SAFETY CONTROL DEVICE AND SAFETY CONTROL METHOD

摘要

Upon occurrence of an abnormality, a safety control can be executed more rapidly. An OS 100 partially includes a partition scheduler 21 that selects and decides a time partition to be subsequently scheduled according to a scheduling pattern including TP1 in which an execution time is allocated to a safety monitoring program, TP2 in which the execution time is allocated to a normal control program, and TP3 in which the execution time is allocated to a safety control program. A processor executes the OS 100 to cause the partition scheduler 21 to periodically operate. The partition scheduler is activated upon detection of an abnormality by one of the safety monitoring program executed in TP1 and the normal control program executed in TP2, and switches the time partition from TP1 or TP2 to TP3.
