With capabilities such are resume file transmission, over-the-air (OTA) upgrades, and Secure Boot, the AIG series gateways, located in remote sites, can be upgraded and maintained to ensure their continuous availability and effectively protected against cyberattacks. The gateways also come with built-in recovery functions to enable rollback to a previous stable firmware version for uninterrupted network connectivity and system stability at remote sites during unplanned shutdowns or a system crash. The ThingsPro tool simplifies the bulk provisioning of IIoT gateways and remote software upgrades.
