PURPOSE: An equipment control method using personal computer foundation's multi-tasking is disclosed to maximize the performance of controller, to provide coding's effectiveness by creating block unit's sequence and individually training device's parts, and to minimize development time by conducting tests without connecting sequence's hardware lever movements to actual equipment in PC. CONSTITUTION: An equipment control method using personal computer foundation's multi-tasking is composed of satisfaction and identification. A sequence block satisfies the implementation criteria, such as event, whole region variable, and messages, through the setting of each thread class's sequence operation events, such as SetEvent, Reset Event, and Pulse Event. Address number and segment ID are checked to see if identical to each other by using thread class or segment ID that is declared as an entire region variable or predetermined value of the block. A software and hardware's execution criteria lists are satisfied. An execution criteria list can be composed of inputed hardware variables or reversed variable values. An outsider's criteria can also be used to satisfy the criteria or dissatisfy the criteria to change the execution criteria.
