A communication system for an agricultural machine, comprising

• a main control device configured as a central computing and control unit to control a position-accurate switching on and off of distribution processes and/or processing processes of the agricultural machine;
• and
• at least one auxiliary operating component configured to perform an operating function assigned to it as a function of control data from the main control device, independently of the main control device, or as a function of control data from the main control device and independently thereof;
• wherein the main control device and the at least one auxiliary operating component each have at least one Ethernet interface for connection to an Ethernet data network for sending and/or receiving data via the Ethernet data network during the control of the position-accurate switching on and off of distribution processes and/or processing processes, wherein the at least one auxiliary operating component comprises an auxiliary operating component coupled to the main control device in a master-slave configuration.
