AWS IoT SiteWise now supports data ingestion using ModBus TCP and EtherNet/IP (EIP) protocols. You can do so by adding Modbus or EIP devices as data sources to your SiteWise Gateway. For data ingestion from OPC-UA data sources, you can now customize the scan mode and scan rate along with specifying deadbands. Lastly, you can provide a custom AWS IoT Greengrass StreamManager stream as a destination for protocol data.
