The following parameters can be configured on the General PI ICU tab shown below:

Point source
The point source is used to identify points for this interface and is a required parameter. The point source that is assigned with this parameter corresponds to the pointsource attribute of individual PI points. The interface will attempt to load only those PI points with the appropriate point source.
Host
This is the PI Data Archive node. Select the PI Data Archive from the drop down list. If the server is not listed in the drop down list, use the triple dot button to browse to the Connections Dialog and add the server. The added server will then be available in the drop down list. (/HOST=hostname[:port])
Interface ID #
This required parameter is an integer that is used to identify a particular copy of an interface. The ID should match the value in Location 1 of points for this copy of the interface. This identifier is also added to the header that is used to identify error messages as belonging to a particular interface. (/ID=#)
