Abstract

PURPOSE: To increase the execution speed by the execution of instructions of programmable logic control unit only with the pre-processing, corresponding step and post-processing.
CONSTITUTION: In the step sequence control using the programmable logic control system of sequential execution type, the step sequence program 1 has the step processings 41...4i between the pre-processing section 2 and the post-processing section 3. Further, the control unit is operated by referencing the program entry pointer 5 pointing the first part of the program, execution step entry pointer 6 pointing the first execution instruction of the step under execution, and post-processing entry pointer 7 pointing the head address of post-processing. Thus, the execution of the instructions of the unit is limited only to the pre-processing, corresponding step and post-processing to enable to increase the execution speed.
