[Alarm Summary] How long can save alarms ?

From the time I started work with Citect in 2010 I remember in Wizard was a parameter "Summary length" in rows (how much alarm can be in Summary? for example we set 10 000, 10 001 alarm will replace the oldest) but in production we want to save alarms in time period ( 3 months or 2 years).

By the reason we didn't use Summary

We used (and using right now) alarm log on web technology: apache + php + SQLite (via ODBC)/ We call it ALARM LOG. At the alarm log page we use an ActiveX element Microsoft Web Browser to display alarms fron our archive/log.

QUESTION: Does Citect in 2019 have any build-in instrument to log/archive alarms for configured period (for example 3 months or 2 years)?

In Citect 2015 help I don't see any descriptions about alarm summary ...... but in Citect 7.1 I remember it was .....

  • I talk about Citect 7.50 but in the next project we plan to use Citect 2018 and we have to know how alarms stored for retrospective analyse, which tools to display stored alarms has newest Citect versions.

    Our web-based alarm log has some defects (you must to do additional software installations, to do their configurations, sometime it stops to work and etc.) and we looking for built-in tools to archive alarms and to display archived alarms (with filtering and exporting to a file)
