Sigma - How to Delete Logging Configuration from a Controller (Release 4.04)

[Product_Support]

Issue

How can logging configuration be removed from a controller in Sigma release 4.04?

Product Line

Satchwell BAS & Sigma

Environment

Sigma Release 4.04

Cause

Sigma 4.04 does not provide a direct method to download an empty logging configuration file to a controller. This limitation requires a manual workaround to effectively remove logging configurations.

Resolution

There are two recommended methods to delete logging configurations from a controller:

---

Method 1: Manual File Deletion via Explorer

1. Open Sigma and navigate to the Logging Configuration section.
2. Delete the unwanted logging data set from the configuration.
3. Using Windows Explorer, go to the controller’s folder location.
4. Locate and delete the logging configuration file.
   • Example filename: T0025400.100
     • T00254 = Server
     • 00.100 = Controller
5. In Sigma System Diagnostics, re-download the logging configuration to the controller to apply the changes.

Method 2: Minimal Logging Configuration

1. In Sigma, go to Logging Configuration.
2. Open the required log data set.
3. Delete all objects in the data set except one.
4. Set the remaining object to log very infrequently.
5. Save and download the configuration as usual.
6. Optionally, delete the log data set entirely.
   • This will result in the controller logging only one object at a minimal rate.
   • Upon the next download of controller files, logging will be effectively removed.
