The OT/IT Gateway in DataTalk serves as a bridge between operational technology (OT) and information technology (IT), enabling seamless data transmission from devices to external systems. It collects data from various connections and stores it in the Tag Database, then publishes it to third-party platforms in a unified format.

Key Features

• Protocol-Agnostic Data Integration
  • Supports combining data from multiple communication protocols (e.g., Ethernet/IP, MQTT, REST API).
  • Useful in complex environments where different devices and technologies operate in parallel.
• Unified Data Output
  • Transforms and publishes tag values into a standardized format, regardless of their source protocol.
  • Allows consistent data delivery to cloud services or databases, including:
    • Amazon Web Services (AWS)
    • Microsoft Azure
    • Supported SQL databases (e.g., PostgreSQL, MSSQL)
    • RestAPI
    • MQTT
• Trigger-Based or Periodic Publishing
  • Data can be sent at regular time intervals (e.g., every minute, every hour).
  • Or, data can be pushed based on specific events, such as:
    • A tag value change, like a machine status shifting from idle (0) to running (1).
    • Start/stop of a production cycle.

Example Use Case

Imagine a production line using various technologies:

• A PLC with Ethernet/IP,
• An MQTT-enabled sensor,
• And data fetched via the REST API.

With the OT/IT Gateway, you can unify all variables from these sources and send them in a single format to your cloud analytics system—making cross-platform integration and centralized analysis straightforward and efficient.

The OT/IT Gateway is essential for modern industrial environments aiming to adopt Industry 4.0 practices, as it enables scalable, real-time, and cross-platform data sharing from edge devices to enterprise-level systems.
