Provider

Specifies the system the TagProvider will interface with. In this case, it interfaces with the Hub for Server Communication.

Access Mode

Determines permissions for interacting with tags.

Read allows data reading.

Write permits data writing.

ReadWrite enables both reading and writing.

Name

Identifies the tag provider connection. Differentiates multiple connections within the system.

Description

Provides details about the connection. Helps users understand its purpose.

Connection

Shows the parameters used for establishing the connection.

Listening Port

Specifies the port for communication. Directs network traffic through the assigned port.

AccessKey

Manages authentication for the connection. Protects access based on security requirements.

Definition

A TagProvider that facilitates runtime data access and exchange. It operates as a hub, aggregating and distributing namespace information across multiple solutions.

Purpose

Enables real-time and historical data retrieval from multiple runtimes. Supports unified access to tag values, alarms, and server states across distributed systems.

Functionality

Provides a centralized connection for accessing runtime data. Manages namespace visibility based on access levels. Supports alarm status retrieval, acknowledgment, and trend history.

Application

Used in environments where multiple runtimes need synchronized data access. Configured at startup with alias, host, port, and access key settings. Accessible through TCP communication.

Configuration

Requires defining a listening port, access key, and access mode. Runtime solutions must enable "Publish to DataHub Service" and specify connection parameters, including alias and host settings.

Usage

Users configure the runtime to publish data and connect to the hub. Clients query namespace data using the defined access levels. Alarm interactions and tag updates occur through read/write operations.
