How to configure Alarm Line to show both types alarms of particular AC450 Process section /particular AC800M Class

Dear 800xA specialists,
I need to configure Alarm Line to be able to show alarms from 2 sources in the same moment:
- from AC450 filtered by particular Process section
- from AC800M filtered by particular Class number

After some try and error it seems to me that Area/Process Section has lower priority than Area/Class filter in Alarm Configuration.
If both Process Section and Class filters are set then I am getting just AC800M alarms in Alarm line.

I will be thankful for any idea.
Kamil

Alarm and events from AC 800M lacks the ProcessSection vendor attribute. This causes the filter to not include any events from such categories.

You may ask why having a "negative void coefficient" is right or wrong - I guess if it was positive, others would complain over seeing too much?

The good thing is that you can add any attribute to any alarm/event and give it any value using the Event Attribute Object Extension function. The attribute can be defined on one location and be inherited by all descendants, or be defined on "tree, branch, twig or leaf" level.

The standard documentation is not very good at describing how you add extensions, but I have linked to a 10 year old product bulletin several times here on AKS - searching the past years should give you several matches. This bulletin describe a problem that may arise from incorrect use of EAOE and the Appendix contain a complete A-B-C how to do it, and there is no arbitrary choice I took when supplying the author of the bulletin with the ProcessSection problem as an example.

The bulletin is:

Stefan, thank you for inspirational answer ! Honestly I don't dare to go ahead in the production system. Sure I will try Event Attribute Object extension in in the test system for future projects.
I just think about to use Class terminal of AC450 DB objects, I never used that before. Do you think can be Class used in both system types as common Area filter criteria?

Sure class will work.
Don't be afraid of using EAOE, if you get hold of the bulleting, use the custom made example in Appendix A and it WILL work. Send me an email, first.last(a)se.abb.com if you can't get hold of the bulletin.

@kamil. I've used this solution several times. It's quick, clean and easy.

the only thing wrong (as Stefan says) is that the documentation is *****

I followed Tor's solution below that is pretty quick but not that clean as EAOE.
Regarding EAOE it is not clear for me how to set distinct default values of extended Process section attribute for each AC800M CPU in the system.

The second half of the aforementioned 10 year old bulletin explain how to set a ProcessSection value on a parent object affecting a large number of descendants.

If you want to have different ProcessSection values among your AC 800M objects, you must create additional declarations - e.g. one on top of each application or hardware unit.

Really this is no more complex than creating a Log Summary aspect to count and manage logs on descendant objects.

Ultimately, you create one on each object where BDM might come in use.

However, if you have a handful of applications in need of an equal amount of ProcessSection values, you only need to create a handful of declarations, each on a common parent to the objects you want to have a given value of ProcessSection.

Off topic: The text "Event Attribute Object Extension" appear 26 times in three different user's guides of the 800xA v6.1 documentation set. I may have missed one or two documents since there seem to always exist stray user's guides outside the release media. E.g. 6.1 did not carry any Safety documentation in its initial release.

I personally maintain a collection of custom search indexes using Adobe Professional quickly accessible via links at the desktop/system tray of my computer.

The problem, none of those pages tell you exactly how to add ProcessSection to the Process Condition Event category of the AC 800M alarm collection definition. Instead of just saying "Make declaration here" and "here" (actually only two aspects need to be created and set appropriate to have ALL events of any category to carry a custom vendor attribute) the text quickly enter the topic of using bulk tools. Looking at Bulk Data Manager is crazy if you need to declare a common value for all objects of a certain connectivity. The two figures (2.31 and 2.32) on page 86 of the 6.1 Configuration User's Guide, 3BDS011222-610 A is all you need to read/comprehend.

The best documentation we have at hand given the OP's question is the aforementioned Product Bulletin.
