Chapter 4 Using the Trend Recorder
Introduction
The following sections describe how to record, save, export, and print a trend. Once
recorded, the displayed trend can be viewed on the screen just as it would be printed,
or you can choose to print a hard copy.
Recording Trends
After you have added the signals to the trend, you must record the data to view the
trend on the graph.

From the View Menu, choose Record .
When you want to stop recording, choose Record again from the View menu, or
click the Record button again.
If the data cannot be viewed within the range you selected, you can either modify the
range using the Channel Configuration dialog box (refer to the section, Editing
Properties), or by choosing Auto Range Vert. Axis from the Edit menu.
Saving Trends
Trends can be saved to files for later replay and analysis. The files have the
extension .trn. If the trend is attached to a device when saved, the trend defaults to
the Trends sub-directory, under the directory of the device being trended. If the trend
is not attached to a device, such as a Data Historian collected or .dca file trend, the
trend defaults to the current working directory.
If you want to save just the setup that was recorded, this option must be chosen in the
Trend Recorder Configuration dialog box under Save Mode. (See the section,
Configuring the Trend.) The default for the Save Mode is Setup and Data. If you
save the setup and data, each data event is saved to files of the same name with
extensions starting at .000 and increasing.

Save Mode and click OK .
