View volume deviation totals using the PLM Deviation Array window

The Pipeline Monitoring (PLM) Deviation Array window lists:

• All volume deviation values for the last 60 minutes.

To access the PLM Deviation Array window

• Select Deviation on the PLM Controls menu.

  The PLM Deviation Array window appears.

  

  

The short, long-term, and extended term period values are the same as those appearing in the Deviation column on the PLM Control window. The Volume Units, which indicate what units the values are measured in, are displayed in the middle of the Deviation Array window.

The Last 60 Minute Values are the deviation for each minute over the last 60 minutes.

Note: The row numbers refer to the minute of the hour. For example, the value at row 30 is the deviation for the period from 29 minutes past the hour to 30 minutes past the hour.
