Moxa is a well-known company that manufactures industrial networking and automation solutions, and one of their key offerings is IoT gateways. These devices are used to bridge the gap between field devices and cloud or enterprise systems in Industrial IoT (IIoT) applications. Let's break down Moxa IoT gateways in detail: 🔧 What is an IoT Gateway? An IoT gateway connects different types of field devices (sensors, PLCs, meters, etc.) to the internet or cloud services. It collects, processes, and transmits data. In industrial environments, gateways need to handle harsh conditions and support various industrial protocols. 🏭 Moxa IoT Gateway Overview Moxa’s IoT gateways are designed specifically for industrial environments. They support: Harsh temperature & electrical noise environments Industrial field protocols (Modbus, PROFINET, EtherNet/IP, etc.) Secure data transmission to cloud platforms Local processing (edge computing) 📦 Popular Moxa IoT Gateway Series 1. UC Series (e.g., UC-2100, UC-3100, UC-8200) Moxa's UC Series is widely used for IIoT applications. Here's a breakdown: Model CPU OS Support Interfaces Features UC-2100 ARM Cortex-A8 Debian, Yocto (Linux) 1x LAN, 2x Serial, USB Compact, low-power UC-3100 ARM Cortex-A8 Debian, Yocto Dual LAN, 3x Serial Wi-Fi, LTE option UC-8200 ARM Cortex-A7 dual-core Debian, Yocto, Azure IoT Edge Dual LAN, multiple serial ports, USB, LTE, Wi-Fi Edge AI support 🌐 Connectivity Options Ethernet, Wi-Fi, LTE/4G, Serial Protocol support: Modbus RTU/TCP OPC UA MQTT RESTful API CANbus Compatible with cloud platforms like: Azure IoT Hub AWS IoT Core Google Cloud IoT 🛠️ Software & Edge Intelligence Moxa Industrial Linux (MIL): A long-term support Linux distribution based on Debian, hardened for industrial use.
