Abstract
The system according to the present invention for data transfer between microcomputer devices contains a standard protocol controller, a generally known ethernet controller, for example, as a coupling device instead of the known multipart RAM. Instead of a parallel data connection, the microcomputer devices are coupled to one another via a standardized, serial data connection, for example, ethernet. Using functions of ethernet switches already known, a number of microcomputer devices in the system may be increased.
