Appendix B. Campbell Scientific File
Formats
Campbell Scientific, Inc. uses different formats for data in datalogger memory, external PC
cards, datalogger communication software, and PC files. The data formats written to PC
files by LoggerNet are written by default as .DAT files. The following sections will focus
on the format of these PC files, discuss the data formats that exist in the datalogger and on
PC cards, and describe methods for converting binary data formats.
B.1 PC File Data Formats
The type of data file generated by LoggerNet depends on the type of datalogger
from which data are being collected. Mixed-array dataloggers such as the
CR10X include the option to output comma separated files, ASCII printable
files, and binary files. Data from table-data dataloggers are output as ASCII
table files with no header, TOACI1 files, TOA5 files, TOB1 binary files, Array
Compatible CSV files, or CSIXML files. Data from PC cards (generated using
the CRBasic CardOut instruction) are output as TOB2 or TOB3 binary format.
B.1.1 Comma Separated
This file format describes values that are separated with a simple comma. Also
known as comma-delimited files, this data file format has the following
features:
•
Data from multiple arrays or intervals can be included in the same file.
•
Data are formatted in as little space as possible. Values are printed with
all extraneous formatting such as that used in the printable ASCII format
removed.
•
Commas separate all values.
An example of a comma separated file:
