EsayAEClient No Events
There is an issue, however, that due to vacation, between July 3 and July 10 no actual investigation/testing/development work can be done.
In order to find out precisely what is happening, unfortunately the Team Viewer would not be enough. We would need to be able to access the server through OPC A&E from our test/development computer, so that we can debug inside the client and see the responses of the server (there are tools to analyze the OPC DA communication, such as OPC Analyzer from OPC Foundation, but unfortunately not for OPC A&E).
Isn't there a way to obtain a demo version for test?
After checking in detail how the Refresh call (which most likely is not implemented in your OPC server) is handled, I have found that there are ways you can suppress its calling in QuickOPC, which should hopefully resolve this problem.
One way to do it is to specify RefreshWhenActive = false in the call to SubscribeEvents. Here is an example of how it may look like:
int handle = client.SubscribeEvents( new ServerDescriptor("", "OPCLabs.KitEventServer.2"), new AESubscriptionParameters(notificationRate:1000), refreshWhenActive:false, state:null);
Please try this.
Another way to achieve similar outcome is to exclude the condition events from the event filter.
We may still change the E_NOTIMPL handling of the Refresh() result, but because there are ways to work around it, it will only go into a subsequent QuickOPC version.
I will let you know here on the forums when this is available or when there is more information to this case.
It is Siemens Software(SiPass) for Acess Controll and have built in OPC AE event server. Server is on site and it have licence without internet connection. I can make hotspot from my phone and give you acess to server with TeamViewer if it is ok? If this is ok send me mail or call me to go on site to arange TeamViewer connection ?. My collegs told me that we have one other server with demo licens in company and they can put TeamViewer for testing(I did not testet on that) ?
Which OPC server are you using? (vendor, model)
Is there a trial version of it that we can test here?
We might be able to make the client part more "forgiving" and work even when something is not implemented on the server, but we need to analyze the OPC communication details first.
