28.2         Functionalities and Features

This Guide describes the functionalities, including data communication, data synchronization, and IoT administration.

Data communication

In Cloud-based WebAccess, large amounts device data are uploaded to the cloud via the MQTT web socket protocol. The MQTT web socket protocol also supports the local and cloud devices to communicate back and forth.

Data synchronization

To advance our goal of being customer-centered, WebAccess provides a data synchronization service called “Plug and play”. “Plug and play” are designed to synchronize the data configuration between local and cloud devices.

IoT administration

The connecting status between ground-based configuration and cloud-based configuration can be monitored by using the MQTT web socket protocol.
