PI calculation (page 248) data sets (including FactoryTalk Historian
expression and FactoryTalk Historian Summary data sets) from
FactoryTalk Historian Universal Data Server equations.

ODBC (page 254) (Open Database Connectivity) data sets obtained
from a relational database. ODBC client capability means that without
writing vendor-specific code, you can access data from certain
relational databases outside the FactoryTalk Historian system and
include that data in your FactoryTalk Historian ProcessBook displays.
The outside data source must be ODBC-compliant; for example, it
must provide an ODBC Driver. An outside ODBC data source might
include laboratory results, cost tables, or other sets of information that
can be obtained through SQL queries. Since access to ODBC sources
is configured on a particular computer, moving a display file that uses
an ODBC data set may require the data source to be configured on the
new computer. The data source has to have the same name on the new
computer, or the data set will need to be reconfigured in the display.

Custom (page 257) data sets built as COM objects supplied by Visual
Basic or C++ programs as Add-Ins to FactoryTalk Historian
ProcessBook. Custom data sets exist at the FactoryTalk Historian
ProcessBook application level, so they don't need to be defined for
each processbook or display. However, they do need to be installed on
any client machine where they are used.

PI Calculation Data Sets

PI Calculation Data Sets include FactoryTalk Historian Summary Data
Sets and FactoryTalk Historian expression Data Sets. These are drawn
from the FactoryTalk Historian server and plotted dynamically.

Use the PI Calculation dialog box to create, edit, or delete data sets. You
can select predetermined calculations or create your own expressions. A
similar dialog box is used to configure ODBC data sets (page 254).
