Sigma – Best Practices for Retrieving Logged Data

[Product_Support]

Issue

What is the most effective method for retrieving logged data from Sigma controllers?

Product Line

Satchwell BAS & Sigma

Environment

• Sigma controllers and ICs
• Sigma server

Cause

Sigma logged data is not always immediately available for viewing. Users may need access to data that has not yet been uploaded to the Sigma server.

Resolution

Sigma controllers and ICs can upload logged data to the Sigma server when their internal data tracks reach a certain capacity. While this automatic upload is the default and recommended method, it can be unpredictable. For more controlled access, two manual retrieval methods are available:

---

Method 1: Manual Upload via System Diagnostics

1. Open System Diagnostics.
2. Select the desired controller.
3. From the Options menu, choose:
   • Upload All Logged Data, or
   • Upload Selected Logged Data.
4. The retrieved data will be available for review.

✅ Use this method when immediate access to specific controller data is required.

Method 2: Scheduled Retrieval via System Setup

1. Navigate to System Setup.
2. Select Scheduled Actions.
3. Create a new action:
   • Choose Retrieve Controller Logs.
   • Specify the target controllers
     • e.g. All Controllers

       

     • e.g. A defined group such as Controllers

       

4. Add a schedule:
   • Ensure retrieval actions are spaced at least 15 minutes apart to avoid system overload.
