node-opcua "트랜잭션 시간 초과"

Question

node-opcua 패키지를 사용하여 몇 개의 nodeIds에 대한 설정 모니터링이 있습니다. 잠시 동안 제대로 작동하지만 시간 초과 메시지가 인쇄되기 시작했습니다.

여기 내 서비스의 journalctl 출력입니다 :

은 기본적으로 영원히가는 모니터링을 유지하고는 15 분마다 발행 싶어. 누군가가 저를위한 매개 변수를 도울 수 있다면 정말 좋을 것입니다.

Answer 1

서버에 액세스 할 수있는 사람은 post입니다. 그들은 당신이 당신의 클라이언트를 설정할 때 그 국가 포스트에서

는 requestedLifetimeCount * requestedPublishingInterval은 적어도 PublishRequest.RequestHeader.timeoutHint로 설정되어야한다

var options = { 
 
    requestedPublishingInterval: 1000, // check on server 
 
    requestedMaxKeepAliveCount: 2, 
 
    requestedLifetimeCount: 100, // check on server 
 
    maxNotificationsPerPublish: 10, 
 
    publishingEnabled: true, 
 
    priority: 10, 
 
} 
 

 
var subscription = new opcua.ClientSubscription(opcSession, options);
