To enable data forwarding from DataTalk to external platforms, the OT/IT Gateway must first be configured and linked with selected tags in the project. The setup defines where, when, and how the data will be published to third-party systems.

Key Steps & Features

• Creating a Gateway
  • In the project tree, create a new gateway and assign it a name.
  • In the top menu of the gateway settings, choose the gateway type, which refers to the destination platform or service (e.g., AWS, Azure, SQL database, REST API).
  • Important: One gateway instance corresponds to one target service. If data needs to be sent to multiple platforms, separate gateways must be created for each.
• Defining Execution Triggers (Publishing Logic)
  • The trigger type determines when data should be sent:
    • Timer:
      Sends data at a regular time interval (e.g., every 1000 ms = every second).
    • Scheduler:
      Sends data at a specific time (e.g., every day at midnight).
    • Tag Trigger:
      Sends data when a specific tag reaches a defined value.
      Example: When a machine status tag changes to “1” (start), data is sent.
    • Tag Value Change:
      Sends data any time the value of a selected tag changes, regardless of the new value.
    • On Change:
      ???
• Platform Authentication
  • After selecting the platform type, fill in the connection credentials (e.g., API keys, server URLs, tokens).
  • Once completed, the gateway is active and ready to forward data.
  • Detailed connection guides are available in the “Publish Platforms” section.

Assigning Tags to a Gateway

• Navigate to the Tag Database.
• Select the tag(s) you wish to publish.
• In the “Gateway” column, check the box to open a list of available gateways created in the project.
• You can assign one tag to multiple gateways simultaneously.

Example: A single tag can be configured to publish its value to both Amazon AWS and a custom REST API endpoint.

The OT/IT Gateway setup enables scalable, flexible, and event-driven data integration between DataTalk and external systems—making it a critical component for real-time analytics, cross-system communication, and cloud-based infrastructure.
