Point attributes are dependent upon the configuration of your interface. Use the point attributes below to define the PI point configuration for the interface, and to identify the data you wish to transfer.
UniInt provides exception reporting, while Data Archive or PIBufss provides data compression. Both are important aspects of data collection and archiving.
Additional information on PI Point attributes and classes is available in the PI Server documentation, where you can identify your server version and view information point classes and attributes.
