  • Page 285 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 286 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).
  • Page 287 Edit the CSI file with a text editor (e.g., “Notepad” - Edlog will not allow you to make and save this change) and add –TD to the datalogger type on the first line, for example, change: ;{CR10X} ;{CR10X-TD}. Save the CSI file and close the editor.
  • Page 288 Section 5 TD operating system is different than that of the standard operating systems. Campbell Scientific provides software for communications; a description of the protocol is beyond the scope of this addendum. Many of the peripherals discussed in section 6 are not supported by Section 6 the TD operating system.
