The PI point is the basic building block for controlling data flow to and from the PI Server. A single point is configured for each measurement value that needs to be archived.
Point Attributes
Use the point attributes below to define the PI Point configuration for the Interface, including specifically what data to transfer.
Tag
A tag is a label or name for a point. Any tag name can be used in accordance to the normal PI point naming conventions.
Length
The length of the Tag field is limited by the version of the PI API, the version of the PI Server, and sometimes by a specific Interface. The table below explains this in more detail. When the maximum possible lengths differ for the software installed on site, the shortest length applies.
The PointSource is a unique single or multiple character string that is used to identify the PI point as a point that belongs to a particular interface. For additional information, see the /ps=x command-line parameter and the PointSource section.
