Clock scheduling

Clock scheduling uses scan classes to calculate values at regular intervals, such as every hour, five seconds, or 20 minutes.

• Scan Class

  Choose a scan class to schedule calculations based on the scan frequency of an available scan class.

  Note: All available scan classes are listed in the Scan Class menu. If the menu does not appear, make sure the pipeschd.bat file is registered in the PI Interface Configuration Utility (ICU).

• Start Time field

  Specify an optional initial start time and offset for the calculation interval. For equations that use more than one point, use scan class offsets to perform calculations in a specific order.
