Method for Exchanging Data
First Claim
1. A method for exchanging data between a tachograp and a connecting device, the tachograph having a data-transmitting connection to the connecting device, the method comprising the steps of:
- transmitting the data in accordance with a data transmission protocol which provides for the connecting device to cause the tachograph to perform a service by specifying at least one service identifier,assigning internal service identifiers to external service identifiers by the tachograph, wherein the external service identifiers are used when exchanging data with the connecting device, andreplacing external service identifiers of incoming data with corresponding internal service identifiers in accordance with the assignment by a common module.

Abstract
In a method for exchanging data between a tachograph (DTCO) and a terminal device (CALTEST), the data transmission protocol provides for the terminal device (CALTEST) to cause the tachograph (DTCO) to perform a service by indicating at least one service identification (SID). The method further provides for transmitting data in such a way that a flexible compatibility of the tachograph is obtained. The tachograph (DTCO) encompasses an allocation of internal service identifications (IIDS) to external service identifications (EIDS), the external service identifications (EIDS) are used during data exchange with the terminal device (CALTEST), and external service identifications (EIDS) of incoming data are exchanged with matching internal service identifications (IIDS) according to the allocation (mapping list MAP) by a communication module (COMM).

13. A system comprising a tachograph and a connecting device, the tachograph having a data-transmitting connection to the connecting device, wherein the system is operable
to transmit data between the connecting device and the tachograph in accordance with a data transmission protocol which provides for the connecting device to cause the tachograph to perform a service by specifying at least one service identifier, to assign internal service identifiers to external service identifiers by the tachograph, wherein the external service identifiers are used when exchanging data with the connecting device, and to replace external service identifiers of incoming data with corresponding internal service identifiers in accordance with the assignment by a communication module.
