CONTROL SYSTEM, ANALYSIS METHOD, AND PROGRAM

Abrégé

In the present invention, a support device acquires: trajectory information in which the position, of a machine tool, corresponding to a command value generated by execution of an NC program is associated with time information that indicates a control time at which the command value has been used; and variable history information in which a variable value updated by execution of a sequence program is associated with time information indicating an update time. The support device selects a target period in the program execution period, displays, in a display device, a part corresponding to the target period in a trajectory indicated by the trajectory information, and displays, in the display device, the variable value in the target period on the basis of the variable history information.
