摘要
PROBLEM TO BE SOLVED: To shorten the time necessary for task switching and to improve the processing speed of a programmable controller. ;SOLUTION: When the tasks X1 to Xn receive the start instructions (a) from a system program SP (S3), these tasks start execution of their processing. Then every task carries on its processing until the information to be saved does not exist when a stop instruction (b) is received after a prescribed time T (S4). When no information to be saved exists, the task execution is stopped and a task request (c) is outputted to a system program SP (S5). The program SP instructs the start of the next task when the request (c) is received from one of tasks X1 to Xn that received the instruction (b) (S6, S2).;COPYRIGHT: (C)1997,JPO
