TD and PakBus Operating System Addendum for
CR510, CR10X, and CR23X Manuals
AD1 Major Differences
Table Data (TD) operating systems have two major differences from the
standard operating systems: First - the namesake - in the way data are
stored internally and second, in the options available for transferring
that data to external devices. The standard operating systems support
both on site external storage (i.e., storage modules) that may be
manually retrieved and telecommunications. The TD operating systems
have more advanced telecommunication and networking capabilities but
do not support storage modules. There are two versions of the TD
operating system: TD and PakBus. The PakBus operating system
includes the PakBus communications protocol that allows some
additional communications options (Section 12); other features are the
same as the TD operating system.
The datalogger hardware and direct measurement capabilities are the
same in either case.
Feature Table Data OS Standard OS
Internal Data Storage Multiple Data Tables, at least
one Table for each output
interval. One or two Final Storage Areas.
Data Arrays output at different
intervals may share the same area
and are identified by ID.
Term for a set of values output
together Record (a row of the table) Array
Term for individual values
within the array or record Field (a column of the table) Element
Number of elements or fields in
an array or record A fixed number, determined by
the program Generally fixed but conditional
elements possible. Determined
by program
