摘要： A safety control apparatus includes: control means that controls a control object; control monitoring means that monitors the control means, and upon determination that the control means is abnormal, outputs an abnormal signal; delay means that generates a delay signal and outputs the delay signal, the delay signal being obtained by delaying the abnormal signal output from the control monitoring means for a predetermined period of time; and stop means that stops the control object according to the delay signal output from the delay means. The control monitoring means may output the abnormal signal of pulse form to the delay means upon determination that the control means is abnormal, and the delay means may output the delay signal with pulse interval wider than that of the abnormal signal.

摘要： Time partitions which need not be executed can be skipped. An OS partially includes a partition scheduler which selects and decides a time partition to be subsequently scheduled in accordance with 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 TP 3 in which the execution time is allocated to a safety control program. A processor executes the OS to cause the partition scheduler to periodically operate. The partition scheduler skips a TP including a program which need not be executed among TPs included in the scheduling pattern, in response to a notification of an execution result from a program executed in at least one of the time partitions TP1 to TP3.

摘要： 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.

摘要： Upon occurrence of an abnormality, a safety control can be executed more rapidly. An OS partially includes a partition scheduler 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 to cause the partition scheduler 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.
