As en example, let's configure the driver to poll for Periodic and Daily History and disable Alarms and Events. This can be done in two ways:
The first way to do it is to configure scan rates as shown below:
- Alarm Scan Rate
- Set to -1 to disable polling for Alarms. If Alarms are not needed it is the best to set the 'Alarm Scan Rate' to -1. WIth 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 or on notification from the RecordInfoPoller.
- Event Scan rate Rate
- Set Set to -1 to disable polling for Events.
- If the 'Record Info Scan Rate' is set to -1, the 'Event Scan Rate' can be set to 0. With this setup, the EventPoller will not run on it own or on notification from the RecordInfoPoller.
- Periodic History Scan Rate
- Set to a positive number to launch the PeriodicHistoryPoller with specified poll rate
- Daily Daily History Scan Rate
- Set to a positive number to launch the DailyHistoryPoller with specified poll rate
- Record Info Scan Rate
- Set to -1 to disable the RecordInfoPoller so that there will be no notifications to Alarm, Events or and History pollers on any 'RecordInfo' change such as 'Last Record Sequence number Used', etc.
The second way to do it is to configure scan rates as shown below:
- Alarm Scan Rate
- Set to -1 Polling to disable polling for Alarms is disabled.
- Event Scan rate rate
- Set to -1 Polling to disable polling for Events is disabled.
- Periodic History Scan Rate
- Set to 0 Scan to poll on notification form the the 'Record Info' poller.
Daily - Daily History Scan Rate
- Set to 0 Scan to poll on notification form the 'Record Info' poller.
- Record Info Scan Rate
- Needs to be set Set to a positive number to poll Totalflow registers for any changes of Alarms, Events, and History arrays and notify History Pollers that there are new entries in Array 250 (LOG_PERIOD_RECORD) and/or Array 251 (DAILY_RECORD)launch the RecordInfoPoller with specified poll rate. With this setup, Periodic and Daily History pollers 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 history data at the rate specified in the EFM ABB Totalflow device configuration.
