Control system, control program, and control method for device switching responsive to abnormality detection

A non-transitory computer-readable storage medium storing a control program executable by a computer to implement a controller for controlling a control target, the program causing the computer to perform operations comprising:

• generating a feature quantity from data associated with redundant devices accessible from the controller;
• determining whether an abnormality has occurred in one of the redundant devices based on the generated feature quantity and a predetermined abnormality detection parameter;
• switching the redundant devices between a working mode and a standby mode in response to the abnormality being determined to have occurred;
• and
• performing machine learning using the data associated with the redundant devices to determine the abnormality detection parameter.

A control method used by a controller for controlling a control target, the method comprising:

• determining whether an abnormality has occurred in one of the redundant devices based on the generated feature quantity and a predetermined abnormality detection parameter;
• switching the redundant devices between a working mode and a standby mode in response to the abnormality being determined to have occurred;
