More About Moxa
Moxa focuses on industrial networking and edge connectivity solutions designed for factory automation, transportation, energy, marine, and other industrial environments where equipment must operate in constrained and harsh conditions. Its portfolio spans industrial Ethernet switches, industrial wireless devices, industrial computers, and protocol gateways that connect programmable logic controllers (PLCs), remote terminal units (RTUs), sensors, and other field assets to Supervisory Control and Data Acquisition (SCADA) systems and enterprise applications. These products are positioned for use in OT environments that require deterministic communication, extended temperature operation, and long lifecycle support.
Moxa’s industrial Ethernet switches and routers (industrial networking) are used to build Layer 2 and Layer 3 networks for factories, substations, rail systems, and process plants. They support architectures such as ring, mesh, and redundant topologies, and commonly rely on protocols like Ethernet/IP, Modbus Transmission Control Protocol (TCP), and PROFINET for integration with automation systems. Many offerings include support for managed switching features such as VLANs, Quality of Service (QoS), port security, and network redundancy mechanisms suitable for Indirect Evaporative Cooling (IEC) and IEEE industrial standards. Wireless portfolio elements provide Wi-Fi and cellular connectivity options for mobile assets, remote sites, and transportation applications.
The company’s serial device servers, media converters, and protocol gateways (industrial connectivity) bridge RS-232/422/485, CAN, and other fieldbus interfaces to IP networks. These devices are used where legacy equipment must remain in service while still participating in modern monitoring, control, and analytics workflows. Protocol gateways commonly translate between Modbus RTU, Modbus TCP, DNP3, IEC 61850, and other industrial protocols, which supports integration between substation devices, meters, and SCADA or energy management systems. This capability places Moxa in categories such as protocol conversion, serial-to-Ethernet connectivity, and OT data integration.
Moxa also offers industrial computers and edge gateways (edge computing) that host applications for data acquisition, local processing, and secure communication with cloud and data center platforms. These systems typically support Linux or Windows, container-based workloads, and SDKs for building OT data pipelines. They are used in architectures where data from PLCs, sensors, and machines is aggregated at the edge, filtered, and then forwarded to analytics, historian, or asset management systems via Message Queuing Telemetry Transport (MQTT), Open Platform Communications Unified Architecture (OPC UA), or HTTP-based APIs. This positions Moxa in the edge infrastructure and Industrial IoT (IIOT) gateway segments.
On the software side, Moxa provides network management, configuration, and security tools (network management) to monitor device status, bandwidth utilization, and topology, and to apply firmware updates and configuration templates. These tools help enterprises and operators maintain large distributed deployments of industrial switches, gateways, and wireless devices. Security features typically include access control, user authentication, and functions that align with current practices for segmenting OT networks and supporting defense-in-depth architectures.
Across its portfolio, Moxa aligns with marketplace categories including industrial Ethernet networking, serial and protocol connectivity, industrial wireless, industrial computers and edge gateways, and industrial network management software. Its offerings are used by enterprises, system integrators, and OEMs building automation and control systems that require reliable communication between field devices, control systems, and enterprise or cloud applications.
