A Moxa IoT Gateway is a rugged industrial device that connects legacy equipment and sensors to cloud platforms or SCADA systems, enabling Industrial IoT (IIoT) and remote monitoring.
It acts as a bridge between OT (Operational Technology) and IT (Information Technology), helping industries like manufacturing, energy, and transportation digitalize and automate operations.
🧠 Key Functions
Function Description
Protocol Conversion Converts protocols like Modbus, OPC UA, MQTT, etc., to communicate between field devices and cloud.
Edge Computing Can process and filter data at the edge before sending it to reduce bandwidth and latency.
Secure Remote Access Enables safe remote device monitoring/configuration.
Data Logging Collects and stores data locally if the network goes down.
Cloud Connectivity Supports Azure, AWS, Alibaba Cloud, etc.
🔧 Key Features of Moxa IoT Gateways
