Output Curves Export & Posting

This document explains how tightening curve data is automatically exported as JSON and posted to the sys3xx gateway via HTTP request, configured through the outputs.json file.

Configuration File: outputs.json​

The outputs.json file controls the export and posting behavior. It is located alongside appdata.json in the application configuration directory.

Example outputs.json:

{
  "OutputHttpURL": "http://127.0.0.1:8889/x",
  "TempStoragePath": ""
}
  • OutputHttpURL: The HTTP endpoint URL where the JSON data will be posted. This should point to your sys3xx gateway.
  • TempStoragePath: Reserved for future use (local storage).

Automatic HTTP Posting to sys3xx​

When a tightening cycle completes, the application automatically:

  1. Records the tightening curve data (torque, angle, time points).
  2. Generates a JSON payload containing the cycle information and curve data.
  3. Posts the JSON to the URL specified in OutputHttpURL using an HTTP POST request with Content-Type: application/json.

The posting is asynchronous and fire-and-forget - it logs success or failure but does not block the tightening process.

Integration with sys3xx Gateway​

To integrate with sys3xx:

  1. Ensure sys3xx gateway is running and listening on the configured URL.
  2. Set OutputHttpURL in outputs.json to point to the gateway's endpoint (e.g., http://127.0.0.1:8889/x).
  3. The application will automatically send tightening data after each cycle.

Disabling Export​

To disable automatic posting, remove or leave OutputHttpURL empty in outputs.json.

Troubleshooting​

  • No data received: Check that OutputHttpURL is correctly set and the sys3xx gateway is accessible.
  • Posting errors: Review application logs for HTTP error codes or connection issues.
