Status displays the current Data Transfer status (Running or Stopped). If necessary,
click [Start] or [Stopped] to start or stop Data Transfer.
Enable Auto Transfer
Auto Transfer is disabled by default. If you change to AutoTransfer mode and then
click the Enable Auto Transfer checkbox, this provides immediate Data Transfer.
Clicking [Save] is not required. If AutoTransfer has previously been checked and you
now uncheck it, points that were previously transferred will continue to be
transferred, but new points must be added manually.
If you attempt to transfer points and the FactoryTalk Historian SE or PI server is not
licensed to receive the points, a message will be sent to the system log indicating this
and stating that the data transfer mode has been changed to non-auto transfer
mode.The configuration then switches to non-auto transfer mode, and you must
manually transfer points by selecting them one-by-one.
If the Data Transfer service is in Auto Transfer mode after points have been created,
it may continue running. If Auto Transfer mode is not enabled, you must manually
select points to transfer and restart Data Transfer.
Viewing Data Transfer Statistics
The Data Transfer service records performance statistics that determine the
connection reliability. These statistics can be used to refine the settings in the
Configuration service.

Transfer Rate - number of retrieved events divided by the number of minutes
spent retrieving events sent to the FactoryTalk Historian SE or PI server.
„
Successful Attempt Rate - number of attempts to transfer data to the FactoryTalk
Historian SE or PI server per hour.
