Creating Calculations using Expressions
- Configure a new analysis template to determine the total uptime for a particular asset type over a 24-hour period. What attribute template would you use as the input to this expression? What Performance Equation function can you utilize to determine the total uptime? View the daily uptime inside of PI DataLink.
- Set up a new analysis template of type expression to calculate the daily average for a particular process at your facility. Which Performance Equation function would you use? What would the parameters be for this function? After the analysis is configured, go ahead and backfill the analysis for a particular element. View the output attribute inside of PI Coresight.
Optional: If you want to visualize the data as a step function inside of PI Coresight, when you configure tag creation, set the Step tag attribute to true.
