Chapter 5 Viewing Trends
Introduction
An event is a set of data
recorded without
interruption. When the Trend Recorder is not recording or uploading data, it is in replay mode. In
replay mode there can be multiple events stored in the trend.
•
For real-time continuous recording, there is an event each time the Record
mode is chosen.
•
For real-time triggered recording, there is an event each time the trigger
condition is satisfied.
•
For block-collected recording, there is an event for every upload that occurs.
•
In Data Historian and .dca file trends, all data is maintained in a single
continuous event (only one event).
