Abstract
A controller system includes a controller that executes a control operation in order to control a control target, and a security unit that is in charge of a security function for the controller system. The security unit includes a detector that detects a presence or absence of an incident regarding security in the controller system. The controller transitions a control mode to a degeneration mode when the detector detects the incident, and the controller maintains the control mode in the degeneration mode until cancellation of the incident is detected by the detector.
