Abstract
A program creation support program to display devices that store data indicating the operating status of a control system and associated device values, based on a control program executed by a control apparatus, causes a computer to perform a dependency relationship extraction step of extracting the dependency relationships between the devices described in the control program, a log data input step of acquiring, as log data information, log data collected by the control apparatus during the operation of the control system, based on recording setting information describing a condition for collecting the log data information, a display information generation step of generating display information that visualizes the dependency relationships and visualizes the device values associated with the devices, based on the dependency relationships and the log data information, and a generation result output step of displaying the display information.
