6.3 Archive File Types
Archive files are created in one of two user-selectable formats:
Text (comma separated values [.csv]) – see Section 6.4, page 54 or
Secure binary encoded – see Section 6.5, page 59
All archive files created by the recorder are given filenames automatically but each type of archived file is given a different file extension depending on whether Text or Binary format has been selected during archive configuration – see Section 7.7.4, page 90.
