Reserved attribute names

PI DataLink automatically generates some virtual attributes for events and uses reserved names to identify these virtual attributes. To prevent conflicts with event-defined attributes, do not define events that use the following reserved names as attribute names:

• Acknowledged by

• Acknowledged date

• Annotations

• Duration

• Element template

• End time

• Event categories

• Event name

• Event path

• Event template

• Is acknowledged
