Synchronization of device conditions and properties with device twins

Connected Field Service includes a representation of customer assets and devices that can be registered within Azure IoT Hub to enable messages to flow through Azure IoT Hub to create alerts.
In the Spring ‘18 release, in addition to receiving messages that require action, Connected Field Service uses the Azure IoT device twin capability. The device twin, which is kept in sync with physical devices, is a JSON document that holds metadata and configuration data, as well as a virtual cloud representation of physical devices.
Connected Field Service communicates with device twins to allow devices to report operating conditions such as device state, heartbeat for connectivity speed, and machine vibration. Field service operations managers gain visibility into device conditions and properties on a graphical dashboard. For example, the capacity of a tank can be monitored through IoT Hub and represented on the dashboard. When capacity reaches a threshold, an alert is sent to designated users for follow-up action.
