The system has a central unit (10) and a number of peripheral modules (20), of which each contains a control circuit (24) and a connected information transmitter/receiver device which is connected to a first and second input/output connection (21,22) of the module. The individual input/output connections are each connected to only one input/output connection of one other module or of the central unit, so that the peripheral module is connected to the central unit either directly or via one or more transmitter/receiver devices to exchange data with it. |
