800xA Event Count via OPC
I need to collect certain alarm information via an OPC client from 800xA on a periodic basis; every minute. Some of the information is available via an alarm list's OPC properties, such as the IsAlarm property for the number of active alarms in an alarm list. But I also need to get a count of new alarms in the past minute (for several alarm lists); I set up a filtered event list to show this, but apparently event lists do not have OPC properties that can be read?
I think I can accomplish what I need using Alarm Analysis, but I would need to create several Alarm Analysis service providers to report every minute, for several different alarm lists. Is this too much? Is there another way of getting this information real time (not running a report)?
Thanks.
