About events and event logging

This section describes IWS‘s logging and event-retrieval features. An event can be any tag change, generating reports or recipes, opening and closing screens, logging onto and logging off the security system, and so forth. IWS saves all of these events in a log file, which can then be retrieved by the Alarm/Event Control object.

  • Enabling the event logger
    Event logging is disabled by default, to conserve runtime resources. To enable the saving of events to the history file, use the Event Logger in the Project Explorer.
  • Saving your alarm history / event log to an external database
    By default, your project’s alarm history and event log are saved to proprietary-format text files in your project’s Alarms folder. However, you can change your project settings to save them to an external SQL database instead.
  • Format of the event log
    The location and format of the event log depends on whether History Format is set to Proprietary or Database. This section describes both.
