MULTIPLE TASK HIGH SPEED EXECUTION APPARATUS IN THE PLC SYSTEM

摘要

PURPOSE: A high speed multi-task performance apparatus of a programmable logic control system is provided to perform the plurality of tasks by determining an order of performing the plurality of tasks inputted at the same time. CONSTITUTION: The high speed multi-task performance apparatus of a programmable logic control system includes a gate array(20) for performing a program written by a user at high speed. The user writes the program using a peripheral apparatus(10), and the program is stored in a memory(11). The gate array(20) reads or outputs data through the input and output part(14). A microprocessor(13) performs the calculation which is not performed by the gate array(20). A high speed inputting part(30) responses to an input from an exterior. The gate array determines an order of performing the plurality of tasks which are inputted at the same time.
