Abstract

외부 통신장치의 통제기 접속유무 검출 방법에 있어서, 상기 통제기 접속에 따른 대기시간 각 변수를 초기화하고 초기 접속확인 메세지를 전송하고 상기에서 메세지 전송후 응답 대기신호를 설정하고 일정 시간 경과에 따라 송출대기시간, 이전송출 메세지 응답 및 무응답 대기시간을 증가시켜 제1차적으로 상기 무응답 대기시간 허용시간을 초과했는지 여부를 확인한다.In the method of detecting whether a controller is connected to an external communication device, the wait time according to the controller connection is initialized, an initial connection confirmation message is transmitted, a response wait signal is set after the message is transmitted, and a waiting time for transmission is set according to a predetermined time. In addition, the transmission and reception message response and non-response waiting time are increased to first check whether the non-response waiting time is allowed.

그리고 상기 무응답 대기설정 허용시간이 초과하지 않았을시 비접속 검출문장 화면을 송출하고 메세지 통신 송수신 기능을 억제하고 상기 무응답 대기 설정 허용 시간이 지나고 이전 송출 메세지 응답 대기 시간이 허용시간을 초과했는지를 체킹하여 상기 허용시간을 초과했을시 접속여부 경고 문장을 화면으로 송출하고 상기 송출대기 허용시간을 초과했을시를 체킹하여 지났을때 접속 확인 메세지를 송출하도록 되어 있다.When the non-response wait setting allowance time is not exceeded, the connectionless detection sentence screen is sent out, the message communication transmission / reception function is suppressed, and whether the non-response wait setting allowance time has passed and the previous transmission message response waiting time have exceeded the allowable time When the allowable time is exceeded, a connection warning message is sent out on the screen, and when the timed out waiting allowance is exceeded, the connection confirmation message is sent.
