Application
Unicode text file format
This is a file format which can be open in generic-purpose application programs such as Excel and Notepad. GX LogViewer is
also available for displaying data.
Binary file format
Comparing the Unicode text file format, the size of files is small and therefore quicker access to files is provided. GX LogViewer
is also available for displaying data.

Select an SD memory card or the function memory for the storage location. ( Page 966 Logging type)
The number of data logging settings and the number of records vary, depending on the storage location. For details, refer to
