Common alarm line for multiple alarm list
I've multiple alarm list in different project under different control network and also there're OPC link to S7, I've separate alarm list for all of these. Alarm line on operator workspace displays alarms from specific, is there a way to get alarms from OPC link to S7 also be merged with that. OPC is configured under OPC generic network in CS.
At the moment OPC alarm list is called by alarm band
There should be no problems merging alarms from different vendors into the same alarm list.
The solution depends on if you are making use of a locked/protected library or not.
Without a protected library you can do as follows:
1) Create a copy of the Common Alarm List filter (or any filter of your choice) in the Library Structure and give it a useful name.
2) On the filter settings, include the alarm categories you would like to see in the list (each vendor will have a unique category - use Event Details... window to tell what category an alarm or event has).
3) Change your alarm lists to use the new filter
With protected libraries you can not easily change the filter name (step 3 above) so you will have to perform 2) on the standard filters coming with the library.
There might be some middle-way I have not mentioned, but in any case keep a good record of what you change, especially if you have to alter any of the default alarm list filters since the settings might get lost and need to be applied again if you upgrade the system.
Answer to comment in my first answer:
There exists many many ways to filter alarms and events.
To filter on object location; "Objects and Descendants" is one option.
Another option is to use an Attribute Filter for the (Event Collector) Service Group ID.
The above makes it possible to include/exclude a whole event collector service group; however, since all alarm expressions are made from one OPC AE server, you can only include/exclude all expressions. So in this case, I think you need to skip this particular option.
A third option would be to use another attribute to filter on.
Remember that you can add own custom "fake" attributes using the Event Attribute Object Extension feature. This AKS thread have more info on this: http://www402.abbext.com/How-add-custom-columns-Alarm-Event-Logger-Configuratio
