File combination
On the DX Series, the display data file and event file can be combined in the following manner to
suite the application.
1. Display data file + event file (ROTATE)
When you wish to analyze the long-term trend as well as the data around the point at which the
external recording medium is inserted.
2. Display data file + event file (TRIG)
When you wish to analyze the long-term trend as well as the data around multiple trigger points
that are set off by alarms and contacts.
3. Display data file only
When you wish to continuously record over a long period.

When you do not need the long-term trend that is stored using a slow sampling interval. Instead,
you want to store as much data as possible at a high sampling interval.
