Installing DD files
To enable HART communication between a FLXA402 and setup tool, the device description
(DD) file of the FLXA402 needs to be installed in the setup tool. The DD file contains the HART
communication details and menu configurations specific to the FLXA402.
FieldMate is provided with the latest versions of DD files at the time when sold. The current
version of DD files can be downloaded from the following site (*):
