Synchronizing devices

Power Operation with Advanced Reporting and Dashboardsrequires a PO to PME ETL job to transfer device data logging from PO to the Power Monitoring Expert database. If devices change in PO, the ETL job does not automatically recognize the change and the two systems are no longer synchronized.

The following scenarios describe what happens to the integrated systems when you make changes to PO sources (after the initial PO to PME ETL job is configured and running):

Scenario: Adding devices in PO

When you add a device in PO, the source and its data are not automatically available in PME.

You must edit the ETL job to map the new device to PME and then run the ETL job. SeeEditing a PO to PME ETL job for details.

Scenario: Editing sources in PO

When you edit a device name or change the device's measurement logging in PO:

  • The old source name continues to exist in PME
  • If you edit the ETL job to include the new source name and then run the job, a new historical source (with the edited name) is created in PME and the source's logged data is associated with the new source name. However, the data that was logged before the source name change will continue to be associated with the old source name.

You must edit the ETL job to map the edited source name or measurement to PME and then run the ETL job. SeeEditing a PO to PME ETL job for details. You might also need to update the database to associate the historical source data with the edited source.

Scenario: Deleting a source in PO

When you delete a device in PO:

  • The old source name and its historical data continue to exist in Power Monitoring Expert
  • If you edit the ETL job to include the new source name and then run the job, a new historical source (with the edited name) is created in PME and the source's logged data is associated with the new source name. However, the data that was logged before the source name change will continue to be associated with the old source name.

You must edit the ETL job to remove deleted source from the ETL job and then run the ETL job. SeeEditing a PO to PME ETL job for details.

You might also need to update the database to associate the historical source data with the deleted source.

Scenario: Upgrading a source in PO

When you upgrade a source in PO, the data transfer for the source continues seamlessly as long as the Trend Tag Name and I/O Device Name remain the same. Even if the Communication Protocol or I/O Device Address changes the Variable Tag and the Trend Tag will remain unchanged.

Limitations

The following scenarios are not supported by the PO to PME ETL:

  • Moving a device from PO to PME
  • Viewing historical data from ETL sources in Vista or Diagrams in PME.

The following scenarios require that you to contact technical support:

  • Renaming an ETL source in PME.
  • Deleting an ETL source in PME
