TACHOGRAPH DATA
From tachograph files to answers
Driver-card and vehicle-unit files go in; verified activities, remaining times and infringement warnings come out.
Every file verified and put to work
Instead of a folder full of .DDD files, PrologEU reads each file, checks that it is genuine, and connects it to the right driver and vehicle.
- Driver-card files, first and second generation (Gen 1 / Gen 2)
- Vehicle-unit files with activities per driver slot
- Digital signature verification against the EU tachograph certificate chain
- GNSS position records from smart tachographs
- Download history and status per driver and vehicle
- Works with files from VDO, Stoneridge and Actia tachographs

Remote download
Collect tachograph data through connected telematics instead of waiting for the truck to return. PrologEU works with Geotab, and other providers can be connected on request. Tell us which provider your fleet uses and we'll check your setup.
Remote download depends on your tachograph, your telematics equipment and your provider's access. We check your setup before you commit.
