  • Page 201 TABLE DATA ADDENDUM 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.
  • Page 202 TABLE DATA ADDENDUM AD2 Overview of Data Storage Tables Within a data table, data is organized in records and fields. Each row in a table represents a record and each column represents a field. To understand the concept of tables it may be helpful to consider an example. A CR10-TD is to be used to monitor 3 thermocouples (TC).
