Understanding and Resolving the "Pt Created" Status in PI System

Managing and troubleshooting data collection in the PI System is a critical task for engineers and system administrators. One common issue encountered during the configuration of data points is the "Pt Created" status. This blog post aims to provide an understanding of this status and offer guidance on resolving it.

What Does "Pt Created" Mean?

In the PI System, "Pt Created" is an initial status indicator for a PI point (or tag) that has been freshly created but has not yet begun receiving or updating with live data. This message typically appears when there is some misalignment or misconfiguration between the PI point settings and the data source or interface.

Steps to Troubleshoot "Pt Created"

1. Check Interface Configuration: Ensure that the PI points are correctly linked to the right interface. This involves checking the following settings:

   • Location1 Tag Attribute: This must match the interface ID configured in the PI Interface node. Incorrect settings here can result in the interface not recognizing the tag.
   • Point Source: Verify that the point source in the PI point matches the one designated for your interface in PI ICU (Interface Configuration Utility).

2. Evaluate Network Communication: Check if there are any network issues between the PI Server and the data source. Network problems can prevent data from flowing properly, keeping the tag in a "Pt Created" state.

3. Review Security Settings: Ensure the security settings allow the interface to read and write to the tag. Sometimes, restrictive security configurations can prevent successful data collection.

4. Scan Class Overloading: If your scan class is overloaded with too many tags, new tags may not begin collecting data immediately. Consider distributing tags into multiple scan classes or reviewing scan frequency settings.

5. Correct Point Attributes:

   • Change settings such as Location3 to ensure they align with the interface's expectations or network requirements. As one resolution pointed by users, setting Location3 to ZERO has resolved issues in receiving data.

6. Monitor Message Logs: Inspect the PI Message Logs to identify any error messages that could give hints to the problem. Logs often contain valuable information about mismatched configurations or communication failures.

Conclusion

The "Pt Created" status is not an erroneous state but rather a starting point for new tags that require proper configuration and communication setups to begin updating correctly. By methodically reviewing and adjusting point configurations and network settings, you can effectively troubleshoot and resolve this status, ensuring smooth data collection in your PI System.
