Terminology¶

This section introduces the major concepts for EnOS Edge.

EnOS Edge Device (Edge Device)¶

EnOS Edge Device, Edge Device in short, is the gateway device in the IoT Hub of EnOS Cloud. You need to register the gateway device in Dev Portal before using EnOS Edge.

Connectivity Service¶

Based on device protocol library, Connectivity Service enables users to connect Edge devices to EnOS Edge for dynamic modeling and asset management.

Connection¶

A connection is the communication channel that links EnOS Edge with other devices or systems.

A connection can access data from a sub-device or a batch of sub-devices.
A connection uses a protocol to communicate with the device (or system).
EnOS Edge supports two kinds of connection:
- Access connection
- Forwarding connection

Protocol¶

A protocol is a standard set of communication rules that allow devices to communicate with each other. Protocols can be classified as follows:

Standard protocol and private protocol
Access protocol and forwarding protocol
Application layer protocol and link layer protocol

Device Management¶

You can manage the connected Edge devices in the sub-device tab of EnOS Edge.

Device Control¶

EnOS Edge can accept control commands published by applications, convert them into protocol messages for device communication, and send them to the device to control the connected device.

Edge computing¶

Edge computing Service preprocess and calculate the model point in EnOS Edge. The EnOS Edge supports the following two types of edge computing:
