Hello.

Where are you seeing the error? In the Exception property of the EasyUAEventNotificationEventArgs in the event handler?

Regards

Yes, if I don't define the UAAttributeFieldCollection it works well, it receives the base event fields, but once I add UAAttributeFieldCollection argument, it gives errors.

Thanks! Checked it now.

Somehow I'm getting

~Bad_SessionClosed 0x80260000 The session was closed by the client.~

Error.

I will try now without the UAAttributeFieldCollection definition, it used to work like this before for base event data.

Hello,

I suppose this is what you are looking for - the Select clauses: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ml#The%20Select%20clauses.html .

Best regards

Hello dear experts,

I am using EasyUAClient to subscribe for server events but it is missing a lot of custom data fields PCS7 sends in the event. See the screenshot attached.

How do I enable them to be received with the event on opcClient.SubscribeEvent(...) method?

I tried opcClient.Enable(...) method to enable ConditionType but I am getting exceptions. Notice that UAExpert client can enable them and receive plenty of custom data. Now my task is to do same grammatically but seems like I am stuck

I'd appreciate an expert advice here. Thanks!
