PI System Explorer Attribute Created from Analyses: Pi Point Cannot be Found?

Are you stuck with an error message saying “PI point cannot be found” when trying to create an attribute from analyses in PI System Explorer? Don’t worry, you’re not alone! This article will guide you through the steps to troubleshoot and resolve this issue, so you can get back to creating powerful attributes in no time.

Understanding the Error Message

Before we dive into the solution, let’s understand what’s happening behind the scenes. When you try to create an attribute from an analysis in PI System Explorer, it attempts to reference a PI point that’s supposed to be associated with the analysis. However, if the PI point is missing or not properly configured, you’ll encounter the “PI point cannot be found” error.

Causes of the Error

There are a few reasons why you might see this error message:

• The PI point is not created or configured correctly.
• The analysis is not correctly linked to the PI point.
• The PI point is not available in the current context or AF database.

Step-by-Step Troubleshooting Guide

Fear not, dear reader! Follow these steps to identify and fix the issue:

Step 1: Verify PI Point Existence

Open PI System Explorer and navigate to the AF database where your analysis is located. Check if the PI point exists by searching for it in the PI Point Explorer:

[AF Database] > PI Points > Search

If the PI point doesn’t exist, create it using the PI Point Editor:

[AF Database] > PI Points > New PI Point

Step 2: Check PI Point Configuration

Ensure the PI point is properly configured:

• Verify the PI point’s data type matches the analysis output.
• Check the PI point’s scan class and compression settings.
• Make sure the PI point is not disabled or in an error state.

Step 3: Verify Analysis to PI Point Linkage

Confirm that the analysis is correctly linked to the PI point:

[AF Database] > Analyses > [Your Analysis] > Configuration

In the analysis configuration, check the “Output” section and ensure the correct PI point is selected:

Field	Value
Output	[Your PI Point]

Step 4: Check AF Database Context

Verify that you’re working in the correct AF database and context:

[AF Database] > [Your AF Database]

Make sure you have the necessary permissions and access to the AF database and PI points.

Step 5: Restart PI System Explorer

Sometimes, a simple restart can resolve the issue. Close and reopen PI System Explorer to ensure any changes take effect.

Solution Implementations

Now that we’ve troubleshooted the issue, let’s implement the solutions:

Creating a New PI Point
