Introduction

The AIG-302 Series advanced IIoT gateways connect Modbus RTU/ASCII/TCP devices to platforms such as Azure cloud and MQTT. The gateways support the Modbus TCP server mode, enabling simultaneous transmission of data to cloud platforms and your local SCADA system.

Boost Edge Computing Capabilities With Azure IoT Edge

AIG-302 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-302 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-302 and Azure IoT Edge support make your system both flexible and easily expandable. At the same time, its seamless integration with Azure cloud services allows you to effortlessly extend cloud capabilities to edge devices.

Built-in Ready-to-use Data Preprocessing Functions, No Coding Required

Energy Management Systems collect energy data such as average power generation and energy efficiency. This data is then used to display on-site conditions, observe the energy trend, and optimize energy usage. Most energy management systems require meaningful data and hence edge gateways are expected to preprocess data collected at field sites before transfer to cloud applications. Some applications may require certain actions to be performed within a short time frame on the preprocessed data. AIG-302 ready-to-run IIoT gateways come with value-added functions and an intuitive UI that simplify data preprocessing and distributed device management to just a few clicks.

Secure Remote Access Reduces Maintenance Costs

The AIG-302 comes with powerful troubleshooting tools to diagnose issues with protocol statuses and capture and analyze traffic packets, enabling engineers to identify the root cause of issues and quickly bring the operation back to normal. Moreover, AIG-302 provides secure remote access allowing maintenance engineers to fix issues remotely, saving time and effort as well as reducing the downtime in energy management systems. External connections can be encrypted using OpenVPN or TLS, ensuring secure communication.

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.
