DEVELOPING ENVIRONMENT DEVICE FOR CONTROL PROGRAM, CONTROLLER EXECUTING CONTROL PROGRAM, AND RECORDING MEDIUM FOR PROGRAM ACTUALIZING THEM

摘要

PROBLEM TO BE SOLVED: To improve debugging efficiency and system customization and to secure programming easiness and the independency of control by describing a group of cycle tasks, refresh blocks, and event tasks, inputted as a control group, relatively to the control group. ;SOLUTION: On a program developing tool, the control group is defined. For example, three event tasks 1 to 3, two cycle tasks 1 and 2, and three refresh blocks 1 to 3 are defined for the control group 1. Further, three event tasks 1 to 3, one cycle task 10, and one refresh block 10 are defined as ones which do not belong to the control group. The control group is defined and then information is generated in a memory of a personal computer or on a storage medium such as a hard disk. Then 'cycle task names', 'refresh block names', and 'event task names' are related and stored by control groups.;COPYRIGHT: (C)2000,JPO
