Introduction
AIG-501 Series advanced IIoT gateways are designed for Industrial IoT applications, especially for distributed and unmanned sites in harsh operating environments. The gateways implement Modbus RTU/TCP master/client protocols which can help you to effortlessly collect data from Modbus devices. Moreover, Azure IoT Edge software is preloaded and seamlessly integrated with the AIG-501 to enable easy, reliable, yet secure sensor-to-cloud connectivity for data acquisition and device management using the Azure Cloud solution. With the use of the ThingsPro Proxy utility, the device provisioning process is easier than ever. Thanks to the robust OTA function, you never have to worry about system failure during software upgrades. With the Secure Boot function enabled, you can prevent malicious software injection attacks, especially during the boot-up process.
