OPC Event Attributes to 3rd Party Interface
Hi,
I am wondering if there is a way to select which OPC Alarm & Event attributes are collected. For instance, I would like to be able to see the message field to populate at the 3rd party server as well as prioritylevel, etc. Is there a way to include more information that just what is standard and to pick and choose which attributes are collected?
Thanks,
Mike

OPC AE attributes are split in two categories: standard (e.g. SourceName, Condition, Message, Severity) and vendor (e.g. SourceGUID)
A third party OPC AE client collecting events from 800xA will receive both standard + vendor attributes, but I cannot tell if your choice of client support all attribute categories/types.
- System 800xA collect both categories of attributes from its configured sources
(I cannot tell if all exotic attributes datatypes like variants and arrays are fully supported, probably not) - System 800xA alarm and event lists may be configured to present any attribute (standard + vendor) with the exception of not supported datatypes (variants, arrays, etc).

Hi Mike,
There is a lot of attributes on each event so you may consider a way to exclude certain events you don't want to analyze.....
Depending of your third party client, filter can be created to exclude events and attributes to keep down the load.
