Controller, time chart creation apparatus, and computer-readable information storage medium

A controlling method to control a device comprising a servo axis based on a time chart, comprising:

• outputting a control signal serving as a signal for controlling an operation of the device based on a description for controlling the operation of the device included in the time chart;
• counting an internal time corresponding to a time on a time axis of the time chart;
• and
• stopping, for at least one device as the device, the counting of the internal time until an operation of the at least one device is finished when the operation of the at least one device has not been finished after a scheduled finish time point of the operation of the at least one device on the time chart.
