How the Number of Data Points in Linked Files Is Calculated
This section explains how the number of data points in linked files is calculated.
Calculation Method When No Data Is Missing
When there have been no power outages or time changes, the number of data points is
calculated according to the data start and end numbers of each unit of data.
When there has been a time change, any time changes within connected files are ignored,
and the number of data points is calculated according to the data start and end numbers
of each unit of data. When there has been a power outage, blank data is inserted. The
number of inserted blank data points is determined by the following formula.

Saving the Link Settings File
The link settings are saved to the link settings file (the extension is .ldx). The procedure is
the same as the procedure to save display settings. See section 2.9, “Saving the Display
Settings.”
Displaying Linked Files
When you open an .ldx file, the linked files are displayed.
Note
Files with the extension .ldx contain only link settings. To reopen a linked file, you must have
the original data file.
