IoT SiteWise OPC UA data source simulator

The IoT SiteWise OPC UA data source simulator component (aws.iot.SiteWiseEdgeOpcuaDataSourceSimulator) starts a local OPC UA server that generates sample data. Use this OPC UA server to simulate a data source read by the IoT SiteWise OPC UA collector component on an AWS IoT SiteWise gateway. Then, you can explore AWS IoT SiteWise features using this sample data. For more information about AWS IoT SiteWise gateways, see Using AWS IoT SiteWise at the edge in the AWS IoT SiteWise User Guide.
