PURPOSE:To improve the economization of a stored program control system by accepting a restart request to register the start source task processing part, which requests the restart, to a queue of an execution priority added to the restart request. CONSTITUTION:Transaction memories 6 (6-1-6-30) corresponding to restart requests from a start source task processing part 1 are registered to a queue 7-2 corresponding to an execution priority B2 (the same execution priority) of task processing parts 2-1-2-5 to be started. Therefore, 25 transaction memories 6 registered in the queue 7-2 are all released by the first - the fifth start requests from the task processing part 1 to task processing parts 2-1-2-5. Thereafter, the task processing part 1 is restarted and can receive the registration end for the tenth and preceding start requests of task processing parts 2-1-2-5. |
