Transferring Data
This chapter contains the following sections:
“Selecting Points to Transfer”
Transferring Data Overview
The Data Transfer service works with the Data Storage and Data Collection services
to transfer historical data to a FactoryTalk Historian Site Edition (SE) or PI server
(available from OSIsoft). The Data Transfer service can only transfer data to one
FactoryTalk Historian SE or PI server at a time. Before you transfer data from
FactoryTalk Historian ME to a FactoryTalk Historian SE or PI server, make sure that
the server has an archive that covers the data time period you have in FactoryTalk
Historian ME. You may need to create an archive for the FactoryTalk Historian SE or
PI server that covers this time period.
Connecting to a FactoryTalk Historian SE or PI Server
The Data Transfer service gets information from the Configuration service for the
designated server and makes the connection.
Please note that if the connection between FactoryTalk Historian ME and the
FactoryTalk Historian SE or PI server is lost, it will take some time for the data to
synchronize.
Uploading Historical Data
Any data left over from the previous shutdown of the FactoryTalk Historian ME
system that was not transferred to the FactoryTalk Historian SE or PI server is
transferred when Data Transfer is restarted. The time stamp in the Point ID mapping
table determines what data needs to be transferred.
See the FactoryTalk Historian SE System Management Tools (SMT) online help for
information about FactoryTalk Historian SE. For information about the PI server, please
refer to OSIsoft’s documentation.
