Introduction

The AIG-502 is a robust Industrial IoT (IIoT) gateway designed to provide secure and reliable data communication for industrial applications. Compliance with the IEC 62443-4-2 Security Level 2 requirements ensures secure network connectivity, data transmission, and device authentication. The AIG-502 is equipped to acquire field data via Modbus RTU, ASCII, and TCP protocols, enabling seamless integration with the Azure cloud platform. With ample computing power, it supports advanced edge computing capabilities using Azure IoT Edge modules, making it an ideal solution for industries seeking to enhance data-driven operations securely and efficiently.

Boost Edge Computing Capabilities With Azure IoT Edge

AIG-502 supports Azure IoT Edge to bring in a multitude of benefits including edge computing capabilities, reduced bandwidth costs, flexibility and scalability, seamless integration with Azure services, and ease of management and update. Specifically, with the AIG-502 processing data locally, it not only offers rapid responses and low latency but also effectively reduces network bandwidth usage, thereby cutting costs. Additionally, the modular design of the AIG-502 and Azure IoT Edge support make your system both flexible and easily expandable. At the same time, AIG-502’s seamless integration with Azure cloud services allows you to effortlessly extend cloud capabilities to edge devices.

Reliable Software Updates With Easy Installation and Recovery

The software update function ensures easy, reliable, and secure system upgrades. Through the web console, users can install Debian, and specific patches using Debian APT, or apply a comprehensive update pack provided by Moxa. Updates can be retrieved online or manually uploaded with options for immediate or scheduled installation. The function also supports download resumption and automatic recovery, providing a seamless and resilient update experience to keep systems running smoothly.

Security Dashboard Optimized for Detecting Security Issues

A security dashboard utilizes device scans to identify potential cybersecurity threats from multiple angles, such as during account settings management, application networking, application resource usage monitoring, product certificates deployment, service settings modifications, and system status checks. Upon detecting threats, a mitigation plan is recommended to resolve issues.
