In a method and system for transmitting messages over a data network, the communication task is used which is implemented on a transmitting microcontroller which determines, on the basis of a routing table, which communication system is used to forward the message to which adjacent microcontroller. A dual-ported RAM is provided between two microcontrollers as one type of communication system.

Method and device for transmitting messages over a data network

In a method and device for controlling several stepping motor modules in printing or copying machines, sets of ramp data are centrally calculated in a computer in a calculation phase and are transmitted via a bus system to one logic unit each in a loading phase. The ramp data are stored in the stepping motor modules in non-volatile memories and are loaded to corresponding main memories depending on operating conditions. When a stepping motor module is operational, the current set of ramp data is transmitted by a control unit. A start signal transmitted by the control unit initiates the conversion of the set of ramp data selected in the corresponding logic unit into impulses of variable distance.
