Raw Points

Overview

Raw Points, the most basic Device Attached Points, are the foundational telemetry streams in Bazefield. They represent real-time data directly sourced from physical devices like SCADA systems, PLCs, ODBC databases, or APIs. These points are minimally processed and serve as the first layer of data ingestion into the Bazefield platform. They also provide the means to write back to SCADA systems or APIs for Asset Control.

Key Characteristics

• Direct Mapping: Raw Points are mapped straight from external sources, often via the Bazefield Edge Buffer.

• Minimal Processing: Only basic scaling or validation is applied to preserve the integrity of the original signal.

• Time-Series Format: Each point includes a timestamp, value, quality flag, and a unique name (e.g., ActivePower).

• Long-Term Storage: Time-series data is stored in the Bazefield HISTORIAN database for long-term and performant data access.

Data Structure

Each Raw Point consists of:

• Name: Identifies the normalized signal (e.g., WindSpeed); the most generic part of the Tag Name (e.g., WP1-T001-WindSpeed)

• Timestamp: When the data was recorded

• Value: The actual measurement (e.g., 12.4 m/s)

• Quality Flag: Indicates data reliability (when the source device supports it)

Example

A wind turbine might expose a SCADA tag like:

WP1.T001.P_ACT

• WP1.T001: Asset identifier (e.g., Turbine 1 of Wind Plant 1)

• P_ACT: Vendor-defined signal for Active Power

In Bazefield, this becomes a Device Point named P_ACT, which is normalized into a Domain Point named ActivePower:

Why Raw Points Matter

✔️ Real-Time Monitoring: Enables immediate visibility into asset behavior.

✔️ Data Fidelity: Preserves original sensor data for traceability.

✔️ Foundation for Analytics: Serves as input for calculated points, KPIs, and alarms.

✔️ Vendor Integration: Supports diverse SCADA and device protocols.
