The InfluxDB TagProvider uses InfluxDB as a Historian Target Database for storing time-series data. Configure this TagProvider to integrate time-series data into your solution, facilitating data storage, retrieval, and analysis. This setup provides a method for managing historical data within the Unified Namespace.allow dynamic retrieval of data from InfluxDB database, as well to save tags values to the InfluxDB databases. It can be used in read-only mode mode, or updating values, using as an Unified Namespace TagProvider, or it can also be used in Historian, Storage Locations, to act as one of locations where the Historian Module can save its data.

Configuration
To set up InfluxDB as a TagProvider, navigate to Unified Namespace → TagProvider Connections and select the InfluxDB Connector. Or the same configuration dialog will be presented when selecting InfluxDB from Historian → StorageLocations.
System Requirements
This TagProvider requires the user to have access to an InfluxDB Server with support for API Version 2.0 or greater.
Connection Parameters
Field | Description |
|---|---|
Provider | Specifies the system the TagProvider will interface with. In this case, it interfaces with the InfluxDB Connector. |
Access Mode | Determines permissions for interacting with tags. Read allows only data reading. Write permits only data writing. ReadWrite enables both reading and writing. |
Name | User-defined name for the TagProvider instance. Identifies the specific configuration in the system. |
Description | Defines a short description for the TagProvider's purpose or the systems it interfaces with. Provides context for its usage. |
ProtocolOptions | Defines specific communication settings for the connection to the device. |
Connection | Defines connection settings for the InfluxDB, including IP address, port, token, bucket, and organization. |
IP Address | Specifies the IP address of the InfluxDB server. |
Port | Sets the port number used for communication with the InfluxDB server. |
Token | Specifies the token for authentication with the InfluxDB server. |
Bucket | Defines the bucket within InfluxDB to retrieve or store data. |
Organization | Specifies the organization associated with the InfluxDB instance. |
Test | Verifies the connection settings to ensure successful communication with the specified server. |
ConnectionString | Displays the full connection string used to connect to the InfluxDB server. Provides a summary of all connection parameters. |
- Collector: Specifies the type of Collector to be used. Each one have a specific behavior in Runtime. Options are:
- Default: Connects to any InfluxDB Database without any custom TreeView is based only on Filter configuration.
- SolutionHistorian: Is used to Write ProjectTags Historian data in a custom.
- Filters field will always be disabled, with measurement and field columns added to.
- When Provider is used as Historian, Historian TableName will be used as measurement.
- TreeView structure will behave different than Default and MQTT More details available in following sections.
- MQTT: Is used to Read Data that was stored using Telegraf’s MQTT Plugin pre-defined column structure.
- The Topic information MUST be stored in a column named topic.
- Filters field will always be disabled, with measurement, topic and field columns added to
- TreeView structure will behave different than Default and tProj Historian.More details available in following sections.
- Filters: Defines a hierarchical order for columns, separated by comma (","), when assembling the TreeView.
- You can browse the columns to be discarded at the "+"
- Click on + or - to add / remove And Up/Down arrows to change the filter order.

When using the InfluxDB in conjunction with Unified Namespace TagProvider, the Collector Default and MQTT can be used. When using the InfluxDB as a Historian Storage Location, the Collection SolutionHistorian shall be used. |
The Filters are used to define the Query to be executed when assembling the TreeView. In this example with measurement and field,the structure would be as follows:

TagProvider connections cannot create new CustomColumns in InfluxDB Database, only access existing ones. To create new CustomColumns, use the Device Module Configuration. |
