¶ Analyze (Visualization)
The Analyze tool via the visualization engine provides options to perform simple on-demand analysis of data. Sensor data is organized by the metadata (asset hierarchy) provided during onboarding of a plant. Once the tags are chosen, a user can perform one or more of the following:
- Trends: Choose from single or multi-line trends and view more than a year’s data in just a few seconds. Users can also zoom in/out, pan, choose colors of lines and sampling frequency of data
Figure 82. Analyze page
-
Scatter Plot: Helps compare any two parameters and the change in their relationship over a period of time. The user can choose to view comparisons of these parameters over successive days or weeks or months
-
Tabular: Sensor Values are displayed under 'TAG DATA'. The statistics min, max, median and standard deviation based on each load bucket is displayed under 'STATISTICS'
Figure 83. Table tab
The areas a user can focus on include identifying any trends that may be developing, such as equipment degradation or deterioration of plant performance, and take corrective action before the issue becomes a significant problem.
Identifying relationship between two tags against each other to identify any correlations between them that may indicate a potential issue or provide insight into optimizing the plant's performance.
compare the current performance of the plant to its original design specifications to identify any deviations from the design specifications and take corrective action to optimize plant performance.
