ZGM: Central gateway module

The Central Gateway Module links all main buses to one another. Examples of a main bus include the FlexRay, MOST, PT-CAN and K-CAN. This enables the Gateway function on the Central Gateway Module to exchange data between the various different bus systems.

When the diagnosis system is connected through the D-CAN (Diagnose-on-CAN), the central gateway module data requests from the diagnosis system to the internal buses. The response telegrams run through the process in the opposite direction.
