Abstract

A period in which a series of pieces of processing is repeatedly performed is changed according to a situation in a control device. A control system including the control device that repeatedly performs the series of pieces of processing including I/O refresh processing and program execution processing in a first control period is provided. The control system includes: a first obtainment unit configured to obtain a first sample value group that is collected by repeatedly performing the I/O refresh processing in the first control period; a second obtainment unit configured to obtain a second sample value group that is collected when the I/O refresh processing is repeatedly performed in a second control period longer than the first control period; a determination unit configured to determine whether a first frequency component included in the first sample value group and a second frequency component included in the second sample value group are substantially identical to each other; and a change unit configured to change the first control period to the second control period under a condition that the first frequency component and the second frequency component are substantially identical to each other.
