A METHOD FOR DISPLAYING ENERGY-RELATED DATA ON A WORKSTATION OF A PROCESS CONTROL SYSTEM.

摘要

The invention is a method for displaying energy-related data on a workstation of a process control system upon receiving a request by a user. Energy-related measurement data is obtained which is dependent on a physical property of at least one apparatus in a process in a process plant monitored and controlled by the process control system. The method comprises displaying a graphical control object on a graphical user interface of the workstation connected to the process control system, detecting user input to the graphical control object as a request for energy-related data, displaying the energy-related data for the at least one apparatus as an overlay superimposed on or beside the at least one apparatus in the graphical user interface. Both the energy-related data and a part of the at least one apparatus are visible on the graphical user interface at the same time. In other aspects of the invention a workstation, system and a computer program for carrying out the method are described.
