Hmm...I didn't know that the priority did not come out on the printer. Not
really sure why this would be the case, as the Alarm Manager and legacy
historian know about it. Is this true of any non-AM alarm device?
To do long-term alarm logging, I have some scripts to read and parse the
almhist file that the legacy historian uses for a circular alarm history
buffer. These were based on some code I found on the Cassandra site and
in some Foxboro HH documents, but I've had to modify them several times as
I've come across weird data the historian puts in this file for certain
alarm types, and to add additional features (like putting the year in the
timestamp). It's not real-time (it runs out of cron every hour), but
suits my needs. I hope to get this into some kind of database (either my
own or some alarm-management product's) for better analysis capabilities.
As for how the alarm management vendors determine priority, most of the
packages I've seen also import part or all of the system configuration
(either periodically from iccprt dumps or live via OPC) and get the
priorities from that.
