PtClassName

PtClassName specifies the point class. The point class must be defined before the point is created.

The default PI point classes are:

• Alarm

  Used for alarms.

• Base

  A common set of attributes that all point classes include. The Base class includes both system-assigned and user-assigned attributes.

• Classic

  Includes attributes used by interfaces. Points that represent data from a PI interface are always in the Classic point class.

• SQC_Alarm

  Used for SQC alarm points.

• Totalizer

  Used for points that represent a running total of data. For more information on Totalizer points, see the information on the Totalizer tool in the PI System Management Tools guide.

In some cases, you can edit point classes. For details, see Modification of PI point classes.
