Hi Team,

I was going through the specifications & OPC-UA Portal Reporting Tool for A&E. There are many things which a client should have; to support this feature. I found some mandatory & optional services on Portal as well.

But, since there is no test case defined for A&E & have 1-2 lines of description for each services e.g., Monitor Client Events & Monitor Client Event Filter from Event Subscriber Client Facet. I was facing difficulties in understanding the actual expectation from an OPC client for A&E feature.

Could you please help me in understanding below thing in context of Events & A&C Facets:

  1. What all things I should follow ?
  2. What is expected by a client at minimal ?
  3. Is it required to have all types of events available in OPC Specifications, a client should allow to subscribe ?
  4. There was one more point which says, an OPC client should be able subscribe to base events. Does this means a client should be able to capture Status, Severity, EventId, EventType, Time & Message in addition to the custom event information ? What does base event means here ?

One more question I've, when we look at this from Profile perspective, in which profile Event & Alarm&Condition Facets belongs to ? 

 

Thank you

Dipika Khera,

  I was somewhat confused by the original post, A&E is a classic concept, In OPC UA it is Alarms and Conditions. Are you asking about the OPC Classic A&E client? Are you asking about the mapping of OPC Classic (A&E) to OPC UA (A&C) and testing for this mapping?  Or are you looking for information about an OPC UA Alarm & Condition Client?

[OPC Classic is fairly old DCOM based technology, OPC UA is the current service oriented architecture]
