Program Association

A table-based datalogger maintains final storage table information internally — this is referred to as the datalogger’s table definitions. The LoggerNet server uses this information for the Add dialog box when you select values to view on a Numeric or Graphical display.

Mixed-array dataloggers do not store final storage information internally. However, this information is contained in the *.dld file as commented text. When you download a program to a datalogger, LoggerNet uses the input location and final storage information from this file. If you communicate with a datalogger that already has a program in it, you can use the Datalogger > Associate Program option to select a *.dld file from which LoggerNet should get this information. A program file can also be associated with a datalogger from the Setup Screen’s Program tab.

Programs created with Edlog version 2.0 and greater include both the input location information and the final storage information in the *.dld file. Previous versions of Edlog stored only the input location information in the *.dld. If final storage information is not available for viewing in LoggerNet after associating the file, you may need to recompile the program file with a version of Edlog that stores this information in the *.dld file.

NOTE: If you are using Edlog Version 2.0 or greater and labels are still not available for use, check Edlog’s Options > DLD File Labels menu item and ensure that labels are being stored in the file when the program is compiled.

For CR1000X-series, CR6-series, CR300-series, GRANITE 6, GRANITE 9, GRANITE 10, CR1000, CR3000, and CR800-series dataloggers, you can use the Associate Program option (either from the Connect Screen’s Datalogger menu or from the Setup Screen’s Program tab) to associate a TDF file with a datalogger. TDF stands for Table Definitions File. When a program is compiled for a CR1000X-series, CR6-series, CR300-series, GRANITE 6, GRANITE 9, GRANITE 10, CR1000, CR3000, or CR800-series datalogger a program_name.TDF file is created along with the original program file. This file contains the table definitions for that program. Associating the TDF file with a datalogger can be useful if communication is taking place over a slow or unreliable communications link where the attempt to receive table definitions back from the datalogger fails.
