TDF File

This field is only enabled when you are importing a TOA5 or TOACI1 file into a New Table. These file formats do not store data type information in their headers. Therefore, it is recommended that you specify a TDF file associated with the data file. This provides DBImport with the information necessary to more accurately and efficiently map data in the data file into data types supported by the database.

TDF stands for Table Definitions File. When a program is precompiled for a CR1000, CR3000, CR800/850, or CR6 Series datalogger, a program_name.TDF file is created along with the original program file. Both Short Cut and the CRBasic Editor have the option to produce a .TDF file when a program is created or compiled. This file contains the table definitions (table size, variable names, data types, etc.) for that program.

NOTE:

When importing a TOA5 or TOACI1 data file into a new database table, a TDF file is particularly important if you anticipate the need to add data to the table later on via an LNDB/LoggerNet connection.
