SYSTEM MONITORING APPARATUS AND CONTROL METHOD THEREOF

摘要

A system monitoring apparatus that provides a guide to reduction of energy consumption in a system, and a method for controlling the system monitoring apparatus. A screen illustrates information on the energy consumption in the production system before an energy saving measure. An upper graph of the screen illustrates a time change of electricity usage of a heater. A lower graph of the screen illustrates a time change of status data of the heater. In the lower graph, a difference between the status data and a lower limit is illustrated as extra energy.
