The present invention relates to time partitioning to prevent a failure of processing while suppressing execution delay of interrupt processing even when the interrupt processing is executed. A safety controller includes: a processor; a system program for controlling allocation of an execution time of the processor to a safety-related task, a non-safety-related task, and an interrupt processing task; and an interrupt handler. Upon generation of an interrupt, the processor executes the interrupt handler to reserve execution of the interrupt processing task as an execution reserved task, and executes the system program to schedule the tasks in accordance with scheduling information on a safety-related TP to which the safety-related task belongs, a non-safety-related TP to which the non-safety-related task belongs, and a reservation execution TP to which the execution reserved task belongs. When execution of a task in a previous TP is finished before the period of the previous TP prior to the execution reservation TP has expired, the execution time in the previous TP is allocated to the execution reserved task.
