Hi, I'm running 2 apps in a Windows Server 2012 R2.
The first app is a Windows forms that reads 20 tags (with Quick OPC version 2017.1) from a local Beanair Opc server. This app works using subscriptions and works fine without any problem.
The second app is a ASP.net MVC application that reads the same 20 tags (with Quick OPC version 2017.1) from the same local Beanair Opc server using signal R. When I run the app in the IIS Server the subscriptions don't give any kind of results.
When I run the same app in my laptop (Windows 8 ) the subscriptions returns the results with no problem. So I need to determinate wich is my problem (could be signal r or other libraries). Using Suscribe multiple I don't catch any kind of exception (recommendations in your documentation), but there a way (exception or code) to determine if the declaration of the subscription or parameters are not working well? for example in this code.
EasyDAClient humSuscrp = new EasyDAClient();
humSuscrp.ItemChanged += new OpcLabs.EasyOpc.DataAccess.EasyDAItemChangedEventHandler(humSuscrp_ItemChanged);
var humArray = new DAItemGroupArguments[4];
humArray[0] = new DAItemGroupArguments("", "Beanair.BeanOpc.1.0", "GATEWAY_3900.DEVICE_390000158D00000E0CCB.SENSOR_0", 1000, true);
humArray[1] = new DAItemGroupArguments("", "Beanair.BeanOpc.1.0", "GATEWAY_3900.DEVICE_390000158D00000E0CC6.SENSOR_0", 1000, true);
humArray[2] = new DAItemGroupArguments("", "Beanair.BeanOpc.1.0", "GATEWAY_3900.DEVICE_390000158D00000E0D1E.SENSOR_0", 1000, true);
humArray[3] = new DAItemGroupArguments("", "Beanair.BeanOpc.1.0", "GATEWAY_3900.DEVICE_390000158D00000E0B73.SENSOR_0", 1000, true);
humSuscrp.SubscribeMultipleItems(humArray);
Thanks and regards.
