As en example, let's configure the driver to poll for Event records and disable polling for Alarms and History. This can be done in two ways:

...

  • Alarm Scan Rate
    • Set to -1 to disable polling for Alarms.  If Alarms are not needed, it is the best practice to set the 'Alarm Scan Rate' to -1. With this setup, alarm records are not going to be pushed to the rs_efm_meter_alarm database table regardless of the alarm source setting (i.e. PERIODIC_HISTORY or ALARM_LOG_RECORDS).
    • If the 'Alarm Source' is set to the 'ALARM_LOG_RECORDS' and the 'Record Info Scan Rate' is set to -1, the 'Alarm Scan Rate' can be set to 0. With this setup, the AlarmPoller will not run on it own nor will it poll on notifications from the RecordInfoPoller. 
  • Event Scan rate
    • Set to a positive number to launch the EventPoller with specified poll rate.
  • Periodic History Scan Rate
    • Set to -1 to disable polling for Periodic History records.
    • If the 'Record Info Scan Rate' is set to -1, the 'Periodic History Scan Rate' can be set to 0. With this setup, the PeriodicHistoryPoller will not run on it own nor will it poll on notifications from the RecordInfoPoller. 
  • Daily History Scan Rate
    • Set to -1 to disable polling for Daily History records.
    • If the 'Record Info Scan Rate' is set to -1, the 'Daily History Scan Rate' can be set to 0. With this setup, the DailyHistoryPoller will not run on it own nor will it poll on notifications from the RecordInfoPoller. 
  • Record Info Scan Rate
    • Set to -1 to disable the RecordInfoPoller so that there will be no notifications to Alarm, Events and History pollers on any 'RecordInfo' change such as 'Last Record Sequence number Used', etc.

...

  • Alarm Scan Rate
    • Set to -1 to disable polling for Alarms.
  • Event Scan rate 
    •  0 Scan on notification form the  'Record Info' poller.
  • Periodic History Scan Rate
    • Set to -1 to disable polling for Periodic History records.
  • Daily History Scan Rate
    • Set to -1 to disable polling for Daily History records.
  • Record Info Scan Rate
    • Set to a positive number to launch the RecordInfoPoller with specified poll rate. With this setup, EventPoller will be notified on any 'RecordInfo' change such as 'Last Record Sequence number Used', etc.

At this point, the EFM ABB Totalflow driver is configured and is polling for Events at the rate specified in the EFM ABB Totalflow device configuration.
