PointSource
The PointSource is a unique, single or multi-character string that is used to identify the
Historian point as a point that belongs to a particular interface. For example, the string
Boiler1 may be used to identify points that belong to the MyInt Interface. To implement this,
the PointSource attribute would be set to
Boiler1 for every Historian Point that is
configured for the MyInt Interface. Then, if /ps=Boiler1 is used on the startup command-
line of the MyInt Interface, the interface will search the Historian Point Database upon startup
for every Historian point that is configured with a PointSource of
Boiler1. Before an
interface loads a point, the interface usually performs further checks by examining additional
Historian Point Attributes to determine whether a particular point is valid for the interface.
For additional information, see the
/ps parameter. If the PI API version being used is prior to
1.6.x or the Historian Server version is prior to 2.x, the Point Source is limited to a single
character unless the SDK is being used.
Case-sensitivity for PointSource Attribute
The PointSource character that is supplied with the /ps command-line parameter is not case
sensitive. That is, /ps=P and /ps=p are equivalent.
