by our redundancy protocols, Turbo Ring and Turbo Chain, offering swift recovery times and reduced cabling costs compared to traditional ring coupling methods,” Chen said.

She said that three key trends in network connectivity had emerged in recent years: cybersecurity, higher bandwidth, and increased Power over Ethernet (PoE) capabilities.


“Cybersecurity is gaining more prominence in industry because of potentially devastating impact of cyberattack in critical infrastructure,” Chen said.

“Moxa leads the industry by achieving compliance with the IEC 62443-4-1 standard, which specifies process requirements for the secure development of products used in industrial automation and control systems.

“At AusRAIL, we will also showcase our first EC-62443-4-2 certified industrial switch. Additionally, the visitor can see security guidance in Moxa’s network management software, which lets users easily implement a secure network.”

Higher bandwidth

As the number of networked devices continues to surge, the volume of data increases and push the demand for higher bandwidth in wayside networks.

“Moxa’s latest-generation DIN-Rail switch series boasts 2.5G ports, effectively addressing this need,” Chen said.

“Additionally, the modular switches feature 10G ports, facilitating high-speed data communication, streamlining field wiring, and reducing installation costs, thus enhancing modern railway applications.”

Higher PoE power output

To accommodate the escalating connectivity and power requirements of security infrastructures, some devices such as pan-tilt-zoom robotic cameras and wireless access points demand higher power output.

“Moxa’s latest power-over-ethernet (PoE) switches conform to the highest IEEE 802.3bt PoE++ standards, delivering up to 90 W per link to provide full power for PTZ cameras and wireless devices,” Chen said.

“Distinguishing ourselves from commercial PoE solutions, our robust products boast cybersecurity features, robust EMI/surge protection, and a wide operating temperature range of -40 to 75°C, designed to withstand harsh environments.

“Featuring Smart PoE technology, our PoE switches can autonomously detect the power class of powered devices (PDs), streamlining configuration and deployment. They can conduct failure checks and automatically reboot PDs to ensure a stable system operation.”
