Design engineers should identify all process data that will be used in systems external to the process control system. This can be key performance indicators (KPIs) or efficiency values such as energy per unit volume treated, chemical user per unit treated, or wire-to-water pump efficiency, or data used in a computerized works management system such as motor run times, bearing temperatures, or vibration for predictive driven maintenance. All calculations should be listed for integration in the controller or supervisory control system. Process data points that require static trending and generation of automatic reports should be identified for implementation by the programmer.
