Abstract

본 발명은 PLC본체측에서 프로그램에 의해 고유 메모리를 통하여 위치 결정 운전을 할 수 있는 공유 메모리를 이용한 위치 결정 운전방법에 관한 것으로, 일반적으로 PLC의 위치 결정 운전은 별도의 프로그래밍 장치를 이용하여 위치 결정을 행하는 속도, 위치, 시간 파라미터를 입력하게 되어 있어, 위치 결정 운전을 하기 위해서는 별도의 주변 장치들이 반드시 필요하게 되며, 이러한 주변장치가 없으면 실제적인 위치 결정이 불가능했다.The present invention relates to a positioning operation method using a shared memory that can perform a positioning operation through a unique memory by a program on the PLC main body side. Since the speed, position, and time parameters for performing the operation are inputted, separate peripheral devices are necessary to perform the positioning operation. Without such peripheral devices, actual positioning was impossible.

이러한 문제점을 감안하여, 위치 결정 유니트 내부의 인터 페이스부와 연결된 공유 메모리를 이용함으로써, 별도의 주변장치가 없어도 위치 결정 운전 정보의 전송이 가능하게 된다.In view of these problems, by using a shared memory connected to the interface unit inside the positioning unit, it is possible to transmit the positioning operation information without a separate peripheral device.

Claims (1)

위치 결정 유니트(4)에 있는 공유 메모리(9)의 사용 가능 여부를 판별하여 사용 가능시 공유 메모리(9)에 기입된 정보를 위치 결정 정보 기입용 메모리(12)로 전송한 후 공유 메모리 사용권리를 양보하여 PLC본체의 CPU(2)에서 위치 결정 정보 기입용 메모리(12)의 정보를 기준으로 위치 결정 운진을 실행하는 것을 특징으로 하는 공유 메모리를 이용한 위치 결정 운전방법.Determine whether the shared memory 9 in the positioning unit 4 is usable or not, transfer information written in the shared memory 9 to the memory 12 for positioning information writing when available, and then use the shared memory right. And positioning operation on the basis of the information of the positioning information writing memory (12) in the CPU (2) of the PLC main body. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
