27.2.1.1 Create and use Hub

 

WebAccess SignalR provides API interfaces that can be used to retrieve WebAccess data. Based on data categories, these API interfaces are split into 3 hubs as follows:

ØtagDataHub：Consists of API interfaces for tag information

ØwaDataHub：Consists of API interfaces for miscellaneous information

ØalarmDataHub：Consists of API interfaces for alarm information

 

.NET

var hubConnection = new HubConnection("http://localhost/WARTCommunication/signalr");

IHubProxy tagDataHubProxy = hubConnection.CreateHubProxy("tagDataHub");

JavaScript

$.connection.hub.url = "http://localhost/WARTCommunication/signalr"

$.connection.hub.start().done(init);

tagDataHubProxy = $.connection["tagDataHub"];
