ABSTRACT:
A facility control monitor method and a facility control monitor apparatus capable of visually tracing a control logic and easily finding a cause of an operation trouble caused by the control logic. The facility control monitor method monitors control performed by a control device included in a facility having a controllable device, the control device for controlling the controllable device, a setting device for transmitting a setting control value to the control device, and a sensor for transmitting an operation state measurement value of the controllable device to the control device. Processes of control performed by the control device are stored. When an arbitrary date and time is specified by a trace controller (35), predetermined control steps of the specified date and time and after are displayed in a flowchart on a control flow display unit.
